I just feel sick about this #blizzard! 😫 We are only catching the very edge of it (others will have a way harder time than us), but all of the #FruitTrees around the house are blooming or buds starting to open & they're all going to be frozen. It's not just the blossoms, it's all the new leaves on all of the plants and trees - they're all going to get torched! 😢😩😫😭😖😤😠 I'm so depressed! The trees would most likely be laden with fruit otherwise! 😭😭😭 #ExtremeTemperatures #ClimateChange #spring

Summerlike heat dome to send #Southwest temperatures soaring past 100 F
A strengthening #HeatDome will send temperatures soaring into the 90s and past 100 degrees across the Southwest, threatening records, accelerating snowmelt and raising #wildfire risk now, then #WaterSupply concerns later.
By Alex Sosnowski, AccuWeather senior meteorologist
Published Mar 13, 2026"Temperatures will climb well into the 90s, with some areas forecast to top 100 degrees Fahrenheit through next week. While those numbers may not seem extreme for the southwestern United States, they are running one to two months ahead of historical averages and could have implications for wildfire risk and water supplies across the interior Southwest later this year.
"A persistent area of high pressure at multiple levels of the atmosphere, known as a heat dome, will intensify in the coming days and may be slow to break down."

Meteorologist warns 'highly unusual' US winter pattern shift is coming
Story by Everett Sloane, 2/5/2026
"A sharp, late-season flip in the jet stream is setting up a winter pattern that looks very different from the one that opened the year, and forecasters say it is not business as usual. A leading Meteorologist has described the looming shift as 'highly unusual,' warning that a distorted #PolarVortex and a recharged storm track could rearrange who gets buried in snow and who finally thaws out. The stakes range from #water supplies in the mountains of the western United States to #EnergyDemand and even #wildlife stress in places that are not built for #ArcticAir.
"The core of the coming change is a dramatic reconfiguration of the polar vortex and the jet stream that steers storms across North America. Instead of a simple, locked-in cold pool over the eastern half of the country, forecasters describe a stretched and wobbling circulation that can send frigid air plunging south while allowing pockets of warmth to surge north. One Meteorologist has framed the setup as 'Highly unusual,' noting that winter weather across the United States is about to change in a big way as the upper-level flow reorganizes over the central and eastern states, a shift detailed in a recent analysis. Instead of the gradual, predictable evolution that textbooks once suggested, the atmosphere is pivoting quickly, with cold and warmth trading places in a matter of days."

We saw a lot of this last year... Not good for the plants (or critters). Temperature extremes can cause hibernating/dormant life-forms to wake up before winter is over!
Experts issue warning about powerful weather phenomenon that could soon impact US: 'This looks to be a prolonged event'
Story by Timothy McGill, November 20, 2025
Excerpt: "The forecast now is calling for the country's rollercoaster ride of temperatures to continue. Weather whiplash saw at least 90 cold records fall from Nov. 9-12, followed by at least 40 record highs broken in a single day, only around a week later. The U.S. could now be on the cusp of a record-breaking cold snap settling in about a week from now.
"Our overheating planet is weakening and destabilizing the #PolarVortex, driven by changes in the Arctic. The region is warming almost four times faster than the global average. Our warming world is supercharging this phenomenon known as #ArcticAmplification."

The new research can now reveal that the algae have a unique ice-gliding ability that allows them to move in #extremetemperatures in the #Arctic
Chukchi Sea expedition
The researchers gathered ice core samples that included the algae, ice-dwelling diatoms, during a 45-day Arctic expedition in the Chukchi Sea aboard the research vessel, owned by the National Science Foundation and operated by the University of Alaska Fairbanks. -
#Greece, #Spain and #Portugal race to contain #wildfires as #EU steps up cross-border help
By DEREK GATOPOULOS and SUMAN NAISHADHAM
August 14, 2025ATHENS, Greece (AP) — "Fire crews in Greece, Spain and Portugal raced to contain wildfires on Thursday, taking advantage of calmer winds that slowed the blazes even as much of southern Europe remained at high risk under hot, dry conditions.
"A drop in wind speeds allowed firefighting aircraft in the three hard-hit countries to step up water drops, concentrating on existing fire zones rather than chasing fast-moving fronts. Authorities warned that #ExtremeTemperatures are likely to persist.
"Spanish authorities reported the death of a 37-year-old volunteer firefighter who sustained severe burns in an area north of #Madrid this week. It was the third reported death in Spain due to the recent fires. Thousands of people were evacuated from their homes in the region and still can not return.
"In Greece, the Fire Service said a major blaze outside the southern port city of #Patras has been contained on the outskirts of urban areas after a large-scale deployment. Three people have been arrested in connection with the fire, which authorities said may have been deliberately set.
"#HighWinds in Greece shifted to different parts of the country on Thursday. Ioannis Kefalogiannis, the civil protection minister, said authorities were bracing for the likelihood of a new round of major fires."

#Japan marks highest-ever temperature of 41.2 C in #Hyogo
By Tomoko Otake, Jul 30, 2025
"Japan recorded the highest ever temperature of 41.2 degrees Celsius on Wednesday, beating the previous high of 41.1 C marked in 2018 and 2020. Authorities are strongly urging people to take precautions to avoid risks of heatstroke.
"The mercury hit the above-human temperature of 41.2 C in the city of Tanba, Hyogo Prefecture, at 14:39, while two cities — #Fukuchiyama in #Kyoto and #Nishiwaki in Hyogo — also recorded extremely high temperatures of 40.6 C and 40 C, respectively.
"Wednesday marked the first day this year that temperatures topping 40 C were recorded, according to NHK. Last year, the city of Mino, Gifu Prefecture, hit that mark on Aug. 16.
"As human-induced climate change drives extreme heat across Japan, the number of people taken to hospitals over heat-related illnesses had surged to 10,804 in the week through Sunday, a huge jump from 5,309 recorded the week before, according to the Fire Management Agency. By prefecture, Tokyo topped the list of such people, at 1,099, followed by Saitama’s 750 and Hokkaido’s 690.
"In Hokkaido, where many people are not acclimated to heat, the number was a significant increase from 247 recorded in the same week last year.
"The agency is urging people to use air conditioners and cooling fans properly and take fluids frequently.
"The ongoing heat wave is likely to continue for several more days. According to the Meteorological Agency, a Pacific high-pressure system will cover much of Japan from Saturday through Monday, bringing extreme heat to wide areas."

#USWeather: Over 2,800 #HighTemperature records set during #HeatWave
A week-long heat wave set over 2,800 record high temperatures in towns across the nation, with some spots measuring their hottest June or all-time temperatures.
By Jesse Ferrell & Brian Lada
Published Jun 23, 2025"A total of 955 daily high temperature records and 1,899 daily high minimum (warm night) records were tied or broken during the last week's heat wave.
"Records dating back to the 1800s were shattered as an early-summer heat wave roasted large areas of the central and eastern United States. AccuWeather RealFeel® Temperatures blew past the 100-degree mark, air conditioners were on full blast, and cities opened cooling centers to help people cope with the intense heat.
" 'This is an incredibly hot and steamy heat wave for the month of June,' AccuWeather Chief On-Air Meteorologist Bernie Rayno said.
Tuesday's heat breaks 137-year-old record
"The heat wave peaked on Tuesday, and it wasn't just the hottest day of 2025, but the hottest weather many residents in the Northeast have experienced in over a decade.
"The mercury soared to 102 degrees in Boston on Tuesday afternoon, making it the hottest day in the city since July 22, 2011, when it reached 103. Philadelphia also notched its first 100-degree day since July 18, 2012.
"In New York City, the temperature fell just shy of hitting triple digits, but the high of 99 degrees was still enough to beat the previous daily record for the date, surpassing the high of 96 degrees set on June 24, 1888. Some areas not far from Central Park, where the official weather observations for the city are taken, did manage to hit 100 degrees, including Newark (103) and John F. Kennedy International Airport (102).
"Other cities across the region that reached 100 F on Tuesday afternoon include Hartford, Connecticut; Providence, Rhode Island; Wilmington and Dover, Delaware; and Manchester, New Hampshire.
"Monthly and hourly records were also set
"Illustrating how unusual and early the heat wave was, a thermometer in #AugustaME, recorded 100 degrees, tying their all-time record high set on Aug. 5, 1955. It joined 13 other stations where the temperature had never been recorded hotter.
"Many cities had never been as hot in June as they were Tuesday. Stations reporting their hottest June temperatures on record include #NewarkNJ, at 103 (tied); #NewYorkCity (Kennedy & LaGuardia at 102 and 101, a tie); Islip, New York at 101; Portland and #BangorME, at 99 and 98, a tie; and Mount Pocono, Pennsylvania, at 93, recorded on Monday. A total of 90 stations set June records.
"The heat came early in the day, with #Philadelphia setting or tying new hourly record highs for 9 a.m., 7 a.m., and 5 a.m., and New York City (JFK Airport) notching new or tied extreme highs at 3 a.m., 8 a.m., 1 p.m., 4 p.m., and 5 p.m, according to the Iowa Environmental Mesonet. For June, Philadelphia's hourly temperatures had never been higher for all but two hours of the day.
Monday's records
"The first full week of astronomical summer wasted no time warming up, with many thermometers across the region reaching levels they haven't hit in years.
"#Baltimore's Inner Harbor was one of the hottest spots on Monday, with a high of 104 F. The high humidity and strong summer sun made it dangerously hot outside, with the AccuWeather RealFeel® Temperature topping out at 113 degrees. To put this heat into perspective, 113 degrees is the historical average high temperature in Death Valley in mid-June.
"#NewarkNJ, reached 101 degrees, breaking its daily record of 99, and #RaleighNC, tied its daily record of 100, set last year.
"Although other weather stations broke records, they were all below 100 degrees. Most notably, the temperature at Mount Pocono, Pennsylvania, rose to 93 degrees, breaking the daily record and setting June's highest reading. This was the first 90-degree day at Mount Pocono since 2013.
Sunday's records"On Sunday, three weather stations broke the high temperature records for the date. Alpena, Michigan, hit 97 degrees Fahrenheit, breaking the previous record of 93 set in 1975. In #ValleyNE, the mercury pushed up to 94 degrees, breaking the old record of 91 from 2023. And in #MarquetteMI, the old record of 90 degrees, on this date in 1995, was smashed by a reading of 93.
"But it wasn't just daily record highs. Records for warm nights were also broken at breakneck speed. Saturday night tied the all-time high minimum historical record for Green Bay, Wisconsin, at 79 degrees, previously achieved in July 4, 1897, and July 30, 1916. Wausau, Wisconsin, didn't cool below 78 degrees, which had previously happened only on July 4, 1999. The fact that these records were previously recorded in July is an indicator of how early this severe heat wave is.
"Record warm nights for June were also set at La Crosse, Wisconsin, (80 degrees) and Mason City, Iowa, (77 degrees) Saturday night.
"A total of 255 record warm nights for June were recorded over the last week, with 59 of those new records the warmest nights ever recorded at the stations."

"The heat came early in the day, with #Philadelphia setting or tying new hourly record highs for 9 a.m., 7 a.m., and 5 a.m., and New York City (JFK Airport) notching new or tied extreme highs at 3 a.m., 8 a.m., 1 p.m., 4 p.m., and 5 p.m, according to the Iowa Environmental Mesonet. For June, Philadelphia's hourly temperatures had never been higher for all but two hours of the day.
Monday's records
"The first full week of astronomical summer wasted no time warming up, with many thermometers across the region reaching levels they haven't hit in years.
"#Baltimore's Inner Harbor was one of the hottest spots on Monday, with a high of 104 F. The high humidity and strong summer sun made it dangerously hot outside, with the AccuWeather RealFeel® Temperature topping out at 113 degrees. To put this heat into perspective, 113 degrees is the historical average high temperature in Death Valley in mid-June.
"#NewarkNJ, reached 101 degrees, breaking its daily record of 99, and #RaleighNC, tied its daily record of 100, set last year.
"Although other weather stations broke records, they were all below 100 degrees. Most notably, the temperature at Mount Pocono, Pennsylvania, rose to 93 degrees, breaking the daily record and setting June's highest reading. This was the first 90-degree day at Mount Pocono since 2013.
Sunday's records"On Sunday, three weather stations broke the high temperature records for the date. Alpena, Michigan, hit 97 degrees Fahrenheit, breaking the previous record of 93 set in 1975. In #ValleyNE, the mercury pushed up to 94 degrees, breaking the old record of 91 from 2023. And in #MarquetteMI, the old record of 90 degrees, on this date in 1995, was smashed by a reading of 93.
"But it wasn't just daily record highs. Records for warm nights were also broken at breakneck speed. Saturday night tied the all-time high minimum historical record for Green Bay, Wisconsin, at 79 degrees, previously achieved in July 4, 1897, and July 30, 1916. Wausau, Wisconsin, didn't cool below 78 degrees, which had previously happened only on July 4, 1999. The fact that these records were previously recorded in July is an indicator of how early this severe heat wave is.
"Record warm nights for June were also set at La Crosse, Wisconsin, (80 degrees) and Mason City, Iowa, (77 degrees) Saturday night.
"A total of 255 record warm nights for June were recorded over the last week, with 59 of those new records the warmest nights ever recorded at the stations."

#USWeather: Over 2,800 #HighTemperature records set during #HeatWave
A week-long heat wave set over 2,800 record high temperatures in towns across the nation, with some spots measuring their hottest June or all-time temperatures.
By Jesse Ferrell & Brian Lada
Published Jun 23, 2025"A total of 955 daily high temperature records and 1,899 daily high minimum (warm night) records were tied or broken during the last week's heat wave.
"Records dating back to the 1800s were shattered as an early-summer heat wave roasted large areas of the central and eastern United States. AccuWeather RealFeel® Temperatures blew past the 100-degree mark, air conditioners were on full blast, and cities opened cooling centers to help people cope with the intense heat.
" 'This is an incredibly hot and steamy heat wave for the month of June,' AccuWeather Chief On-Air Meteorologist Bernie Rayno said.
Tuesday's heat breaks 137-year-old record
"The heat wave peaked on Tuesday, and it wasn't just the hottest day of 2025, but the hottest weather many residents in the Northeast have experienced in over a decade.
"The mercury soared to 102 degrees in Boston on Tuesday afternoon, making it the hottest day in the city since July 22, 2011, when it reached 103. Philadelphia also notched its first 100-degree day since July 18, 2012.
"In New York City, the temperature fell just shy of hitting triple digits, but the high of 99 degrees was still enough to beat the previous daily record for the date, surpassing the high of 96 degrees set on June 24, 1888. Some areas not far from Central Park, where the official weather observations for the city are taken, did manage to hit 100 degrees, including Newark (103) and John F. Kennedy International Airport (102).
"Other cities across the region that reached 100 F on Tuesday afternoon include Hartford, Connecticut; Providence, Rhode Island; Wilmington and Dover, Delaware; and Manchester, New Hampshire.
"Monthly and hourly records were also set
"Illustrating how unusual and early the heat wave was, a thermometer in #AugustaME, recorded 100 degrees, tying their all-time record high set on Aug. 5, 1955. It joined 13 other stations where the temperature had never been recorded hotter.
"Many cities had never been as hot in June as they were Tuesday. Stations reporting their hottest June temperatures on record include #NewarkNJ, at 103 (tied); #NewYorkCity (Kennedy & LaGuardia at 102 and 101, a tie); Islip, New York at 101; Portland and #BangorME, at 99 and 98, a tie; and Mount Pocono, Pennsylvania, at 93, recorded on Monday.

So, the CDC's Heat & Health Tracker website has been gutted (thanks #DOGE). "This website is no longer being maintained, and no new data will be added." The page does suggest to check out the NWS HeatRisk website, which is experimental and allegedly up for a short time only.
"The NWS HeatRisk is an experimental color-numeric-based index that provides a forecast risk of heat-related impacts to occur over a 24-hour period. HeatRisk takes into consideration:
- How unusual the heat is for the time of the year
- The duration of the heat including both daytime and nighttime temperatures
- If those temperatures pose an elevated risk of heat-related impacts based on data from the CDC"This index is supplementary to official NWS heat products and is meant to provide risk guidance for those decision makers and heat-sensitive populations who need to take actions at levels that may be below current NWS heat product levels.

A favorite of mine, Windy.com -- which has had significant upgrades!
"In 2021, two new #ICON forecast models were integrated - ICON-D2 with local coverage for central and west #Europe and ICON Global. Thousands of new air quality stations monitoring primary pollutants worldwide were added from our partners #OpenAQ and #PurpleAir to fight #AirInequality.
"Several new layers were launched - Tidal currents featuring high-resolution data; the Sea currents dataset was updated; Thermals layer with soaring forecast for glider and paraglider pilots; Drought monitoring layers - Soil moisture, Moisture anomaly, and #Drought intensity, monitoring global drought.
"We also expanded into the wear OS category and introduced Windy Apple Watch App. The 3D Globe mode was brought back for most layers (desktop only), including the Hurricane Tracker.
"In 2022, we launched several new features and improved existing ones. In the beginning of the year, we added a new #radioactivity set of stations as a POI overlay and partnered with SaveEcoBot, run by a non-profit organisation SaveDnipro, and obtained a broad spectrum of environmental data sources in #Ukraine and offer them in an easy-to-access way to our users and other affected communities for free.
New local models HRRR for the US and ACCESS model for Australia were added, along with a set of layers wet-bulb temperature, UV Index and Solar power.
With release of iOS16, the Windy.com iOS app got LockScreen widgets, which can be placed on the phones's locked screen. A new significant iOS feature."For the #HurricaneSeason, we launched redesigned and upgraded our Hurricane Tracker and added multimodel forecast & LIVE satellite visualization. Users in the US could also appreciate an improved radar resolution and coverage."

Central #Maine smashes third temperature record in a week
Augusta's high temperature Wednesday tied the warmest temperature ever recorded at the site in the month of November
by Ethan Horton, November 6, 2024
AUGUSTA — "Central Maine set yet another heat-related record Wednesday, marking the third time in the past week a daily temperature record has been broken.
"Wednesday’s unofficial high temperature reached 76 F (24.4 C) in #AugustaMaine and 73 degrees (22.7 C) in #WatervilleMaine, breaking the local record of 72 degrees (22.2 C), set in 2022. The area also broke records on Oct. 31 and Nov. 1, easily surpassing high temperature records set in 1956 and 2003, respectively.
"The #PortlandMaine area broke a record for the entire month Wednesday: The high of 79 degrees F (26.1 C) shattered the warmest temperature ever recorded at the site in the month of November, set at 75 degrees F (23.8 C) on Nov. 5, 2022. Augusta’s high temperature Wednesday tied the area’s all-time November record."

From 2011:
In Tennessee, #HeatWaves Diminish #Nuclear Power Output
By Alyson Kenward
April 10, 2011"On July 8, 2010, as the temperature in downtown Decatur, Alabama climbed to a sweltering 98°F, operators at the #BrownsFerry #NuclearPowerPlant a few miles outside of town realized they had only one option to avoid violating their #environmental permit: turn down the reactors. For days, the Tennessee Valley Authority (#TVA), which owns the nuclear plant, had kept a watchful eye on the rising mercury, knowing that more heat outside could spell trouble inside the facility. When the #TennesseeRiver, whose adjacent waters are used to cool the reactors, finally hit 90°F and forced Browns Ferry to run at only half of their regular power output, the TVA hoped the hot spell would last just a few days.
"Eight weeks of unrelenting heat later, the plant was still running at half its capacity, robbing the grid of power it desperately needed when electricity demand from #AirConditioners and fans was at its peak. The total cost of the lost power over that time? More than $50 million dollars, all of which was paid for by TVA’s customers in Tennessee.
"The Browns Ferry nuclear plant, located on the Wheeler Reservoir along the Tennessee River near Athens, Alabama. It has three reactors, each producing about 1000 megawatts of electricity. Credit: Nuclear Regulatory Commission.
“'Last summer, the water in the Tennessee River warmed up early and stayed warm,' says TVA spokesman Ray Golden. 'When it got hot again in July and August, we were impacted by that and had to reduce power at the plant and get it from somewhere else.'
"With river water so warm, the #NuclearPlant couldn’t draw in as much water as usual to cool the facility's three reactors, or else the water it pumped back into the river could be hot enough to harm the local #ecosystem, says Golden. But for every day that the Browns Ferry plant ran at 50 percent of its maximum output, the TVA had to spent $1 million more than usual to purchase power from somewhere else, he says.
"What happened in northern Alabama last summer, at the largest of TVA's nuclear power plants, did not present a human safety concern. Operators knew there was never a risk of an explosion or nuclear meltdown, nor was there a threat of leaking radioactive material. But the prolonged spell of hot weather put the TVA at risk of violating environmental permits, with hefty fines as one consequence and potential harm to the Tennessee River ecosystem as another.
"It’s not the first time high temperatures have affected the performance of the Browns Ferry plant, and extreme heat is a growing concern for power plant operators across the #Southeast. While some nuclear plants can improve their cooling procedures to cope with the intake of warmer water, the upgrades can cost hundreds of millions of dollars and still don’t offer an indefinite defense against extreme heat. Because scientists say the Southeast (like many other parts of the world) can expect to see more frequent and intense heat waves by the end of this century, the problems for nuclear power and the people that rely on it for electricity may only be beginning.
#ExtremeHeat Limits Nuclear Energy Production
"The disaster still unfolding at Japan’s #FukushimaDaiichi nuclear plant has refocused America's attention on nuclear power, calling into question its future role in the country's energy portfolio. Many advocates of nuclear power say that we need to maintain — and even expand — nuclear power to get away from using fossil fuels, such as coal, and to help lower greenhouse gas emissions.
"But nuclear power has a paradoxical relationship with #ClimateChange. Even though it might help mitigate long-term #GlobalWarming, nuclear power is already being challenged by rising temperatures and the increasing number of heat waves around the world. Throughout the last decade, several plants have had to reduce electricity production during heat waves, just when when electricity demand typically reaches peak levels.
“'It’s a dilemma between mitigation of climate change, and adaptation to it,' says Natalie Kopytko, an energy policy doctoral student at the University of York in England. Having recently studied the ways in which climate change could have a negative impact on nuclear power, she says nuclear power is caught in the middle because it could be used to help lower greenhouse gas emissions, but global warming is making the technology less effective at providing electricity."

Nuclear Power Plants: #NRC Should Take Actions to Fully Consider the Potential Effects of #ClimateChange
GAO-24-106326 Published: Apr 02, 2024.
"Climate change is likely to exacerbate natural hazards—such as #floods and #drought. The risks to nuclear power plants from such hazards include damage to systems and equipment that ensure safe operation.
"The Nuclear Regulatory Commission's oversight process includes addressing safety risks at these plants. However, NRC doesn't fully consider potential increases in risk from climate change. For example, NRC mostly uses historical data to identify and assess safety risks, rather than data from future climate projections.
"We recommended that NRC fully address climate risks to nuclear power plants.
"Climate change is expected to exacerbate natural hazards—including heat, drought, #wildfires, #flooding, #hurricanes, and #SeaLevelRise. In addition, climate change may affect #ExtremeCold weather events. Risks to nuclear power plants from these hazards include loss of offsite power, damage to systems and equipment, and diminished cooling capacity, potentially resulting in reduced operations or plant shutdowns.
"The Nuclear Regulatory Commission (NRC) addresses risks to the safety of nuclear power plants, including risks from natural hazards, in its licensing and oversight processes. Following the tsunami that led to the 2011 accident at Japan's #FukushimaDaiichi nuclear power plant, NRC took additional actions to address risks from natural hazards. These include requiring safety margins in reactor designs, measures to prevent radioactive releases should a natural hazard event exceed what a plant was designed to withstand, and maintenance of backup equipment related to safety functions.
"However, NRC's actions to address risks from natural hazards do not fully consider potential climate change effects. For example, NRC primarily uses historical data in its licensing and oversight processes rather than climate projections data. NRC officials GAO interviewed said they believe their current processes provide an adequate margin of safety to address climate risks.
"However, NRC has not conducted an assessment to demonstrate that this is the case. Assessing its processes to determine whether they adequately address the potential for increased risks from climate change would help ensure NRC fully considers risks to existing and proposed plants. Specifically, identifying any gaps in its processes and developing a plan to address them, including by using climate projections data, would help ensure that NRC adopts a more comprehensive approach for assessing risks and is better able to fulfill its mission to protect public health and safety."

Dangerous heat continues to bake areas of the West from #WashingtonState to #Arizona
A prolonged and expansive heat wave will continue across the West into early week, resulting in record-breaking highs from the #Cascades to the #DesertSouthwest.
"The all-time record of 117 in #LasVegas could be broken Sunday, and daily records in Vegas could be challenged or broken nearly every day from today through at least next Thursday."
By Alyssa Glenny, AccuWeather Meteorologist
Published Jul 6, 2024
Key Takeaways:
"Over the upcoming days, all-time record high temperatures will be challenged across portions of the West. Daytime highs from Washington to Arizona can range upwards of 100 F, with some Desert Southwest locations soaring above 115 F daily.
"Factors such as a recent lack of rainfall, low relative humidity levels and stifling temperatures will create an elevated #wildfire threat.
"Harsh conditions over the upcoming days can dramatically raise the risk for heat-related illnesses, such as heat stroke and heat exhaustion.
UV indexes categorized as 'extreme'
Copious amounts of sunshine will continue to expand across the West through at least midweek, providing little relief for residents in terms of any shade gleaming from cloud cover. In the heart of the Southwest, locations like Las Vegas and Phoenix are forecast to have max ultraviolet (UV) index levels categorized as extreme for much of this week, ranging between 11 and 12."

"Temperatures will build to their highest marks in years across the Midwest and Northeast and stay at sizzling levels for days as #MotherNature cranks up the heat ahead of astronomical summer, which begins Thursday, June 20, at 4:50 p.m. EDT.
"AccuWeather's long-range team has been sounding the alarm for more than a week on building heat in the East during the third week of June that would put millions at the mercy of a prolonged stretch of 90-degree Fahrenheit temperatures. The longevity of the intense heat will put additional strain on residents and #ElectricalInfrastructure.
"For many in the #Midwest and #Northeast, this week will constitute the first official heat wave of the season, which, in this part of the country, is defined as three or more consecutive days of at least 90-degree temperatures. Heat alerts have been issued for more than a dozen states, stretching from #Iowa and #Illinois to #Maine, as the summer swelter takes shape."
