'Dangerous' air quality in Detroit, Minneapolis as thick wildfire smoke shrouds the sky for millions
Smoke from wildfires burning in Ontario have caused air quality to reach "dangerous" levels across Canada, and the northeastern and midwestern United States. And it could get worse before conditions improve.
By Brian Lada, AccuWeather meteorologist
Published Jul 15, 2026 11:50 AM EDT | Updated Jul 16, 2026
" Massive plumes of smoke are descending across parts of Canada and the United States, creating dangerous air quality and scenes reminiscent of the historic wildfire smoke outbreak from three summers ago.
" 'In 2023, a major fire outbreak in Quebec caused days of unhealthy air quality in the northeastern U.S.,' AccuWeather Vice President of Forecast Operations Dan DePodwin said. 'This event could cause similar levels of poor air quality in spots.'
"Air quality alerts have been issued for millions of people, including across all of #Connecticut, #Delaware, #Massachusetts, #Michigan, #NewHampshire, #NewJersey, #NewYork, #Ohio, #Pennsylvania, #RhodeIsland and #Wisconsin.
"Over 800 wildfires are currently burning across Canada, including dozens that are out of control across western #Ontario, the source of most of the smoke. 'Many of these fires may have been started by lightning,' AccuWeather Senior Meteorologist Brett Anderson said.
"On Wednesday, #Toronto had some of the worst air quality in North America, reaching 'very unhealthy' levels with an AQI of 220. #BostonMA was not far behind with an unhealthy AQI of 147.
" 'When the AQI climbs into the 150+ range for a full day outside, that’s in the ballpark of [smoking] 7 to 9 cigarettes,' Dr. Jonathan M. Tan, division chief of General Anesthesiology at Children’s Hospital of Philadelphia, told AccuWeather.
"Conditions deteriorated by Thursday morning, with widespread "dangerous" air quality across nearly all the Great Lakes region and into parts of the Northeast. Minneapolis and Duluth, Minnesota, as well as Detroit, were among the worst cities at daybreak Thursday, with AQIs over 340.
" 'Any exposure to the air, even for a few minutes, can lead to serious health effects on everybody,' Plume Labs said.
Avoid outdoor activities.' "#CanadianWildfires #CRBox #AirQuality

Canadian #wildfire smoke turns air hazardous in the US #Midwest. Officials say stay inside
By TAMMY WEBBER and PHILIP MARCELO, July 16, 2026
NEW YORK (AP) — "Heavy, pungent smoke from #CanadianWildfires darkened skies in the U.S. on Thursday from the #GreatLakes to parts of the #EastCoast, reducing visibility for commuters and prompting warnings that air quality could make being outside dangerous.
"#Detroit’s air quality was among the worst in the world for major cities, as a lingering high pressure system trapped smoke from dozens of fires in Canada and northern Minnesota, said Steven Freitag, a National Weather Service meteorologist in Pontiac, Michigan.
" 'Sure enough, it arrived in force here and it’s really pretty extreme levels,' said Freitag, who noted that visibility in some areas was reduced to a half mile.
"Omar Mitchell wore a mask as he walked to his restaurant in Detroit. He said he urged his employees to do the same.
" 'It’s scary,' Mitchell, 50, said as he looked at the sky. 'You don’t know necessarily what the side effects may be. That’s days or months later.'
"Cities across the Great Lakes states registered air quality ranging from unhealthy to hazardous — which means it’s unhealthy for anyone, regardless of health conditions. Microscopic particles can lodge deep in the lungs and enter the bloodstream, leading to heart and lung problems and contributing to other long-term health issues.
"All of #Michigan and much of #Minnesota were under a hazardous #AirQualityAlert. In the Chicago area, air quality ranged from very unhealthy to hazardous.
"National Weather Service meteorologist Jake Petr said even if winds from the northwest clear skies as expected later this week, the smoky air could keep returning until the fires are out. That could take weeks or longer.
" 'Anytime we have something that could bring air from that region until the fires are over, it could conceivably dip back into the area,' Petr said.
"In #SaintPaulMN, the air was 'glowing yellow,' said Brent Williams, head of the soil, water and climate department at the University of Minnesota, who said the area 'could be looking at weeks to months of continued smoke and flare-ups off and on as the winds blow in different directions.'
"A study published this year found that long-term exposure to tiny particles from wildfire smoke contributed to an average of 24,100 deaths a year in the lower 48 states. Long-term exposure can make existing health problems worse and lead to a range of chronic and deadly health issues, including respiratory illness, cardiovascular and neurological diseases, and premature death."

If it weren't for the #smoke, I likely would have gone, even with the #rain Sat/ Sun.
Took Th/Fri off, cuz I don't set up the #tent Friday night & tear it down Sunday morning, I need 3 nights.
But it's #sunny tomorrow & lower PMI*, especially at a different #campground (which I haven't visited yet this #season) where I'll do a #DayTrip instead ( #masked, 'natch, if it's over 100).

#Wildfire Smoke Spreads Across the #Northeast as Temperatures Spike
A heat dome is responsible for miserably high temperatures, and it’s also helping to push smoke from wildfires to the east.
By Judson Jones and Mark Walker
July 15, 2026"From the windows of office buildings across Manhattan, the blue sky turned hazy on Tuesday as wildfire smoke from #Canada and the #GreatLakes slipped across the Northeast, prompting alerts in some places about poor air quality.
"The haze is expected to continue on Wednesday, and even to worsen in some places, as the same heat dome that is pushing temperatures close to 100 degrees across much of eastern Canada and the United States traps the smoke from faraway wildfires close to the ground.
"In New York, city officials warned of 'the possibility of deteriorating air quality' throughout the day Wednesday, but noted that even the most severe forecasts for did not approach the levels seen in 2023, when the Canadian wildfire smoke sent the city’s air quality index surging to dangerous levels. Still, they said, echoing the warnings of officials across the region, people with health conditions that make them sensitive to polluted air should take caution.
"The heat dome, an area of high pressure in the atmosphere, was visible on satellite imagery on Tuesday as an area of clear sky over the middle of the country, where the surrounding air moves clockwise. On the ground, it manifests as a hot, humid and smoky stew that can make just stepping outdoors an unpleasant task.
"Across much of the United States and southern Canada, weather officials have placed tens of millions of people under heat warnings, with high temperatures from the upper 90s to above 100 degrees expected in many places on Wednesday."The National Weather Service said that nearly 100 million people from the Dakotas into New England would be under its 'major' or 'extreme' warning levels for dangerous heat. Environment Canada, the country’s weather service, said that, through Wednesday, southern Ontario would be under an orange alert, the second most severe in its three-tier system."

#HeatDome to broil #WesternUS ahead of North American #monsoon
A new heat dome is building in the United States this week. This time it will focus on the West first, then shift toward the Midwest. Storms associated with the #NorthAmericanMonsoon will follow the heat in the West.
By Alex Sosnowski, Jul 7, 2026
Excerpt: "As the heat wave crests over the interior West, an annual phenomenon will take place. Moisture will begin to trickle in from Mexico at first, then pick up more steam later this week to next week. A surge in humidity levels, along with a flip of the breeze from the west to the south, is known as the North American monsoon.
" 'There should be a slow propagation of thunderstorm activity from south to north over the interior West that should start with spotty activity at first then become somewhat more widespread by next week,' Pastelok said.
" 'Helping that activity will be an eastward shift of the high-pressure heat dome,' AccuWeather Meteorologist Brandon Buckingham said. 'The circulation around the high will help to pump moisture in more freely over much of the West beginning this weekend and more so next week.'
"Many of the early storms over the Southwest may bring little or no rain but gusty #winds and #lightning strikes. The gusty winds can kick up considerable amounts of #dust, creating large #DustStorms or #haboobs. Lightning strikes with no rain can set off scores of new #wildfires, while gusty winds around the storms can fan the new fires and existing large blazes.
"The nature of the heat dome will trap smoke in the region, which can reduce the visibility, create a hazy or milky-looking sky and create #AirQuality dangers for some individuals. "

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."

If your area has nasty smoke right now and you are sick of having to keep checking a website to get the current AQI I made a small internet enabled LED project that glows with the current AQI color. Only needs a NodeMCU/Feather, a NeoPixel Jewel or Ring and some Dupont type wires to connect. See https://www.instructables.com/PurpleAir-Air-Quality-Status-LED-Display/ for really simple instructions and code. Code also here; https://github.com/jeff-luszcz/PurpleTheopolis #arduino #nodemcu #neopixel #aqi #smoke
