Wisconsin DNR: Limit time outside due to Canadian wildfire smoke
MADISON, Wis. (WFRV) – Wisconsinites are once again being asked to limit their time outdoors on Tuesday into Wednesday due to ongoing air quality advisories resulting from the Canadian wildfire smoke.
According to a release from the Wisconsin DNR, the smoke will be moving across the state throughout the day from the northwest to the southeast.

The DNR has also announced an advisory for particulate matter < 2.5 microns (RED). Health impacts are reaching the unhealthy level and could have short-term spikes in the very unhealthy level.
Those with heart or lung disease, older adults, and children are advised to make their outdoor activities shorter and less intense. DNR officials say to consider moving outdoor activities inside if applicable.
Other ways to stay protected from wildfire smoke are as follows:
Check your local air quality index

Stay indoors
Close doors and windows
Avoid activities that increase indoor pollution: vacuuming, frying food, burning candles, or using gas-powered appliances.
Install a high-efficiency air filter.
Use an N95 mask if outdoors for long periods.
This is the second time this year that an air quality advisory has been issued in the Badger State as a result of the Canadian wildfire smoke. This specific advisory is predicted to last from noon on Tuesday through noon on Wednesday.

Canada's wildfire season is off to a destructive start. This satellite data shows just how bad
While images of wildfires capture their ferocity, data can provide insight into how bad a fire season is. Such is the case with two graphics, powered by satellite data, that showcase a Canadian wildfire season off to a wild—and scary—start. Twice a day a NASA satellite sends images to the ground, giving a real-time view of where fires are burning. This is especially useful for remote areas where no sensors are stationed. As of Tuesday that satellite had picked up four times as many fire hot spots across Canada than is typical for early June. That's more than any year since the satellite began transmitting in 2012, except 2023, according to data from Global Forest Watch. Though the satellite has recorded thousands of hot spots so far this year, that does not mean there are actually that many active fires. Each hot spot could be detected repeatedly over the course of days. And because each detection is about the size of 26 football fields, it can represent part of a much larger blaze, said James MacCarthy, wildfire research manager at Global Forest Watch. Based on data from the Canadian Interagency Forest Fire Centre, about 200 fires are actively burning in Canada and have consumed about 7,700 square miles (19,900 square kilometers) of terrain, most of it in the last week. Only 2023 saw such high numbers so early in Canada's fire season, which runs from April through October. That year wildfires burned a record 67,000 square miles—more than twice the surface area of Lake Superior, the largest of the Great Lakes. Taken together, the hot spots and acres burned mean 2025 is the second-worst start to the season in years. 'A warm and dry finish to May and early June has created a significant fire season,' said Liam Buchart, a fire weather specialist with the Canadian Forest Service. The weather conditions are made more likely by climate change and encourage wildfires to start. That means even though 90% of wildfires in Manitoba this year have been human-caused, according to the provincial government, climate change helps enable their spread. 'Climate change is creating the conditions that make it more likely that human-caused fires are going to spread, or even start,' MacCarthy said. 'It might be a human starting it, but it's going to spread quickly because now there's hot and dry conditions that are occurring more frequently and more intensely than they have in the past.' The hot and dry weather is likely to to continue for at least the next week across Manitoba, Saskatchewan and Alberta, according to Natural Resources Canada. The agency's forecasts also call for 'a warmer and drier than normal July and August for large portions of Canada,' Buchart said. 'The remainder of the fire season looks to remain above normal, especially over the northern prairie provinces and southern British Columbia,' he said.

Warm & muggy Thursday sees a few afternoon downpours; staying unsettled heading into weekend
Thursday morning sees temps in the 60s for the lowlands and 50s for the high terrain in the eastern mountains. Cloud cover will build in this morning combined with some haze from the Canadian wildfires. While an isolated sprinkle can't be ruled out this morning, our best chances for rain will hold off until this afternoon and evening. No severe weather is expected today, but the humidity combined with daytime highs near 80, will create some slow moving downpours. Thursday evening will bring in some hit or miss showers and general thunderstorms early on. After sunset, any showers and storms will lose energy quickly, allowing them to dissipate overnight. Expect a muggy and warm overnight with some patchy fog along areas that saw some showers earlier in the day. Overnight lows will be in the low 60s. Friday starts with some passing showers in the morning, but we'll have some dry time mixed in. As a cold front gets closer, combined with the humidity and daytime highs reaching near 80 again, scattered showers and storms will be a good bet during the afternoon and evening. One or two strong to severe storms can't be ruled out with small hail and damaging winds. Our severe threat will wane overnight as our cold front passes. Saturday sees our cold front pass through during the morning. This means scattered showers and rumbles of thunder will be a good bet during the morning followed by some breaks at times. If we get enough breaks here or there, scattered rain and even a few thunderstorms will linger into the afternoon and evening. Similar to Friday, one or two strong to severe storms are on the table with small hail and damaging winds, but the threat is a low one. Highs will be a little cooler in the middle 70s. Our Interactive Radar Sunday brings a low pressure system during the morning. This means we can expect another round of scattered showers for those heading out to church. As this low pressure system passes through, more chances for rain and storms will linger into the afternoon. Expect daytime highs to stay in the middle 70s. Monday sees a warm front lift off to the northeast as we wait for our next cold front to arrive on Tuesday. Even so, isolated to scattered showers will be around on Monday as daytime highs climb into the upper 70s. Tuesday brings in a cold front, igniting more chance for scattered showers and storms. Keep the rain jackets on standby once again with daytime highs struggling to get into the middle 70s. #WeatherTogether In your extended forecast, can't rule out an isolated sprinkle early on Wednesday morning but the second half is trending to be a dry one. Thursday sees high pressure build in, allowing us to dry out. This looks to be short lived however as another system arrives by next Saturday with more chances for showers and storms.

Chicago weather: Air quality alert called for a 2nd straight day as Canadian wildfires continue
An air quality alert is in effect until midnight Thursday for the Chicago area as Canadian wildfires continue, officials said. The Illinois Environmental Protection Agency declared an Air Pollution Action Day because widespread ozone and or particulate levels are expected to be at or above the unhealthy for sensitive groups category. Officials said wildfire smoke is expected to continue to affect those levels Thursday and Friday, officials said. The same air alerts were also issued on Wednesday. Current morning conditions at O'Hare International Airport are mostly cloudy with haze at 60 degrees. At Midway Airport, conditions are foggy and misty at 61 degrees. On Thursday, highs in the upper 50s are expected. Plumes of smoke are blanketing large swaths of the U.S. and parts of Europe, which presents risks for those breathing it. The Midwest, Northeast and Great Lakes regions of the U.S. have 'very unhealthy' air quality, according to the Environmental Protection Agency, and experts say people should take precautions. .
