It’s a mixed weather bag around Minnesota into Wednesday. We’ve got summery temperatures, some wildfire smoke and a few scattered thunderstorms in the short range forecast.

A weak low pressure wave is sparking scattered thunderstorms in western Minnesota that will move east through the night into Wednesday morning. But the cells will run into more stable air as they cross Minnesota overnight. Most models fade the storms by the time they can reach the Twin Cities and eastern Minnesota early Wednesday morning.

National Oceanic and Atmospheric Administration’s HRRR model shows the fading storm trends between 4 p.m. Tuesday and 6 a.m. Wednesday.

There is a marginal or low risk for a couple severe cells for western Minnesota overnight into Wednesday morning.

Temperatures Wednesday will remain on the summery side with 80s and just a slight chance for isolated thunderstorms. Temperatures this week will peak in the steamy low 90s on Friday across the south.

Air quality is good to moderate across most of Minnesota as of Tuesday afternoon. But there are some unhealthy readings in the northeast. 

Air quality should improve as we move through the week thanks to southerly winds. But another smoke wave may arrive behind the next cold front this weekend. Some of the Canadian wildfire zones will get some rain this week. We’ll have to see how thick the smoke layers are that eventually blow in from the northwest this weekend.

Here’s the latest forecast discussion from MPCA.

MPCA tells me we’re up to 33 air quality alerts issued in Minnesota so far this year. That’s just 8 behind the record of 41 set in 2023. Unfortunately we have a chance of exceeding that record this year if alerts keep coming at the same pace.
