Overnight fog is thinning rapidly across northern Minnesota this Wednesday morning. Temperatures and dew points will be comfortable throughout the day. Afternoon highs should range from the upper 60s to mid 70s in northwestern Minnesota to the mid 80s in the southeast. The Twin Cities will enjoy a high near 84, which is just a couple degrees warmer than average. Dew points will be mostly in the non-sticky 50s.
Wildfire smoke should thin
Although Canadian wildfire smoke has remained mostly aloft recently, some of it has mixed to the ground. The air quality forecast for Wednesday from the Minnesota Pollution Control Agency is for smoke conditions to be unhealthy for sensitive groups for portions of central Minnesota. Smoke should thin Wednesday afternoon.
Several chances of storms, beginning Wednesday
Isolated to scattered thunderstorms broke out across northern Minnesota on Tuesday. The cold front responsible for the storms has sagged southward and should trigger broader areas of isolated to scattered storms on Wednesday. While most of these storms won’t develop until Wednesday afternoon and evening, the first storms of the day blew up over central Minnesota in the 8 a.m. hour.
Some storms later on Wednesday could be strong or severe with wind and hail. The updated marginal risk (level 1 of 5) of severe weather from South Dakota eastward to much of Wisconsin and Upper Michigan was changed very little from the risk posted overnight as there is confidence that some strong storms are likely. The Twin Cities could see isolated storms beginning to pop later Wednesday afternoon and spread southeastward.

Better chances of rain Thursday night

Friday rain possible
Any Thursday night storms should end by around sunrise on Friday. Later Friday, however, the heating of the day could whip up another batch.
Dry Saturday
Saturday is likely to be the better day for outdoor activities this coming weekend without having to keep your eyes to the sky. Expect dry skies and seasonable temperatures.
Maybe showery on Sunday
Scattered showers and storms might come our way on Sunday. Any periods of rainfall this droughty summer should be welcome, even if they are scattered.
