Wednesday night thunder up north?
A frontal system is likely to trigger scattered thunderstorms across north-central Minnesota Wednesday evening. The Twin Cities could be on the southern end of showers and thunderstorms early Thursday morning.
Here’s NOAA’s HRRR model output Wednesday evening into Thursday morning.
Unseasonably warm through Friday
The upper air pattern across North America keeps warm air over Minnesota through Friday.
Highs in the 80s once again cover much of Minnesota Wednesday and again Friday.
Pattern change next week
A sharp trough of low pressure will dive down across the Upper Midwest next week.
The dip brings a shot of much cooler air into Minnesota starting on Monday. The inbound air mass looks about 20 degrees cooler than today, with highs in the 50s north and low 60s in southern Minnesota by next Tuesday.
Much of northern Minnesota has already seen a few nights of freezing temperatures this month. There may be more frosty nights next week up north.
Right now I don’t think a freeze is likely in the Twin Cities area through at least early October.
Stay tuned.
