Wet weather is likely at times this weekend.
-A cold front will be moving ESE across the Northland Friday evening through the day Saturday. Moisture, lift, and some instability will be present along and ahead of this front on Friday with scattered showers and thunderstorms developing across north-central Minnesota late Friday afternoon or Friday evening, with chances for showers and a few thunderstorms increasing farther south/east into northeast Minnesota and northwest Wisconsin late Friday night through Saturday.
-The potential for severe thunderstorms remains very low with this front on Friday, but locally heavy rainfall is possible as there will be abundant moisture in place consisting of precipitable water values of 1.50″ to around 2.00″!
The setup this weekend, particularly in the Saturday night to Sunday time frame will resemble a setup we sometimes see in winter where we have a low-pressure system taking shape south of the Northland while high pressure sets up to the north across central Canada — The potential for a higher impact heavy rain/flash flood event is there Saturday and Sunday, especially from south-central Minnesota into central and northern Wisconsin as multiple rounds of rain and thunderstorms are expected in those areas.
Here in northeast Minnesota and northwest Wisconsin it does look like will get some more showers at times Saturday night and Sunday, but the heavier rain looks to be more focused farther to the south.
Sunday does have a chance to be a cool late summer day, however, with highs only in the 50s and 60s in the Northland.

NAM 3km model simulated radar forecast valid 1 PM Friday to 7 PM Saturday.
Another brief spike in temperatures is likely Friday with highs ranging from the mid 80s to low 90s in northeast Minnesota and northwest Wisconsin, but this will be short lived once again as a cooler air mass moves in this weekend before temperatures rebound back toward normal early next week.
To go along with the warmer temps on Friday, humidity will increase just a bit with dew point temperatures climbing into the upper 50s to middle 60s in northeast Minnesota and northwest Wisconsin.
