Significant river flooding is possible over the next several days in portions of western and central Wisconsin, far southeast Minnesota and far northeast Iowa.  Source:

There has been a noticeable southward shift in the storm track for late next week.  With this potential storm still several days away, we could see the storm track creep back toward the north again, but for now it appears that the bulk of the significant snowfall would stay south of the Northland late next week.  Stay tuned.

Weather Synopsis for northeast Minnesota and northwest Wisconsin

Another unseasonably mild day as high temperatures climbed into the upper 40s to middle 50s, this despite a fair amount of cold air advection behind Friday evening's cold frontal passage.  850mb temperatures this afternoon ranged from +4 to +6 C, a good 10 degrees cooler than Friday.  Sunshine earlier in the day gave way to widespread mid to high level cloudiness this afternoon.  It was a windy start to the day with westerly winds gusting over 25 mph, the wind did diminish somewhat this afternoon.

Partly to mostly cloudy skies through Sunday night.  Potential for some patchy fog late tonight into Sunday morning, and again late Sunday night.  Still mild with lows tonight in the 20s and 30s, highs Sunday in the 40s and 50s with 30s around Lake Superior, lows Sunday night mainly in the 30s.

Changes occur on Monday as low pressure lifts northeast through the northern Plains -- A warm front and cold front attached to this low will sweep through the Northland Monday and Monday night.  An unusually moist airmass will be found ahead of the surface low with PWATS ~1.00" streaming north into our area, this moisture combined with the lift with the approaching low and frontal boundaries will lead to occasional rain across the Northland for Monday and Monday night.  Note:  There will also be some elevated instability over parts of the area on Monday with CAPE of around 100-300 j/kg, this could cause a few thunderstorms to develop, and if storms do form they will be capable of producing brief heavy downpours and some lightning strikes.

It will remain very mild on Monday with highs in the 40s and 50s with 30s near Lake Superior.  Lows Monday night will mainly be in the 30s.
