Weather Synopsis

Seeing some changes in our weather today as a cold front pushes slowly south through northern Minnesota.  This front has helped to develop some showers and thunderstorms this afternoon in parts of northeast Minnesota -- As of 5 PM, storms were lined up generally from Grand Rapids to between Two Harbors and Silver Bay with movement to the southeast.  Heavy downpours and occasional lightning have been the main threats from these storms this afternoon.  Otherwise today featured partly to mostly cloudy skies across the Northland with highs ranging from the 70s to lower 80s with the warmest temperatures south of Highway 2 in northeast Minnesota and over all of northwest Wisconsin...These areas saw a bit more sun compared to areas farther north.

Through Thursday:  A frontal boundary over northern Minnesota won't clear the Northland to the south/east until Thursday afternoon -- An area of low pressure is set to move east across the northern Plains and upper Midwest through Thursday morning, this low will then exit to the east by late Thursday afternoon.  The front and surface low will produce some lift in the atmosphere, this combined with a weak to moderately unstable atmosphere will continue to generate scattered showers and some thunderstorms in northeast Minnesota and northwest Wisconsin from tonight through Thursday.  Heavy downpours and occasional lightning will be the main hazards out of this activity.  Gusty winds to 30 mph and small hail generally around pea size is also possible in the strongest storms.

Lows tonight will be in the 50s to lower 60s.  Highs Wednesday in the 70s to lower 80s.  Cooler temperatures Thursday with highs ranging from the upper 50s to upper 60s.

Note:  Still keeping an eye on where an upper level low develops for this weekend but the trends in the computer models have been for less and less shower activity in northeast Minnesota and northwest Wisconsin for Friday, Saturday and Sunday.  Still can't rule out a few showers especially on Friday but Saturday and Sunday look mainly dry in most of the area.  High temps don't look too bad with daytime highs in the upper 60s to middle 70s Friday through Sunday.
