Weather Synopsis for northeast Minnesota and northwest Wisconsin

Sunshine was most abundant in far northern Minnesota today, elsewhere it was generally mostly cloudy with a few peeks of sun every now and again.  Cooler temperatures today with highs in the mid 20s to low 30s which is near to still a few degrees above average for late February.

Low pressure (990mb) over southwest Kansas at 4 PM today is forecast to move into northeast Missouri Friday morning, southern Lake Michigan Friday Friday evening, and over Lake Huron by Saturday morning.

Note:  The track of this storm is just too far south to produce a lot of snow here in the Northland, but there will be some snow at times mainly in parts of northwest Wisconsin beginning possibly as early as late tonight but more likely from Friday through early Saturday morning.  The greatest snowfall should remain down around the Park Falls and Phillips areas in northwest Wisconsin with lesser snowfall as you head northwest toward the Hayward area.

Conditions should become somewhat favorable for the development of lake effect snow showers along the South Shore of Lake Superior on Friday with a north/northeast wind off the lake which will then turn to the north/northwest Friday night -- 850mb temperatures are forecast to be at around -12 to -16 C and this should be cold enough to generate some lake effect snow.  Note:  A few of these lake effect snow showers may even affect portions of Superior and mainly on the south side of Duluth during the day Friday but I don't think there will be any snow accumulation here in the Twin Ports.

Low temperatures tonight will be in the teens and 20s with single digits in far northern Minnesota.  Highs on Friday mainly in the 20s.

Looking ahead:  There could be some snow showers or flurries around parts of the Northland Saturday night, possibly lingering into Sunday with a dusting of accumulation possible.

Forecast for Duluth and Superior

.Tonight...  Mostly cloudy.  Low 18 to 23.  Wind north to northeast at 10 to 20 mph.
