The heaviest snowfall amounts tonight are expected to remain north/northeast of Duluth.  I'm thinking will get about 1-2" of snow in the Twin Ports tonight.

Still keeping an eye on next Monday and Tuesday, this is when we could get our next decent snow event in northeast Minnesota and northwest Wisconsin.  Still quite a bit of model disagreement though so stay tuned for new updates over the weekend.

Weather Synopsis:

An area of low pressure has moved into northeast North Dakota this afternoon with strong 12-hour 500mb height falls 90-150 meters covering the northern Plains per mesoanalysis.  A strong thermal gradient is in place for today's clipper with late afternoon 850mb temperatures ranging from +5 C in far southwest Minnesota to -12 C in far northeast Minnesota.  3 PM temperatures ranged from the 50s and lower 60s in central Nebraska to the teens across northern Minnesota.

Partly to mostly cloudy skies this morning across the Northland gave way to mostly cloudy skies this afternoon with some snow affecting portions of the area as low pressure approaches from the northwest.

*Light snow tonight as low pressure tracks from eastern North Dakota to north of Green Bay, Wisconsin by daybreak.  Winds to the north of this low will be out of the east for most of the night, this will result in some lake enhanced snow tonight along the North Shore of Lake Superior.  Lows will range from the single digits below zero in far northern Minnesota with teens in northwest Wisconsin and around Lake Superior.

*Tonight's clipper will head into eastern Canada on Saturday -- Lingering snow showers and flurries are possible early in the morning otherwise expect partly to mostly cloudy skies during the day.  A cold front approaching from the northwest could cause some snow showers Saturday night mainly in northern Minnesota.  Highs on Saturday will be in the teens and 20s.
