Weather Summary for northeast Minnesota and northwest Wisconsin

A wintry day for some, a sloppy/rainy day closer to Lake Superior.  Low pressure was centered along the Wisconsin-Illinois state line late this afternoon while a trough stretched northwest of that low into east central Minnesota.

Widespread wet snow fell today in northeast Minnesota and northwest Wisconsin with marginally cold temperatures aloft and even more marginal surface temperatures to support snow.

Near Lake Superior, wet snow earlier in the morning switched over to rain as the wind blowing off Lake Superior brought in enough low level warm air causing the snow to change to rain, this even as the temperatures aloft were cold enough to keep the precipitation falling as snow, but the surface temperature was the difference in determining the precipitation types today closer to the lake.

Highs today were in the 30s which is near to slightly above average for late November.  Winds were out of the north or east at 5 to 15 mph.

Forecast Discussion for northeast Minnesota and northwest Wisconsin

.Short Term Forecast...

Tonight (November 23)

Mostly cloudy skies should linger tonight with abundant moisture left in place behind the system that gave the Northland snow or rain today.  There could be some areas of fog and possibly even patchy drizzle/freezing drizzle tonight.  Snow showers or mixed precipitation should come to an end this evening in northeast Minnesota and northwest Wisconsin.  Low temperatures will be in the 20s to lower 30s with teens possible in far northern Minnesota.  Winds will be out of the north or northwest at 10 to 15 mph.

Thanksgiving (November 24)

Mostly cloudy skies are expected to persist on Thursday.  Could be a few snow or rain showers around the area as well thanks to a lingering surface trough nearby.  No significant travel impacts are expected though.  Highs on Thursday will be in the 30s, lows Thursday night in the upper 20s to lower 30s.  Variable wind direction at 5 to 15 mph.

.Extended Forecast...

Friday and Saturday (November 25-26)

Things aren't looking very promising for a lot of sunshine the next few days.  Moisture trapped in the atmosphere, not a lot of mixing going on, plus a low sun angle at this time of year could be enough to keep skies generally overcast Friday into Saturday.  Daytime highs will remain in the 30s which is near to slightly warmer than average for late November, but the Overnight lows will be well above average in the 20s and 30s.  Note:  The normal low temperature in late November is in the low to mid teens at International Falls and Duluth.
