Forecast Discussion for northeast Minnesota and northwest Wisconsin

.Short Term Forecast...

Tonight (November 20)

High pressure will remain in control of our weather tonight resulting in mostly cloudy to partly cloudy skies.  Low temperatures will be in the single digits and teens with east or southeast winds at 5 to 15 mph.  Note:  There could be a few lake effect snow showers or flurries later tonight along the North Shore of Lake Superior.

Monday (November 21)

A few flurries are possible especially during the morning along the North Shore of Lake Superior - Otherwise mainly dry on Monday under partly to mostly cloudy skies.  High pressure will be centered to our north/east while low pressure and a trough move into the northern Plains/western high Plains.  Highs on Monday in the 20s to lower 30s with lows Monday night in the teens and 20s.  Winds will be out of the east or southeast at 10 to 15 mph.

.Extended Forecast...

Tuesday and Wednesday (November 22-23)

Snow and possibly some mixed precipitation on the way! Sort of a dual system to deal with for Tuesday and Wednesday with energy in the northern stream and energy with the southern stream, the stronger system will be the one over the central Plains that'll then track toward the east/northeast, passing well to the southeast of our local area.

Looks like a long duration snow event in most of the Northland although a lot of this snow should be on the light side the way it looks now.  Temperatures at the surface will be marginal during this event, likely hovering around the freezing mark especially around Lake Superior, the snow that falls will probably be on the wet side.

Note:  The temperatures aloft during the Tuesday-Wednesday event are expected to remain cold enough to support snow as the main precipitation type throughout the Northland, but milder air flowing off Lake Superior could cause the snow to mix with drizzle/rain especially on Wednesday near the big lake.
