A quick shot of arctic air but an impressive one to say the least! High pressure of 1036mb was moving into western Minnesota late this afternoon with cold air advection still occurring east of this high over parts of the Northland late today.
*Tonight will be a frigid one! Lows in the single digits above to single digits below zero with teens below likely in the typical cold spots. Clear to partly cloudy skies with lingering snow showers along the South Shore of Lake Superior and also in far northern Minnesota downwind of Lake of the Woods, Rainy Lake and Lake Kabetogama.
*Warm air advection pattern gets underway on Friday as arctic high pressure moves off to the east with low level winds switching to the south. Could see some light snow develop at times over parts of the Northland mainly from Friday afternoon into Saturday. Snowfall looks to range from a dusting to around 2 inches with the higher totals probably confined to the North Shore of Lake Superior where some lake effect/enhanced snow is possible Friday through Saturday morning.
Highs on Friday will be in the upper teens to lower 20s; Highs Saturday in the upper 20s to lower 30s.
