High temperature forecast for Friday, February 28th, 2020.

Still looks mainly dry in northeast Minnesota and northwest Wisconsin through most of next week. Sorry, no state hockey tournament blizzard in Minnesota this year, speaking of which, when is the last time we actually had a winter storm during that tournament? But all you hear about is well March is coming, time for a tournament blizzard, okay then. Big pet peeve of mind.


…Weather Summary…

Clear to partly cloudy skies will be found in the Northland tonight and Friday.

A cold one tonight with lows falling into the single digits, teens and even some 20s below zero. Highs on Friday will be in the 20s.

Looks generally dry through the weekend with warmer temperatures. Highs on Saturday are forecast to be in the 30s, then on Sunday high temperatures are forecast to range from the mid 30s to mid 40s, with a chance for near 50 degree temperatures in some parts of the Northland, but this will depend on the extent of cloud cover, and timing of a cold front. Less clouds, later cold frontal passage=better chance for temps to climb toward 50 degrees Sunday afternoon.
