A cool weather pattern will cover the entire Northland tonight thru Friday, this will be followed by milder temperatures this weekend. Note: Areas of frost are possible in much of the Northland tonight, Thursday night and Friday night, with Thursday night and Friday night holding the greatest chances for a widespread frost over almost all of the Northland.
Highs were about 25 degrees colder today compared to yesterday in Duluth, and will be about 10-15 degrees colder on Thursday compared to Wednesday’s high temperature in Duluth, so yes we’re going the wrong way in the temperature department. High of 83 on Tuesday, 57 today, and around 40-45 on Thursday. A gusty NE wind will also occur in the Twin Ports Thursday and Friday with wind gusts of 20-30 mph likely on Thursday, and around 15-25 mph on Friday.
Will see milder temperatures return to the entire Northland this weekend with highs in the 60s, and possibly even a few 70s if we get enough sunshine. Could see a few scattered showers in the Sunday-Monday time frame as a cold front moves into the upper Midwest, but an all day rain event is not expected this weekend or on Monday the way it looks now.
Lots of cold air over central Canada today with the southern fringes of this cold air mass affecting the Northland through Friday.
Goes-16 water vapor loop from Wednesday, May 26, 2021 shows a pretty strong system moving east across the Rockies today, this system will move across the Plains on Thursday with widespread rain on the cold side of this system and severe weather farther south in the warmer and more unstable air.
A dry May continues in the Northland – Rainfall departures for May 2021 (thru 4 PM on the 26th)
Brainerd: -2.45″ below normal
International Falls: -1.85″ below normal
Hibbing: -1.54″ below normal
Duluth: -1.30″ below normal

Rain shield associated with Thursday’s system still looks like it will stay mostly south of the Northland, but far southern areas roughly along and south of a line from Pine River and Brainerd east to Hinckley to Hayward could get a little rain at times on Thursday, but the heavier rainfall is expected to stay farther to the south.
