Some rain at times Thursday night-Saturday; Mild temps continue through early next week

Will finally see a bit of a change in the weather pattern over the next few days as a strong upper level ridge which has been anchored over the upper Midwest the last few days begins to break down thanks to a trough approaching from the Northern Rockies – That trough combined with a warm front and cold front moving across the area late this week will cause rain chances to go up in northeast Minnesota and northwest Wisconsin, especially from late Thursday night through Friday night, but some lingering showers are possible even into Saturday.

Note: Much of the Northland looks to get about a quarter to half inch of rain out of this system for Thursday night-Saturday, but higher amounts up to an inch are possible in spots.

An upper level ridge will remain over our area for one more day on Thursday before we see a trough currently over the Rockies move into the upper Midwest. Moisture is lifting north ahead of the approaching trough from the west today.

Goes-16 water vapor loop from Wednesday, September 29, 2021.

Most of the day Thursday will be dry in northeast Minnesota and northwest Wisconsin, but some rain is possible by Thursday night/Friday morning.

Record warmth in the Northland today – Here are the new record high temps which were set for September 29th.

Brainerd, MN: New record 84; old record high was 83 set in 1905

Hibbing, MN: New record 79; old record 77 set in 2000

Very warm temperatures continued across the region today with widespread 70s and 80s, and even a few 90s once again in parts of northwest Minnesota. Temperatures were a lot cooler, however, near Lake Superior due to a stronger onshore wind today.

Temperatures will continue to be well above normal in the Northland on Thursday with highs in the 70s to lower 80s, but it will be cooler once again closer to Lake Superior.

Record Highs for September 30th

Hibbing, MN: 84 set in 1976
Brainerd, MN: 83 set in 1932
Ashland, WI: 83 set in 1937 and 1976
Duluth, MN: 82 set in 1897
International Falls, MN: 82 set in 1922 and 1989

Note: Thursday will likely be our last real warm day this week, but even after Thursday we’re still looking at above normal high temps, with 60s and perhaps a few 70s from Friday through this weekend, and probably even into early next week. There really are no signs showing up per long range model guidance for widespread frost/freeze conditions in the Northland through most of next week.


Widespread low clouds and fog over western Lake Superior and along the North Shore (yellow outlined area) this morning and early this afternoon has been eroding this afternoon, but low clouds and fog could return tonight into Thursday morning, and some of that fog could become dense.
