Another very mild day in most of the Northland as highs today topped out in the upper 60s to lower 70s, but a stronger onshore flow (east wind) did keep temperatures a tad cooler closer to Lake Superior where highs reached the upper 50s and lower 60s today which is actually where our highs should be this time of year.
Three upper lows/troughs on the map today.
1: Pacific northwest
2: Eastern Canada/northeast U.S.
3: Southwest U.S.
Goes-16 satellite loop from Monday, September 27, 2021.
Warmer temperatures continue in the Northland on Tuesday with widespread 70s likely for daytime highs, and there’s even a chance that a few locations see their temperatures climb into the lower 80s! Note: Winds will shift to the south on Tuesday so we should see less cooling near Lake Superior.
Although highs will be well above normal on Tuesday, I don’t think will set any new high temperature records in the Northland – See list below.
Here are the record high temperatures for September 28
Brainerd, MN: 89 set in 1956
Ashland, WI: 87 set in 1905
International Falls, MN: 82 set in 2011
Hibbing, MN: 82 set in 2014
Duluth, MN: 81 set in 2014
Check out the temperatures farther to our west where widespread 80s and even some lower 90s are expected on Tuesday over the Dakotas into western and southwest Minnesota.
Late week rain chances
A cold front will be moving east into the upper Midwest late this week. This front could bring some rain to northeast Minnesota and northwest Wisconsin this weekend, especially in the Friday-Saturday time frame the way it looks now.
