Very pleasant weather across the Northland through early next week

A brief cool down is on the way for Thursday and Friday (highs in the 60s and 70s) with overnight lows falling into the 40s in some parts of the Northland (fall is coming!) But after that will see temperatures warm back up again, but nothing too extreme in terms of heat and humidity, overall just a real pleasant stretch of summer weather across the Northland!

Remember, for every fog we see in August, that leads to a snowfall this coming winter according to weather lore.

Here’s the 10 day temperature forecast for Duluth, Minnesota.

80s look to return this weekend into at least early next week.

38 days so far this summer (since June 1) with a high of at least 80 in Duluth. Normal for a summer is 23 days at or above 80.

Note: Normal highs in Duluth from August 12 to August 21 are in the mid 70s, with normal lows in the mid 50s.


A series of cold fronts on the move this week, 3 of them to be exact (blue lines on map below)

The final cold front of the 3 moves through the Northland tonight with a cool air mass moving over the area for Thursday.
