Were getting into Fall Foliage season here in the Upper Midwest. Typically fall colors will peak in mid to late September in extreme Northern Minnesota. Mid September to early October along the North Shore and over much of Northern Minnesota. Have to wait until late September/early October for peak conditions here in Duluth/Superior. Southern Minnesota’s peak season is usually late September to mid October. (Source, MNDNR)

Skies were partly to mostly cloudy Today and winds were out of the north or west at 10 to 20 mph.
Forecast Discussion for NE Minnesota and NW Wisconsin
Short Term Forecast – Confidence: High.
Tonight (September 12)
Clear to partly cloudy skies are expected Tonight as high pressure settles into the Upper Midwest. It’s gonna be a cool one as low temperatures bottom out in the 30s and 40s with some 20s possible over the Iron Range and Arrowhead. Frost and freeze headlines are in effect Tonight north of the Twin Ports and away from Lake Superior. Winds will be out of the north or west at 5 to 15 mph.
Friday and Friday Night (September 13)
The weather stays quiet this period as high pressure begins to move off to the east. Sunny to partly cloudy skies for Friday with highs in the 60s to lower 70s with 50s along the North Shore of Lake Superior. Lows Friday Night will be in the 40s, with a few 30s possible. Expect clear to partly cloudy skies Tomorrow Night. Winds during this period will be out of the south at 5 to 15 mph.
Extended Forecast – Confidence: High.
Saturday through Monday (September 14-16)
Temperatures warm a bit on Saturday as SW winds strengthen ahead of an approaching cold front. High temperatures will be in the 60s and 70s. There could be some rain showers either from the cold front moving in from the NW or from a disturbance which will track out of the Western High Plains, if there is any rain in the Northland it should hold off until late Saturday Afternoon/Night the way it looks now. Dries out once again for Sunday and Monday with highs in the 50s and 60s on Sunday, mainly 60s on Monday. Lows Saturday Night will be in the 40s and 50s. Lows Sunday Night will be in the 30s and 40s.
Long Range Forecast – Confidence: High.
Still looking at a chance for some rain during the middle of next week (17th-18th) Late next week could find another push of cool Canadian air making it’s way into the Northland – this is somewhat of a change from what the models were showing 24 hours ago. The West coast trough could still happen but is now delayed until sometime next weekend (21st-22nd) if it happens at all. Stay tuned! Note: I think the transition from summer to fall has begun, and the computer models are feeling the effects. Temperatures through this period are forecast to be near seasonal averages in NE Minnesota and NW Wisconsin.
