The Star Tribune's Paul Douglas says it's time to retire the shorts and drag out the jackets because cooler temperatures are here to stay (until a little warm-up near Halloween).
Cold, heavy rain is expected to begin Monday and continue through Tuesday, which will help ease drought conditions a little, Douglas says.
KSTP predicts the downpour will begin Monday evening (WCCO aims for 5 p.m.), producing about an inch of rain in the Twin Cities and up to 2 inches in western Minnesota. KARE 11 is in the same ballpark, predicting 1-2 inches for the metro.
The first frost could happen as early as Thursday, but many forecasters say it's a sure thing this weekend, when it will really feel like fall. WCCO expects highs in the 40s and lows in the 30s.
Snow showers could happen in northeast Minnesota on Thursday, the Duluth News Tribune reports.
Another blast of snow is expected Monday night into Tuesday morning in the already-buried Black Hills of western South Dakota.
