Lower than average temperatures for the month of October begin to sink in this weekend, bringing frost and most likely snow as early as Monday in the Twin Cites.
After the season's first frost early Sunday morning, cooler air will probably spark snow showers Monday and Tuesday, which could leave a thin coating, the Star Tribune's Paul Douglas predicts.
KSTP also expects some light accumulations by Tuesday, which wouldn't be that unusual. In 2009, 3-4 inches fell in mid-October.
The Pioneer Press says the earliest recorded accumulation of at least 1 inch of snow in the Twin Cities was Sept. 26, 1942.
A mix of rain and snow could stretch out until Wednesday, according the National Weather Service.
Douglas says "next week will feel like a cold slap across the face" as the first hard "killing" freeze comes in the middle of the week.
Before the winter-like weather pushes in, the Twin Cities can expect scattered showers and drizzle Thursday, FOX 9 said. WCCO says the Duluth area might already see wet snowflakes overnight, but no accumulation.
Friday will be cloudy with a few rays of sun poking through. Highs will be around 50 degrees.
