The National Weather Service has issued a freezing fog advisory for most of Minnesota from late Saturday night through Sunday morning.
Central and western Minnesota are most at risk for icing as temperatures there could fall into the 20s.
The possibility of icing on roads means driving conditions could be treacherous. The weather service urges drivers to slow down, use headlights and leave several car lengths ahead of them in order to increase stopping room.
Temperatures will warm up again Sunday to unseasonable highs. The Twin Cities could hit 49 Sunday, and 54 Monday, WCCO says, with more wintry weather returning toward the end of the week. It could be in the 40s even in the Northland Sunday, the Duluth News Tribune says.
Is it ever going to really snow? There were a flurry of guesses in the The Star Tribune's first round of Guess the Snowfall for the winter of 2012-13.
