Classic October weekend

What makes a classic mid-October weekend in Minnesota? A little frost. Crisp mornings and milder afternoons. That’s the setup this weekend across Minnesota.

I’ve detailed Saturday morning’s widespread frost and freeze warnings in my earlier post Friday. Temperatures recover Saturday afternoon into the 50s to low 60s.

Sunday brings the milder afternoon this weekend. Highs should kiss 70 degrees in southwest Minnesota, with most of us in the 60s.

Cold front late next week

Wednesday brings a chance of rain to southern Minnesota. Then a cold front drives another shot of colder Canadian air south late next week.

Highs will hover in the 40s and 50s late next week.

Overnight lows will dip into the 30s once again across most of Minnesota by late next week.

The American GFS model hints at a possible storm the weekend of Halloween. Right now it suggests mostly rain, with snow possible up north. Hmmm.

Stay tuned.
