October chill ahead; heavy rain potential by Sunday night

Widespread frost next week?

We’re coming up for air across the Upper Midwest. Tuesday night’s storms left a trail of destruction across southeast Minnesota and Wisconsin.

Much of Minnesota enjoys a sunny but cooler respite. Temperatures run as much as 15 degrees cooler than Tuesday highs in the low 80s.

We warm up again Sunday and Monday before the bottom drops out next week.
