Major warming trend: From furnace to AC in a week?

Freeze warnings again Monday night. 70s and 80s into Minnesota next week. With tropical humidity.

Get ready for some big weather changes in the next week across Minnesota.

Our weather goes from freezing to lake weather in the next week. Our warming trend is gradual this week. But then forecast models insist on a gush of warmer, and more humid air blowing into Minnesota.

First, one more freeze for much of Minnesota. The Twin Cities escaped widespread frost as a cloud deck held temperatures up to 39 degrees at MSP Airport this morning. We may not be so lucky tonight.

Freeze warnings are in effect once again for the blue zones below.

Lows tumble into the teens in northern Minnesota. Temperatures hover around freezing in the Twin Cities Tuesday morning.

The only hope for preventing a widespread freeze in the Twin Cities are the shorter nights now.

It’s possible we may challenge some record lows Tuesday morning across Minnesota. The record low at MSP Airport Tuesday morning is 28 degrees.

Summery next week

All major forecast models insist the warmest air mass of 2020 so far will blow into Minnesota next week. The only differences center on how warm. Models have been cranking out highs in the 70s and 80s, with a few approaching 90 degrees in southern Minnesota next week.
