Arctic cold on Monday

Single digit daytime highs are expected Monday in northern Minnesota, with lower teens in the south. Our Monday high in the Twin Cities will happen before 1 a.m. (somewhere in the mid to upper 20s) then we’ll see falling temps. Our daylight-hour high will probably be in the low teens in the metro area. Wind chills will be well below zero on Monday.

The rest of the week? 

Our average Twin Cities high temp is in the lower 30s this time of year. Twin Cities metro area highs are projected to be in the lower 20s Tuesday, then around 30 degrees on Wednesday, followed by around 40 Thursday and mid 30s on Friday. We could see a bit of light snow on Tuesday, and a few light rain showers or snow showers on Friday.

Mild mid-December

The NWS Climate Prediction Center is showing a tendency for above normal temps in the Upper Midwest for Dec. 13 through Dec. 19:
