21 day until Christmas?? How did that happen? What month is this again?
Some Minnesotans I talk to over the weekend are still stunned that it's actually December. If your seasonal compass is a little off, you're in good company.
The first 3 days of December this year felt more like October. In fact, Monday's high of 55 degrees as the average high for....October 22nd...or April 10th. Take your pick.

So far we're running about +16F vs. average temps at MSP for the first 3 days of December. That's not just "unseasonably warm"...that's like living in a whole different month.
MN Climate Working Group's Greg Spoden sends along this news on just how rare our December 55F temp is for the metro.
Today's maximum temperature in the Twin Cities will reach at least 55 degrees F. Attaining a temperature of 55 degrees or greater during December is rare for the Twin Cities, occurring on only 20 December dates since the modern temperature record began in 1872 (141 years of record).

Wow.
"Average Front" blows in:
It seems even our cold fronts this year are just "average fronts" that return our temps to near average levels after periods of unseasonable warmth.
The cooler air will be with us for most of this week. Temps should stay in the 30s for highs, with the exception of Thursday when November-like 40s will make another push.
As the warmer air pushes back in, some mixed precip may fall Wednesday night into Thursday. It may be mostly warm enough for just plain rain...but temps may be marginally cold enough to produce some freezing drizzle.
Weekend storm trending south?
Monday's model runs showed a distinct trend toward pushing our potential weekend snow system south.
The latest runs push the bulk of heavy snow with the system toward Madison & Chicago.
At this point the GFS & Euro suggest only lighter snow Friday & this weekend for the metro and southern Minnesota.

The models may still flop around some on this one during the week. Expect more changes in the potential storm track and...stay tuned.
