A very active weather pattern

Good Saturday and welcome to the weekend. It’s the first weekend of December and the overall weather pattern is starting to look more and more like wintertime. We have a lot of action coming at us in the next several days, with arctic air lurking later next week.

A weak system rolls in here later tonight into Sunday with some light rain. It may be just cold enough for a few wet flakes to mix in early Sunday morning. The best chance is across the north and northeast. The GFS is still seeing the potential:


Sunday just looks like a rather ugly and chilly weather day.

The next system is much bigger and brings heavy rain back in here late Monday into Tuesday…


That could lead to another 1″+ of rain across much of the state.

Arctic air is on the move behind this system, with the traditional timing and evolvement issues showing up with the models. The GFS is too fast and progressive, as always, with that system.

The European Model continues to indicate a wave of low pressure developing along the boundary:


That wave will likely show up stronger on the models in coming days and could deliver a stripe of snow across the region. Behind that, snow showers and flurries will likely fly around through Friday. Highs in the low and mid 20s will be a good bet, but wind chills will make it feel much, much colder.

Overnight low will drop into the low and middle teens, but the Canadian goes even lower:


The pattern from there can throw some additional winter weather makers our way. The morning run of the GFS went a little crazy:
