Arctic air and some snow on the way

Good Saturday, folks. It’s a fairly calm weekend, but all that changes as we roll into Monday. That’s when a blast of arctic air invades much of the country, including here in Kentucky. This could threaten a few records and even bring some snow into our part of the world.

Let’s begin with today and roll forward. Highs will be in the 40s after another frigid start in the 20s. Skies will be mainly clear and that continues into the evening for Wildcats fans out at Kroger Field. Dress warm because temps are in the 30s during the game.

Sunday is a better feeling day with readings deep into the 50s. Winds will be gusty as some clouds increase during the afternoon and evening.

here are my updated thoughts on the setup ahead:

  • The arctic front arrives from northwest to southeast on Monday and is likely to have a wave of low pressure along it.
  • Temps ahead of this boundary may touch 60 in the east and southeast early on, with a major crash taking place as the day wears on.
  • Rain develops ahead of the boundary on Monday, but much of the precipitation appears to be behind the front in the cold air.
  • This leads to a band of snow behind our front from Monday afternoon through Monday night.
  • As the system snows work away early Tuesday, a northwest flow should pick up some moisture from Lake Michigan and bring flurries and some snow showers on Tuesday across the central and east.
  • Can we get some accumulations from this? It’s looking more and more like the answer is yes. That will be especially true Monday evening and Monday night.
  • With a rapid temp drop to well below freezing, a decent freeze up will be possible.
  • Temps will be brutal for this time of year Tuesday into Wednesday. Temps on Tuesday may stay mid and upper 20s for highs with wind chills dipping into the single digits. Lows by Wednesday morning may be historic for so early in the season.

As we get closer to this winter blast, the models are in line with the general line of thinking.

Here’s the GFS:

The European Model is just a little slower with the evolution of the system, but it has the same idea:

Enjoy the day and take care.
