Colder weather showing up

Good Tuesday, everyone. We are coming off a record-setting warm day across the Bluegrass State, but Old Man Winter is ready to fight back in over the next several days.

Monday in Lexington was the warmest day on record for this late in the year. We hit 74 degrees, and that’s the second-highest temperature ever for the month of December. Only Dec. 2 and 3, 1982, recorded a higher temperature: 75.

Now comes some chillier weather moving in behind a cold front. Gusty showers will start the day as highs stay in the 40s in many areas:

Another system moves in late Wednesday, with chilly showers. Much colder air then moves in Thursday and Friday on a strong northwesterly flow:

That can lead to some snow showers and flurries across the central and eastern parts of our area.

Our New Year’s weekend continues to look wet as the first of two systems moves in from the southwest:

Once we get past that, look out. We might see a harsh winter pattern setting up across our region and for much of the country.

Arctic air is going to move in here by the middle of next week:

The leading edge of that arctic air is likely to find resistance from the southeast ridge being shoved out into the Atlantic. That’s something to look for when highlighting potential winter weather events and storms across the Ohio and Tennessee valleys.

You can clearly see what I’m talking about on the European model, with systems running from southwest to northeast:

A tremendous amount of blocking is showing up in areas that can put the country into the deep freeze. The GFS ensembles for the middle and end of next week get the ball rolling:

Have a great day and take care.
