Good Monday evening. What a gorgeous day that’s wrapping up out there. I hope you had the chance to enjoy it because Old Man Winter is on the move toward the bluegrass state. Big temperature changes occur as we head into Tuesday. That’s when an arctic front sweeps in.

Check out the temperature difference from one side of this front to the other…

The top image is from the middle of the afternoon with the bottom image from late evening. That’s a heck of a plunge that will be accompanied by gusty winds and showers.

The cold behind that digs in for the end of the week and I have no changed with any of that. The weekend system is still on track to bring the potential for some light snow from Saturday night into Sunday. How much, if any, will have to be fine tuned over the next few days. We are in that famous 4-7 day window where the models fumble around.

Another arctic shot will follow whatever flakes we get and that may set the stage for another storm system trying to sneak under that by the middle and end of next week. The European Model is impressed…
