Monday Evening Update

Good evening, everyone. Another big temperature swing will lead to more winter weather rolling in here on Wednesday. This is a setup that can throw down accumulating snow into much of the region, with additional snow makers lurking this weekend into next week.

Let’s focus this update on the Wednesday-Thursday setup. It’s a cold front working through here as a wave of low pressure develops along the boundary. Rain along and ahead of the front changes to a mix and snow behind it as temps crash.

Where that marriage of the cold and deeper moisture happens is still in dispute with slight differences showing up on the models.

The NAM likes that hookup in the west then rolling east. You can also see the arctic front with some more showing up behind that by Thursday night…

Here’s the NAM snow map through Thursday morning…

You can see the better snows across the east because they get the moisture from the wave of low pressure. The GFS isn’t quite as snowy as the NAM, but also has better stuff in the east…

The European Model has a similar theme across central and eastern Kentucky…

The new version of the GFS continues to be on steroids with the precipitation amounts with this setup…

Again, that model has no friends at the moment.

The WPC has the eastern half of Kentucky in the slight risk area for 4″+ snows out of this…

Let’s see how the evening models shape up. I’ll share those later tonight. Enjoy the evening and take care.
