Good Tuesday, everyone. We have one more March-feeling day before some dramatic changes press into the bluegrass state. These changes will bring arctic air into town, with the increasing threat to put snow on the ground before the week is over.

Before we get to the winter weather part of the program, we still have numerous showers out there today. Another rumble of thunder will also be possible with temps holding between 55-60 for most of the day…

Arctic air then surges in here overnight and early Wednesday. A few snowflakes may be right behind this front as readings drop into the upper 20s and low 30s then hold there all day.

The scenario for the end of the week into the weekend continues to be a little problematic. The late night forecast models are trying to take our Friday/Saturday system back toward the north and west. I will get to that in a moment, because we need to talk about a light snowfall ahead of that for Thursday into Thursday night.

You can see this system showing up on the NAM…

That’s likely a little underdone with the coverage. In looking at this system, there is a good chance for most of the state to get in on a light snowfall during this time. With temps solidly below freezing, some slick roads would develop.

The Canadian Model also shows the Thursday system very well, and is now trying to pull the second storm farther north and west. It actually brushes southeastern Kentucky with additional accumulating snows …

That’s a pretty big jump from the earlier run, and the European Model did the same…

The GFS Parallel is farthest north of them all, bringing snow to much of the state…

This system is just getting into the area to where it can be properly sampled and ingested into the computer models. There is still a lot of time and room for adjustments with this system over the next few days.

Very cold air comes in behind this for the weekend and the Canadian is goingย crazy with the cold…

I doubt the numbers get THAT cold, but it’s giving you an idea of the air mass we are dealing with.

I will have updates later today, so check back. Make it a great Tuesday and take care.
