Good Monday, folks. We continue to track a major Ohio Valley winter storm that impacts our weather from late Tuesday through Thursday. This will bring some wild weather to our part of the world. If you want it in the forecast, there’s a good chance you will find it with this storm.

The storm develops across the Lower Mississippi Valley on Tuesday and rides right on top of Kentucky on Wednesday. It will be strengthening as it does so and that will lead to some wicked weather swings in just a matter of a few hours.

Here’s a rough breakdown to set the stage:

  • Heavy rain and thunderstorms increase from southwest to northeast Tuesday night into Wednesday.
  • Some areas could pick up 1″-3″ of rain during this time. High water issues are possible.
  • Temps may hit 60 in central and eastern Kentucky ahead of the low on Wednesday.
  • Much colder air wraps in quickly from the west Wednesday afternoon and evening. That will lead to rain changing to snow.
  • Wraparound snows will be likely Wednesday night and Thursday. A few inches of snow look very possible.
  • High winds will be a big player through Thursday. 40mph-50mph gusts could cause problems.

You can see all this play out on the models…

The GFS and Canadian Models show some impressive rain totals…

You can actually see a little downsloping in the rainfall numbers across southeastern Kentucky.

As winds become northwesterly Wednesday night and Thursday, we see more of an upslope flow developing. Combine that with a decent wraparound band of snow, and you get the GFS showing some accumulations…

As I said… this is going to bring a lot of different weather to our part of the world, in a short period of time.

Yes, this is an Ohio Valley winter storm, but that doesn’t mean it brings you a snowstorm. For that to happen, you will need that low to head a few hundred miles farther east than is currently forecast. That seems like a very small possibility, at this point. But, this is a HIGH impact storm for our part of the world.

I will have updates later today. Enjoy your Monday and take care.
