Good afternoon, folks. With calmer weather in store for the weekend, it’s all eyes on the potential for a big winter storm to impact the Ohio Valley next week. This looks like a system loaded with all kinds of nasty winter weather with every precipitation type on the table.

Before we get to that, let’s talk briefly about the cold of this morning. It. Was. Brutal. Check out the top 10 coldest readings from the Kentucky Mesonet…

Temps won’t be as cold tonight or Sunday as clouds increase ahead of a weak clipper passing to our north. This may get close enough to cause a few snow showers or flurries to get into northern and northeastern Kentucky Sunday night.

The setup beyond this has been well advertised here on KWC. The mega temp gradient I’ve been showing is one that will lead to a widespread major overrunning winter storm for a lot of the country. What impact it has on Kentucky remains to be seen but rain, sleet, freezing rain and snow are all on the table. Which one of them will be the dominant precipitation type will be the focus of the forecast going forward.

One thing to keep in mind, arctic air is usually underplayed by the models and these setups usually wind up a little farther south and east. Now, that’s what history suggests, but each setup is different.

The Canadian Model shows rain to mainly freezing rain and some sleet. Here’s the model for late Wednesday night and Thursday…

The model then goes straight ugly late Thursday into early Friday…

Again, the model forecasts are just that… Forecasts. They’re not meant to be taken verbatim. Of course, you guys already know this and know they’re only being shown so we can watch trends over the coming days.

No one wants any part of the Canadian Ice…

The EURO has a colder look, but it’s absolutely loaded for bear with winter weather. Here’s the Thursday look from the latest run…

And the look for Thursday night and early Friday…

The freezing rain forecast from this run…

And the snow forecast shows just how far reaching this system may be…

Image

The GFS is the GFS and changes radically from run to run. The model doesn’t really perform very well with extreme setups so it’s really hard to use sometimes. I mean, just a few days ago the model had the east coast blizzard being a total miss. Here’s the ice output from the current run…

Image

If we go to the UKMET, we find it showing much more of a colder scenario with the Thursday system. Here’s the snow map…

Again, model forecasts are NOT to be taken as the gospel from any time range. Trends, folks. Trends!! Let’s hope this turns out as an all rain event or an all snow event. We want no part of anything else.

Enjoy the rest of your day and take care.
