Good afternoon, everyone. A Cold Weather Advisory is out for parts of Kentucky tonight and early Tuesday. Wind chills drop to below zero as the Northern Lights try to make an appearance here in Kentucky.

That’s what you guys are here for, right? There’s nothing else you could possibly be stopping by for. No? Ok, I’ll get to that in just a bit.

There’s a chance to see the Northern Lights with the naked eye tonight with a better chance to see them through a camera…

Wind chills will be brutal, so happy viewing!

I continue to watch a light snow and mix maker rolling in here for Wednesday and early Thursday. Some light accumulations are possible from this…

Ok, let’s get to the increasing chance for a winter storm hit this weekend. Here you go with some updates thoughts:

  • It’s becoming apparent this will be a major winter storm for much of the country.
  • The exact location of this wide-reaching winter storm is still a work in progress.
  • Looking at this, I think we get two actual storm systems.
  • The first lead low likely rides into the southern Appalachian Mountains before the big daddy low takes over right behind it.
  • If this is indeed the setup, look out. Significant snow and ice accumulations would show up from Friday night through Sunday.
  • How much and exact details are a ways away from being known as that will all depend on the exact track of each low.
  • The movement, timing and spatial orientation of the brutally cold air across the northern half of the country will be the determining factor in how much winter weather we get.
  • If you want snow around here, you don’t want that high to be so fast that it crushes this storm to our south. That is NOT the favored scenario right now.

The Canadian Model is essentially showing what I just outlined. To see that strong of an arctic high pressure showing up at the exact same time as an active subtropical jet stream across the south is wild. Those two together is how legendary winter storms are made.

Here’s the Canadian from Friday through Monday morning…

The UKMET is similar…

The GFS AI doesn’t show precipitation types, but you can see a similar track with the AI showing another potential storm right behind it…

That matches up well with the EURO AI…

The EURO is likely a bit too slow as the bias is to be too slow ejecting energy out of the southwestern part of the country. Still, it has the overall major winter storm look…

A few more updates come your way later today. I’ll also have a few updates on my Meteorologist Chris Bailey Facebook Page

Have a great rest of your MLK Day and take care.
