Tuesday Evening Update

Good evening, folks. We are tracking some light snow across the region, on the leading edge of arctic air pushing in here tonight. This is just the beginning of a stretch of bitterly cold temps taking up residence in our region through the state of the new year.

Let’s begin with the light snow action working across the northern half of the state. We set you up for this a few days ago, and it can put down some light accumulations. We will need to keep a close eye on roads in the north, as they could briefly become fluff covered.

Here are your tracking toys…

Temps tank tonight with single digits showing up across the north, with low and middle teens elsewhere. Wind chill temps go below zero at times in some areas.

Highs Wednesday stay in the teens in the north with low and middle 20s south. Gusty winds make it feel even colder. Lows by Thursday morning drop back into the upper single digits and low teens.

From there, the forecast gets a lot colder, but how we get there is the issue. Snow is likely to fall this weekend, but I’m still not ready to commit to how it comes at us, or how much may fall.

The European Model continues to say we get an arctic front with a wave of low pressure along it Friday night and Saturday…

That blows up into a major storm across the northeast.

The GFS continues to show a different setup and it starts with a system before that one. The GFS has a little better system showing up Thursday night and early Friday…

The model then is MUCH weaker with the system diving in Friday night and Saturday, producing a swath of light snow across our region…

It still develops another system working in from the southwest for New Year’s Eve and Day…

That setup could be a healthy snow maker for us.

The JMA is actually on the side of the GFS this go around, and actually has a much more threatening look…

With our Christmas snow, it was siding with the European Model.

Several of the individual members of the GFS Ensembles are supportive of that idea…

Enjoy your evening and take care.

Tuesday Afternoon Thoughts

Good afternoon, gang. Some light snow and flurries continue to push across he region today, in what is likely just a preview of what’s to come. It’s an extreme winter pattern taking shape for much of the country, with the exact impacts on our weather still being ironed out.

One thing is for sure… This pattern is frigid and will be the coldest extended period since the winter of 2013/14. It might be a good time to winter proof those pipes. 😉

Today’s flakes come at us in streaks from west to east…

Some very light accumulations are possible in a few areas.

Arctic air settles in overnight, with single digit lows showing up across northern Kentucky and teens everywhere else. Highs on Wednesday may not get out of the teens in the north…

The late week light snow potential continues to largely be a small event, with the main chance across the east on Friday…

You can already see the next streak of light snow diving in from the northwest. That arrives by Friday night on the GFS…

The model continues to take the next system and turn it into a snowstorm as we close out 2017 and welcome 2018…

Here’s the animation of all that…

The GFS has that snow system moving in with temps in the teens.

We also find the GFS continuing to go crazy with the cold, showing multiple days of below zero temps next week…

The Canadian Model places more emphasis on the snow system diving in here on Saturday, blowing it up into a nice snow maker. It then turns things so cold, it suppresses the next system…

The Canadian goes absolutely nuts with the cold…

It is also showing multiple days with temps going below zero.

My take:

  • Bitterly cold temps are very likely through next week. There is an increased threat for temps to go below zero on, at least, one occasion.
  • This will likely become the longest period of bitter cold we’ve had since 2013/1014.
  • Wind chills have a chance to get into the danger category at some point.
  • It’s likely we will put some snow on the ground this weekend. It’s too early to tell how much we can get. That all depends on if we can get the southern stream involved.

I will have updates on WKYT-TV starting at 4pm and will throw out another update later on.

Make it a great afternoon and take care.
