Good evening, folks. The arctic air is diving into the region from the northwest and will take control of our pattern over the next few days.

The short term models are coming in brutally cold for the Ohio Valley tonight. They seem to be picking up on the snowpack and how that influences the temps downstream. The RAP shows a lot of single digits across the northern half of the state…

The HRRR is equally as cold…

And those wind chills…

Wow! Here’s hoping that’s an extreme solution, but these models have the highest resolution of the bunch.

The weekend system throws moisture our way late Friday and that could be in the form of a wintry mix…

One thing to watch for is a frozen ground. Even if temps are a little above freezing, I’ve seen similar situations result in some icy roads.

The temps rise all night Friday into Saturday and should hit the low 60s. Thunder and lightning will be possible before the arctic air moves back in. The end result is a rapid switch to sleet, freezing rain and some snow into early Sunday…

I leave you with the regional radar to track some snowflakes ahead of the arctic front…

Enjoy the evening and take care.
