11/26 - 11am - Happy Thanksgiving!

Happy Thanksgiving from here in Louisville! It's a good ten degrees cooler here in Louisville compared to MSU, so it's definitely time to bundle up! Back in East Mississippi, a Freeze Warning is in effect as temperatures drop below the 32 degree mark early tomorrow.

I just looked at the 850 mb charts from both the NAM and GFS computer models and they agree that we may see some snow and rain showers this afternoon and evening around Louisville. Below freezing temperatures at 850 mb (5000 feet in altitude) usually help in the production of snow when there's enough moisture. Temperatures here at the surface should stay above freezing, so any snow that falls will not stick to the ground.

The long-range GFS has been quite erratic with the imminent cold blast for the Eastern US. Latest indications are pointing to a date of December 3rd for this cold blast to begin, and there may even be a bit of snow as far south as Louisville. It's unclear right now whether or not this cold air will stay around for more than a week, but regardless we're heading into quite a cold pattern around the region.

I hope that everyone has an excellent Thanksgiving. Eat lots of turkey!
