Temperatures are much warmer this morning than this time yesterday. In fact, some locations are recording a 20-30 degree swing. Changes are upon us though as a cold front will pivot through the region this evening, providing the foundation for a potential snow event Thursday.
Looking at probabilistic guidance, the odds of at least one inch or more of snow are high from Knoxville and north. As you can see below, half of East Tennessee see's a 50% or greater chance of this opportunity. This is higher than this time yesterday, and I suspect this will continue to grow into tonight and Thursday.
Given the continued confidence, the NWS in Morristown has issued a Winter Storm Watch for the Smokies, Northern Plateau, and counties bordering KY. These locations (highlighted in blue) are expected to see 4-6 inches, with locally higher amounts possible. For the remainder of us, I would not be shocked to see a Winter Weather Advisory for Kingston and up to Kingsport (roughly). This essentially means the central valley and north. These locations will likely see 1-3" with anything south of here (Chattanooga to near Athens) seeing a trace up to an inch. Travel, like with most snowy events, will be impacted. Use caution, have a way to receive alerts, and plan for slow travel times Thursday evening and again Friday morning.
We will continue to update you on the latest as changes continue to be likely. For now, plan for snowfall (in the areas highlighted above) along with very cold Friday temps. Most will struggle to top freezing during the afternoon. More details in our video forecast below:
