Don't Buy The Bread & Milk Just Yet

Happy Veteran's Day! Thank you for all who have served and are currently serving to protect this great country. Getting into the weather across east TN, many changes are in the forecast for the next 24 hours. We have mostly sunny skies overhead now but cloud cover will increase from our west this afternoon. Showers will likely make a presence by late this evening before transitioning to wintry mix and snow by early Tuesday morning. As you can see below, the transition period will take place around 1am to 3am from west to east. 

As I discussed in yesterdays post, topography plays a huge role in winter time events. The timing of the cold front and ground temperature also play a huge role for this weather maker. For this system, we are breaking down snow accumulations as followed:
Plateau: Up to 1 inch of snowfall
Central Valley: Trace to half an inch (grassy surfaces, vehicles and vegetation primary areas for any accumulation)
Southern Valley: A few tenths of an inch of snowfall possible with the main threat of freezing rain & sleet
Northern TN: Up to 1 inch of snowfall
Foothills/Smokies: 2-3+ inches

Keep in mind very warm temperatures (mid 60's) this afternoon will keep ground surfaces warm into the night. This is good news for morning commuters as most snow will stay off roadways. 

Into tomorrow morning and through the day, I advise using caution in the morning hours. As there will be a rapidly cooling temperatures tonight, patchy black ice will likely form, so slow down and account for some extra time. By mid-morning and through the afternoon, any ice will melt quickly allowing for pleasant road conditions the remainder of the day. 

Don't forget to bundle up tomorrow as high's will only be in the mid 30's (nearly 25 degrees below average). By tomorrow afternoon expect mostly sunny skies to return and carry through the remainder of the work week (gradually warming back up each day). That will conclude todays forecast but be sure to remain weather aware and check back in for the latest details. (@SecretCityWX -Twitter & Facebook)
