Some in East Tennessee will see snow tonight

Saturday Evening Update:

Major changes are on the way to East Tennessee with much colder air returning to the area Friday and sticking around through much of next week.  We see another shot at winter weather arriving Saturday late afternoon/evening that will likely bring scattered snow showers across much of our area.

What we know:

  • Freeze expected for most again overnight into Sunday morning
  • Best chance for accumulating snow will be overnight into Sunday a.m. for areas south of I-40
  • Accumulations will mainly be light and travel issues look to be minor

This forecast model indicates that the best opportunity for light snow will come overnight and remain mainly south of the I-40 area, which is what we agree with as well.

 

 

Another reason we feel as though this won’t cause significant accumulations is that the system is moving rather quickly. In fact, most of the snow should be out of our area by sunrise on Sunday.

 

 

And anther bit of good news is that most areas will see sunshine by Sunday afternoon and temperatures will warm into the 40s and 50s helping to melt most of the snow that does fall, with the exception of the higher elevation of the Smokies.

 

So in summary, here is what we are thinking for snowfall totals from overnight Saturday into early Sunday morning (see map below).

  • Areas well North of Interstate 40 (including areas along the TN/KY border) won’t see any snow
  • Areas South of Interstate 40 (especially the Southern Valley) could see from around a Trace (or dusting) to possibly as high as 2″ in some isolated areas
  • Elevations between 1,000-2,000 feet towards the Mountains (Foothills locations) could see 1″-2″
  • Elevations above 3,000 feet could see 2″-4″ or possibly more towards the higher peaks (Mt. LeConte, Clingman’s Dome).
