.DISCUSSION...
Issued at 135 PM EDT Tue Mar 17 2026

Currently some light isolated snow showers going on across northeast 
Tennessee and southwest Virginia as cold air continues to squeeze 
out moisture from the low level clouds. Expect to see on/off snow 
showers into the afternoon hours, but with more and more sun peaking 
through it's going to be difficult to see additional accumulations 
outside of the mountains. Another cold night with continued cold air 
funneling in at the lower levels will lead to widespread sub-
freezing temperatures and dropping into the teens across southwest 
Virginia. Skies begin to clear out on Wednesday and warmer air 
advects in from the south. 

We'll see a warming trend through the rest of the week as generally 
increasing heights through the mid levels begins to build in. Some 
models try and bring in a weak frontal passage Thursday into Friday 
which doesn't impact temperatures too much, but could bring a quick 
shot of rain to the region. A more pronounced cooldown looks to 
arrive heading into next week dropping temperatures back to near 
normal.
