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.
