DISCUSSION

Issued at 1227 AM EST Tue Feb 24 2026

Some light snow can be seen on radar this evening in Southwest Virginia and Northeast Tennessee. Recent accumulations reported are very light. HREF one hour snowfall has this snow tapering off shortly after midnight, ending entirely before morning. Lows will be in the upper teens and lower 20s this morning in the Tennessee Valley despite lingering clouds. Wind Chills in the single digits to below zero are expected through Monday night across the higher elevations of the southwest VA, East TN, and southwest NC mountains.

In the upper levels, the deep trough over the East Coast is moving out to sea slowly. Northwest flow will continue as a trough moves into the Northeast on Wednesday. At the surface, high pressure is over the Southeast today. A low is moving into the Great Lakes tonight and Wednesday, leaving a stationary boundary across the region Wednesday through Thursday. The best chance for rain will be Wednesday night through Thursday evening as the boundary lingers. Temps will be warm enough for an all rain event. Although some light snow will be possible in Southwest Virginia and extreme Northeast Tennessee as the boundary first approaches early Wednesday morning but no accumulation is expected.

Strong southwest winds possible Tuesday night and Wednesday especially across the higher elevations. HREF has 850 mb winds increasing Tuesday night peaking in the early morning hours around 50 knots. Winds will become more westerly as the higher winds move in, so downsloping may be minimal. Cloud cover will keep stronger winds from mixing down in the Tennessee Valley, although gusts of 20 to 25 mph still seem possible there. In the higher elevations of the East Tennessee Mountains a Wind Advisory may be issued later on.

The front will finally move through the region Thursday night bringing a drop in dew points Friday but not colder temperatures. The weekend looks dry with nearly zonal flow or weak troughing aloft. Temperatures in the Tennessee Valley will be warmer this weekend with highs mainly in the 60s.

AVIATION

(06Z TAFS) Issued at 1227 AM EST Tue Feb 24 2026

Flurries/light snow showers will end early at TRI along with the better chance for brief MVFR cigs/vsby. Otherwise, a VFR forecast for the period all sites with the low VFR cigs at TYS/TRI dissipating this morning. The winds at 2kft will be strengthening overnight and will likely result in LLWS at CHA and TRI by the end of the period, but at TYS the southwest surface winds are expected to increase enough to keep it from meeting LLWS criteria.
