DISCUSSION

Issued at 141 PM EST Sat Feb 21 2026

Two rounds of winter weather expected between tonight and Monday across southwest VA, northeast TN, and the East TN mountains. A Winter Weather Advisory in in effect from midnight tonight through midnight Monday night.

Precipitation spreads into the area tonight along the leading edge of an incoming trough. Rain changes to snow around midnight across the east TN and southwest VA mountains. Then, the rain/snow line moves down in elevation toward sunrise with snow showers/flurries across the lower elevations. The bulk of the precipitation moves east of our area by 10 AM with this first wave. Elevations above 4000 feet across the east TN mountains are expected to see 1 to 3 inches of snow during this time. Lesser amounts of 1 to 2 inches expected between 2500 and 4000 feet. The highest elevations of southwest VA may see 1 to 2 inches. A dusting to a few tenths of an inch of snow are also possible across valley locations across northeast TN and southwest VA. Minor travel impacts are probable across the highest elevations during these times.

We see a brief break in precip Sunday afternoon before the northwest flow snow machine cranks up Sunday night through Monday. An additional 2 to 4 inches of snow is expected during this time above 4000 feet across the East TN mountains and 1 to 2 inches between 2500 and 4000 feet. For southwest VA mountains, another 1 to 2 inches. Minor travel impacts are likely at times across the highest elevations and probable across the low to middle elevations. Accumulations from trace amounts to a few tenths of an inch are possible across the valley locations of southwest VA and into northeast TN. Little to no impacts expected for valley locations.

The two periods of expected winter weather allowed for a long duration Winter Weather headline. The advisory is in effect from midnight tonight until midnight Monday night. This long duration was done in order to simply things, instead of ending an advisory Sunday afternoon and having to reissue a new one for Sunday night.

Additionally, we are still expecting gusty winds areawide Sunday and Monday. The highest peaks of the East TN mountains will gust to around 40 mph at times, and valley locations across the rest of our area will see gusts from 20 to 30 mph. With below normal temperatures in place, and gusty winds, wind Chills in the single digits to below zero are expected Sunday through Monday across the higher elevations of the southwest VA, East TN, and southwest NC mountains.

Snow tapers off Monday night with drier conditions and warming trend expected into the mid-week. Next chances for rain will be Wednesday night into Thursday with it currently looking to trend drier by next weekend.
