UPDATE

Issued at 208 AM EST Mon Jan 26 2026

After collaboration with neighboring WFOs, upgraded the extreme cold watch across southwest Virginia and the East Tennessee mountain zones and southwest North Carolina to a cold advisory for tonight into Tuesday morning. The crests of the ridges and mountains in northeastern Tennessee and southwestern Virginia may reach apparent temperatures as cold as -15F below. With significant ice accretion from the weekend in portions of the region, take the necessary precautions to keep yourself and your pets warm this week!

DISCUSSION

Issued at 1240 AM EST Mon Jan 26 2026

Current analysis shows that the cold front has moved through the region and winds have shifted to the northwest for most of the Valley. Light precip can be seen on radar from Knoxville northward with colder temps starting to move into the region from the northwest. Little to no precip is being reported to the west in the cold, dry air mass over Middle Tennessee. There are some stronger returns on radar over Southeast Kentucky with light snow reported. The drizzle will move out as the cold air moves into the region. A SPS is out for black ice potential for spots that freeze before drying out tonight through morning. Mesoanalysis shows that 850 mb temps are below freezing across the region. Some flurries or possibly a brief light snow will be possible as the cold air first moves in around midnight. The best potential will be Southwest Virginia but any new accumulation will be less than one inch and new ice accumulation potential is ending.

The High Wind Warning in the mountains has ended since the winds have shifted after frontal passage. Winds will remain around 10 mph for the next few hours as the very cold air moves into the region, hopefully helping dry out roadways.

A Cold Weather Advisory is in place for tonight through the morning as very cold air moves into the region after midnight. Wind chills will be in the single digits by morning in the Valley. Wind chills will be below zero in the higher elevations of the mountains. Today will be cold with highs in the 20s in the Tennessee Valley with wind chills in the teens. The higher elevations will have wind chills in the single digits and below zero today.

Tonight through Tuesday morning will be even colder. A Cold Weather Advisory is in place for most of the region and an Extreme Cold Watch is in place for the East Tennessee Mountains and Southwest Virginia. Lows will be in the single digits tonight through Tuesday morning with colder wind chills possible.

This week will generally be cold and dry as a deep trough remains over the Eastern U.S. A few waves moving through the pattern may kick off some light snow or flurries at times but even if that happens it looks brief and uneventful at this time with a dry air mass in place. Highs will be in the 30s for the Valley from Tuesday on. Lows will be in the teens each night starting Tuesday night likely through the weekend.

AVIATION

(12Z TAFS) Issued at 643 AM EST Mon Jan 26 2026

Light ongoing snow flurries across the TN valley this morning are not expected to pose any VIS threats. Flurries may be off/on much of today, have TEMPOs in for current radar trends, skies scattering and clearing this afternoon will end precipitation and return CIGs to VFR. Few gusty winds around, otherwise a steady breeze before winds weaken late.
