KEY MESSAGES

Updated at 1247 AM EST Wed Feb 4 2026

- Patchy to areas of fog early this morning (potentially into midday for snowier locales), locally dense fog is possible. Drive with caution.

- Light rain showers possible today, before transitioning over to snow showers late afternoon and evening for northern portions of Tennessee and especially elevated locations. Light snow accumulations generally a half inch or less in the northern TN valley and SW VA, up to an inch in the East TN Mountains. Black ice of concern Thursday morning, especially in areas with remaining snow.

- Cold frontal passage late Friday, bringing a chance for light rain/snow and a drop in temperatures Friday night/Saturday.

- Pleasant temperatures next week.

DISCUSSION

Issued at 1247 AM EST Wed Feb 4 2026

Much of the region is encased in fog and low clouds right now thanks to rain falling on a still present snowpack. Locally dense fog is possible, so drive with caution this morning. Fog should remain through the early morning hours, and may persist into midday before lifting into low level stratus. The bulk of the rain is done with this event, although a few lingering showers will be around before a changeover to light snow occurs as a cold front pushes through the area today and brings cooler temperatures. Marginal temperatures and light overall precipitation should keep snow fairly limited, and snow showers will taper in areal coverage tonight. Best chance at seeing 1 inch of snow is likely in the higher elevations of Carter and Johnson Counties, but a re-whitening of much of the ground is possible as the snow showers occur even in lower elevations. The other concern as we head into tonight and Thursday morning will be black ice formation as meltwater from the retreating snow and remnant showers freeze as temperatures plunge back into the lower 20s.

On Friday a secondary trough brings a 130 knot upper jet, subsequent dynamics allow for a shot of rain/snow to cross northern TN into Virginia during the PM hours Friday into early Saturday. Temperature profiles at this range look pretty marginal, though some accumulation is possible. Colder higher elevations have the best shot of seeing accumulating snowfall once again.

A little bit more hand fighting in the upper levels before an upper ridge can finally begin to build over the Mississippi Valley early next week, bringing much milder conditions at last to East Tennessee. The higher heights should provide for a consistent thaw for at least the first half of next week.

AVIATION

(06Z TAFS) Issued at 1247 AM EST Wed Feb 4 2026

Unsettled weather with poor aviation conditions are expected to persist through the TAF period. For this morning, predominant IFR cigs are expected, with periods of LIFR possible. Light rain or drizzle will be intermittent, but the combination of past rainfall and snowmelt will allow for persistent reductions in vis, particularly at TRI/TYS. Tomorrow afternoon and evening rain chances will return. CHA will have the greatest probability to return to MVFR cigs. TYS/TRI could see light snow late Wednesday, and are generally expected to remain socked into IFR conditions.
