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.
