DISCUSSION
ISSUED AT 1231 PM EST SUN FEB 1 2026
CLOUD COVER WILL CONTINUE TO DECREASE AS TEMPERATURES ALOFT
MODERATE UNDER A BUILDING MID/UPPER RIDGE. CLEAR AND NEARLY CALM
CONDITIONS TONIGHT WILL RESULT IN LOW TEMPS IN THE SINGLE DIGITS
TO AROUND 10 IN NORTHERN CENTRAL SECTIONS, AND TEENS SOUTH. WITH
THE LIGHT WINDS, WINDH CHILLS WON'T BE MUCH BELOW THOSE VALUES,
EVEN IN THE MOUNTAINS, SO NO ADDITIONAL COLD ADVISORY PRODUCTS
WILL BE ISSUED FOR TONIGHT. A FEW ISOLATED SPOTS IN THE HIGHEST
ELEVATIONS MAY SEE WIND CHILLS AROUND -5 TO -10.
MONDAY WILL BE SUNNY AND WARMER UNDER THE RIDGE ALOFT, WITH
TEMPERATURES TRYING TO BREAK FREEZING AS NORTH AS THE TN AND VA
STATE LINES. THIS WILL HELP IMPROVE TRAVEL CONDITIONS AS ICE AND
SNOW MELT IN SUNNY AREAS, ALTHOUGH SHADED AREAS WILL LIKELY STAY
ICY. TUESDAY WILL BE EVEN WARMER WITH A SURFACE HIGH PRESSURE
LOCATED TO THE EAST, ALLOWING SW FLOW THROUGH THE LOW LEVELS.
A SHORTWAVE APPROACHES THE AREA FROM THE NW, BRINGING A WEAK
FRONT TO THE AREA TUESDAY NIGHT INTO WEDNESDAY. PRECIPITATION
WILL PRIMARILY BE RAIN, BUT LOCATIONS THAT GET TO NEAR OR BELOW
FREEZING WEDNESDAY MORNING MAY HAVE A MIXTURE OF RAIN AND SNOW.
THE HIGHEST ELEVATIONS OF EAST TN AND SW VA MAY SEE SOME LIGHT
ACCUMULATION BEFORE PRECIP ENDS WEDNESDAY EVENING.
TEMPERATURES COOL AGAIN ON THURSDAY BEHIND THAT SYSTEM, WITH DRY
CONDITIONS CONTINUING THROUGH FRIDAY.TEMPERATURES TREND UPWARD AGAIN
FRIDAY, BUT THAT APPEARS SHORT-LIVED AS ANOTHER COLD FRONT WILL
IMPACT THE REGION NEXT WEEKEND.
