NEAR TERM
(TONIGHT)
ISSUED AT 213 PM CST WED FEB 4 2026
PERSISTENT LOW CLOUDS PREVAILED ACROSS THE TENNESSEE VALLEY IN THE
WAKE OF A COLD FRONT PASSAGE EARLIER IN THE DAY. THE FRONT NOW
EXTENDED FROM FAR WESTERN NORTH CAROLINA, TO NEAR ATLANTA AND
MOBILE. AN EXTENSIVE AREA OF POST FRONTAL CLOUDS CONTINUED OVER
A LARGE AREA WEST OF THE COLD FROM MIDDLE TENNESSEE TO WESTERN
MISSISSIPPI. A VORTICITY MAXIMA ACCOMPANIED BY CLOUDS WAS ALSO
HEADING TO SSE OVER EASTERN ARKANSAS. ALTHOUGH CLOUDS MAY FADE
SOMEWHAT OVER OUR WESTERN AREAS LATE IN THE AFTERNOON TO EARLY
THIS EVENING, AM EXPECTING THEM TO REMAIN ACROSS THE AREA, AND/OR
REDEVELOP, DUE TO THE APPROACHING UPPER SYSTEM AND NIGHT TIME
COOLING.
CURRENT TEMPERATURES ACROSS THE REGION RANGED FROM THE MID 30S TO
AROUND 40 WITH NW WINDS OF 5-15 MPH. STRONG COLD AIR ADVECTION
WILL BECOME MORE DOMINATE AS WE GO INTO THE NIGHT TIME. THUS
TEMPERATURES WILL TUMBLE, WITH LOWS BY DAYBREAK THURSDAY CHILLING
INTO THE LOWER 20S. A N-NW WIND OF 5-10 MPH AND A GOOD 5-10 DEGREE
TEMPERATURE/DEWPOINT SEPARATION SHOULD INHIBIT THE DEVELOPMENT OF
FOG IN THE LATE NIGHT.
SHORT TERM
(THURSDAY THROUGH FRIDAY)
ISSUED AT 1000 AM CST WED FEB 4 2026
DRIER AIR FROM THE NW WILL CONTINUE FILTERING IN, WHICH SHOULD
RESULT IN CLOUDS FINALLY FADING AND MORE DIRECT SUN RETURNING
THURSDAY. DESPITE THE SUN, STRONG COLD AIR ADVECTION WILL HELP
CONTINUE CHILLY CONDITIONS, WITH HIGHS ONLY WARMING MOSTLY INTO
THE LOWER 40S AND NW WINDS OF 5-10 MPH. COLD CONDITIONS CONTINUE
THURSDAY NIGHT WITH LOWS IN THE MID 20S. A NOTICEABLE WARMER TREND
IS EXPECTED FRIDAY. UNDER SUNNY SKIES, HIGHS SHOULD RISE INTO THE
MID TO UPPER 50S.
LONG TERM
(FRIDAY NIGHT THROUGH TUESDAY)
ISSUED AT 955 PM CST TUE FEB 3 2026
THE WARMING TREND CONTINUES THROUGH EARLY NEXT WEEK AS THE
AFOREMENTIONED UPPER LEVEL RIDGE AND SUBSEQUENT SFC HIGH PRESSURE
CONTINUES TO INFLUENCE THE AREA. DRY CONDITIONS ARE FORECAST AS
HIGHS WARM INTO THE 60S BY SUNDAY. THESE TEMPERATURES ARE AROUND
5-10 DEGREES ABOVE NORMAL FOR THIS TIME OF YEAR. THE MAIN FEATURE
IN THE LONG TERM TO MONITOR WILL BE THE TRACK OF A POTENTIAL COLD
FRONT FORECAST TO PUSH SOUTHWARD FROM CANADA INTO THE APPALACHIAN
REGION. IF THIS FRONT SHIFTS MORE SOUTHWARD THAN CURRENTLY
FORECAST, TEMPERATURES WILL BE MUCH COOLER THAN CURRENTLY
EXPECTED. WE WILL CONTINUE TO MONITOR THESE TRENDS THROUGH THE
WEEK. AT THE TAIL END OF THE LONG TERM PERIOD INTO MID WEEK, WE
ARE MONITORING RAIN CHANCES RETURNING AS AN UPPER LEVEL SHORTWAVE
IS CURRENTLY PROJECTED IN GLOBAL MODELS.
AVIATION

HOW FAR OVER NW AL CLEARING WILL OCCUR AND FOR HOW LONG. GUIDANCE

BEFORE CLEARING OUT THURSDAY MORNING. LIGHT DRIZZLE MAY CONTINUE
TO LEAD TO IFR OR PERIODS OF LIFR CONDITIONS OVERNIGHT. NORTHWEST
WINDS WILL REMAIN BREEZY BEFORE CALMING THURSDAY AFTERNOON.
