KEY MESSAGES

- A COLD WEATHER ADVISORY IS IN EFFECT UNTIL NOON SUNDAY FOR
DANGEROUSLY COLD WIND CHILLS BETWEEN -5F AND +5F (FOR THIS
MORNING AND LATER TONIGHT).
- STRONG NNW WINDS OF 20-25 MPH (WITH GUSTS OF 30-35 MPH) SHOULD

NEAR TERM
(REST OF TODAY AND TONIGHT)
ISSUED AT 323 PM CST SAT JAN 31 2026
SOME FLURRIES OR VERY LIGHT SNOW SHOWERS CANNOT BE RULED OUT NEAR
AND EAST OF THE I-65 CORRIDOR THROUGH THE REMAINDER OF THE
AFTERNOON, BUT WILL NOT AMOUNT TO ADDITIONAL ACCUMULATIONS.
TEMPERATURES ARE CURRENTLY IN THE UPPER TEENS IN FAR NE AL STILL
TO THE MID 20S IN PORTIONS OF NW AL. NEAR THE AL/MS BORDER COULD
SEE A FEW LOCATIONS CLIMB TO AROUND 30 DEGREES GIVEN SOME
CONTINUED SUNSHINE IN THOSE AREAS. HOWEVER, TEMPERATURES SHOULD
START FALLING LATE THIS AFTERNOON INTO THE EVENING HOURS BACK INTO
THE UPPER TEENS AND THEN 10 TO 15 DEGREE RANGE AROUND DAYBREAK ON
SUNDAY, DESPITE CLEARING SKIES. BREEZY TO WINDY CONDITIONS WILL
CONTINUE WITH SOME IMPROVEMENT TOWARDS DAYBREAK ON SUNDAY
(SUSTAINED 5 TO 10 WITH GUSTS CLOSER TO 20 MPH BY THEN). THIS WILL
AGAIN DROP WIND CHILL VALUES INTO THE -5 TO 5 DEGREE RANGE,
ESPECIALLY EAST OF THE I-65 CORRIDOR TONIGHT INTO EARLY SUNDAY
MORNING. THUS, A COLD WEATHER ADVISORY REMAINS IN EFFECT THROUGH
NOON ON SUNDAY.
SHORT TERM
(SUNDAY THROUGH TUESDAY)
ISSUED AT 323 PM CST SAT JAN 31 2026
EXPECT SUNSHINE TO CONTINUE ON SUNDAY. WITH NNW WINDS SHIFTING
TO NORTHWESTERLY FLOW IT WILL BE WARMER THAN TODAY. HOWEVER, 925
MB TEMPERATURES DESPITE THIS FLOW ONLY WARM INTO THE -4 TO -8
DEGREE RANGE BY 4 PM. THUS, NBM LOOKS A TAD TOO WARM EVEN THOUGH
WE ARE EXPECTING SUNSHINE MOST OF THE DAY. LOWERED HIGHS TO
BETWEEN 31 AND 35 DEGREES (FREEZING TEMPERATURES MAINLY CONFINED
TO SOUTHERN MIDDLE TENNESSEE AND HIGHEST ELEVATIONS OF NE AL).
LUCKILY WINDS WILL BE MUCH LIGHTER ONLY BETWEEN 5 AND 10 MPH
MAINLY WITH SOME GUSTS TO BETWEEN 15 AND 20 MPH LINGERING EARLIER
IN THE DAY. THIS WILL HELP RELAX THE BITTERLY COLD CONDITIONS BY
THE AFTERNOON HOURS.
HOWEVER, IT WILL STILL BE COLD SUNDAY NIGHT WITH CLEAR SKIES IN
PLACE. LOWS WILL LIKELY DROP INTO THE UPPER TEENS TO AROUND 25
DEGREES. HOWEVER, LOWER DEWPOINTS WILL LIKELY KEEP FOG AT BAY
DESPITE LIGHT WINDS.
STRONGER WESTERLY TO SOUTHWESTERLY FLOW BEGINS TO DEVELOP AROUND
925 MB AND LOWER IN THE ATMOSPHERE DURING THE DAY ON MONDAY AS A
DISTURBANCE OVER WESTERN TEXAS DEVELOPS IN WNW FLOW UPSTREAM. THIS
SHOULD SIGNIFICANTLY WARM THINGS UP WITH ABUNDANT SUNSHINE DURING
THE DAY. HIGHS SHOULD REBOUND BACK INTO THE 45 TO 50 DEGREE RANGE.
BY MONDAY NIGHT, THIS DISTURBANCE MOVES EAST FROM TEXAS IN ZONAL
FLOW ALOFT INTO LOUISIANA AND ARKANSAS AREA. THIS WILL FURTHER
ADVECT WARMER AND MORE MOIST AIR INTO THE TENNESSEE VALLEY
UPSTREAM. THERE SHOULD BE ENOUGH LIFT AND MOISTURE AROUND 700 MB
FOR MID/HIGH CLOUD COVER TO BEGIN OVERSPREADING NORTHERN ALABAMA.
LOWS WITH ADDED MOISTURE ADVECTION SHOULD ONLY DROP INTO THE UPPER
20S TO LOWER 30S.
HOWEVER, BY TUESDAY MORNING THE SHORTWAVE MOVES EAST INTO THE
LOWER/MISSISSIPPI VALLEY REGION. SOME SCATTERED SHOWERS MAY JUST
EDGE INTO NW ALABAMA BY THEN. LOW LEVEL WARM AIR AND MOISTURE
ADVECTION CONTINUES TO INCREASE IN INTENSITY AS THIS OCCURS. THIS
SHOULD PUSH HIGHS INTO THE LOWER TO MID 50S IN THE AFTERNOON. RAIN
CHANCES WILL INCREASE, ESPECIALLY IN THE AFTERNOON INTO THE
EVENING HOURS BEFORE DECREASING.
LONG TERM
(TUESDAY NIGHT THROUGH SATURDAY)
ISSUED AT 323 PM CST SAT JAN 31 2026
TEMPERATURES SHOULD REMAIN A BIT WARMER ONLY DROPPING INTO THE
LOWER TO MID 30S LATE TUESDAY NIGHT. IT STILL LOOKS LIKE THIS
RAIN, BUT WE MAY EVENTUALLY SEE A BRIEF WINDOW FOR SOME KIND OF
WINTRY PRECIPITATION TOWARDS DAYBREAK ON THE WESTERN EDGE OF THIS
PRECIPITATION. HOWEVER, NOT INCLUDING THE FORECAST AT THIS TIME.
CLOUDY CONDITIONS LINGER BEHIND THE FRONT ON WEDNESDAY ACCORDING
TO GUIDANCE. THUS, BASED ON 925 MB TEMPERATURES PROGS, ENSEMBLE
DATA LOOKS A BIT TOO WARM RIGHT NOW. HOWEVER, FOR CONTINUITY SAKE
KEPT TEMPERATURES NBM PUT INTO THE FORECAST (HIGHS IN THE UPPER
30S TO LOWER 40S).
THE COLDER AIR REALLY ADVECTS INTO THE AREA WEDNESDAY NIGHT AS
LOWS DROP INTO THE UPPER TEENS TO LOWER 20S AGAIN. DESPITE
SUNSHINE, HIGHS DUE TO COLD AIR ADVECTION ON THURSDAY WILL
STRUGGLE TO REACH THE UPPER 30S TO LOWER 40S. LOWS IN THE
LOWER/MID 20S WILL CONTINUE INTO THURSDAY NIGHT.
WESTERLY FLOW EVOLVES AGAIN PROVIDING FOR INCREASING WARM
AIR/MOISTURE ADVECTION FRIDAY INTO THE WEEKEND, WHICH SHOULD WARM
THINGS UP AGAIN.
