NEAR TERM
(TODAY)
ISSUED AT 320 AM CST WED DEC 31 2025
CLEAR SKIES AND CHILLY CONDITIONS PREVAILED OVER AND AROUND THE
GREATER TENNESSEE VALLEY AS WE CLOSE OUT THE YEAR. TEMPERATURES AT
3 AM WERE MAINLY IN THE 20S (WITH A 30 IN GUNTERSVILLE) WITH LIGHT
WINDS. DEWPOINT TEMPERATURES WERE GENERALLY 5-10 DEGREES COOLER
THAN THE AIR TEMPS, THUS FOG SHOULD NOT BE AN ISSUE THIS MORNING.
BROAD HIGH PRESSURE SITUATED ACROSS TEXAS CONTINUED CONTROLLING
THE AREA'S SENSIBLE WEATHER.
AS DAYTIME HEATING AND THE MIXING OF WINDS TO THE SURFACE
COMMENCES, TEMPERATURES WILL MODERATE, RISING CLOSE TO SEASONABLE
NORMS LATER TODAY. THUS FOR THE LAST DAY OF YEAR, HIGHS SHOULD
WARM INTO THE UPPER 40S AND LOWER 50S, WITH SW WINDS OF 5-10 MPH.
NORMAL HIGH/LOW TEMPERATURES THIS TIME OF YEAR ARE AROUND 52/34.
IN A NW FLOW ALOFT, SOME HIGH CLOUDS OVER THE NORTHERN PLAINS
SHOULD MOVE ACROSS THE AREA DURING THE COURSE OF THE DAY.
SHORT TERM
(TONIGHT THROUGH FRIDAY NIGHT)
ISSUED AT 955 PM CST TUE DEC 30 2025
ONE MORE NIGHT WITH SUB-FREEZING TEMPS IF FORECAST FOR NEW YEARS
EVE, SO BE SURE TO WEAR MULTIPLE WARM LAYERS IF SPENDING TIME
OUTDOORS ESPECIALLY LATE WEDNESDAY NIGHT INTO THURSDAY MORNING! THE
OVERALL SYNOPTIC PATTERN WILL CHANGE LITTLE THROUGH THURSDAY,
WITH DRY WEATHER AND TEMPS IN THE LOW TO MID 50S ON NEW YEARS DAY.
THE MAIN FOCUS IN THE SHORT TERM PERIOD WILL BE A SHORTWAVE
DISTURBANCE PROGGED TO MOVE THROUGH FRIDAY NIGHT INTO SATURDAY.
OVERALL, NOT MUCH HAS CHANGED REGARDING THE FORECAST FOR THIS
SYSTEM AS THE BEST THUNDERSTORM DYNAMICS WILL REMAIN TO OUR SOUTH.
AS A MATTER OF FACT, EVEN ELEVATED INSTABILITY HAS TRENDED LOWER
AND HAS RESULTED IN LOW THUNDERSTORM CHANCES FOR AREAS IN AND
SOUTH OF CULLMAN COUNTY. RAINFALL AMOUNTS STILL LOOK TO AVERAGE IN
THE 0.5-0.75" RANGE, BUT SOME LOCATIONS COULD SEE AMOUNTS CLOSER
TO AN INCH. RAIN SHOULD BEGIN TO CLEAR THE AREA FROM WEST TO EAST
BY SUNRISE SATURDAY MORNING.
LONG TERM
(SATURDAY THROUGH TUESDAY)
ISSUED AT 955 PM CST TUE DEC 30 2025
AS THE SYSTEM PASSES TO OUR SOUTH, WE COULD SEE A FEW WRAP AROUND
SHOWERS ON SATURDAY, WITH THE GREATEST COVERAGE EAST OF I-65. AS WE
GO THROUGH THE WEEKEND, WE WILL SEE SFC HIGH PRESSURE BUILD INTO THE
REGION, BUT THE CENTER OF THE UPPER LEVEL RIDGE WILL BE STUCK IN THE
GULF. THIS WILL KEEP US IN NORTHWESTERLY FLOW ALOFT AND HELP KEEP
DAYTIME HIGHS IN THE 50S AND LOWS IN THE 30S. AS THE RIDGE SLIDES
EASTWARD EARLY NEXT WEEK, IT WILL PROVIDE ANOTHER ROUND OF WARMER
THAN NORMAL TEMPS IN THE LOWER 60S.
