NEAR TERM
(REST OF TONIGHT AND THURSDAY)
ISSUED AT 907 PM CST WED DEC 24 2025
AFTER A NEAR RECORD SETTING WARM DAY, TEMPERATURES ARE SLIDING
BACK INTO THE MIDDLE 50S TO MIDDLE 60S THIS EVENING. THE COOL
SPOTS ARE IN DEKALB COUNTY WHERE THE WIND HAS BECOME CALM.
TEMP/DEW POINTS SPREADS ARE NARROWING QUICKLY THIS EVENING, SO
HAVE GONE AHEAD AND ADDED PATCHY FOG TO THE FORECAST, MAINLY IN
NORTH ALABAMA. WE WILL MONITOR THAT TREND THIS EVENING. WIDESPREAD
LOW STRATUS IS ALSO FORECAST TO DEVELOP OVERNIGHT. OVERNIGHT LOWS
WILL BE IN THE LOWER TO MIDDLE 50S. WEAK ISENTROPIC ASCENT AND
MOISTURE TRANSPORT WILL CONTINUE TO PRODUCE CLOUD COVER THROUGH
CHRISTMAS DAY, ALTHOUGH CEILINGS WILL RISE THROUGH THE DAY WITH
TEMPERATURES REACHING THE LOWER 70S IN VALLEYS AND UPPER 60S ATOP
THE HIGHER CUMBERLAND PLATEAU. OUR FORECAST HIGH AT HSV OF 73
WOULD FALL SHORT OF THE RECORD BY 4 DEGREES (77 IN 2016). AT MSL,
THE FORECAST HIGH OF 73 WOULD FALL SHORT BY 5 DEGREES (78 IN
2016). IF THE CLOUDS ARE ABLE TO DISSIPATE MORE THAN ANTICIPATED,
WE MAY SEE THESE FORECAST HIGHS GO UP A FEW DEGREES.
SHORT TERM
(THURSDAY NIGHT THROUGH SATURDAY NIGHT)
ISSUED AT 907 PM CST WED DEC 24 2025
A LOW PRESSURE SYSTEM WILL TRACK FROM THE CENTRAL PLAINS INTO
IN/OH ON FRIDAY BRINGING A WEAK COLD FRONT SOUTHEAST INTO THE OH
VALLEY THROUGH THE OZARK PLATEAU. THE FRONT NEVER GOES FURTHER AND
BASICALLY WASHES OUT AS THE 5H AND 8H RIDGES OVER THE GULF OF
AMERICA AND GULF STATES REMAINS FIRMLY ENTRENCHED THROUGH SATURDAY.
THIS MAINTAINS SOUTHWEST TO WEST LOW LEVEL FLOW AND AN UNSEASONABLY
WARM AND MOIST ATMOSPHERE IN THE TN VALLEY. THERE WILL BE
CONTINUED AREAS OF MAINLY LOW-MID LEVEL CLOUD COVER AT TIMES, BUT
RAIN CHANCES STAY 20% OR LESS THROUGH SATURDAY. HIGHS WILL REMAIN
IN THE LOWER TO MIDDLE 70S IN VALLEY LOCATIONS (UPPER 60S ATOP THE
CUMBERLAND PLATEAU) AND LOWS IN THE UPPER 50S TO AROUND 60.
LONG TERM
(SUNDAY THROUGH WEDNESDAY)
ISSUED AT 907 PM CST WED DEC 24 2025
MODELS HAVE DELAYED THE TIMING OF THE ANTICIPATED COLD FRONT BY
ABOUT 24 HOURS OVER THE PAST 2 DAYS. WHAT WAS PREVIOUSLY FORECAST TO
MOVE THROUGH ON SUNDAY NOW LOOKS LIKE IT WILL NOT ARRIVE UNTIL MONDAY
MORNING, GIVING US ONE MORE DAY OF HIGHS IN THE 70S ON SUNDAY. HAVE
NO FEAR THOUGH, IF YOU ARE TIRED OF THE WARMTH AND READY FOR WINTER
TO RETURN, IT WILL BY MONDAY AFTERNOON. POPS WILL INCREASE TO 60-80%
MONDAY MORNING AS THE FRONT MOVES THROUGH AND SHOULD DRY UP BY LATE
MONDAY AFTERNOON. ANY CHANCE OF A LIGHT WINTRY MIX WILL BE MINIMIZED
ESPECIALLY IF THE CURRENT TIMING TRENDS HOLD AND THE FRONT MOVES
THROUGH DURING THE DAYLIGHT HOURS. RAINFALL AMOUNTS STILL LOOK TO
REMAIN BELOW 0.25" AND WHILE THE COLD FRONT WILL BE STRONG, NO SEVERE
WEATHER IS FORECAST AT THIS TIME. TEMPS WILL PLUMMET BEHIND THE
FRONT, WITH HIGHS IN THE 40S ON MONDAY THEN DROPPING TO THE 30S ON
TUESDAY. OVERNIGHT LOWS WILL FALL TO THE UPPER TEENS/LOW 20S WITH
WIND CHILLS IN THE LOW TEENS TUESDAY MORNING.

CONFIDENCE ON THIS IS LOW, BUT HAVE MADE A PREVAILING IFR CIGS AND
MVFR VSBY AROUND SUNRISE. BETTER CONDITIONS SHOULD RETURN IN THE
MID AND LATTER MORNING, WITH VFR WEATHER EXPECTED THERE AFTER.
