NEAR TERM
(TODAY)
ISSUED AT 404 AM CST WED NOV 26 2025
AN AREA OF CLOUD COVER ALONG AND BEHIND A FRONT THAT IS PRODUCING
MAINLY CLOUD COVER OVER NORTHERN ALABAMA AND SOUTHERN MIDDLE
TENNESSEE CONTINUES TO PUSHES SOUTHEAST THROUGH PORTIONS OF NW
ALABAMA RIGHT NOW. WINDS ARE A BIT STRONGER 5 TO 10 MPH WITH SOME
GUSTS BETWEEN 10 AND 15 MPH NEAR AND BEHIND THAT FRONT. THE CLOUDS
AND ESPECIALLY THE INCREASE IN WINDS IS HELPING TO DISPERSE FOG
THAT FORMED IN A MORE WIDESPREAD FASHION EARLIER TUESDAY EVENING.
A VERY FEW ISOLATED SPOTS IN SHELTERED VALLEY LOCATIONS OF NE
ALABAMA STILL HAVE SOME PATCHY DENSE FOG, BUT THAT TOO SHOULD LIFT
AS THE FRONT MOVES INTO THAT ARE SHORTLY. TEMPERATURES WILL
MAINLY FALL DUE TO COLD AIR ADVECTION THIS MORNING, BUT THIS
COOLDOWN WILL BE HAMPERED BY CLOUD COVER NEAR AND EAST OF THE
I-65 CORRIDOR. BY DAYBREAK, THIS ADVECTION SHOULD BE ABLE TO DROP
TEMPERATURES INTO THE MID TO UPPER 40S NEAR AND WEST OF THE I-65
CORRIDOR AND AROUND 50 DEGREES FURTHER EAST.
SOME MORNING CLOUD COVER WILL LIKELY LINGER, MAINLY EAST OF THE
I-65 CORRIDOR, BUT OTHERWISE SUNNY SKIES ARE EXPECTED WITH THE
EASTERN PORTION OF A SURFACE HIGH BUILDING TOWARDS THE AREA.
DECENT WINDS BETWEEN 15 AND 20 KNOTS ARE SEEN IN MOST AREA
SOUNDINGS, SO SOME GUSTS LOOK LIKELY BETWEEN 15 AND 20 MPH INTO
THE AFTERNOON HOURS.
SHORT TERM
(WEDNESDAY NIGHT THROUGH FRIDAY)
ISSUED AT 941 PM CST TUE NOV 25 2025
DRY CONDITIONS ARE FORECAST TO CONTINUE THROUGH THE SHORT TERM
PERIOD AS SFC HIGH PRESSURE RESIDES OVER THE REGION. POST-FRONTAL
TEMPERATURES WILL BE MUCH COOLER, WITH OVERNIGHT LOWS DROPPING
BELOW FREEZING (INTO THE MID 20S TO LOW 30S) THROUGH MOST OR ALL
OF THE AREA WEDNESDAY AND THURSDAY NIGHT. HIGHS DURING THIS TIME
WILL REACH THE LOW 40S TO 50S. IF YOU HAVE ANY THANKSGIVING PLANS,
MULTIPLE LAYERS WILL BE ENCOURAGED. A PATTERN CHANGE COMES OVER
THE WEEKEND, WHICH YOU CAN READ MORE ABOUT IN THE LONG TERM
SECTION BELOW.
LONG TERM
(FRIDAY NIGHT THROUGH TUESDAY)
ISSUED AT 941 PM CST TUE NOV 25 2025
ONE MORE DRY DAY ON SATURDAY AS HIGH PRESSURE WILL REMAIN THE
DOMINANT WEATHER FEATURE -- THROUGH INCREASING CLOUD COVER WILL
CAP ANY POTENTIAL HEATING AND KEEP HIGH TEMPERATURES IN THE MID
50S. A PATTERN CHANGE IS COMING LATE THIS WEEKEND AS HIGH
PRESSURE QUICKLY SCOOTS OFF TO THE EAST ON SATURDAY AND ANOTHER
TROUGH SWINGS FROM THE CENTRAL/SOUTHERN PLAINS INTO THE MID
MISSISSIPPI AND OHIO VALLEY. THIS WILL FORCE A COLD FRONT THROUGH
THE TENNESSEE VALLEY AND DEEP SOUTH. AHEAD OF THIS FRONT,
SOUTHERLY WINDS WILL HELP TO ADVECT IN SOME RETURN FLOW MOISTURE
FROM THE GULF. FORCING FROM THE TROUGH AND ALONG THE FRONT WILL
GENERATE LIGHT RAIN SHOWERS SATURDAY NIGHT, THAT WILL BECOME MUCH
MORE NUMEROUS (60-70% CHANCE) SUNDAY AND SUNDAY NIGHT AS THE FRONT
PASSES ACROSS THE REGION. RAINFALL TOTALS UP TO 1" SEEM PLAUSIBLE
WITH THIS INITIAL ROUND OF PRECIPITATION. A BRIEF "LULL" WILL
OCCUR ON MONDAY, BEFORE AN ADDITIONAL STORM SYSTEM WILL FORM ALONG
THE GULF -- BRINGING WIDESPREAD SHOWERS AND A FEW STORMS (60-80%)
MONDAY NIGHT INTO TUESDAY. THIS SLOWER MOVING SYSTEM MAY BRING
SOME LOCALLY HEAVY RAINFALL ON THE ORDER OF 1-2" WHICH COULD
RESULT IN SOME MINOR RISES ON CREEKS AND STREAMS. DENSE CLOUD
COVER AND HIGH RAIN CHANCES WILL KEEP HIGH TEMPERATURES ON THE
COOL SIDE IN THE UPPER 40S.
