SHOWERS AND THUNDERSTORMS THAT WERE IMPACTING PORTIONS OF THE TN
VALLEY THIS AFTERNOON HAVE SINCE PUSHED EASTWARD, OUT OF THE AREA.
A COLD FRONT IS FORECAST TO PUSH SOUTHEAST INTO THE AREA

END OF THE WEEK. AHEAD OF THE COLD FRONT, DENSE FOG HAS OCCURRED
ALONG I-65 AND EASTWARD. A DENSE FOG ADVISORY HAS BEEN ISSUED FOR
THESE AREAS DUE TO VISIBILITIES DROPPING NEAR 1/4 MILE. FOG IS
EXPECTED TO BEGIN DISSIPATING WITH THE ARRIVAL OF INCREASED CLOUD
COVER AND WINDS AHEAD OF THE FRONT, WHICH SHOULD PUSH THROUGH
AROUND 4-5 AM.
WEDNESDAY, SFC HIGH PRESSURE BEGINS TO INFLUENCE THE REGION AND SKIES
ARE FORECAST TO CLEAR OUT FROM NORTHWEST TO SOUTHEAST. THIS WILL
ALLOW SUNNY CONDITIONS BY THE AFTERNOON HOURS AND HIGH
TEMPERATURES TO WARM INTO THE MID TO UPPER 50S (ABOUT 10-15
DEGREES COOLER THAN IT WAS TUESDAY AFTERNOON).
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

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.
