DISCUSSION
(TONIGHT THROUGH NEXT FRIDAY)
ISSUED AT 1102 PM CST FRI DEC 26 2025
AMPLE RADIATIONAL COOLING, A COLD FRONT DRAPED TO OUR NORTH, AND
CALM WINDS HAS BROUGHT A GREAT ENVIRONMENT FOR PATCHY TO DENSE
FOG OVERNIGHT. WE ARE MONITORING THIS PROGRESSION CLOSELY, AS
CONDITIONS (VISIBILITIES AT OR LESS THAN 1/4SM) MAY WARRANT A
DENSE FOG ADVISORY, ESPECIALLY NORTH OF THE TENNESSEE AND
MISSISSIPPI STATELINE. A LOW STRATUS DECK WILL ALSO BEGIN TO
BUILD IN OVER THE MID-SOUTH OVERNIGHT AND LINGER THROUGH MUCH OF
THE DAY SATURDAY. PERSISTENT UPPER-LEVEL RIDGING WILL REMAIN OVER
THE MISSISSIPPI VALLEY TOMORROW, BRINGING ANOTHER DAY OF NEAR
RECORD BREAKING HIGH TEMPERATURES IN THE MID 70S.
A PATTERN CHANGE WILL OCCUR SUNDAY AS THIS RIDGE BEGINS TO SLIDE
EAST AND NORTHWEST FLOW BEGINS TO SET IN, AHEAD OF A COLD FRONT
AND AN UPPER-LEVEL TROUGH. SUNDAY MORNING, THE PRESSURE GRADIENT
AHEAD OF THE AFOREMENTIONED COLD FRONT WILL TIGHTEN AND BRING
GUSTY WINDS TO AROUND 35 MPH. A WIND ADVISORY MAY NEED TO BE
ISSUED IN LATER FORECAST PACKAGES AS CURRENT LREF PROBS HAVE >70%
CHANCE OF >35 MPH GUSTS SUNDAY. WIDESPREAD SHOWER AND ISOLATED
THUNDERSTORM CHANCES WILL BEGIN TO INCREASE SUNDAY AFTERNOON WITH
LIFT FROM THIS FRONT AND INCREASED DEWPOINTS IN THE 60S. SEVERE
WEATHER CHANCES ARE SLIM TO NONE AS THE LATEST LREF GUIDANCE HAS
AROUND A 10% CHANCE OF >200 J/KG OF SBCAPE AND >30 KTS OF WIND
SHEAR.
SHOWER CHANCES SHOULD BEGIN TO DIMINISH BY SUNRISE MONDAY AS THE
COLD FRONT PUSHES PAST THE MID-SOUTH. PRECIPITATION SHOULD END
BEFORE FREEZING TEMPERATURES ARRIVE, RESULTING IN NO MENTION OF
WINTRY PRECIPITATION MONDAY MORNING. OUR MESSAGING WILL THEN
TRANSITION TO BRISK CONDITIONS AS FREEZING TEMPERATURES WILL BE
PRESENT. THIS, IN COMBINATION WITH WIND GUSTS UP TO 35 MPH, WILL
RESULT IN WIND CHILLS BEING IN THE 20S AND 30S. HIGH TEMPERATURES
WILL ONLY REACH INTO THE 30S ALONG AND NORTH OF I-40 AND THE 40S
TO THE SOUTH ON MONDAY. TUESDAY MORNING AND TUESDAY WILL BE THE
COLDEST OF THE NEXT 7 DAY STRETCH WITH MORNING LOWS IN THE TEENS
TO LOWER 20S AND AFTERNOON HIGHS IN THE MID 30S TO LOWER 40S.
WIND CHILLS TUESDAY MORNING WILL BE IN THE LOWER TEENS ACROSS THE
BOARD.
THIS REALLY COLD SNAP WILL BE SHORT-LIVED, HOWEVER, AS SOUTHWEST
FLOW BUILDS ACROSS THE REGION BY WEDNESDAY MORNING. TEMPERATURES
WILL MODERATE CLOSER TO NORMAL WITH HIGHS REACHING INTO THE MID
40S TO LOWER 50S FOR WEDNESDAY AND THURSDAY. LONG RANGE MODELS
ARE HINTING AT ANOTHER COLD AIR MASS MOVING IN OVER THE MID-SOUTH
BY FRIDAY. STAY TUNED.
