DISCUSSION
ISSUED AT 219 AM CST SAT DEC 27 2025
THROUGH SUNDAY NIGHT: AREAS OF LOW CLOUDS AND FOG HAVE OVERSPREAD
MUCH OF THE AREA EARLY THIS MORNING. THOUGH MOST LOCATIONS HAVE
BEEN EXPERIENCING LOW CLOUDS, THE AREAS OF FOG HAVE BEEN DENSE IN
SPOTS THOUGH SOMEWHAT INTERMITTENT. THE CLOUD DECK MAY PERSIST
WELL INTO TODAY BEFORE MORE BREAKS DEVELOP BY THE AFTERNOON
HOURS. ONE MORE ROUND OF LOW CLOUDS IS LIKELY TONIGHT INTO SUNDAY
MORNING AS MOIST FLOW INCREASES AHEAD OF OUR NEXT STORM SYSTEM.
THERE COULD ALSO BE TRANSIENT FOG ONCE AGAIN AHEAD OF THE LOW
CLOUDS, BUT WITH INCREASING WIND OVERNIGHT, IT IS NOT EXPECTED TO
PERSIST IN MOST AREAS. THE POSSIBLE EXCEPTION WILL BE SOUTH MS
WHERE ADVECTION FOG COULD SPREAD IN FOR A FEW HOURS AROUND
DAYBREAK. SCATTERED WARM ADVECTION SHOWERS WILL BE POSSIBLE
DURING THE DAYTIME SUNDAY, BUT MOST AREAS WILL REMAIN DRY THROUGH
SUNSET. SUNDAY EVENING, A COLD FRONT WILL BEGIN ADVANCING INTO
THE AREA BRINGING A STRONGLY FORCED BUT MOSTLY NARROW BAND OF
SHOWERS. WINDS MAY BE GUSTY ALONG THE LINE, EVEN THOUGH THERE MAY
BE LITTLE TO NO LIGHTNING. ADDITIONAL SCATTERED SHOWERS ARE
EXPECTED TO FOLLOW THE FRONT, BUT OVERALL STORM TOTAL AMOUNTS
WILL BE LESS THAN A QUARTER INCH AT MOST LOCATIONS.
MONDAY THROUGH FRIDAY: STRONG COLD ADVECTION WILL MOVE IN BEHIND
THE FRONT. AS SHOWERS TAPER OFF EARLY MONDAY, IT WILL BE BLUSTERY
AND INCREASINGLY COLD. WIND CHILLS IN THE TEENS ARE EXPECTED
MONDAY NIGHT INTO TUESDAY MORNING. IT WILL REMAIN COLD THROUGH THE
DAY TUESDAY. BUT WIND WILL SLACK OFF AS THE SURFACE RIDGE AXIS
MOVES OVER THE AREA TUESDAY NIGHT INTO WEDNESDAY MORNING, WHICH
MIGHT BE THE COLDEST MORNING AT MOST LOCATIONS WITH LOWS IN THE
LOWER 20S POSSIBLE, THOUGH APPARENT TEMPS WON'T BE AS EXTREME DUE
TO THE LIGHTER WIND.
ANOTHER COLD NIGHT IS ON TAP AS WE RING IN 2026, THOUGH NOT AS
COLD AS PREVIOUS NIGHTS. AND WE'LL SEE TEMPS BEGIN TO REBOUND ON
NEW YEARS DAY. CONTINUED SURFACE RIDGING WILL MAINTAIN DRY
CONDITIONS THROUGH THURSDAY, BUT A FEW SHOWERS MAY RETURN BY
FRIDAY AS A SOUTHERN STREAM SYSTEM MOVES ACROSS THE DEEP SOUTH.
FORECAST CONFIDENCE ON TIMING/LOCATION OF THAT NEXT SYSTEM
REMAINS FAIRLY LOW AT THIS POINT IN TIME, SO DETAILS MAY CHANGE.
