KEY MESSAGES
- DENSE FOG WILL IMPACT LAKE AND BAYS TONIGHT WITH AREAS OF DENSE
FOG POSSIBLE FARTHER INLAND.
- HIGH PRESSURE MOVING EAST OF THE REGION BRINGS MOISTURE AND WARMTH
BACK TO THE REGION INTO SUNDAY BEFORE A SHARP COLD FRONT MOVES
THROUGH INTO MONDAY.
- DRY AND COOL CONDITIONS EXPECTED THROUGH THE MIDWEEK AS A
STRONGER HIGH PRESSURE AREA AND COOL/DRY AIRMASS MOVES INTO THE
REGION.
SHORT TERM
(TODAY THROUGH MONDAY NIGHT)
ISSUED AT 518 PM CST SAT DEC 6 2025
LIGHT TO MODERATE RAIN IS SLOWLY MOVING EASTWARD AS WE ARE
FEELING THE TAIL-END EFFECTS OF THE LOW PRESSURE IN THE GULF.
UPPER-LEVEL TROUGHING CONTINUES TO INFLUENCE OUR REGION WITH WEAK
DIFFLUENCE ALOFT SUPPORTING THE OCCASIONAL WIDESPREAD RAIN. AS THE
SURFACE LOW SHIFTS EAST, HIGH PRESSURE WILL BUILD IN ITS PLACE,
LEADING TO WARM AIR ADVECTION AS MOIST GULF AIR MOVES INLAND. WE
ARE LOOKING AT THE POSSIBILITY OF DENSE FOG ACROSS MUCH OF THE
AREA WITH VISIBILITY BELOW 1 MILE. AN INLAND DENSE FOG ADVISORY
MAY BE NEEDED, BUT THERE IS TOO MUCH MODEL UNCERTAINTY TO PULL THE
TRIGGER RIGHT NOW.
SUNDAY NIGHT AND GOING INTO MONDAY, WE WILL SEE THE NEXT COLD
FRONT PUSH THROUGH THE REGION WITH BRISK NORTH WINDS AND
PLUMMETING TEMPERATURES BY 20 DEGREES, WITH LOWS DROPPING NEAR
FREEZING ALONG I-10 AND BELOW FREEZING FARTHER NORTH.
LONG TERM
(TUESDAY THROUGH SATURDAY)
ISSUED AT 518 PM CST SAT DEC 6 2025
CALM CONDITIONS WILL CONTINUE THROUGH MOST OF THE WORK WEEK AS A
LACK OF FORCING AND DRY AIR ALOFT WILL BRING CLEAR SKIES AND DRY
WEATHER. TEMPERATURES WILL SLOWLY RISE AS CLEAR SKIES AND WARM AIR
ADVECTION WILL BUMP OUR HIGHS INTO THE LOW 70S AND OUR LOWS INTO
THE UPPER 40S TO LOW 50S. THE NEXT COLD FRONT WILL MOVE THROUGH
NEAR THE END OF THE WEEK, BUT WITH PWATS IN THE 25TH PERCENTILE,
THE CHANCE OF RAIN WILL BE NEAR ZERO THROUGH THE EXTENDED
FORECAST.
AVIATION
(00Z TAFS)
ISSUED AT 523 PM CST SAT DEC 6 2025
WITH HIGH PRESSURE AT THE SURFACE MOVING OFF TO THE EAST SOUTHERLY
FLOW IN THE LOW LEVELS RETURNING BRINGING SOME WARM AIR AND
MOISTURE ADVECTION INTO THE REGION. THIS IS ALLOWING FOR LOW
CLOUDS TO DEVELOP WITH MVFR/IFR CEILINGS AT ALL TERMINALS EXCEPT
FOR KAEX, WHICH REMAINS AT VFR FOR THE MOMENT.
DURING THE NIGHT, LOW CLOUDS WILL CONTINUE TO MOVE INLAND WITH
STRATUS BUILD DOWN BRINGING ABOUT SOME PATCHY FOG ALSO. ALL
TERMINALS ARE EXPECTED IN THE IFR/LIFR MODE FROM ROUGHLY
07/06-15Z.
A COLD FRONT WILL MOVE ACROSS THE AREA DURING SUNDAY AFTERNOON. A
FEW SHOWERS WILL BE POSSIBLE AHEAD OF THE FRONT WITH MAINLY MVFR
CEILINGS, THEN SHOWERS ENDING AFTER THE FRONT, HOWEVER MVFR
CEILINGS LOOK TO PERSIST.
