NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
533 AM CST WED JAN 7 2026
..NEW AVIATION
KEY MESSAGES
- PATCHY TO AREAS OF FOG IS LIKELY AGAIN THIS MORNING.
- WELL ABOVE NORMAL TO NEAR RECORD HIGH TEMPERATURES ARE IN STORE
FOR TODAY THROUGH THURSDAY.
- MULTIPLE FRONTAL BOUNDARIES ARE EXPECTED TO ELEVATE FIRE WEATHER
CONCERNS THURSDAY THROUGH SATURDAY.
SHORT TERM
(TODAY THROUGH THURSDAY)
ISSUED AT 1204 AM CST WED JAN 7 2026
A DRYLINE PUSHED WELL INTO THE I-35 CORRIDOR, BUT HIGHER DEW POINT
TEMPERATURES POOLED OVER THE RIO GRANDE AND COASTAL PLAINS WILL
ADVANCE BACK NORTH OVERNIGHT. THIS OFFERS A GOOD POTENTIAL FOR
ADVECTION FOG FORMATION OVER THE COASTAL PRAIRIES AND INTO THE
I-35 CORRIDOR, BUT LESS IS ANTICIPATED FURTHER INLAND. ANOTHER
DENSE FOG ADVISORY IS POSSIBLE. MORE HUMID AIR SHOULD OVERTAKE
ALL OF THE FORECAST AREA BY MIDDAY. HIGHS TODAY MAY BE A COUPLE
DEGREES LOWER THAN TUESDAY BUT SHOULD STILL APPROACH THE VALUES
FOR RECORD HIGHS AND ALSO RECORD HIGH MINIMUMS. THURSDAY WILL ALSO
BE NEAR RECORDS, AND A DRY LINE MOVING BACK INTO THE AREA COULD
AID THE WARMING THROUGH THE WESTERLY WIND COMPONENT AND MORE
INSOLATION.
LONG TERM
(THURSDAY NIGHT THROUGH TUESDAY)
ISSUED AT 1204 AM CST WED JAN 7 2026
THURSDAY, THE DRY-LINE IS HALTED, BUT INSTEAD OF RETREATING WEST
OVERNIGHT, IT STALLS AS WESTERLY WINDS OVERRUN THE BOUNDARY TO
HELP HOLD IT IN PLACE DURING THE DECOUPLING PERIOD. THEN, BY
MIDDAY FRIDAY, A POLAR FRONT BACKED BY A POTENT UPPER TROUGH
SHOULD BRING ENOUGH DYNAMIC LIFT TO TRIGGER SOME SHOWERS AND
STORMS, PERHAPS SOME STRONG ONES, EAST OF I-35 AND NORTH OF
I-10 IN THE AFTERNOON. SPC HAS A MARGINAL RISK OVER PARTS OF
CENTRAL TX JUST NE OF OUR FORECAST AREAS, WHICH IS SOMETHING TO
BE MONITORED FOR EXPANSION.
THE AFTERNOON/EVENING ARRIVAL OF THE FRONT WOULD SUGGEST A MORE
PACIFIC STYLE FRONT, BUT LATE AT NIGHT THE ADVANCEMENT OF THE
TROUGH INTO TX IS MORE IMPACTFUL TO THE SURFACE GRADIENT, AND A
WINDY OVERNIGHT INTO SATURDAY MORNING COULD LEAD TO A WIND
ADVISORY NEED. NEEDLESS TO SAY, COOLER AIR WILL BE COMING, AND
SATURDAY INTO MONDAY TEMPERATURES SHOULD BE LOWER THAN JANUARY
NORMALS.
A RELATIVELY WEAK LOW LATITUDE UPPER DISTURBANCE MOVES ACROSS
MEXICO EARLY NEXT WEEK AND HELPS HOLD TEMPERATURES DOWN
THROUGH CLOUD COVER. THERE COULD EVEN BE SOME LIGHT PRECIP
TUESDAY. BETTER RAIN CHANCES SHOULD BE FARTHER SOUTH. MORE
SIGNIFICANT SURGES LIE AHEAD FOR LATER NEXT WEEK, SO THOSE
WONDERING WHAT HAPPENED TO JANUARY WILL FINALLY SEE A WEATHER
CORRECTION.
