NATIONAL WEATHER SERVICE FORT WORTH TX
200 PM CDT TUE SEP 29 2026
..NEW SHORT TERM, LONG TERM, AVIATION
KEY MESSAGES
- A FLOOD WATCH IS IN EFFECT FOR MUCH OF NORTH AND CENTRAL TEXAS
THROUGH FRIDAY MORNING.
- A COUPLE STRONG TO SEVERE THUNDERSTORMS ARE POSSIBLE ALONG AND
WEST OF THE US-281 CORRIDOR WEDNESDAY AFTERNOON AND EVENING.
- MUCH COOLER WEATHER IS EXPECTED THIS WEEKEND WITH CONTINUED
CLOUDS AND SCATTERED SHOWERS/STORMS LINGERING THROUGH SUNDAY.
SHORT TERM
(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 200 PM CDT TUE SEP 29 2026
..TUESDAY AND TUESDAY NIGHT
THE REST OF TODAY AND TONIGHT WILL REMAIN QUIET ACROSS NORTH AND
CENTRAL TEXAS AS UPPER-LEVEL RIDGING SLOWLY SHIFTS TO THE EAST.
TEMPERATURES WILL REMAIN ABOVE AVERAGE WITH HIGHS IN THE LOW TO
MID-90S.
WITH THE APPROACH OF THE PRIMARY UPPER-LEVEL DISTURBANCE TO THE
WEST, SURFACE CYCLOGENESIS IS EXPECTED IN THE SOUTHERN HIGH
PLAINS. AS A RESULT, THE PRESSURE GRADIENT SHOULD TIGHTEN ACROSS
THE REGION RESULTING IN GUSTY WINDS OF 15-25 MPH.
..WEDNESDAY
BY WEDNESDAY, THE PRIMARY UPPER-LEVEL DISTURBANCE WILL MOVE FROM
THE FOUR-CORNERS REGION INTO THE SOUTHERN ROCKIES. AT THE SURFACE,
A LOW PRESSURE CENTER IS EXPECTED TO DEVELOP IN THE PROXIMITY OF
THE TEXAS PANHANDLE BEFORE MOVING NORTHEAST INTO THE CENTRAL
PLAINS. A PACIFIC FRONT WILL EXTEND SOUTHWARD FROM THE LOW-
PRESSURE INTO CENTRAL TEXAS. WITH STRONG FORCING FOR ASCENT AND
SUBSTANTIAL MOISTURE IN PLACE (PWATS POTENTIALLY EXCEEDING 2
INCHES), SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO
DEVELOP IN PROXIMITY TO THIS FRONTAL ZONE BY THE AFTERNOON HOURS
ON WEDNESDAY.
THERE WILL BE THE POTENTIAL FOR A COUPLE STRONG TO SEVERE
THUNDERSTORMS WEDNESDAY AFTERNOON AND EVENING PRIMARILY ALONG AND
WEST OF THE US-281 CORRIDOR. THIS WILL BE OWING TO SUFFICIENT
DEEP-LAYER SHEAR (30-40 KNOTS) AND MODEST INSTABILITY (MLCAPE
1000-1500 J/KG). THERE WILL BE LOCALIZED AREAS WITH ENHANCED 0-1
KM SHEAR (ESPECIALLY IN PROXIMITY TO THE STRONGER STORMS) WITH
SHEAR MAGNITUDES OF 15-25 KNOTS. HOWEVER, THE LOW-LEVEL SHEAR
PROFILE LACKS CURVATURE WITH 0-1KM SRH GENERALLY 100 M2/S2 OR
LESS. AS SUCH, THOUGH A TORNADO OR TWO CAN'T BE RULED OUT IN THE
BIG COUNTRY, THIS THREAT LOOKS RATHER LOW AT THE MOMENT. AS SUCH,
THE PRIMARY HAZARDS IN ANY SEVERE STORM WILL BE FOR LARGE HAIL AND
DAMAGING WINDS.
LONG TERM
(WEDNESDAY NIGHT THROUGH NEXT MONDAY)
ISSUED AT 200 PM CDT TUE SEP 29 2026
..WEDNESDAY NIGHT THROUGH THURSDAY NIGHT
WEDNESDAY NIGHT WIDESPREAD THUNDERSTORMS ARE EXPECTED ALONG THE
NEARLY STATIONARY FRONTAL ZONE EXTENDING FROM THE TEXAS HILL
COUNTRY INTO OKLAHOMA. STORM MOTIONS WILL BE NEARLY PARALLEL THE
SURFACE BOUNDARY RESULTING IN AN INCREASING RISK FOR FLASH
FLOODING THROUGHOUT THE OVERNIGHT. THIS FLOODING THREAT WILL
BE MAXIMIZED ALONG AND WEST OF THE US-281 CORRIDOR, THOUGH
ISOLATED INSTANCES OF FLASH FLOODING CAN'T BE RULED OUT CLOSER TO
THE I-35 CORRIDOR BY SUNRISE THURSDAY MORNING. BY THURSDAY THE
GREATEST FLASH FLOODING THREAT WILL SHIFT MORE TOWARDS THE I-35
CORRIDOR AS TRAINING SHOWERS AND THUNDERSTORMS CONTINUE TO SLOWLY
MOVE EAST. BY THURSDAY NIGHT, THE UPPER-LEVEL DISTURBANCE WILL
LIFT TO THE NORTHEAST RESULTING IN MORE SCATTERED COVERAGE OF
SHOWERS AND THUNDERSTORMS. WHILE ISOLATED INSTANCES OF FLASH
FLOODING WILL STILL BE POSSIBLE (ESPECIALLY ALONG AND WEST OF THE
I-35 CORRIDOR), THE FLOODING THREAT SHOULD GENERALLY START TO
DECREASE BY THURSDAY NIGHT.
WEDNESDAY NIGHT THROUGH THURSDAY NIGHT RAINFALL TOTALS WILL BE 1-3
INCHES FOR MOST. ISOLATED POCKETS OF 4-6 INCHES OF RAIN ARE
EXPECTED, ESPECIALLY BETWEEN THE I-35 AND US-281 CORRIDORS.
TEMPERATURES WILL ALSO FINALLY DIP BELOW AVERAGE DUE TO THE RAIN
AND CLOUD COVER IN THE AREA. THURSDAY HIGHS WILL BE IN THE 80S FOR
MOST WITH THE INCREASED CLOUD COVER AND RAIN IN THE AREA.
LOCATIONS THAT SEE THE MOST PERSISTENT RAIN WEDNESDAY NIGHT INTO
THURSDAY MAY REMAIN IN THE 70S THURSDAY AFTERNOON. AREAS IN AND
AROUND THE BRAZOS VALLEY MAY ONCE AGAIN WARM INTO THE LOW-90S AS
RAIN WILL STRUGGLE TO PUSH EASTWARD INTO THESE AREAS.
..FRIDAY THROUGH SUNDAY
THOUGH THE MAIN UPPER-LEVEL SHORTWAVE WILL MOVE WELL TO THE
NORTHWEST TOWARDS THE MIDWEST AND GREAT LAKES BY THIS WEEKEND,
WEAK TROUGHING WILL REMAIN OVER THE SOUTHERN PLAINS AND ROCKIES.
AT THE SURFACE, A WEAK FRONTAL BOUNDARY WILL REMAIN ACROSS THE
REGION. THERE IS UNCERTAINTY WITH HOW FAR SOUTH THIS BOUNDARY WILL
PUSH, AND WHAT ITS EVOLUTION WILL BE THROUGHOUT THE WEEKEND.
REGARDLESS, LOW-LEVEL FORCING IN PROXIMITY TO THIS BOUNDARY ALONG
WITH WEAK FORCING FOR ASCENT ON THE LEEWARD SIDE OF THE
AFOREMENTIONED UPPER-LEVEL TROUGH WILL ALLOW SCATTERED SHOWERS AND
NON-SEVERE THUNDERSTORMS TO REMAIN ACROSS NORTH AND CENTRAL TEXAS
THIS WEEKEND. RAIN CHANCES WILL GRADUALLY DECREASE THROUGH SUNDAY
AFTERNOON WHEN MEDIUM-RANGE GUIDANCE DEPICTS A MORE SUBSTANTIAL
COLD FRONT MOVING THROUGH THE REGION FROM NORTH TO SOUTH. WEAK CAA
AT THE SURFACE ALONG WITH CONTINUED CLOUD COVER AND RAIN ACROSS
THE REGION WILL ALSO KEEP TEMPERATURES BELOW AVERAGE THIS WEEKEND
WITH HIGHS IN THE UPPER-70S AND LOWER-80S.
..MONDAY ONWARD
BY MONDAY, MEDIUM RANGE GUIDANCE HAS A MUCH MORE FALL-LIKE AIRMASS
IN PLACE ACROSS THE REGION. WEAK SHORTWAVES EMBEDDED IN
INCREASINGLY NORTHWESTERLY FLOW ALOFT WILL BRING SEVERAL
REINFORCING SHOTS OF COOL FALL AIR TO MUCH OF THE CONUS, OF WHICH
SHOULD MAKE IT AS FAR SOUTH AS NORTH AND CENTRAL TEXAS. THIS WILL
KEEP TEMPERATURES IN THE 70S AND 80S AND BRING MUCH DRIER (DEW
POINTS SHOULD FALL INTO THE 50S BY MID-WEEK NEXT WEEK). WHILE
THIS WILL ALLOW FOR WARMER AFTERNOON HIGHS THAN THIS WEEKEND,
OVERNIGHT LOWS WILL BE MUCH COLDER IN THE UPPER-50S AND LOWER-60S.
AVIATION
(18Z TAFS)
ISSUED AT 200 PM CDT TUE SEP 29 2026
A DECK OF MVFR CIGS IS EXPECTED TO DEVELOP ACROSS CENTRAL TX
(KACT) SOMETIME BETWEEN 08Z AND 10Z. THE NORTHERN EXTENT OF THESE
CIGS WILL MOVE QUICKLY NORTH INTO D10 SOMETIME BETWEEN 09Z AND
11Z. THERE IS SOME UNCERTAINTY WITH WHEN THESE CEILINGS SHOULD
GIVE WAY TO VFR, BUT CURRENT GUIDANCE SHOWS THIS TRANSITION
BETWEEN 16Z AND 19Z. OTHERWISE, EXPECT SOUTH/SOUTHEASTERLY WINDS
TO GRADUALLY STRENGTHEN THROUGHOUT THE COURSE OF THIS FORECAST
PERIOD FROM 10-15 KNOTS TO 15-20 KNOTS. GUSTS UP TO 30 KNOTS WILL
BE POSSIBLE TOMORROW AFTER 12Z ONCE CLOUD COVER DISAPPEARS.
