SHORT TERM
(TODAY AND TONIGHT)
ISSUED AT 106 AM CDT TUE OCT 13 2026
THE LARGE-SCALE PATTERN IS BECOMING INCREASINGLY AMPLIFIED WITH A
DIGGING UPPER LOW/TROUGH OVER THE GREAT BASIN AND INTERMOUNTAIN
WEST WHILE RIDGING PERSISTS NEAR THE NORTHERN GULF COAST. NORTH
AND CENTRAL TEXAS REMAINS NEAR THE WESTERN FLANK OF THIS RIDGE,
KEEPING MEANINGFUL LARGE-SCALE ASCENT DISPLACED WELL TO OUR WEST
AND NORTHWEST DESPITE AN INCREASINGLY MOIST ATMOSPHERE. MEANWHILE,
CONTINUED PRESSURE FALLS ASSOCIATED WITH LEE CYCLOGENESIS ACROSS
EASTERN COLORADO WILL MAINTAIN SOUTHERLY LOW-LEVEL FLOW AND A
MOISTURE CONVEYOR EXTENDING FROM THE WESTERN GULF THROUGH TEXAS
AND INTO THE CENTRAL PLAINS.
ANOTHER SURGE OF SHALLOW GULF MOISTURE EARLY THIS MORNING WILL
RESULT IN WIDESPREAD LOW CLOUDS DEVELOPING ACROSS MUCH OF NORTH
AND CENTRAL TEXAS TOWARD DAYBREAK. PERSISTENT SOUTHERLY FLOW,
INCREASING CLOUD COVER, AND CONTINUED WARM ADVECTION WILL ALSO
MAKE FOR ANOTHER UNSEASONABLY WARM START THIS MORNING. LOW CLOUDS
WILL GRADUALLY LIFT AND SCATTER THROUGH LATE MORNING AND EARLY
AFTERNOON, ALLOWING TEMPERATURES TO AGAIN CLIMB INTO THE UPPER 80S
AND LOWER 90S.
DESPITE THE INCREASINGLY ACTIVE WEATHER EXPECTED ACROSS WEST
TEXAS AND OKLAHOMA, WIDESPREAD CONVECTION IS NOT ANTICIPATED
LOCALLY TODAY. THE STRONGEST FORCING ASSOCIATED WITH THE WESTERN
TROUGH WILL REMAIN DISPLACED WELL TO OUR NORTHWEST WHILE NORTH AND
CENTRAL TEXAS STAYS BENEATH THE DOWNSTREAM RIDGE. INSTEAD,
AFTERNOON CONVECTIVE DEVELOPMENT WILL BE LARGELY DEPENDENT ON
MESOSCALE CONVERGENCE AND DIFFERENTIAL HEATING WITHIN AN
INCREASINGLY MOIST AND UNSTABLE ENVIRONMENT. THE RICHER LOW-LEVEL
MOISTURE WILL REMAIN ACROSS CENTRAL AND EAST TEXAS WHERE ISOLATED
THUNDERSTORMS ARE MOST LIKELY DURING PEAK HEATING, PRIMARILY EAST
OF I-35. OTHERWISE, THE COMBINATION OF HIGHS MOSTLY IN THE LOWER
90S AND DEWPOINTS IN THE UPPER 60S/LOWER 70S WILL PUSH AFTERNOON
HEAT INDICES TOWARD 100 DEGREES IN SOME LOCATIONS.
ANY CONVECTION THAT MANAGES TO DEVELOP SHOULD DIMINISH THIS
EVENING WITH THE LOSS OF DAYTIME HEATING. FARTHER UPSTREAM,
HOWEVER, THE STRENGTHENING NOCTURNAL LOW-LEVEL JET WILL ENCOURAGE
CONVECTION DEVELOPING NEAR THE SOUTHERN PLAINS DRYLINE AND
FRONTAL ZONE TO EXPAND ACROSS PORTIONS OF WEST TEXAS AND OKLAHOMA
OVERNIGHT. THIS ACTIVITY SHOULD LARGELY REMAIN NORTHWEST OF OUR
FORECAST AREA THROUGH DAYBREAK WEDNESDAY.
LONG TERM
(WEDNESDAY THROUGH MONDAY)
ISSUED AT 106 AM CDT TUE OCT 13 2026
THE WESTERN UPPER TROUGH WILL SLOWLY ADVANCE EAST WEDNESDAY AS
THE GULF COAST RIDGE BEGINS TO LOSE ITS INFLUENCE OVER THE
REGION. DEEPER MOISTURE WILL INCREASINGLY ENCROACH UPON WESTERN
NORTH TEXAS, ALTHOUGH THE STRONGEST LARGE-SCALE ASCENT AND
ASSOCIATED FRONTAL FORCING WILL REMAIN NORTHWEST OF OUR FORECAST
AREA. AWAY FROM THIS UPSTREAM ACTIVITY, MUCH OF NORTH AND CENTRAL
TEXAS WILL REMAIN WITHIN A MOIST AND DIURNALLY UNSTABLE
ENVIRONMENT SUPPORTIVE OF ISOLATED TO SCATTERED AFTERNOON
THUNDERSTORMS, PARTICULARLY NEAR AND EAST OF THE I-35 CORRIDOR.
SEVERE WEATHER POTENTIAL REMAINS LOW WITH THE BEST OVERLAP OF
INSTABILITY, SHEAR, AND FORCING LOCATED NORTHWEST OF OUR AREA,
ALTHOUGH A STRONGER STORM CANNOT BE RULED OUT ACROSS WESTERN NORTH
TEXAS.
RAIN CHANCES WILL INCREASE SUBSTANTIALLY ACROSS OUR FAR
NORTHWESTERN COUNTIES WEDNESDAY EVENING AND PERSIST INTO THURSDAY
AS THE UPSTREAM SYSTEM SLOWLY APPROACHES. MOST IMPORTANTLY, THIS
WILL NOT RESEMBLE THE TYPICAL SOUTHEASTWARD PROGRESSION OF RAIN
ACCOMPANYING A STEADILY ADVANCING COLD FRONT. INSTEAD, A SHARP
NORTHWEST-TO-SOUTHEAST POP GRADIENT WILL PERSIST THROUGH MUCH OF
THE DAY THURSDAY AS THE STRONGEST LARGE-SCALE FORCING REMAINS
DISPLACED NORTHWEST OF NORTH AND CENTRAL TEXAS. THIS MEANS SOME
LOCATIONS IN OUR NORTHWEST MAY EXPERIENCE PERIODS OF SHOWERS AND
THUNDERSTORMS WHILE THE REMAINDER OF NORTH AND CENTRAL TEXAS
REMAIN LARGELY PRECIPITATION-FREE. MEANWHILE, THE WESTERN TROUGH
WILL BEGIN INTERACTING WITH A STRONG NORTHERN STREAM DISTURBANCE
DIVING SOUTHEAST FROM CANADA THURSDAY, AMPLIFYING DOWNSTREAM
TROUGHING AND FINALLY SENDING A STRONG COLD FRONT SOUTH THROUGH
THE PLAINS.
THE FRONT WILL SWEEP THROUGH NORTH AND CENTRAL TEXAS LATE THURSDAY
INTO FRIDAY MORNING, ALTHOUGH RAIN CHANCES ACCOMPANYING THE ACTUAL
FRONTAL PASSAGE MAY BE FAIRLY MODEST AS THE STRONGEST UPPER-LEVEL
FORCING LIFTS NORTHEAST. GUSTY NORTHERLY WINDS BEHIND THE FRONT
WILL USHER IN A SUBSTANTIALLY COOLER AND DRIER AIRMASS, WITH HIGHS
FALLING INTO THE UPPER 60S AND 70S THIS WEEKEND AND OVERNIGHT LOWS
IN THE UPPER 40S AND 50S. COOL AND DRY WEATHER WILL PERSIST
THROUGH THE WEEKEND BEFORE SURFACE HIGH PRESSURE SHIFTS EAST AND
SOUTHERLY FLOW GRADUALLY RETURNS. TEMPERATURES WILL BEGIN
MODERATING LATE WEEKEND INTO EARLY NEXT WEEK, WHILE A REMNANT
UPPER DISTURBANCE OVER THE SOUTHWEST COULD EVENTUALLY BRING LOW
RAIN CHANCES BACK TO THE REGION.
AVIATION
(06Z TAFS)
ISSUED AT 106 AM CDT TUE OCT 13 2026
ANOTHER SURGE OF LOW-LEVEL GULF MOISTURE WILL RESULT IN
WIDESPREAD MVFR STRATUS DEVELOPING BEFORE DAYBREAK, WITH CEILINGS
AROUND 1-1.5 KFT REACHING THE D10 TERMINALS BY 09Z. CEILINGS
SHOULD GRADUALLY LIFT THROUGH LATE MORNING TO EARLY AFTERNOON,
REACHING AROUND 2-2.5 KFT BY 16-17Z BEFORE SCATTERING TO VFR
AROUND 18-19Z. SOUTHERLY WINDS WILL INCREASE DURING THE AFTERNOON
TO AROUND 13-16 KTS. ISOLATED THUNDERSTORMS ARE EXPECTED ACROSS
PORTIONS OF CENTRAL AND EAST TEXAS DURING THE AFTERNOON, BUT
CONFIDENCE IN DIRECT IMPACTS AT KACT REMAINS TOO LOW FOR A VCTS
MENTION AT THIS TIME. CONVECTION SHOULD REMAIN SUFFICIENTLY
REMOVED FROM THE D10 TERMINALS TO PRECLUDE ANY MENTION THERE.
ANOTHER ROUND OF MVFR STRATUS IS EXPECTED TO DEVELOP TUESDAY
NIGHT, REACHING THE EXTENDED KDFW TAF AROUND 09Z WEDNESDAY.
OTHERWISE, UPSTREAM THUNDERSTORMS DEVELOPING ACROSS WEST TEXAS AND
OKLAHOMA TUESDAY NIGHT SHOULD REMAIN NORTHWEST OF THE TERMINALS
THROUGH THE CURRENT TAF PERIOD.
SPOTTER INFORMATION STATEMENT
SPOTTER ACTIVATION IS NOT EXPECTED AT THIS TIME.
