KEY MESSAGES
- ISOLATED SHOWERS AND THUNDERSTORMS ARE POSSIBLE AGAIN THIS
AFTERNOON, BUT MOST AREAS WILL STAY DRY.
- MORE WIDESPREAD SHOWERS AND STORMS ARE EXPECTED TUESDAY AND
WEDNESDAY AS A COLD FRONT MOVES INTO AND STALLS ACROSS THE
REGION. HEAVY RAINFALL AND SOME STRONG TO SEVERE STORMS ARE
POSSIBLE BOTH DAYS.
- DAILY CHANCES FOR SCATTERED SHOWERS AND STORMS WILL CONTINUE
THE REST OF THE WEEK INTO THE WEEKEND. LOCALLY HEAVY RAIN WILL
BE POSSIBLE BUT THE SEVERE WEATHER THREAT APPEARS LOW.
SHORT TERM
(THIS EVENING THROUGH TUESDAY)
ISSUED AT 139 PM CDT MON MAY 18 2026
A WARM, HUMID, AND WINDY AFTERNOON IS UNDERWAY ACROSS NORTH AND
CENTRAL TEXAS AS STRONG SOUTHERLY FLOW CONTINUES AHEAD OF A
DRYLINE TO OUR WEST AND A COLD FRONT MOVING INTO THE SOUTHERN
PLAINS. THE SPECIAL 18Z SOUNDING STILL SHOWS A SIZABLE CAP IN
PLACE, WHICH SHOULD SUPPRESS MOST CONVECTIVE ATTEMPTS THROUGH THIS
AFTERNOON. INCREASING BROAD-SCALE LIFT MAY STILL ALLOW AN
ISOLATED SHOWER OR STORM TO DEVELOP AWAY FROM THE DRYLINE, SIMILAR
TO WHAT OCCURRED YESTERDAY, BUT THE DRYLINE REMAINS THE BETTER
FOCUS FOR ANY MORE SUSTAINED CONVECTION LATE THIS AFTERNOON AND
EARLY EVENING. ANY STORM THAT DEVELOPS SHOULD REMAIN ISOLATED,
WITH STEEP LAPSE RATES SUPPORTING SOME HAIL POTENTIAL AND
COLLAPSING CORES CAPABLE OF PRODUCING STRONG DOWNBURST WINDS.
THE COLD FRONT WILL MOVE INTO NORTH TEXAS TUESDAY MORNING,
REACHING THE I-20 CORRIDOR AROUND MIDDAY AND CENTRAL TEXAS BY LATE
AFTERNOON OR EARLY EVENING. SHOWERS AND STORMS SHOULD INCREASE IN
COVERAGE ALONG THE FRONT AS IT MOVES INTO A MOIST AND UNSTABLE
AIRMASS, WITH THE HIGHEST RAIN CHANCES GRADUALLY SHIFTING SOUTH
AND EAST THROUGH THE DAY. DAMAGING WINDS AND HAIL WILL BE THE
PRIMARY SEVERE HAZARDS, WITH THE OVERALL INTENSITY TIED TO HOW
MUCH INSTABILITY CAN BUILD AHEAD OF THE BOUNDARY AND HOW MUCH
INFLUENCE ANY PRIOR OUTFLOW HAS ON THE FRONTAL ZONE. ACTIVITY
SHOULD GRADUALLY DIMINISH FROM NORTH TO SOUTH TUESDAY EVENING AS
THE FRONT SETTLES INTO CENTRAL TEXAS, WITH COOLER AIR FILTERING
INTO NORTH TEXAS BEHIND THE BOUNDARY.
LONG TERM
(TUESDAY NIGHT THROUGH NEXT SUNDAY)
ISSUED AT 139 PM CDT MON MAY 18 2026
THE FRONT WILL SLOW AND BECOME DRAPED ACROSS CENTRAL OR SOUTHEAST
TEXAS TUESDAY NIGHT INTO WEDNESDAY WHILE SOUTHWEST FLOW PERSISTS
ALOFT. SHOWERS AND STORMS WILL REMAIN POSSIBLE NEAR AND NORTH OF
THE BOUNDARY, BUT WEDNESDAY CURRENTLY LOOKS LIKE A RELATIVE
MINIMUM IN RAIN CHANCES FOR MUCH OF NORTH AND CENTRAL TEXAS AS THE
BETTER FORCING AND DEEPER MOISTURE CONVERGENCE FOCUS FARTHER EAST
AND SOUTHEAST. POPS WILL REMAIN IN THE FORECAST AREA-WIDE, BUT
THE HIGHEST COVERAGE SHOULD FAVOR EAST TEXAS AND SOUTHEAST TEXAS
DURING THIS PERIOD. TEMPERATURES WILL TREND COOLER BEHIND THE
FRONT, WITH CLOUDS AND SCATTERED PRECIPITATION KEEPING MANY AREAS
NEAR OR BELOW SEASONAL NORMALS THROUGH MIDWEEK.
RAIN AND STORM CHANCES SHOULD INCREASE AGAIN ON THURSDAY AS A
COMPACT SHORTWAVE EMBEDDED IN THE SOUTHWEST FLOW PIVOTS ACROSS
CENTRAL TEXAS WHILE THE REMNANT FRONTAL ZONE REMAINS NEARBY. THIS
SETUP SHOULD PROVIDE A BETTER OVERLAP OF ASCENT, MOISTURE, AND
BOUNDARY-FOCUSED LIFT, SUPPORTING ANOTHER ROUND OF MORE WIDESPREAD
SHOWERS AND THUNDERSTORMS. SEVERE WEATHER POTENTIAL APPEARS
LIMITED BY WEAKER SHEAR AND LESS FAVORABLE INSTABILITY COMPARED TO
MONDAY AND TUESDAY, BUT LOCALLY HEAVY RAINFALL WILL BECOME A
GREATER CONCERN. THIS WILL BE A CUMULATIVE RAINFALL EVENT, AND BY
THURSDAY THE EARLIER ROUNDS OF RAIN MAY BEGIN TO MOISTEN THE TOP
LAYER OF SOILS ENOUGH TO LOWER RUNOFF THRESHOLDS, ESPECIALLY WHERE
STORMS REPEATEDLY MOVE OVER THE SAME AREAS.
PERIODIC RAIN AND STORM CHANCES WILL CONTINUE FRIDAY INTO THE
HOLIDAY WEEKEND AS ADDITIONAL WEAK DISTURBANCES MOVE THROUGH THE
PERSISTENT SOUTHWEST FLOW. THE PLACEMENT OF THE OLD FRONTAL ZONE
AND ANY CONVECTIVE OUTFLOW BOUNDARIES WILL CONTINUE TO DRIVE THE
LOCATION OF THE HEAVIEST RAINFALL FROM DAY TO DAY, KEEPING
CONFIDENCE LOWER IN THE EXACT CORRIDOR OF HIGHER TOTALS. THE
OVERALL PATTERN SUPPORTS BENEFICIAL RAINFALL FOR MANY AREAS, BUT
LOCALIZED FLOODING CONCERNS MAY INCREASE WHERE REPEATED ROUNDS
OCCUR, PARTICULARLY ACROSS CENTRAL TEXAS, EAST TEXAS, AND THE
BRAZOS VALLEY. SEVERE WEATHER POTENTIAL SHOULD REMAIN LOW LATE
WEEK INTO THE WEEKEND, WITH LOCALLY HEAVY RAIN AND OCCASIONAL
LIGHTNING BECOMING THE MAIN CONCERNS.
AVIATION
(18Z TAFS)
ISSUED AT 139 PM CDT MON MAY 18 2026
STRONG SOUTH WINDS WILL REMAIN THE PRIMARY AVIATION CONCERN
THROUGH THE AFTERNOON AND EARLY EVENING WITH SUSTAINED SPEEDS
AROUND 20-25 KT AND GUSTS TO NEAR 30-35 KT. VFR WILL PREVAIL
THROUGH THE EVENING, WITH WINDS GRADUALLY DECREASING AFTER
SUNSET. ANOTHER ROUND OF MVFR CEILINGS WILL ARRIVE LATE TONIGHT
INTO EARLY TUESDAY MORNING, GENERALLY 06-09Z, WITH THE LOWEST CIGS
LIKELY ACROSS CENTRAL TEXAS INCLUDING KACT.
A COLD FRONT WILL MOVE INTO NORTH TEXAS ON TUESDAY WITH SHOWERS
AND THUNDERSTORMS EXPECTED TO CROSS THE RED RIVER BY MID MORNING
AND MOVE THROUGH THE REGION THROUGH THE AFTERNOON AND EVENING.
THE MOST LIKELY WINDOW FOR IMPACTS AT THE METROPLEX TERMINALS WILL
BE 19-23Z, WITH GUSTY AND ERRATIC WINDS, BRIEF VISIBILITY
REDUCTIONS, AND MVFR/BRIEF IFR CONDITIONS POSSIBLE IN HEAVIER
STORMS. TIMING AND PLACEMENT DETAILS WILL CONTINUE TO BE REFINED
IN LATER TAF ISSUANCES, BUT A WIND SHIFT WILL LIKELY ACCOMPANY THE
FRONT AND ANY STRONGER STORM OUTFLOWS.
