KEY MESSAGES
- THUNDERSTORM CHANCES WILL CONTINUE THROUGH THE EVENING WITH THE
ARRIVAL OF A WEAK COLD FRONT. THERE WILL BE A CONTINUED THREAT
OF STRONG TO DAMAGING DOWNBURST WINDS, AS WELL AS HAIL.
- ABOVE NORMAL TEMPERATURES AND LESS HUMID CONDITIONS WILL
PREVAIL THROUGH THE REMAINDER OF THE WORKWEEK.
SHORT TERM
(THIS EVENING THROUGH TUESDAY NIGHT)
ISSUED AT 156 PM CDT MON SEP 21 2026
SCATTERED THUNDERSTORM ACTIVITY IS ONGOING ACROSS CENTRAL TEXAS
ALONG AN OUTFLOW BOUNDARY GENERATED FROM THIS MORNING'S
THUNDERSTORM COMPLEX IN THE ARKLATEX REGION. WITH STRONGLY BUOYANT
PARCELS, VIGOROUS UPDRAFTS HAVE BEEN ABLE TO DEVELOP, GENERATING
ISOLATED INSTANCES OF LARGE HAIL AND DAMAGING WINDS. AS THIS
ACTIVITY CONTINUES TO MOVE SOUTH, EXPECT A SIMILAR THREAT THROUGH
THE NEXT FEW HOURS.
THE TRUE FRONT IS STILL LAGGING BEHIND THIS ACTIVITY WITH THE
LATEST SURFACE ANALYSIS PLACING THE FRONT JUST NORTHWEST OF OUR
REGION. THE FRONT WILL CONTINUE TO PROGRESS SOUTHWARD THROUGH THE
REST OF THE AFTERNOON WITH THE POTENTIAL FOR ADDITIONAL
THUNDERSTORM DEVELOPMENT ALONG THE FRONT. SIMILAR TO THE
ENVIRONMENT ACROSS CENTRAL TEXAS, THERE WILL BE A THREAT FOR
STRONG TO MARGINALLY SEVERE STORMS CAPABLE OF STRONG WINDS AND
SMALL HAIL. OVERALL, COVERAGE SHOULD REMAIN SCATTERED, WITH
PROBABILITIES AROUND 20-30% ACROSS NORTH TEXAS. STORM CHANCES WILL
CONTINUE TO SHIFT SOUTH THROUGH THE EVENING, GRADUALLY DECREASING
AS DAYTIME INSTABILITY IS LOST. MOST CONVECTION SHOULD DISSIPATE
TONIGHT, LEAVING MAINLY DRY CONDITIONS OVERNIGHT.
A DRIER AIRMASS WILL BEGIN FILTERING INTO NORTH TEXAS ON TUESDAY
AS NORTHEAST WINDS BECOME ESTABLISHED BEHIND THE FRONT. THE DEEPER
MOISTURE AXIS WILL BECOME DISPLACED TOWARD WEST TEXAS,
SUBSTANTIALLY REDUCING RAIN CHANCES ACROSS MOST OF THE FORECAST
AREA. A FEW SHOWERS OR STORMS MAY STILL DEVELOP TUESDAY AFTERNOON
NEAR AND WEST OF HWY 281 WHERE BETTER MOISTURE REMAINS, BUT MOST
LOCATIONS WILL REMAIN DRY.
LONG TERM
(WEDNESDAY THROUGH NEXT SUNDAY)
ISSUED AT 156 PM CDT MON SEP 21 2026
PREDOMINANTLY DRY WEATHER IS FORECAST FROM MIDWEEK ONWARD AS
BUILDING HEIGHTS ALOFT MAINTAIN ABOVE NORMAL TEMPERATURES, WHILE
LARGE-SCALE SUBSIDENCE LIMITS RAIN CHANCES. A REINFORCING PUSH OF
DRY AIR IN EAST/NORTHEAST FLOW WILL MAINTAIN LOW DEWPOINTS IN THE
50S AND LOWER 60S, AND THIS WILL RESULT IN LESS OPPRESSIVE LATE
SEASON HEAT WITH HEAT INDEX VALUES NEAR OR BELOW AMBIENT
TEMPERATURES. HIGHS WILL STILL BE IN THE 90S FOR MOST OF THE AREA
THROUGH THE EXTENDED FORECAST PERIOD, ABOUT 5-10 DEGREES ABOVE
NORMAL FOR THE FIRST WEEK OF ASTRONOMICAL FALL. ANOTHER BREAKDOWN
OF THE RIDGE AXIS AND WEAK FRONTAL INTRUSION COULD OCCUR SOMETIME
LATE THIS WEEKEND OR EARLY NEXT WEEK WHICH WOULD BE THE NEXT
MENTIONABLE OPPORTUNITY FOR RAIN.
AVIATION
(00Z TAFS)
ISSUED AT 841 PM CDT MON SEP 21 2026
CONVECTION LARGELY REMAINED AWAY FROM THE DFW METROPLEX DURING
THE AFTERNOON, BUT ACTIVITY MOVING IN FROM THE NORTHWEST AND
CONVERGENCE OF MULTIPLE OUTFLOW BOUNDARIES LED TO AN ACTIVE PAST
COUPLE OF HOURS. WILL MAINTAIN VCTS THROUGH 03Z AT ALL METROPLEX
TAF LOCATIONS TO ACCOUNT FOR DISSIPATING CONVECTION, BUT ALL
ACTIVITY ACROSS CENTRAL TX DISSIPATED A FEW HOURS AGO. ALL
ACTIVITY WILL DISSIPATE AFTER 03Z WITH WANING INSTABILITY.
SURFACE WINDS ARE CURRENTLY BEING DETERMINED BY OUTFLOW, WHICH
WILL SHOULD MAINTAIN STEADY NORTH WINDS IN THE DFW METROPLEX FOR
ANOTHER HOUR OR SO. WINDS SHOULD THEN BECOME LIGHT NORTHEAST
AROUND 03Z, AND WILL LIKELY REMAIN AS SUCH THROUGH TUESDAY OUTSIDE
OF ANYMORE OUTFLOW-INDUCED WIND SHIFTS. VFR CAN OTHERWISE BE
EXPECTED OVERNIGHT INTO TUESDAY. ISOLATED THUNDERSTORMS ARE
POSSIBLE TUESDAY AFTERNOON, MAINLY OVER CENTRAL TEXAS, BUT
PROBABILITIES ARE TOO LOW TO INCLUDE IN ANY OF THE TAFS AT THIS
TIME.
SPOTTER INFORMATION STATEMENT
SPOTTER ACTIVATION IS NOT EXPECTED AT THIS TIME.
