AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
131 AM CDT SAT JUN 20 2026
..NEW SHORT TERM, LONG TERM, AVIATION
KEY MESSAGES
- SCATTERED SHOWERS AND THUNDERSTORMS WILL AFFECT AREAS MAINLY
ALONG AND EAST OF I-35 TODAY BEFORE COMING TO AN END THIS
EVENING. HEAVY RAINFALL, GUSTY WINDS, AND FREQUENT LIGHTNING
ARE POSSIBLE.
- HOT AND HUMID WEATHER WILL RESUME FROM SUNDAY INTO NEXT WEEK
WITH OCCASIONAL THUNDERSTORM CHANCES AND LOCALLY HEAVY RAIN
MAINLY IN NORTH TEXAS.
SHORT TERM
(TONIGHT THROUGH SUNDAY)
ISSUED AT 1150 PM CDT FRI JUN 19 2026
A SLOW-MOVING UPPER TROUGH AXIS CONTINUES TO SUPPORT NEW
DEVELOPMENT OF SHOWERS AND ISOLATED THUNDERSTORMS NEAR AND EAST
OF I-35 EARLY THIS MORNING. THIS TREND IS LIKELY TO CONTINUE FOR
THE NEXT ~12 HOURS, WITH THE DEEPEST CONVECTION OCCURRING EAST OF
I-35 AND SOUTH OF I-20. ANY PERSISTENT HEAVY RAINFALL WOULD BE
CAPABLE OF RESULTING IN ADDITIONAL LOCALIZED FLASH FLOODING.
OUTFLOWS COULD RESULT IN A NORTHWESTWARD EXPANSION OF ISOLATED
CONVECTIVE ACTIVITY THROUGH THE DAYTIME, AND LOW POPS WILL BE
INDICATED AS FAR NORTHWEST AS THE METROPLEX DURING THE AFTERNOON
PERIOD. MOST PRECIP WILL BE WINDING DOWN BY EARLY EVENING AS THE
TROUGH AXIS CONTINUES TO TRANSLATE EASTWARD, WHILE WEAK UPPER
RIDGING AND SUBSIDENCE GRADUALLY TAKES ITS PLACE. THE PRESENCE OF
SOME CLOUD COVER AND PRECIPITATION WILL AID IN HOLDING
TEMPERATURES AND HEAT INDEX VALUES BELOW HEAT ADVISORY CRITERIA
TODAY, ALTHOUGH IT STILL WILL BE SEASONABLY HOT AND MUGGY WITH
HIGHS AROUND 90 AND HEAT INDEX VALUES IN THE UPPER 90S TO AROUND
103.
ANOTHER FORECAST CONCERN THIS MORNING IS THE POTENTIAL FOR FOG
DEVELOPMENT, AND THIS WOULD BE MOST LIKELY NEAR AND WEST OF I-35
WHERE THE CIRRUS CANOPY HAS CLEARED, WHILE LIGHT NORTHEAST WINDS
AND FAVORABLE RADIATIONAL COOLING ALLOW LOW TEMPERATURES TO FALL
TO THE DEWPOINT. WE'LL CARRY A MENTION OF PATCHY FOG WEST OF THE
I-35 CORRIDOR THROUGH THE EARLY MORNING WITH QUITE A BIT OF
UNCERTAINTY IN THE PLACEMENT AND EXTENT.
BY SUNDAY, MOST OF THE PRECIPITATION POTENTIAL WILL HAVE EXITED
THE FORECAST AREA WITH ONLY SLIM AND UNMENTIONABLE 10% POPS
REMAINING ACROSS OUR SOUTHEASTERN ZONES DURING THE DAYTIME.
PORTIONS OF THE CWA ARE LIKELY TO MAKE A RETURN TO 105+ HEAT INDEX
VALUES, AND A HEAT ADVISORY WILL LIKELY BE NEEDED FOR AT LEAST
PART OF THE AREA. HOWEVER, THERE IS STILL SOME UNCERTAINTY IN THE
WEST/SOUTHWEST EXTENT OF THESE HEAT INDICES, AND SOME GUIDANCE IS
ALSO INDICATING A POTENTIAL FOR LOW CLOUDS TO LINGER THROUGH MUCH
OF THE DAYTIME WHICH OFFERS SOME BUST POTENTIAL FOR HEAT
HEADLINES. FOR THIS REASON, WE'LL HOLD OFF ON A PRODUCT ISSUANCE
AT THIS TIME WITH TOO MUCH UNCERTAINTY IN THE SPATIAL EXTENT.
THERE WILL ALSO BE A FAIRLY STOUT SOUTHERLY BREEZE THROUGH MOST
OF THE DAYTIME, WITH SUSTAINED WINDS OF 15-20 MPH AND GUSTS AS
HIGH AS 35 MPH. THIS WILL ADD SOME MODEST RELIEF TO WHAT WILL
OTHERWISE BE ANOTHER HOT AND HUMID SUMMER AFTERNOON.
LONG TERM
(SUNDAY NIGHT THROUGH NEXT FRIDAY)
ISSUED AT 1150 PM CDT FRI JUN 19 2026
AS SOUTHERLY FLOW RECOVERS AND ANOTHER FRONTAL ZONE MAKES ITS WAY
INTO THE SOUTHERN PLAINS ON SUNDAY NIGHT, OUR FOCUS WILL BE ON
UPSTREAM MCS ACTIVITY DEVELOPING ALONG THIS STATIONARY BOUNDARY
IN OKLAHOMA WHICH MAY ATTEMPT TO DIVE SOUTHWARD INTO PARTS OF
NORTH TEXAS. IN FACT, THIS PARTICULAR SETUP WILL EXIST ESSENTIALLY
ON A DAILY BASIS THROUGH THE ENTIRETY OF NEXT WEEK, AND POPS WILL
BE INDICATED MAINLY NEAR/NORTH OF I-20 JUST ABOUT EVERY DAY TO
ACCOUNT FOR THIS POTENTIAL. SINCE THESE SYSTEMS WILL BE DRIVEN ON
THE MESOSCALE, ITS NOT FEASIBLE TO PIN DOWN WHICH DAY MAY HAVE A
HIGHER CHANCE THAN ANOTHER FOR AN MCS INTRUSION AT THIS TIME
RANGE. EVEN IF THESE COMPLEXES THEMSELVES DISSIPATE PRIOR TO
CROSSING THE RED RIVER, RESIDUAL NEARBY OUTFLOW BOUNDARIES MAY
SERVE AS FOCI FOR NEW DEVELOPMENT IN PARTS OF NORTH TEXAS DURING
PEAK HEATING HOURS. AREAS THAT ARE UNAFFECTED BY CONVECTION ARE
LIKELY TO SEE A RETURN TO HEAT ADVISORY CRITERIA THROUGH MUCH OF
THE UPCOMING WEEK, AS DEWPOINTS IN THE LOW/MID 70S AND
TEMPERATURES IN THE 90S COMBINE FOR 105+ HEAT INDEX VALUES.
AVIATION
(06Z TAFS)
ISSUED AT 1150 PM CDT FRI JUN 19 2026
RAIN SHOWERS CONTINUE TO DEVELOP NEAR AND JUST EAST OF THE D10
AIRPORTS AS OF 06Z. LIGHTNING ACTIVITY HAS BEEN SCARCE WITH THIS
ACTIVITY THUS FAR, AND WILL INDICATE VCSH TO CAPTURE THIS
NEARBY PRECIPITATION AT DFW/DAL THROUGH THE NEXT FEW HOURS. MVFR
STRATUS AND PERHAPS SOME FOG MAY ATTEMPT TO FILL IN ON THE WESTERN
EDGE OF THIS ACTIVITY WHICH COULD DEGRADE FLIGHT CATEGORIES
THROUGH THE MORNING. HIGHER CHANCES FOR THUNDERSTORMS WILL
MATERIALIZE AFTER DAYBREAK, ESPECIALLY ACROSS CENTRAL TEXAS, AND
HIGHER-END TS MENTIONS WILL BE INDICATED AT WACO. OUTFLOWS FROM
SUCH ACTIVITY COULD ALLOW ISOLATED THUNDERSTORMS TO PROPAGATE
NORTHWESTWARD AND AFFECT D10 AIRPORTS ROUGHLY FROM MIDDAY INTO THE
EARLY AFTERNOON BEFORE ALL ACTIVITY WINDS DOWN THIS EVENING. MVFR
STRATUS IS LIKELY TO MAKE A RETURN HEADING INTO SUNDAY MORNING.
