DISCUSSION
ISSUED AT 1218 PM CDT TUE JUN 9 2026
SUBTROPICAL RIDGING ALOFT WILL REMAINED CENTERED OVER SOUTHEAST
TEXAS THROUGH THE END OF THE WEEK. LOW-LEVEL FLOW WILL REMAIN
ONSHORE, OUT OF THE SSE AROUND THE WEST SIDE OF THE BERMUDA HIGH.
ISOLATED TO SCATTERED SHOWERS AND A COUPLE STORMS ARE EXPECTED
EACH DAY DURING THE LATE MORNING AND AFTERNOON HOURS ALONG THE SEA
BREEZE, WITH THE RELATIVELY HIGHEST CHANCES ALONG AND NORTH OF
I-10. HOT AND HUMID CONDITIONS WILL CONTINUE. PROBABILITIES OF
REACHING THE OFFICIAL ADVISORY CRITERIA OF 108F REMAIN LOW, BUT
THERE ARE MEDIUM CHANCES OF HEAT INDICES REACHING 105 DEGREES THAT
WILL IMPACT THOSE NOT ACCLIMATED TO THE HEAT, ESPECIALLY GIVEN
THAT THESE ARE THE HIGHEST HEAT INDICES SO FAR THIS SUMMER.
COVERAGE OF DIURNAL CONVECTION WILL BEGIN TO INCREASE DURING THE
SUNDAY/MONDAY TIMEFRAME, AS THE RIDGE ALOFT WEAKENS IN RESPONSE TO
A TROUGH AMPLIFYING OVER THE CENTRAL CONUS. PWATS WILL INCREASE
ABOVE 2 INCHES DUE TO THE COMBINATION OF A STALLING FRONTAL
BOUNDARY TO OUR NORTH AND A FEED OF TROPICAL MOISTURE COMING IN
FROM THE SOUTH. THIS MAY RESULT IN SOME EXCESSIVE RAINFALL
CONCERNS LATE IN THE PERIOD.

AVIATION
(12Z TAF ISSUANCE)
ISSUED AT 525 AM CDT TUE JUN 9 2026
A MIXED BAG OF IFR TO VFR CONDITIONS AS LOW CEILINGS AND EVEN
ISOLATED SPOTS OF PATCHY FOG CREATING REDUCED VISIBILITIES PREVAIL
EARLY THIS MORNING. CEILINGS ARE MAINLY AN ISSUE FOR THE NORTHERN
TERMINALS, BUT WILL LIFT TO VFR AREAWIDE LATER THIS MORNING.
ISOLATED SH/TS ARE EXPECTED TO DEVELOP NEAR THE COAST ALONG THE
SEA BREEZE AROUND 16Z AND DRIFT NORTHWARD. NOT ENOUGH CONFIDENCE
ON THUNDERSTORM DEVELOPMENT, SO ONLY HAVE PROB30'S FOR SHRA FOR
MOST OF TERMINALS IN THE LATE MORNING TO EARLY AFTERNOON HOURS.
ANY SH/TS THAT DEVELOP WILL DISSIPATE BY 00Z WITH MVFR CEILINGS
FILTERING IN AGAIN OVERNIGHT INTO WEDNESDAY MORNING. SOME
INTERMITTENT IFR CEILINGS ARE POSSIBLE AS WELL FOR THE NORTHERN
TERMINALS (CXO AND NORTHWARD). WINDS WILL BE SOUTHEASTERLY
THROUGHOUT THE TAF PERIOD WITH WIND SPEEDS INCREASING TO 8-12 KT
IN THE AFTERNOON AND TRENDING LIGHTER AFTER SUNSET.

NEARSHORE AND 3 TO 5 FEET OFFSHORE. SLIGHT CHANCE OF SHOWERS AND
THUNDERSTORMS CAN BE EXPECTED DAILY, WITH INCREASING CHANCES
EXPECTED DURING THE UPCOMING WEEKEND. THERE WILL ALSO BE A
