KEY MESSAGES
- TYPICAL ISOLATED TO WIDELY SCATTERED DAYTIME SHOWER ACTIVITY CAN
BE EXPECTED THROUGHOUT THE WEEK AS WE REMAIN UNDER AN UPPER
LEVEL RIDGE.
- HOT AND HUMID CONDITIONS WILL ALSO CONTINUE WITH AFTERNOON APPARENT
TEMPERATURES OR THE HEAT INDEX BETWEEN 100 AND 105 EACH DAY
WITH MODERATE HEAT RISK.
- THE RIDGE IS EXPECTED TO BREAK DOWN EARLY NEXT WEEK AS A FRONT
APPROACHES INCREASING RAIN CHANCES.
DISCUSSION
(TODAY THROUGH TUESDAY)

LARGE AREA OF UPPER HIGH PRESSURE RIDGING COVERS THE SOUTHEAST US
BY A WIDE MARGIN. ANOMALOUSLY HUMID AIRMASS REMAINS IN PLACE, AND
BENEATH THIS HIGH, IT'S VERY WARM, VERY HUMID AND RATHER MISERABLE
OUTSIDE. SO IT GOES FOR THE FIRST WEEK OF METEOROLOGICAL SUMMER!
LITTLE CHANGE WILL BE HAD OVER THE COMING DAYS AS THE PATTERN IS
RATHER STAGNANT. SOME VARIATIONS TO THE RIDGE OVER THE COMING DAYS
SHOULD RESULT IN 10 TO 20 PERCENT CHANCE OF AFTERNOON SHOWERS (AN
ISOLATED THUNDERSTORM CANNOT BE RULED OUT.) BUT LARGELY, THE NEXT
WEEK WILL BE A WASH-RINSE-AND REPEAT KIND OF FORECAST. EACH DAY
WILL SEE TEMPS IN THE 90S, AND WITH DAILY RH VALUES AROUND 60
PERCENT, THAT HEAT INDEX WILL STILL COME INTO THE LOW 100S TO AS
HIGH AS 108F FOR INLAND AREAS (WHERE HIGH TEMPS WILL SQUEAK INTO
THE LOW TO MID 90S).
THE LONGER WE GO INTO A HEAT WAVE LIKE THIS, THE MORE THE HEAT
STRESS ACTS ON THE BODY. MAINTAIN GOOD HEAT SAFETY AS MUCH AS
POSSIBLE EACH AND EVERY DAY: HYDRATE, TAKE FREQUENT BREAKS, CHECK
ON THOSE VULNERABLE GROUPS AROUND YOU.
AS FOR RAIN CHANCES, THERE ARE SOME LOW END POPS FROM TOMORROW TO
THE END OF THE WEEK. THIS IS TO ACCOUNT FOR THE SEABREEZE SHOWERS
WHICH CAN MAKE THEIR WAY UP AND PAST THE RIDGING. AS THE HIGH
MEANDERS AROUND, THERE COULD BE POCKETS OF DAYTIME SHOWERS/ISO
STORMS TO POP UP LATER IN THE DAY. THE SUMMERTIME NORMAL.

AVIATION
(18Z TAFS)
ISSUED AT 1216 PM CDT WED JUN 10 2026
PLENTY OF LOW LEVEL GULF MOISTURE MOVING ACROSS THE FORECAST AREA
FROM THE SOUTH FLOW. DAYTIME HEATING HAS ALLOWED STREAKS OF CU
WITH OCCASIONAL MVFR CEILINGS. NOT EXPECTING MUCH IN THE WAY OF
SHOWER ACTIVITY WITH AN UPPER LEVEL RIDGE OVERHEAD, DID MENTION
SOME VCSH FOR KBPT.
LOW CLOUDS AND ANY SHOWERS WILL DISSIPATE WITH SUNSET.
OVERNIGHT, SOME LOW CLOUDS AND PATCHY FOR MAY FORM NEAR SUNRISE,
WITH THE BEST PROBABILITY OF THIS OCCURRING IS AT THE KAEX
TERMINAL.
07/RUA
MARINE
ISSUED AT 1215 AM CDT WED JUN 10 2026
HIGH PRESSURE RIDGE WILL PERSIST OVER THE NORTHEAST GULF DURING
THE PERIOD BRINING ABOUT A PROLONGED PERIOD OF LIGHT TO BREEZY
ONSHORE FLOW, LOW SEAS AND MOSTLY CLEAR CONDITIONS.
THE RIDGE STARTS TO ERODE SLIGHTLY INTO THE END OF THE WORK WEEK
WHICH COULD HELP BRING SOME LOW END RAIN CHANCES BACK TO THE
NEARSHORE WATERS.
FIRE WEATHER
ISSUED AT 1215 AM CDT WED JUN 10 2026
ANOMALOUSLY WARM AND HUMID CONDITIONS WILL PERSIST OVER THE COMING
DAYS WITH ONLY LOW TO OCCASIONALLY BREEZY SOUTH WINDS TO OFFER
SOME REPRIEVE. HIGH PRESSURE SETTLED ON TOP OF THE NORTHEAST GULF
WILL KEEP MAJORITY OF RAIN CHANCES FROM THE FORECAST, BUT
AFTERNOON SEABREEZE SHOWERS WITH AN ISOLATED STORM OR TWO WILL BE
POSSIBLE NEAR THE COASTAL AREAS.
