KEY MESSAGES
- AN UPPER LEVEL RIDGE WILL BUILD IN THROUGH THE BEGINNING OF THE
WEEK HELPING TO REDUCE SHOWER ACTIVITY TO THE MORE TYPICAL
ISOLATED TO WIDELY SCATTERED COVERAGE DURING THE AFTERNOON.
- CONDITIONS WILL BECOME HOTTER AND MORE HUMID LATER IN THE WEEK
WITH AFTERNOON HEAT INDEX VALUES REACHING BETWEEN 100 AND 109
DEGREES.
- HEAT RISK AND STRESS ON THE BODY WILL COMPOUND WITH EACH DAY.
MAKE SURE TO MAINTAIN GOOD HEAT SAFETY. CHECK ON OTHERS, HYDRATE
AND TAKE FREQUENT BREAKS.
DISCUSSION
(TODAY THROUGH MONDAY)
ISSUED AT 1221 AM CDT TUE JUN 9 2026
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
(06Z TAFS)
ISSUED AT 1221 AM CDT TUE JUN 9 2026
VFR CONDITIONS WITH LIGHT SOUTHEASTERLY WINDS WILL PREVAIL ACROSS
THE AREA TONIGHT. SOME PATCHY LIGHT FOG/MIST MAY DEVELOP AT TIMES
TONIGHT, MORE LIKELY AT AEX, BUT ANY FOG THAT DEVELOPS WILL
DISSIPATE QUICKLY WITH SUNRISE. ISOLATED CONVECTION WILL BE POSSIBLE
ALONG THE SEABREEZE BOUNDARY, WHICH COULD BRING A SHOWER OR
THUNDERSTORM TO BPT/LCH/LFT/ARA IN THE AFTERNOON, BUT CONFIDENCE IS
TOO LOW TO INCLUDE IN THE TAFS AT THIS TIME. OUTSIDE OF STORMS, 5-10
KT SOUTHEAST WINDS AND VFR CONDITIONS ARE EXPECTED FOR ALL SITES
THROUGH THE REMAINDER OF THE FORECAST PERIOD.
64/SILAS
MARINE
ISSUED AT 1221 AM CDT TUE JUN 9 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 1221 AM CDT TUE JUN 9 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.
