KEY MESSAGES
ISSUED AT 1208 PM CDT SUN AUG 10 2025
- MOSTLY TYPICAL SUMMERTIME WEATHER IS EXPECTED THIS WEEK WITH
HOT/HUMID CONDITIONS AND ISOLATED TO SCATTERED SHOWERS AND
THUNDERSTORMS EACH DAY.
- RAIN CHANCES WILL VARY ON A DAY-TO-DAY BASIS DEPENDING ON
MOISTURE LEVEL FLUCTUATIONS, BUT MODEL GUIDANCE IS CURRENTLY
SUGGESTING THAT WE MIGHT SEE THAT FRIDAY HAS THE BEST OVERALL
PRECIP CHANCES/COVERAGE.
DISCUSSION

WATER VAPOR IMAGERY SHOWS THE INVERTED MID-UPPER HAS MADE IT TO THE
TX COAST. ITS AXIS SHOULD VERY SLOWLY DRIFT WESTWARD THE NEXT FEW
DAYS AND LEAVE A GENERAL WEAKNESS ACROSS THE REGION (SANDWICHED
BETWEEN RIDGES TO THE WEST/EAST) INTO MID-LATE WEEK. PW'S AREN'T
FCST TO BE VERY HIGH, JUST IN THE 1.6-2.1" RANGE INTO TUESDAY...BUT
STILL ENOUGH TO GET SOME TYPICAL DIURNALLY DRIVEN ISOLATED TO
SCATTERED SHOWERS AND THUNDERSTORMS TO EMERGE.
WED-FRI, WE SHOULD SEE DEEPER GULF MOISTURE, CURRENTLY SITUATED IN
THE EASTERN GULF AND CARIBBEAN (2.0-2.5") MAKES ITS WAY TOWARD AND
INTO THE AREA WHICH SHOULD ALLOW FOR SLIGHTLY HIGHER AREAL COVERAGE
THAN WHAT WE SEE IN THE FIRST HALF OF THE WORK WEEK. HIGHEST SURGE
LOOKS TO ARRIVE AROUND FRIDAY.
HEADING INTO THE WEEKEND, RIDGING WILL BUILD WESTWARD ACROSS THE
NORTHERN GULF AND INTO THE AREA. WITH RISING HEIGHTS, MORE
SUBSIDENCE AND LOWER MOISTURE AVAILABILITY...RAIN CHANCES SHOULD
TREND DOWNWARD AND TEMPERATURES UPWARD. 47
AVIATION
(12Z TAF ISSUANCE)
ISSUED AT 634 AM CDT SUN AUG 10 2025
PRETTY CLOSE TO A PERSISTENCE FORECAST FOR TODAY. VCSH ALREADY
BEING SEEN AT LBX AND SOMETIMES GLS, AND WILL TRANSITION TO AFTN
TSRA A FARTHER INLAND. PROB30S FOR SGR, HOU, AND IAH AGAIN WITH A
SLIGHT FAVOR TO THE SOUTHERN PAIR VERSUS IAH. OPTED TO INCLUDE
GUSTY WINDS IN THE PROB30 TODAY AS ENVIRONMENT IS QUITE SIMILAR TO
YESTERDAY, WHICH PRODUCED NUMEROUS 20-30 KT GUSTS AND A FEW IN
EXCESS OF 30 KT. IF PRO20 OR PROB15 WERE AN ALLOWABLE MENTION,
WOULD USE THAT FOR CXO...SO EVEN THOUGH IT HAS NO PRECIP MENTION
FOR THE AFTERNOON, -TSRA NOT COMPLETELY OFF THE TABLE THERE EITHER.
MARINE
ISSUED AT 1207 PM CDT SUN AUG 10 2025
WITH THE EXCEPTION OF THE AFTERNOON-EVENING SEABREEZE WHEN WE'LL SEE
WINDS IN THE 10-15KT RANGE, LIGHT WINDS AND LOW SEAS LOOK TO
CONTINUE INTO MIDWEEK. A MORE PREVAILING SSE WIND 8-15KT SHOULD SET
UP DURING THE SECOND PART OF THE WEEK ALLOWING FOR SOME SLIGHTLY
HIGHER SEAS IN THE 3-4FT RANGE TAKE SHAPE. MARINERS SHOULD
ANTICIPATE SCATTERED SHOWERS AND THUNDERSTORMS EACH DAY - WITH THE
HIGHEST CHANCES GENERALLY IN THE LATE NIGHT THROUGH EARLY
AFTERNOON HOURS. 47
