DISCUSSION
ISSUED AT 1015 PM CDT FRI AUG 8 2025
MID-LEVEL HIGH PRESSURE OVER THE DESERT SOUTHWEST AND ACROSS THE
SOUTHEASTERN US INTO THE EASTERN GULF WILL CONTINUE INTO NEXT WEEK.
AT THE SAME TIME TROUGHING AND ALONG THE LOWER TEXAS COAST WILL
ALLOW DAILY CHANCES OF SHOWERS AND THUNDERSTORMS (20-35%), MAINLY
ALONG THE SEA BREEZE THROUGH WEDNESDAY. WILL SEE LESSER CHANCES (10%
OR LESS) OF PRECIPITATION AS WE HEAD TOWARDS THE END OF NEXT WEEK
AS MID LEVEL RIDGING SPREADS WESTWARD INTO DEEP SOUTH TEXAS.
NEAR TO SLIGHTLY ABOVE NORMAL TEMPS WILL CONTINUE INTO NEXT WEEK,
WITH HEAT INDICES OF 105 TO 110 DEGREES EACH DAY. A FEW LOCATIONS,
ESPECIALLY ACROSS THE INLAND COASTAL COUNTIES, MAY BRIEFLY HAVE HEAT
INDICES EXCEED 110 DEGREES ESPECIALLY AS WE HEAD INTO MID TO LATE
WEEK. THE TIMEFRAME AND COVERAGE REMAINS BELOW HEAT ADVISORY
CRITERIA BUT CAN NOT RULE OUT THE POSSIBILITY OF A HEAT ADVISORY
BEING NEEDED WEDNESDAY, THURSDAY AND/OR FRIDAY. AT THE VERY LEAST,
SPSS WILL LIKELY BE NEEDED. HEAT RISK WILL REMAIN MODERATE (LEVEL 2
OF 4) TO MAJOR (LEVEL 3 OF 4) EVERY DAY.
AVIATION
(18Z TAFS)
ISSUED AT 1212 PM CDT SAT AUG 9 2025
VFR CONDITIONS ARE EXPECTED TO PERSIST THROUGH THE TAF CYCLE WITH
MODERATE (10-15 KNOTS) SOUTHEASTERLY WINDS BECOMING GENTLE
FOLLOWING SUNSET AND THEN LIGHT AND VARIABLE OVERNIGHT TONIGHT.
THERE IS A LOW (LESS THAN 15%) CHANCE OF AN ISOLATED SHOWER OR
THUNDERSTORM INTO THE REST OF THIS AFTERNOON, WHICH COULD BRIEFLY
LOWER CEILINGS TO MVFR, BUT THE PROBABILITY IS TOO LOW TO INCLUDE
IN THE TAF. OTHERWISE, MODERATE SOUTHEASTERLY WINDS PICK UP AGAIN
LATE SUNDAY MORNING INTO THE EARLY AFTERNOON HOURS.
MARINE
ISSUED AT 1015 PM CDT FRI AUG 8 2025
GENERALLY FAVORABLE MARINE CONDITIONS WILL PREVAIL ON THE WATERS OFF
THE LOWER TEXAS COAST. WAVE HEIGHTS WILL REMAIN AT 1 TO 2 FEET WITH
4 TO 6 SECOND PERIODS. ISOLATED SHOWERS AND THUNDERSTORMS EACH DAY
COULD LEAD TO LOCALIZED AREAS OF ELEVATED WINDS AND SEAS.
