DISCUSSION
ISSUED AT 1206 PM CDT SAT AUG 30 2025
WE ARE ALL EXCITED ABOUT THE PROSPECT OF THE UPCOMING RAIN, BUT WE
NEED TO PAY ATTENTION TO THE POTENTIAL FOR HEAT RELATED IMPACTS
SUNDAY. HIGHS WILL CONTINUE TO REACH INTO THE UPPER 90S TO LOW
100S, WITH HEAT INDEX VALUES BETWEEN 105-112 IN THE AFTERNOON.
THOSE IN THE BRUSH COUNTRY SHOULD BE ESPECIALLY CAUTIOUS WHEN
WORKING OR PLAYING OUTSIDE AS A MAJOR TO EXTREME (LEVELS 3-4 OF 4)
HEAT RISK IS ANTICIPATED. WITH MANY RESIDENTS LIKELY OUTDOORS FOR
THE LABOR DAY WEEKEND, PRACTICING HEAT SAFETY WILL BE CRITICAL.
PLEASE REMEMBER TO STAY HYDRATED, TAKE FREQUENT BREAKS, AND AVOID
PROLONGED DIRECT SUN EXPOSURE. ADDITIONAL SAFETY TIPS ARE
AVAILABLE AT WEATHER.GOV/HEAT.
BY SUNDAY, THE RIDGE WILL MOVE TO THE WEST WITH A SHORTWAVE RIDING
ALONG THE EASTERN PERIPHERY. THIS WILL COMBINE WITH ABUNDANT
MOISTURE (PWAT VALUES REACHING 2+ INCHES) AND A STALLED BOUNDARY
OVER THE AREA TO BRING US SOME OF THE RAIN WE DESPERATELY NEED.
A LOW TO MEDIUM (20-70%) CHANCE OF SHOWERS AND THUNDERSTORMS WILL
DEVELOP LATE SUNDAY AND CONTINUE THROUGH TUESDAY MORNING. ONCE
AGAIN, GUIDANCE IS STILL UNCLEAR ON HOW FAR SOUTH THE MOISTURE
WILL MAKE IT INTO THE AREA, SO HAVE CONTINUED TO LOWER POPS JUST A
BIT FOR SUNDAY AND EVEN INTO MONDAY. EVEN SO, EXPECT THAT THERE
COULD BE HIGH RAINFALL RATES AT TIMES WHICH COULD LEAD TO ISOLATED
FLASH FLOODING. WPC HAS MAINTAINED A MARGINAL RISK OF EXCESSIVE
RAINFALL OVER THE NORTHERN TIER OF COUNTIES ON SUNDAY/SUNDAY
NIGHT, THEN EXPANDED THIS TO COVER MOST OF SOUTH TEXAS FOR
MONDAY/MONDAY NIGHT. RAIN CHANCES WILL DIMINISH BY TUESDAY AS THE
STALLED BOUNDARY MOVES ACROSS THE AREA BRINGING DRIER AIR.
AVIATION
(18Z TAFS)
ISSUED AT 1206 PM CDT SAT AUG 30 2025
VFR CONDITIONS WILL CONTINUE THROUGH THE FORECAST PERIOD, THOUGH
BRIEF MVFR CEILINGS ARE POSSIBLE FOR ALI BETWEEN 11Z-15Z. A LOW
CHANCE FOR SHOWERS AND THUNDERSTORMS STORMS REMAINS AT VCT
TERMINAL, BUT THIS IS STILL TOO LOW TO INCLUDE IN TAFS. MODERATE
SOUTHEASTERLY WINDS WILL DEVELOP BEHIND THE AFTERNOON SEA BREEZE,
THEN DIMINISH INTO THE OVERNIGHT HOURS.
MARINE
ISSUED AT 1206 PM CDT SAT AUG 30 2025
GENTLE TO MODERATE (BF 3-4) ONSHORE FLOW WITH OCCASIONALLY FRESH
(BF 5) BREEZES ALONG THE SOUTHERN BAYS AND NEARSHORE WATERS WILL
CONTINUE THROUGH THE WEEKEND. RAIN CHANCES WILL BECOME LOW TO
MEDIUM (20-70%) LATE SUNDAY THROUGH EARLY TUESDAY AFTERNOON
BEFORE DIMINISHING AS A BOUNDARY MOVES SOUTH THROUGH THE WATERS.
THE BOUNDARY PASSAGE WILL SHIFT WINDS TO THE NORTH AND BRING IN
DRIER AIR. ONSHORE FLOW WILL RETURN BY WEDNESDAY.
