DISCUSSION
ISSUED AT 1211 PM CDT THU JUL 17 2025
A GENERALLY HOT AND RAIN-FREE PERIOD FOR DEEP SOUTH TEXAS AND THE
RIO GRANDE VALLEY. UPPER-LEVEL HIGH PRESSURE WILL CONTINUE TO BE THE
BIGGEST INFLUENCE FOR THE WEATHER OVER THE REGION ALLOWING FOR MORE
SUBSIDENCE TO OCCUR AND THUS LIMITING CHANCES FOR RAIN. WHILE A
STRAY SHOWER OR THUNDERSTORM WITH THE SEABREEZE CANNOT BE RULED OUT
FOR THE PERIOD, THE CHANCES FOR RAIN ARE VERY LOW (LESS THAN 10%).
MOSTLY SUNNY SKIES ARE EXPECTED FOR THE PERIOD ALLOWING FOR
TEMPERATURES TO RISE AS WELL. THE HIGH TEMPERATURES ARE EXPECTED TO
GENERALLY RANGE FROM THE MID 90S TO THE LOWER TRIPLE DIGITS.
HOWEVER, THE HEAT INDICES AT THIS TIME ARE EXPECTED TO ONLY RANGE
FROM 105-108. WHILE THAT IS BELOW THE CRITERIA FOR HEAT ADVISORY. IT
IS STILL A GOOD IDEA TO PRACTICE HEAT SAFETY AND LIMIT TIME OUTSIDE
ESPECIALLY DURING PEAK HEATING HOURS. THE HEAT RISK FOR THE PERIOD
IS MOSTLY MODERATE (LEVEL 2 OF 4). THE LOW TEMPERATURES FOR THE
PERIOD ARE MOSTLY IN THE 70S, WITH A FEW PLACES ON THE EXTREME
SOUTHERN PORTIONS OF THE CWA APPROACHING 80.
THE NATIONAL HURRICANE CENTER CONTINUES TO MONITOR AN AREA OF LOW
PRESSURE OVER THE COAST OF MISSISSIPPI AND CURRENTLY HAS ABOUT 30%
CHANCE OF DEVELOPMENT. REGARDLESS OF DEVELOPMENT, THIS SYSTEM IS NOT
EXPECTED TO HAVE MANY IMPACTS TO THE REGION. HOWEVER, SOME INCREASE
IN SWELL AND RIP CURRENT RISK IS POSSIBLE IF ANY DEVELOPMENT DOES
OCCUR. HOWEVER THE CURRENT FORECAST KEEPS SWELL AND RIP CURRENT RISK
LOW ALONG THE LOWER TEXAS COAST.

EXERCISE CAUTION FOR SHORT PERIODS OF TIME STARTING THIS WEEKEND AND
