DISCUSSION
ISSUED AT 1047 PM CDT THU JUL 17 2025
GENERALLY HOT AND DRY CONDITIONS ARE EXPECTED TO CONTINUE ACROSS
DEEP SOUTH TEXAS THROUGH THE FORECAST. A COUPLE BRIEF SHOWERS
ALONG THE AFTERNOON SEA BREEZE CAN'T BE RULED OUT, HOWEVER RAIN
CHANCES REMAIN BELOW 10%. PERSISTENT UPPER LEVEL HIGH PRESSURE
WILL CONTINUE TO PROVIDE BROAD SUBSIDENCE ACROSS SOUTHERN TEXAS.
THIS PATTERN WILL LIKELY SUPPORT MOSTLY SUNNY SKIES AND A GRADUAL
INCREASE IN TEMPERATURES THROUGH THE PERIOD. HEAT INDICES LOOK TO
LARGELY REMAIN BETWEEN 105-108 EACH AFTERNOON, WITH THE EXCEPTION
OF MONDAY AND TUESDAY, WHICH COULD SEE HEAT INDICES BRIEFLY
APPROACH 110-112. THE DURATION OF THESE HIGHER HEAT INDICES
LIKELY WON'T BE LONG ENOUGH TO WARRANT A HEAT ADVISORY, HOWEVER A
SPECIAL WEATHER STATEMENT MAY BE NEEDED.
