DISCUSSION
ISSUED AT 1058 PM CDT FRI JUL 18 2025
THERE WERE A FEW SHOWERS AND THUNDERSTORMS THAT DEVELOPED NEAR
THE COAST TODAY PRODUCING LOCALIZED SPOTS OF NEAR 1" OF RAIN, BUT
OTHERWISE MOST OF THE RAINFALL ASSOCIATED WITH THAT DISTURBANCE
WE'VE BEEN MONITORING MISSED US TO THE EAST. SOME LINGERING
TROPICAL MOISTURE AND WEAKNESS ALOFT WILL CONTINUE THROUGH
SATURDAY, SO SOME ADDITIONAL SCATTERED AFTERNOON SHOWERS AND
STORMS WILL BE POSSIBLE GENERALLY EAST OF I-45. HIGH PRESSURE THEN
BUILDS IN ON SUNDAY THAT WILL PERSIST THROUGH AT LEAST WEDNESDAY
PROVIDING US WITH HOT, HUMID, BUT MOSTLY RAIN-FREE WEATHER. THIS
HIGH PRESSURE DOES BEGIN TO SHIFT TO THE NORTH BY THURSDAY OR
FRIDAY WITH A SHORTWAVE SLIDING WESTWARDS ALONG THE SOUTHERN EDGE
OF THE HIGH. AS OF RIGHT NOW, THIS DISTURBANCE WILL BE TAKING A
VERY SIMILAR TRACK AS THE DISTURBANCE WE TRACKED THIS WEEK,
SKIRTING ALONG THE GULF COAST. THIS SYSTEM WILL BE THE NEXT DECENT
CHANCE AT SHOWERS AND THUNDERSTORMS, LIKELY REACHING COASTAL
TEXAS SOMETIME BETWEEN THURSDAY NIGHT AND SATURDAY MORNING.
HIGH TEMPERATURES THROUGH THE WEEKEND WILL BE IN THE LOW TO MID
90S WITH LOWS IN THE MID TO UPPER 70S INLAND AND LOW TO MID 80S
AT THE COAST. TEMPERATURES DO INCREASE BEGINNING MONDAY WITH MOST
OF THE REGION GETTING AT LEAST INTO THE MID 90S WITH SOME ISOLATED
SPOTS INTO THE UPPER 90S. AFTERNOON MAX HEAT INDICES WILL BE IN
THE 103- 107 DEGREE RANGE. THESE CONDITIONS WILL CONTINUE UNTIL
THAT DISTURBANCE APPROACHES FROM THE EAST AT THE END OF THE WEEK.
