KEY MESSAGES
ISSUED AT 1207 AM CDT THU SEP 11 2025
- SUMMER-LIKE TEMPERATURES RETURN THROUGH THE WEEKEND WITH HIGH
TEMPERATURES MAINLY IN THE MID-90S WITH ISOLATED READINGS
REACHING THE UPPER 90S.
- ISOLATED TO SCATTERED SHOWERS AND STORMS ARE POSSIBLE NEAR THE
COAST THROUGH THURSDAY NIGHT.
DISCUSSION
ISSUED AT 1207 AM CDT THU SEP 11 2025
AN UPPER LEVEL RIDGE WILL REMAIN DOMINATE OVER TEXAS THROUGH THE
WEEKEND HELPING TO BRING A RETURN TO HOTTER, MORE HUMID,
CONDITIONS. WIDESPREAD HIGH TEMPERATURES IN THE LOW TO MID 90S ARE
EXPECTED WITH ISOLATED SPOTS CLIMBING INTO THE UPPER 90S THROUGH
THE WEEKEND THANKS TO INCREASED HEIGHTS AND ABUNDANT SUNSHINE. THE
RIDGE BEGINS TO BREAK DOWN AT THE START OF NEXT WEEK LEADING TO
DAYTIME TEMPERATURES DROPPING BACK DOWN A FEW DEGREES. PERSISTENT
EASTERLY FLOW WILL BRING INCREASED MOISTURE TO THE REGION (PWATS
UP TO AROUND 1.6-1.8", AND DEW POINTS BACK INTO THE UPPER 60S TO
LOW 70S) LEADING TO AFTERNOON PEAK HEAT INDICES TO NEAR 100
DEGREES. OVERNIGHT LOWS WILL GENERALLY STAY IN THE LOW TO MID 70S
FOR MUCH OF THE REGION WITH TEMPERATURES NOT DROPPING BELOW 80
DEGREES AT THE COAST.
DESPITE THE HIGH PRESSURE BUILDING INTO THE REGION, THERE WILL BE
A CHANCE OF ISOLATED COASTAL SHOWERS THURSDAY MORNING/EARLY
AFTERNOON THANKS TO INCREASING PWATS. THE MAJORITY OF THE ACTIVITY
WILL REMAIN OVER THE COASTAL WATERS, BUT SOME ISOLATED SHOWERS
COULD MOVE INLAND AT TIMES. THE BEST CHANCES OVER LAND WILL BE
DOWN NEAR MATAGORDA BAY (SUCH AS JACKSON, MATAGORDA, AND WALKER
COUNTIES), BUT THERE WILL BE AT LEAST A SLIGHT CHANCE OF AN
ISOLATED SHOWER UP THE SE TEXAS COAST. THOSE LOCATED NORTH OF I-10
WILL LIKELY SEE NO RAINFALL ON THURSDAY (AND LIKELY THROUGH THE
REMAINDER OF THE FORECAST PERIOD). AS THE HIGH PRESSURE MOVES
CLOSER TO SE TEXAS BY FRIDAY AND REMAINING OVERHEAD OVER THE
WEEKEND, THE CHANCE FOR PRECIPITATION WILL BE MINIMAL WITH JUST AN
ISOLATED NOCTURNAL SHOWER POSSIBLE OVER THE GULF WATERS. AS THE
HIGH PRESSURE BEGINS TO BREAK DOWN AT THE START OF NEXT WEEK,
CHANCES OF AT LEAST ISOLATED COASTAL SHOWERS BEGINS TO INCREASE.
