DISCUSSION
ISSUED AT 1211 PM CDT TUE JUN 9 2026
WARM, HUMID, AND RAIN-FREE CONDITIONS SHOULD PERSIST THROUGH DEEP
SOUTH TEXAS THROUGH THURSDAY EVENING AS UPPER LEVEL RIDGING REMAINS
DOMINANT OVER THE SOUTH CENTRAL PLAINS. AS A RESULT, HEAT RISK WILL
BE A CONCERN OVER THE NEXT SEVERAL DAYS. MODERATE (LEVEL 2 OF 4)
HEAT RISK IS EXPECTED THROUGHOUT ALL OF DEEP SOUTH TEXAS ALL WEEK,
THROUGH THE WEEKEND, AND INTO EARLY NEXT WEEK AS WELL.
RAIN CHANCES WILL BEGIN TO INCREASE ON FRIDAY AS AN INFLUX OF GULF
MOISTURE IS EXPECTED TO ARRIVE TO DEEP SOUTH TEXAS FROM THE SOUTH.
THIS INFLUX OF MOISTURE WILL ACCOMPANY SURFACE TROUGHING JUST TO OUR
SOUTH-SOUTHEAST THAT WILL ALLOW FOR LOW (10-30%) RAIN CHANCES
FRIDAY, INCREASING TO LOW TO MODERATE (20-40%) FOR SATURDAY. SUNDAY
THROUGH TUESDAY WILL ALSO SUPPORT LOW TO MODERATE CHANCES (10-40%
WITH THE BEST CHANCES ON TUESDAY) AS THE ATMOSPHERE CONTINUES TO
REMAIN UNSETTLED. PWATS ARE EXPECTED TO REMAIN UNUSUALLY HIGH (OVER
2 INCHES), SO SHOWERS AND ANY THUNDERSTORMS THAT HAPPEN TO FORM WILL
BE EFFICIENT RAINMAKERS. AT THIS TIME, NO SIGNIFICANT ACCUMULATION
OR FLOOD THREATS ARE EXPECTED, BUT WE WILL CONTINUE TO MONITOR.
A MODERATE RISK OF RIP CURRENTS WILL PERSIST AT AREA BEACHES THROUGH
AT LEAST TOMORROW AFTERNOON.
