SOME STORMS WERE A BIT STRONGER...WITH EMBEDDED SMALL HAIL POSSIBLE...AND SOME RESULTED IN PERIODS OF MODERATE TO HEAVY RAINFALL DUE TO SLOWER MOVEMENT AND DEEP MOISTURE...BUT SEVERE WAS NOT IN THE CARDS AS OF YET...AND HEAVIER RAINS SEEMED SHY OF ANY SERIOUS LOCAL FLOODING.

WITH WARM TEMPERATURES PERSISTING OVER THE AREA...COMBINED WITH HIGH ENOUGH RELATIVE HUMIDITIES...THE HEAT INDICES WILL CONTINUE TO AVERAGE FROM 100 TO 110 DEGREES IN THE PEAK OF THE AFTERNOON EACH DAY THROUGH THE EXTENDED. A COUPLE OF THE MODELS HINT AT THE POSSIBILITY OF ANOTHER AREA OF LOW PRESSURE MOVING INTO THE WESTERN GULF OF MEXICO SOMETIME DURING THE MIDDLE OF NEXT WEEK. THIS COULD BRING ANOTHER SHOT AT RAIN TO PORTIONS OF DEEP SOUTH TEXAS IF IT PANS OUT.

FRIDAY THROUGH TUESDAY...A RIDGE OF HIGH PRESSURE WILL BEGIN TO BUILD BACK OVER THE LOWER TEXAS COASTAL WATERS FOR FRIDAY AND MOVING INTO THE WEEKEND. WHILE THERE WILL CONTINUE TO BE SOME SMALL CHANCES OF LINGERING SHOWERS ON FRIDAY...THIS HIGH PRESSURE WILL ALLOW FOR DRY CONDITIONS TO RETURN FOR THE WEEKEND AND INTO EARLY NEXT WEEK.
