DISCUSSION

DEEP SOUTH TEXAS WILL REMAIN IN AN UNSETTLED WEATHER PATTERN
THROUGHOUT THE WEEK, AS WEAK DISTURBANCES TRANSLATE ALONG THE
EASTERN PERIPHERY OF RIDGING ALOFT AND INTERACT WITH FAVORABLE
MOISTURE CONTENT AND THE SEA BREEZE. THIS WILL RESULT IN DAILY LOW
TO MEDIUM (20-60%) PRECIPITATION CHANCES, WITH THE BEST CHANCES
ON WEDNESDAY AND THURSDAY AS COASTAL TROUGHING PERSISTS AND
PRECIPITABLE WATER VALUES RISE NEAR OR ABOVE 2 INCHES. THE BEST
TIMING FOR ANY SHOWERS OR THUNDERSTORMS WILL COINCIDE WITH DAYTIME
HEATING, MAINLY LATE MORNING INTO LATE AFTERNOON HOURS, BUT GIVEN
THE SET UP, ISOLATED TO SCATTERED ACTIVITY OVER THE GULF WATERS
AND IMMEDIATE COAST DURING THE OVERNIGHT AND EARLY MORNING HOURS
CANNOT BE RULED OUT AS WELL. THE MAIN THREATS WITH ANY ACTIVITY
ARE GUSTY WINDS, LOCALLY HEAVY RAINFALL, AND LIGHTNING.
OTHERWISE, HIGHS WILL BE NEAR NORMAL FOR MID SEPTEMBER, MOSTLY IN
THE LOW TO MID 90S. INCREASED CLOUD COVER ASSOCIATED WITH ANY
SHOWERS OR THUNDERSTORMS MAY HELP WITH THE HEAT, AT LEAST BRIEFLY.
ALONG THE LOWER TEXAS BEACHES, A MODERATE RISK OF RIP CURRENTS IS
EXPECTED TO CONTINUE THROUGH AT LEAST TUESDAY EVENING DUE TO
PERSISTENT EASTERLY FLOW ACROSS THE GULF WATERS.

GENERALLY FAVORABLE MARINE CONDITIONS WITH LOW TO MODERATE SEAS
AND LIGHT TO MODERATE WINDS WILL CONTINUE THROUGH THE WEEK. EXPECT
DAILY LOW TO MEDIUM (30-60%) RAIN CHANCES OVER THE GULF WATERS
AND LAGUNA MADRE THROUGHOUT THE WEEK. ISOLATED SHOWERS AND
