A DRIER, MORE COMFORTABLE DAY WITH RH VALUES OF 50-60% IN THE VALLEY
AND HIGH TEMPERATURES IN THE MID-90S. THERE IS A CHANCE FOR AN
ISOLATED SHOWER OR TWO THIS AFTERNOON AS A CORRIDOR OF DECENTLY
MOIST AIR TO OUR SOUTHWEST EXPANDS EAST, AND AS SHOWERS WITHIN ARE
USHERED NORTHWESTWARD. THE GREATEST CHANCE OF RAIN IS STILL LOW, 30%
OR LESS, PRIMARILY IN THE UPPER VALLEY AND RIO GRANDE PLAINS THROUGH
THIS AFTERNOON.
PERSISTENT COASTAL TROUGHING WILL ALLOW MOISTURE TO BUILD, RETURNING
US TO NEAR-NORMAL PWAT VALUES FOR MID-SEPTEMBER. THIS, PAIRED WITH A
TROUGH ACROSS THE CENTRAL US TRANSLATING EAST PROVIDING SHORTWAVE
DISTURBANCES OVER SOUTH TEXAS MIDWEEK, WILL MAINTAIN A DAILY LOW TO
MODERATE CHANCE (30-60%) OF RAIN FOR MUCH OF THE FORECAST. EXPECT A
SIMILAR PATTERN SEEN THIS PAST WEEK, WITH SHOWERS OVER THE GULF IN
THE MORNING WORKING THEIR WAY INLAND THROUGH THE AFTERNOON. THE
GREATEST CHANCES OF RAIN WILL BE EACH AFTERNOON, PRIMARILY ALONG THE
COAST AND RGV. SHOWERS MAY BE BRIEFLY HEAVY, LEADING TO PONDING IN
LOW-LYING, POOR DRAINAGE, AND/OR URBAN AREAS. GUSTY WINDS AND
LIGHTNING ARE ALSO POSSIBLE IN STRONGER STORMS.
AT LOCAL TEXAS BEACHES, PERSISTENT EASTERLY FLOW ACROSS THE GULF HAS
BROUGHT ELEVATED SEAS. INCREASED WAVE HEIGHTS WILL MAINTAIN A
MODERATE RISK OF RIP CURRENTS INTO THE WEEK.
