AN UNSETTLED WEATHER PATTERN CONTINUES ACROSS DEEP SOUTH TEXAS.
DAYTIME HEATING IN COMBINATION WITH ABUNDANT TROPICAL MOISTURE
AND A SERIES OF DISTURBANCES PASSING OVERHEAD WILL KEEP RAIN AND
THUNDERSTORM CHANCES IN THE FORECAST THROUGH MID-WEEK. THE RAIN
CHANCES WILL TYPICALLY REMAIN HIGHEST (30-60%) ALONG AND EAST OF
US 281/I-69C. MUCH OF THIS ACTIVITY WILL BE ALONG THE SEABREEZE,
WITH PEAK TIMING FOR PRECIPITATION IN THE EARLY AFTERNOON INTO THE
EARLY EVENING.
INCREASED CLOUD COVER AND RAIN CHANCES, PRIMARILY DURING PEAK
AFTERNOON HEATING, WILL KEEP TEMPERATURES NEAR NORMAL THROUGH MID-
WEEK.
ONSHORE FLOW AND SLIGHTLY ELEVATED SEAS WILL MAINTAIN A MODERATE
RISK OF RIP CURRENTS ALONG THE BEACHES OF THE LOWER TEXAS COAST
THROUGH THURSDAY.
