DEEP SOUTH TEXAS AND THE RIO GRANDE VALLEY WILL BE UNDER THE
DIRECT INFLUENCE OF 500 MB HIGH PRESSURE, WHICH WILL STEADILY
BUILD NORTHEAST OUT OF NEIGHBORING MEXICO DURING THE PERIOD. THIS
WILL PRODUCE DRY WEATHER ACROSS THE BRO CWFA FOR THE WEEKEND.
MEANWHILE, TEMPERATURE-WISE, RELATIVELY LIMITED CLOUD COVER AND A
BREEZY ONSHORE FLOW WILL ENSURE ABOVE NORMAL DAYTIME HIGHS AND
OVERNIGHT LOWS.
FINALLY, ELEVATED SEAS ALONG THE LOWER TEXAS COAST WILL PRODUCE A
MODERATE RISK OF RIP CURRENTS AT THE LOCAL BEACHES.
