SHOWERS AND THUNDERSTORMS WILL BECOME MORE NUMEROUS AS THE AFTERNOON GOES ON BUT RAIN CHANCES SHOULD DECREASE TO 30 PERCENT AFTER 8 PM AS SUN BEGINS TO SET. STEEP LOW LEVEL LAPSE RATES AND MOIST ATMOSPHERE MAY LEAD TO ISOLATED WET MICROBURTS WITH DAMAGING WIND. SURFACE HIGH PRESSURE RIDGE AXIS TO MOVE NORTH OVERNIGHT WITH EASTERLY LOW LEVEL FLOW THROUGH TUESDAY. EASTERLY LOW LEVEL FLOW FAVORS HIGHEST CHANCES OF RAIN ALONG THE GULF COAST COUNTIES WITH LESSER CHANCES FOR INLAND COUNTIES. TROPICAL WAVE OVER HISPANIOLA IS FORECAST TO MOVE WESTWARD AND REMAIN SOUTH OF FLORIDA. HIGH PRESSURE RIDGE CENTERED OVER EAST TEXAS WILL EXPAND EASTWARD INTO THE ATLANTIC THE NEXT TWO DAYS.
