THE FORECAST CONTINUES TO TREND A BIT WETTER, AT LEAST THROUGH
THE WEEKEND. AN INVERTED MID-LEVEL TROUGH OF LOW PRESSURE WILL
RETROGRADE WEST FROM THE WESTERN GULF OF AMERICA INTO NORTHEAST
MEXICO, WHERE IT WILL THEN LINGER AND TRANSITION INTO A BROAD 500
MB LOW. COMBINED WITH PRECIPITABLE WATER (PWAT) VALUES THAT WILL
HOVER AROUND TWO INCHES AND DAYTIME HEATING, THE RESULT WILL BE
THE RISK FOR ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS FOR
WEDNESDAY THROUGH SUNDAY, WITH THE LEAST CHANCE OF RAIN OCCURRING
THURSDAY, AND THE GREATEST CHANCE OF PRECIPITATION PROJECTED FOR
SATURDAY. AFTER THE WEEKEND, WITH THE DISSIPATION OF THE 500 MB
LOW, MID-LEVEL HIGH PRESSURE BUILDING-IN FROM THE EAST, AND PWAT
VALUES DECREASING TO AROUND 1.5 INCHES, DRY WEATHER WILL RETURN.
TEMPERATURE-WISE, NO REAL EXTREME VALUES ARE ANTICIPATED, WITH
NEAR NORMAL HIGHS INCHING-UP TO SLIGHTLY ABOVE NORMAL LEVELS AT
THE START OF THE NEW WORK WEEK AS THE MID-LEVEL HIGH INCREASES ITS
INFLUENCE ON DEEP SOUTH TEXAS AND THE RIO GRANDE VALLEY.
