DISCUSSION

UNSETTLED WILL BE THE THEME THROUGHOUT THE PERIOD. AFTER A
LACKADAISICAL TUESDAY, IN WHICH RELATIVELY LOW PRECIPITABLE WATER
(PW) CONTENT WILL RESULT IN PALTRY RAIN CHANCES, A MORE ACTIVE
WEATHER PATTERN WILL BECOME ESTABLISHED AND PERSIST. THIS WILL BE
DUE TO MORE ROBUST PW VALUES INTERACTING WITH DAYTIME HEATING, THE
EAST-TO-WEST MIGRATION OF THE DAYTIME SEABREEZE BOUNDARY, AND A
SERIES OF DISTURBANCES THAT WILL "RIDGE RIDE" 500 MB HIGH PRESSURE
CENTERED MORE OR LESS OVER NORTHWEST MEXICO.
TEMPERATURE-WISE, THE DAILY THREAT FOR SHOWERS AND THUNDERSTORMS,
ALONG WITH THE ASSOCIATED CLOUD COVER, WILL HAVE A DAMPENING
EFFECT, WITH VALUES MORE NEAR NORMAL FOR THIS TIME OF YEAR.
FINALLY, WITH CONTINUED SLIGHTLY ELEVATED SEAS, A MODERATE RISK OF
RIP CURRENTS IS LIKELY FOR THE BEACHES ALONG THE LOWER TEXAS
COAST.
