DISCUSSION

PERSISTENCE FORECAST CONTINUES WITH NOT MUCH IN THE WAY OF
MEANINGFUL CHANGES, AS HOT WEATHER AND DAILY SHOWERS/STORMS ARE
STILL ANTICIPATED THROUGH EARLY NEXT WEEK. SAME PATTERN REMAINS IN
PLACE WITH RIDGING SITUATED OVER THE FOUR CORNERS AND OFF THE EAST
COAST. A WEAKNESS BETWEEN BOTH (LOWER HEIGHTS & SUBSIDENCE) HAS
ALLOW FOR SCATTERED SHOWERS AND STORMS THESE LAST SEVERAL DAYS, AND
WILL CONTINUE TO DO SO TODAY AND IN MONDAY AS WELL (AND POSSIBLY A
BIT MORE WIDESPREAD). MOST OF THIS ACTIVITY SHOULD OCCUR DURING THE
DAYTIME ALONG THE SEA BREEZE. MUCH OF THIS ACTIVITY WILL LIKELY
OCCUR OVER THE SOUTHERN 2/3RDS OF OUR CWA WHERE CAM GUIDANCE HAS
SUGGESTED DEEP TROPICAL MOISTURE TO BE PRESENT (2-2.5 INCHES). STORMS
HAVE OVERALL BEEN VERY PULSY IN NATURE, SLOW MOVING AND VERTICALLY
STACKED WITH SUBOPTIMAL ORGANIZATION. STILL, THESE STORMS COULD
PRODUCE GUSTY WINDS, FREQUENTLY LIGHTENING AND STRONG DOWNPOURS AT
TIMES. AREAS THAT DON'T RECEIVE RAINFALL WILL STILL SEE FAIRLY HOT
WEATHER WITH HIGHS IN THE 90S AND HEAT INDICIES IN THE TRIPLE
DIGITS. PATCHY FOG MAY DEVELOP IN SPOTS DURING THE EARLY MORNING
HOURS AS WELL.
RAIN CHANCES TAPPER OFF INTO TUESDAY AS RIDGING BUILDS ACROSS THE
NORTHWESTERN GULF. 850MB TEMPERATURES SLIDE UPWARDS AGAIN AS
TEMPERATURES RISE AGAIN THROUGH THE END OF THE UPCOMING WORK WEEK.
