FOG DEVELOPING OVER SW ZONES EARLY THIS MORNING WITH A COUPLE OF
SPOTS ALREADY DOWN BELOW A MILE IN VISIBILITY. THE FOG SHOULD
BURN OFF QUICKLY BY 9 AM. SCATTERED SHRA HAVE BEEN AFFECTING THE
EASTERN MARINE WATERS TONIGHT...SLOWLY WORKING ITS WAY TOWARDS
THE COAST. DO NOT EXPECT THIS ACTIVITY TO MAKE IT VERY FAR
INLAND AS THE AIRMASS IS MUCH DRIER (PWS 1.0-1.2 INCHES). WILL
WATCH CONVECTIVE TRENDS AND MAY BUMP COASTAL POPS UP FIRST PERIOD
IF NECESSARY. TEMPS THIS MORNING ARE STARTING OUT ABOUT 5 DEGREES
WARMER THAN YESTERDAY MORNING...AND WITH PLENTY OF SUNSHINE MAX
TEMPS SHOULD END UP ABOUT 5 DEGREES WARMER THAN YESTERDAY.
QUIET WEATHER STILL ANTICIPATED FOR THE UPCOMING 7 DAYS. WEAK
UPPER RIDGING WILL BUILD OVER SE TX BY MONDAY WHICH WILL PERSIST
THROUGH THE END OF NEXT WEEK. PERSISTENT EAST/NORTHEAST SFC FLOW
WILL KEEP DEEP TROPICAL MOISTURE CUTOFF FROM THE AREA. PATCHY FOG
WILL DEVELOP IN THE LATE NIGHT/EARLY MORNINGS IN RURAL AREAS. A
WEAK SEABREEZE WILL DEVELOP EACH DAY SUNDAY THROUGH TUESDAY WHICH
COULD LEAD TO THE DEVELOPMENT OF A FEW AFTERNOON SHOWERS TOWARDS
THE COAST. HAVE ONLY MENTIONED PRECIP MONDAY/TUESDAY WHEN THE BEST
MOISTURE IS PRESENT (PWS 1.4-1.6 INCHES). DRIER AIRMASS AGAIN
SPREADS INTO SE TX FROM THE EAST BEGINNING WEDNESDAY WITH PWS
DROPPING BACK DOWN TO AROUND AN INCH...ONCE AGAIN LIMITING CONVECTIVE
DEVELOPMENT. TEMPS EACH DAY WILL WARM TO THE UPPER 80S/LOWER 90S
INLAND...MID 80S ALONG THE COAST. AFTERNOON HEAT INDICES WILL TOP
OUT IN THE 91 TO 94 DEGREE RANGE WHICH WILL BE SOMEWHAT OF AN
IMPACT WHERE POWER OUTAGES REMAIN. OVERNIGHT LOWS COULD COOL DOWN
A FEW DEGREES LATE WEEK WHEN THE DRIER AIRMASS MOVES IN...BUT
THIS IS NOT REFLECTED IN THE CURRENT FORECAST.
