.UPDATE...
SOUTHEAST TEXAS REMAINS ON SUBSIDENT SIDE OF LARGE MCV LOCATED
OFFSHORE SOUTH OF GALVESTON. WITH DRIER AIR IN PLACE ACROSS THE
REGION CONVECTIVE COVERAGE SHOULD BE MUCH LESS THAN YESTERDAY
ALTHOUGH A FEW ISOLATED THUNDERSTORMS COULD BE POSSIBLE ACROSS OUR
NORTHEASTERN COUNTIES LATER TODAY WHERE THE CAP IS SLIGHTLY
WEAKER. CURRENT FORECAST IS IN GOOD SHAPE WITH ONLY MINOR CHANGES
TO THE WIND GRIDS FOR THE UPDATE. 38

&&

.MARINE...
SOUTH TO SOUTHEAST WINDS 10-15 KTS WILL BE THE NORM THE NEXT FEW
DAYS. THOUGH A DIP TO AROUND 10 KN TS POSSIBLE WITH THE S/W UPPER
RIDGING ROLLING ACROSS SETX AND INTO THE NORTHWEST GULF THEN
DEEPENING TROUGHINESS OVER THE ROCKIES WILL PRIME THE SOUTHERLY FLOW
AND THEN STRENGTHEN IT AS THE UPPER LOW MOVES INTO EXT N TX MONDAY
NIGHT.

.AVIATION...
MVFR CIGS/VISBY SLOWLY IMPROVING AND EXPECT THEM TO LIFT QUICKLY
AS TEMPERATURES CLIMB INTO THE 79-82 DEGREE RANGE. CAP SHOULD BE
ENOUGH TO LIMIT DEVELOPMENT TODAY. HAVE REMOVED VCSH FROM LBX BUT
HAVE ADDED VCSH FOR UTS FROM 19-23Z WHERE CAP SHOULD BE THE WEAKEST
AND MAY HAVE SOME LIFT AS S/W TRAVERSES THE AREA. MVFR CIGS LOOKING
MORE LIKELY WITH THE NEW 12Z NAM. WILL EVALUATE THE WRF/GFS FOR THE
18Z PACKAGE.
