.PREV DISCUSSION... /ISSUED 946 PM CDT FRI JUL 3 2015/

DISCUSSION...
SCT CONVECTION HAS DISSIPATED W/ THE LOSS OF HEATING. SHOULD SEE
SEVERAL HOURS OF FAIRLY QUIET WX BEFORE ISO/SCT PRECIP BEGINS
DEVELOPING OFFSHORE AS SURGE OF DEEPER MOISTURE MAKES ITS WAY INTO
THE REGION FROM SWRN GULF.

EXPECT SCT CONVECTION TO DEVELOP AGAIN TOMORROW W/ HEATING &
SEABREEZE. WILL LIKELY SEE MORE AREAL COVERAGE THAN WE SAW TODAY.
FCST SOUNDINGS HINTING AT AN INVERTED-V PROFILE SO WILL NEED TO
KEEP AN EYE ON THE POTENTIAL FOR SOME HIGHER WIND GUSTS IN THE
STRONGER CELLS. GOOD IDEA TO STRESS LIGHTNING SAFETY AS WELL
CONSIDERING ALL THE OUTDOOR ACTIVITIES GOING ON AS WELL...

GUIDANCE SUGGESTS THAT DESPITE INCREASED COVERAGE DURING THE
DAY...VAST MAJORITY OF PRECIP SHOULD DISSIPATE BEFORE FIREWORKS
SHOWS BEGIN.  47

PREV DISCUSSION... /ISSUED 739 PM CDT FRI JUL 3 2015/
AVIATION...
MOSTLY VFR CONDITIONS ON TAP FOR THE NEXT 24 HOURS. BIGGEST
IMPACT TO AVIATION WILL LIKELY BE SCATTERED SHOWERS AND
THUNDERSTORMS ASSOCIATED WITH SEABREEZE. A LINE OF SHOWERS AND
THUNDERSTORMS WILL BEGIN MOVING INLAND FROM THE COAST BY MID
MORNING AND SHOULD PASS THROUGH THE HOUSTON METRO TERMINALS
BETWEEN 18 AND 22Z. PREVAILING WINDS WILL BE FROM THE SOUTH AT 5
TO 10 KNOTS...HOWEVER WINDS UP TO 25 KTS ARE POSSIBLE IN THE
VICINITY OF THUNDERSTORMS. 44
