AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
946 AM CDT WED JUL 11 2012

.DISCUSSION...
ATTM LOOKS LIKE RAINFALL RATES HAVE DIMINISHED TO MORE MANAGEABLE
LEVELS FOR MOST LOCATIONS - GENERALLY 1/2" PER HOUR OR LESS. A FEW
EXCEPTIONS BEING OUT TOWARD THE MCV NW OF HOUSTON AND ALSO IN THE
CONVECTIVE ACTIVITY SW. SO LONG AS RATES REMAIN ON THE LOWER END
MOST LOCATIONS SHOULD BE ALRIGHT. HOWEVER...THE GROUND IS
SATURATED AND ANYTHING MUCH ABOVE 1"/HR WILL POSE PROBLEMS AS
IT'LL RUNOFF QUICKLY. WILL CONTINUE THE FF WATCH.

SAT PIX SHOW SOME BREAKS IN THE CLOUDINESS ACROSS JUST N & W OF
THE CWA. LOOKING FOR STORMS TO DEVELOP THERE THIS AFTN WITH
DAYTIME HEATING. CONVECTIVE NATURE OF THESE STORMS WILL PROBABLY
PRODUCE THE HIGHER RAINFALL RATES...SO YOU NRN FOLKS AREN'T OUT OF
THE WOODS JUST YET.

QUICK LOOK AHEAD...LOOKS WET AGAIN THURS. MORE LATER.  47
