EVENT...HEAVY CONVECTION IN AND NEAR THE HOUSTON METRO AREA
.
SATELLITE ANALYSIS AND TRENDS...OVER THE THE LAST 1-2 HOURS CONVECTION
HAS FORMED ALONG REMNANT MESOSCALE AND GULF BREEZE BOUNDARIES AND HAS
RAPIDLY INCREASED IN COVERAGE AND INTENSITY OVER THE HOUSTON METRO AREA.
OVER THE LAST 20-30 MINUTES CONVECTION HAS CONSOLIDATED FROM E FORT BEND
COUNTY EXTENDING TOWARDS HOU AND FROM THERE TOWARDS N GALVESTON BAY.
THE EXTREMELY RAPID COOLING OF THE STORM COMPLEX ALONG WITH ASSOCIATED
OVERSHOOTING TOPS IN COMBINATION WITH SEASONABLY HIGH MOISTURE (1.80-1.90"
GOES DERIVED PWS) AND RELATIVELY WEAK CLOUD LAYER SHEAR SUGGEST THAT
RAINFALL RATES ARE LIKELY RUNNING AT LEAST 2.0" OVER THE SOUTHERN
HOUSTON SUBURBS.  OUTFLOW AND GULF BREEZE COLLISIONS SHOULD ALSO ALLOW
FOR ADDITIONAL CONVECTIVE DEVELOPMENT OVER CNTRL/WSTRN FORT BEND AND
E WHARTON COUNTIES AND IT APPEARS THIS IS ALREADY IN PROGRESS WITH THE
RAPIDLY DEVELOPING CB NEAR PLEAK.  ADDITIONAL BOUNDARY INTERACTIONS LOOK
LIKELY OVER GALVESTON COUNTY OVER THE NEXT 30 MINUTES WHICH WILL ALSO
SPREAD HEAVY RAIN INTO THIS AREA.  WILL CONTINUE TO MONITOR.
