EVENT...TRAINING EVENT LOOKS LIKELY FOR AT LEAST THE NEXT HOUR FROM
NORTHERN FORT BEND COUNTY INTO SOUTHERN HARRIS COUNTY
.
SATELLITE ANALYSIS AND TRENDS...EARLIER CONVECTION OVER CNTRL AND NORTHERN
HARRIS COUNTY HAS BOWED EAST WITH BOOKEND VORTICE LIFTING INTO EASTERN
MONTGOMERY COUNTY PER LATEST COMPOSITE RADAR IMAGERY.  SURFACE DATA
REVEALS THAT A COLD POOL HAS BECOME ESTABLISHED OVER HARRIS COUNTY WITH
AN ASSOCIATED OUTFLOW BOUNDARY JUST SOUTH OF AN AXIS FROM SGR TO HOU.
THIS BOUNDARY HAS BEEN THE FOCUS FOR TRAINING CONVECTION FOR THE LAST HOUR
OR SO AND BELIEVE THAT THIS THREAT SHOULD CONTINUE FOR THE NEXT HOUR.
ALREADY SEEING RAPID CLOUD TOP COOLING WITH CONVECTIVE CELLS OVER N
FORT BEND AND THEY SHOULD PROGRESS EWARD OVER AREAS THAT HAVE ALREADY
RECEIVED HEAVY RAIN.  GOES SOUNDER DPI PRODUCTS SHOWING THAT INSTABILITY
AXIS APPEARS TO BE ALIGNED JUST ALONG AND WEST OF ONGOING CONVECTION
AND THAT COUPLED WITH OBJECTIVELY DERIVED SURFACE MOISTURE CONVERGENCE
JUST UPSTREAM OF ONGOING CONVECTION RAISES THE THREAT FOR REGENERATING
CONVECTION.  CLOUD DEPTHS NOT AS IMPRESSIVE AS EARLIER CONVECTION OVER
HARRIS COUNTY BUT STILL 1.30-1.50" PRECIPITABLE WATERS SHOULD ALLOW FOR
RAINFALL RATES OF 1-2"/HR IN THE MOST INTENSE CORES.  HEAVIEST RAINFALL
THREAT LOOKS TO BE ABOUT 10 MILES SOUTH OF I-10 FROM NEAR FULSHEAR IN
NORTHERN FORT BEND TOWARDS HOU.  WILL CONTINUE TO MONITOR.
