SATELLITE ANALYSIS AND TRENDS...LATEST VISIBLE SATELLITE IMAGERY
INDICATES THAT HUMBERTO CONTINUES TO LIFT SLOWLY TO THE NORTH WITH A
CENTER ESTIMATED TO BE IN THE VIC OF 28.5N/94.9N.  OVER THE LAST COUPLE
OF HOURS CONVECTION HAS RAPIDLY COOLED ALONG AND JUST OFFSHORE BRAZORIA
COUNTY AND GALVESTON ISLAND.  THE MOST INTENSE CONVECTION APPEARS TO BE
NEAR THE WESTERN TIP OF GALVESTON ISLAND VERY NEAR THE WEST BAY AREA.
MANUAL AND AUTOMATED SATELLITE ESTIMATED RAINFALL RATES WITH THIS
CONVECTION WAS RUNNING AROUND 2.0"/HR AND BELIEVE THAT RAINFALL RATES OF
UP TO THIS MAGNITUDE ARE QUITE POSSIBLE MOSTLY FROM NE BRAZORIA COUNTY
TO GALVESTON ISLAND OVER THE NEXT FEW HOURS.
.
OVER SW LA OUTFLOW BANDS WITH EMBEDDED HEAVY CONVECTION CONTINUES TO
MOVE IN OVER PORTIONS OF SW LA WITH MOST RAPIDLY COOLING CLOUD TOPS AND
ASSOCIATED HEAVY RAINFALL CURRENTLY LOCATED FROM THE VIC OF MARSH ISLAND
AND INTO SE VERMILLION PARISH.  AUTOMATED AND MANUAL SATELLITE ESTIMATED
RAINFALL RATES WITH THIS CONVECTION ALSO RUNNING IN THE 1.5-2.0"/HR RANGE.
.
SHORTWAVE TROF ON WV IMAGERY OVER THE CNTRL ROCKIES CONTINUES DIGGING
SE AND THIS WILL HELP TO EVENTUALLY IMPART A NEWARD MOTION TO SYSTEM.
WV IMAGERY AND GOES DERIVED WINDS BEGINNING TO SHOW OUTFLOW JET DEVELOPING
FROM E CNTRL TX INTO NW LA.  THIS MAY HELP TO FOCUS CONVECTION ALONG
REMNANT SYNOPTIC BOUNDARY OVER SE TX AND W CNTRL LA IN ADVANCE OF THE
CENTER OF HUMBERTO.  WILL CONTINUE TO MONITOR.
