SATELLITE ANALYSIS AND TRENDS...CONVECTIVE CLUSTER EXTENDING FROM NEAR
RND TO GYB CONTINUES TO DISPLAY GROWING ORGANIZATIONAL CHARACTERISTICS
IN RESPONSE TO STRONG MID TO UL JET STREAK ENERGY. LATEST WATER VAPOR
CAPTURES THE NOSE OF JET JUST ACROSS THE TX/OLD MEXICO BORDER NEAR
THE SRN EDGE OF CONVECTION AND EXTENDING WSW TO BAJA OF CALIFORNIA.
ATTM DRY AIR ALOFT IS SUPPORTING COLD POOL DEVELOPING AIDING IN FORWARD
PROPAGATING CELLS...HOWEVER STORMS ARE BEGINNING TO CONGEAL MORE AND
DEVELOPING MORE DOWNSTREAM ALONG SW TO NE ORIENTED SFC BOUNDARY...ALONG
AN AXIS FROM JUST SE OF SSF TO JAS. AS CLUSTER BECOMES MORE LINEAR
IN NATURE...WEDGE/V-SHAPED SIGNATURE IS BECOMING MORE NOTICEABLE IN IR
IMAGERY SUGGESTING INCREASING UL DIFFLUENCE AND LEADING TO A MORE REPEAT
CELL/TRAINING SITUATION.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 1045-1345Z...MEDIUM-HIGH CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...VERY INTENSE RAIN RATES IN EXCESS OF 2.0"/HR
HAVE ALREADY BEEN OBS PER RECENT REPORTS WITH CONVECTION. MODEST LLVL
MOISTURE CONVERGENCE AND SLIGHTLY HIGHER PWS (NEAR 1.8") FARTHER E ALONG
BOUNDARY ALONG WITH ADDITIONAL UPSTREAM ENERGY SHOULD HELP TO MAINTAIN A
PERIOD OF INTENSE RAINFALL OVER THE NEXT FEW HRS AS CONVECTIVE TRACKING
EWD TOWARD SE TX...INCLUDING HOUSTON METRO AREA.
