SOUTHEAST TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 910 PM CDT SUN JUL 7 2002 SHORTWAVE TRACKING WESTWARD ACROSS LOUISIANA THIS EVENING WITH SEVERAL CLUSTERS OF STRONG TO SEVERE TSRA OCCURRING. 18Z MESOETA SHOWS THIS SHORTWAVE AND ASSOCIATED UVV SPREADING ACROSS EASTERN ZONES NEXT FEW HOURS. 00Z LCH SOUNDING SHOWS PW OF 1.91 INCHES...VERY STEEP 850-700 MB LAPSE RATE...AND CAPE OF 6000. SURFACE DEWPOINTS POOLING IN THE UPPER 70S ACROSS CWA AHEAD OF CONVECTION. GIVEN EXTREME INSTABILITY IN PLACE AND AXIS OF MOISTURE CONVERGENCE...BELIEVE CONVECTION WILL PERSIST AT LEAST A FEW MORE HOURS AS IT SPREADS INTO CWA DESPITE LOSS OF DAYTIME HEATING. WILL GO 40 POPS/POSSIBLE SEVERE EASTERN ZONES OVERNIGHT AND 20 POPS ELSEWHERE. NO OTHER CHANGES TO FCST. 35/43 .HGX...NONE. PRELIMS... CLL BB 074/095 075/094 075 242 IAH BB 076/095 076/094 076 442 GLS BB 079/091 080/090 080 442 PREVIOUS DISCUSSION... ISOLATED TSRA STARTING TO POP UP OVER THE CWA THIS AFTERNOON JUST AS THE S/W MOVES IN AND WE APPROACH PEAK HEATING. MODELS NOT INDICATING ANYTHING TOO DIFFERENT THAN WHAT THE CURRENT FORECAST IS ADVERTISING ATTM...SO NO MAJOR CHANGES ARE LIKELY WITH THIS PACKAGE. THE PERSIS- TENT (AND DEEP) E/SE FLOW SHOULD KEEP BRINGING WEAK S/WS TO THE CWFA AS THE UNSTABLE AIRMASS CONTINUES TO MOISTEN UP (PEAKING AOA 2.2 BY TUES). BY MID WEEK...THE STRONG UPPER RIDGE OVER THE WRN STATES WILL BE IN PLACE JUST AS A COOL FRONT APPROACHES FROM THE NORTH. ITS NOT LIKELY THE FRONT WILL MAKE IT TO THE COAST BUT THE PRE-FRONTAL ENVI- RONMENT IS PROGGED TO BE ON THE HOT/DRY/CAPPED SIDE. SFC AND MID LVL WINDS FROM THE SW SHOULD PUT A KIBOSH ON ANY WIDESPREAD PCPN FOR THE LATTER HALF OF THE WEEK. HOWEVER THE LONG-RANGE GUIDANCE NUMBERS ARE STILL NOT REFLECTING THIS THINKING. AS FOR THE AREA OF DISTURBED WX IN THE GULF...ALL/MOST OF THE MODELS ARE POINTING TO BROWNSVILLE AND POINTS SOUTHWARD AS BEING THE LIKELY WINNERS OF THE TROPICAL RAIN POOL. 41/45
