Severe Thunderstorm Warning 140, NWS Houston/Galveston, TX

SOUTHEAST TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
255 PM CDT FRI JUL 11 2003

STILL EXPECTING CONVECTION TO FIRE ALONG THE SEABREEZE AND LEFTOVER
OUTFLOW BOUNDARY THIS AFTN. HOWEVER THE ADDITIONAL REMNANT/OVERNITE
STORMS MOVING ACROSS THE NRN ZONES ARE THE ONES WE ARE TAKING A BIT
MORE NOTICE OF. THIS SMALL COMPLEX APPEARS TO BE MOVING INTO A VERY
UNSTABLE AMS AND AS A RESULT...THIS PORTION OF THE CWA HAS BEEN PUT
IN A SVR WATCH FOR THE REMAINDER OF THE AFTN.

THE REST OF THE FORECAST PCKG NOT AS CLEAR CUT AS THE MODELS WOULD
LIKE TO PORTRAY EITHER. PROGGED TRENDS WOULD SEEM TO INDICATE SOME
DRYING IS IN ORDER FOR THE CWA THE NEXT COUPLE OF DAYS AS PWS DROP
TO AOA 1.5 (SAVE FOR THE ERN CWA/COAST). THE BUILDING UPPER RIDGE
LOOKS TO BE THE PRIMARY CULPRIT. HOWEVER...HAVING SAID ALL OF THIS
AM INCLINED TO STILL KEEP POPS ABOVE GUIDANCE THE NEXT DAY OR SO.
THIS TREND OF LOWER PWS HAS BEEN ADVERTISED BY THE MODELS THE LAST
SEVERAL RUNS BUT HAS YET TO REALLY MATERIALIZE. SO WILL LIKELY ERR
ON THE SIDE OF WET FOR THE TIME BEING. PERSISTENT UPPER LEVEL DIV-
ERGENCE AND SPORADIC WEAK S/W ACTIVITY FROM THE INCREASINGLY NNWLY
FLOW ALOFT ALSO MAKING A GOOD CASE FOR BETTER THAN SLIGHT CHC POPS
TOMORROW AND SUN. AS FOR T.S. CLAUDETTE...THE OFFICIAL TRACK STILL
PUSHES THE SYSTEM INTO FAR S TX EARLY NEXT WEEK. SO...UNLESS SOME-
THING REALLY DRAMATIC COMES FROM THE NEXT HOTLINE CALL...WILL PRO-
BABLY KEEP WITH WHAT WE ALREADY HAVE IN THE EXTENDED. 41/37/45

.HGX...NONE.
