NWS Houston/Galveston, TX wrote its last area forecast discussion before the first event at Aug 27, 9:09 AM CST, 3 hours 27 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 1009 AM CDT MON AUG 27 2007 .DISCUSSION... TSRA DEVELOPING ALONG THE REMAINS OF THE EARLY MORNING CONVECTION OUTFLOW. ATMOSPHERE MODERATELY UNSTABLE AND CONVECTIVE TEMPERATURES OF 89-91 LOOK EASILY ATTAINABLE BY 2 PM. UPPER LOW SPINNING AWAY OVER CLL AREA SHOULD CONTINUE TO DRIFT WEST THIS AFTERNOON PLACING MOST OF SETX UNDER GREATER DIFFLUENCE ALOFT. HAVE NUDGED UP POPS OVER THE AREAS ALONG THE BOUNDARY ANAHUAC-HOU- CLL AND HAVE MADE SOME CHANGES TO ANTICIPATED CLOUD COVER (INCREASED FOR AREAS MAINLY EAST AND SOUTHEAST OF THE UPPER LOW). ZFP AND ASSOCIATED PRODUCTS ARE ALREADY OUT. NOTE...KHGX RADAR IS UP AND RUNNING BUT IS BEING CLOSELY MONITORED. ADDITIONAL PARTS MAY BE INSTALLED THIS AFTERNOON BUT SHOULD ONLY TAKE ABOUT 30 MINUTES TO DO SO. PLEASE CHECK THE FTM FOR LATEST ON THE RADAR. 45 && .PREV DISCUSSION... /ISSUED 612 AM CDT MON AUG 27 2007/ AVIATION... VFR CONDITIONS EXPECTED. THE EXCEPTIONS WILL BE MVFR CONDITIONS IN AND AROUND ISOLATED TO SCATTERED THUNDERSTORMS...ALTHOUGH FELT THAT THIS POSSIBILITY WAS A BIT TOO LOW TO PINPOINT. A WEAK OUTFLOW BOUNDARY WAS CURRENTLY NEAR A LINE FROM CLL TO NEAR GALVESTON BAY. THIS BOUNDARY AND THE SEABREEZE WILL HELP GENERATE THE CONVECTION BY THE EARLY AFTERNOON. THE GFS AND NAM BUFR SOUNDING MODELS FORECAST A CONVECTIVE TEMPERATURE OF THE MID 80S AT CLL AND THE LOWER 90S AT IAH AND TIME SECTIONS OF THE MODEL DATA SUGGESTS THE MOST LIKELY TIME PERIOD FOR STORMS TO BE FROM 19Z TO AROUND SUNSET. THE BEST LOCATION MAY PROBABLY BE LBX IF THE OUTFLOW BOUNDARY CAN WORK ITS WAY SOUTHWESTWARD AND INTERACT WITH THE SEABREEZE. 40 PREV DISCUSSION... /ISSUED 330 AM CDT MON AUG 27 2007/ DISCUSSION... MOISTURE LEVELS SHOULD REMAIN ON THE HIGH SIDE THROUGH FRIDAY. GFS AND TO A LESSER EXTENT THE NAM BOTH BRING A S/WV THROUGH THE AREA TODAY. THIS S/WV COUPLED WITH DAYTIME HEATING SHOULD TRIGGER SCATTERED SHOWERS AND THUNDERSTORMS TODAY. THE WEAK 850 MB HIGH PRESSURE SYSTEM OVER SOUTHEAST TEXAS YESTERDAY WHICH LIMITED CONVECTIVE COVERAGE IS NOW OVER THE ARKLATEX AND A VERY WEAK UPPER LOW IS OVER EAST CENTRAL TEXAS. STORMS THAT MOVED WEST INTO THE SE TX AROUND 06Z SHOULD LEAVE A BOUNDARY ACROSS SE TX. FIRST GUESS IS THAT THE BOUNDARY WILL LIE ALONG A CLL TO GLS LINE. SINCE THE DEEPER MOISTURE IS SW OF THIS BOUNDARY...FEEL BEST RAIN CHANCES SHOULD BE OVER THE SOUTHWEST ZONES TODAY. A SUBTLE WEAKNESS ALOFT AND VARYING SURGES OF HIGH PW AIR SHOULD ALLOW SCATTERED TSRA TO DEVELOP EACH DAY THIS WEEK. THE LACK OF A LARGE SCALE FEATURE OR SYNOPTIC BOUNDARY PRECLUDE HIGHER POPS BUT THERE WILL BE A DAY OR TWO THIS WEEK THAT COULD END UP A WASH-OUT. GFS MOVES THE PRECIP WEST AND NORTH OVER LABOR DAY WEEKEND. THE ECMWF KEEPS MOISTURE IN PLACE. NOGAPS AND THE CANADIAN MODELS BOTH SUPPORT THE MORE MOIST ECMWF. WILL KEEP CHANCE POPS GOING THROUGH LABOR DAY. MARINE WINDS SHOULD REMAIN LIGHT AND SEAS FLAT FOR THE NEXT FEW DAYS. 43 && .PRELIMINARY POINT TEMPS/POPS...
