AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 332 PM CDT TUE AUG 25 2009 .DISCUSSION... SCT SHRA/TSTMS POPPING UP AREAWIDE WITH THE HEAT OF THE DAY COMBINED WITH SOME UPPER LEVEL ENERGY MOVING INTO THE AREA FROM THE EAST. MAY SEE SOME PULSE SEVERE STORMS ACROSS THE AREA...ESP W OF I-45...WITH INVERTED-V SOUNDING PROFILE SUGGESTING THE POTENTIAL FOR DOWNBURSTS. STILL HAVE DECENT AVAILABLE MOISTURE IN PLACE AGAIN TOMORROW. MODELS SUGGESTING NOSE OR LFQ OF JET MOVING INTO THE AREA FROM THE NW PERIPHERY OF THE UPPER LOW MOVING INTO LA WHICH MAY ENHANCE AREAL COVERAGE. BUMPED POPS UP ABOVE GUIDANCE. SHORTWAVE DIGS DOWN THE PLAINS THUR/FRI AND DRAGS A FRONTAL BOUNDARY INTO NORTHERN PORTIONS OF THE AREA EARLY FRI - THEN STALLS IT OUT SOMEWHERE NORTH OF I-10 THRU THE WEEKEND. FLOW EVENTUALLY BECOMES SWLY ALOFT THIS WEEKEND BRINGING A SERIES OF UPPER DISTURBANCES/JET STREAKS OVERHEAD. THIS...ALONG WITH HEATING SHOULD COMBINE WITH THE MOISTURE POOLED AHEAD OF THE BOUNDARY TO PROVIDE CHANCES OF SHRA/TSTMS THRU THE PERIOD. GFS SHOWING A DEEP SLUG OF TROPICAL MOISTURE MOVING IN EARLY NEXT WEEK CONTINUING THE PATTERN OF SOME MUCH WELCOME RAINFALL. 47 && .MARINE... A WEAK PRESSURE GRADIENT WILL KEEP WINDS LIGHT FOR THE REMAINDER OF THE WEEK. SEAS WILL GENERALLY RUN 2 FOOT OR LESS. AN UPPER LOW MOVING SOUTH-SOUTHWESTWARD FROM MS TO LA WILL KEEP A WEDGE OF DEEPER MOISTURE OVER THE COASTAL WATERS TONIGHT THROUGH FRIDAY. THIS WILL ALLOW SCATTERED THUNDERSTORMS TO OCCUR AND SOME OF THE STORMS WILL PRODUCE GUSTY WINDS. 40 && .105 PM AVIATION... VFR CONDITIONS ARE EXPECTED THROUGH THE PERIOD. THE MAIN ITEM OF INTEREST CONCERNS THUNDERSTORM CHANCES THIS AFTERNOON...A SLIGHT CHANCE FOR THUNDERSTORMS WEDNESDAY MORNING...AND A REMOTE CHANCE FOR ISOLATED LIGHT FOG EARLY WEDNESDAY MORNING. THUNDERSTORM ACTION LOOKS TO BE ISOLATED TO SCATTERED ACROSS THE AREA THIS AFTERNOON. THIS WILL BE MAINLY DUE TO THE SEABREEZE MOVING INLAND AND INTERACTING WITH SHORTWAVE TROUGHS ALOFT MOVING SOUTHWARD AROUND THE UPPER LOW OVER MS. OTHER STORMS WILL BE POSSIBLE DUE TO OUTFLOW BOUNDARY INTERACTIONS LATER THIS AFTERNOON. FELT CONFIDENT ENOUGH TO PLACE A TEMPO SECTION FOR THE BIG METRO AIRPORTS AND SOUTHERN METRO HOUSTON TERMINALS. THE MODELS PARTICULARLY SHOW THE POTENTIAL FOR GUSTY WINDS AT BOTH KUTS AND KCLL BETWEEN 23Z AND 02Z THIS EVENING...ALTHOUGH IT LOOKS LESS LIKELY FOR KUTS. WITH THE UPPER LOW DRIFTING SOUTH-SOUTHWESTWARD THROUGH LA... ANOTHER ROUND OF MORNING THUNDERSTORMS LOOK TO BE POSSIBLE ON WEDNESDAY. THE 12Z LOCAL 4KM WRF MODEL SHOWED THIS POSSIBILITY. REFLECTED THIS IDEA WITH A CB GROUP FOR ALL BUT THE KCLL TERMINAL. GUIDANCE SUGGESTS THAT KCXO MAY EXPERIENCE MVFR CONDITIONS DUE TO LIGHT FOG AROUND AND SHORTLY AFTER SUNRISE WEDNESDAY MORNING. FELT THAT THIS WOULD BE MORE LIKELY IF THE SITE RECEIVES RAIN THIS AFTERNOON. OTHERWISE...FOG IS PROBABLY NOT LIKELY. THUS THE COMPROMISE 6SM. 40 && .PRELIMINARY POINT TEMPS/POPS...
