VFR CONDITIONS ARE EXPECTED THIS EVENING THEN DETERIORATE AGAIN OVERNIGHT AHD OF A COLD FRONT. AM EXPECTING FOG TO DVLP LOWERING VSBY'S TO AROUND 2SM FROM ALI TO VCT BUT COULD LOWER TO 1/4SM BRIEFLY. ADDITIONAL TSRA'S WILL BE POSSIBLE AHD AND ALONG THE FRONTAL BDRY WHICH IS EXPECTED TO MOVE THROUGH THE AREA FRI MORNING BTWN 10Z AND 13Z WITH WINDS SLIGHTLY INCREASING OUT OF THE N THROUGH MID MORNING. RESIDUAL RAIN WILL BE POSSIBLE IN THE WAKE OF THE FRONT. && .PREV DISCUSSION... /ISSUED 908 AM CDT THU SEP 29 2011/ DISCUSSION...A LINE OF STORMS MVG SW DOWN THE COAST IS EXPECTED TO REACH THE NRN MARINE ZONES/PORT OCONNOR AROUND 16Z. LARGE CAPE AND NO CIN IS IN PLACE OVER THE GULF WATERS ACCORDING TO THE LAPS. AS THE LINE PROGRESSES FARTHER DOWN THE COAST...MODELS SHOW DIVERGENCE DVLPG OVER THE COASTLINE AND NEARSHORE WATERS. THEREFORE AM EXPECTING THE PRECIP TO SHIFT MORE S AND SE WITH TIME. HAVE INCREASED POPS OVER THE MARINE ZONES TO CHC CATEGORY. SOME STORMS COULD PRODUCE GUSTS TO 35 KNOTS OR GREATER. OVER THE LAND...THE CAP IS STILL TOO STRONG AND SHOULD INHIBIT MOST OF THE CONVECTION FROM MAKING IT INLAND. UPDATES WILL BE OUT SHORTLY. PREV DISCUSSION... /ISSUED 638 AM CDT THU SEP 29 2011/ DISCUSSION...UPDATED FOR 12Z AVIATION DISCUSSION. AVIATION...FOG BECOMING AN ISSUE ONCE AGAIN THIS MORNING FOR VCT AND ALI TAF SITES. BOTH LOCATIONS HAVE BEEN DOWN TO 1/2 MILE FOR A TIME THIS MORNING...AND COULD DECREASE TO 1/4 MILE IN THE NEXT HOUR OR SO. EXPECT FOG TO LIFT SIMILAR TO YESTERDAY...BY AROUND 14UTC. CLOUDS EXPECTED TO DEVELOP THIS AFTERNOON...WITH ISOLATED THUNDERSTORMS POSSIBLE. BEST CHANCE FOR STORMS WILL BE AROUND THE VCT TAF SITE. HAVE INCLUDED CB IN AFTERNOON PERIODS AT THIS TIME...IF CONFIDENCE IMPROVES WILL NEED TO INCLUDE TEMPO GROUP LATER. WEAK COLD FRONT SAGS SOUTHWARD TOMORROW...STILL TOO FAR OUT FOR EXACT TIMING...BUT SHOULD BE APPROACHING VCT BY AROUND 12Z FRIDAY. PREV DISCUSSION... /ISSUED 413 AM CDT THU SEP 29 2011/ SHORT TERM (TODAY THROUGH FRIDAY)...ANOTHER HOT DAY EXPECTED TODAY WITH TEMPERATURES WELL ABOVE NORMAL FOR LATE SEPTEMBER. HAVE PLENTY OF CLOUD DEBRIS OVER THE AREA THIS MORNING FROM CONVECTION TO THE NORTH AND WEST LAST NIGHT. SHOULD LOSE MUCH OF THAT THIS MORNING BEFORE CU DEVELOP AHEAD OF THE SEA BREEZE THIS AFTERNOON. MAY BE ABLE TO GET SOME SHOWER/THUNDERSTORMS TO MOVE INTO NORTHWESTERN PORTIONS OF THE FORECAST AREA THIS EVENING FROM THUNDERSTORMS OVER THE SIERRA MADRE. RELATIVELY STRONG CORFIDI VECTORS THIS EVENING OUT OF THE WEST AND EVENTUALLY NORTHWEST. HAVE INCREASED POP FOR A BIT OF THE NORTHWEST AREA TO 30 THIS EVENING. COLD FRONT PROGGED TO MOVE INTO THE AREA TOMORROW. ALL MODELS ARE RATHER ROBUST WITH PRECIP DEVELOPING AHEAD OF THE FRONT FRIDAY. TAKING A CHANCE AND BUMPING POPS TO 30S FOR MUCH OF THE AREA DURING THE DAY ON FRIDAY AS MODELS HAVE BEEN INDICATING MOISTURE TO CONTINUE TO INCREASE ACROSS THE AREA...AND BECOME DEEPER THAN IT HAS BEEN. JUST TAKING A GLANCE AT 06Z NAM JUST COMING IN...SHEDDING A LITTLE MORE DOUBT ON PRECIP CHANCES AS IT VERY STRONGLY CUTS OF QPF JUST NORTH OF FORECAST AREA FRIDAY MORNING. IF ADDITIONAL MODEL RUNS LATCH ONTO THIS WOULD PROBABLY HAVE TO DROP POPS BACK TO 20 IN FUTURE FORECAST PACKAGES. LONG TERM (FRIDAY NIGHT THROUGH WEDNESDAY)...THE COLD FRONT WILL PUSH THROUGH THE REMAINDER OF THE CWA FRIDAY NIGHT...WITH DRIER AIR FILTERING INTO THE CWA OVER THE WEEKEND. BRUNT OF THE COLDER AIR WILL PASS WELL NORTHEAST OF THE REGION...BUT DRIER AIR COMBINED WITH EAST-NORTHEAST FLOW WILL PRODUCE TEMPS 5-10 DEG COOLER OVER THE CWA (ALTHOUGH NOT QUITE AS COLD AS WHAT THE GFS MOS IS SHOWING). BY THE MIDDLE TO LATTER PART OF NEXT WEEK ATTENTION WILL SHIFT WEST AS MODELS CONTINUE TO ADVERTISE DEEPENING WESTERN CONUS TROUGH...AS WELL AS LEAD SHORTWAVE APPROACHING TEXAS FROM BAJA. INITIALLY THIS WILL MEAN A GRADUAL WARMING AND MOISTENING TREND DAY 6-7 (TUE-WED) ACROSS SOUTH TEXAS AS WINDS TURN BACK SOUTHEAST. && .PRELIMINARY POINT TEMPS/POPS...
