AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 858 AM CDT TUE APR 14 2015 .DISCUSSION... DID A QUICK UPDATE TO RAISE POPS AT/ALONG THE COAST DUE TO CURRENT LINE OF STORMS. NOT SURE HOW FAR INLAND THIS ACTIVITY WILL GO (A MAJORITY OF IT COULD REMAIN OFFSHORE)...SO KEPT POPS IN A 50%-60% RANGE FOR THOSE AREAS. LOCALLY HEAVY RAINFALL (POTENTIAL FOR 3 TO 4 INCHES IN A SHORT PERIOD OF TIME) COULD LEAD TO SOME FLOODING NEAR THE COAST. ALSO COULD SEE SOME MARINE WIND GUSTS >34 KNOTS. 42 && .PREV DISCUSSION... /ISSUED 458 AM CDT TUE APR 14 2015/ DISCUSSION... ACTIVITY OUT TO THE W/SW WILL BE MOVING INTO THE AREA LATER THIS MORNING/AFTN AS A DISTURBANCE INTERACTS WITH THE STALLED FRONTAL BOUNDARY OVER THE NRN HALF OF THE CWA. AS SUCH THE SOMEWHAT UNEX- PECTED YET SOMEWHAT WELCOME RESPITE YESTERDAY FROM THE RAIN WILL BE ENDING TODAY. MAIN THREAT WITH THESE STORMS LIKELY HEAVY RAIN AND LOCALIZED FLOODING GIVEN THE SLOW STORM MOVEMENT/PRESENCE OF A LOW-LEVEL BOUNDARY (BE IT THE STALLED COLD FRONT OR SEABREEZE). THE COLD FRONT IS PROGGED TO SLOWLY SAG A BIT FURTHER SOUTH THIS AFTN...BUT STILL NOT REACHING THE COAST BEFORE IT FINALLY STOPS/ WEAKENS TONIGHT. ONSHORE WINDS SET TO RESUME AREAWIDE TOMORROW. THE MAIN ISSUE WITH THE REST OF THE FCST REMAINS TIMING OF THESE ASSORTED DISTURBANCES AS THEY EJECT AROUND THE BOTTOM OF THE LIN- GERING (TO VERY SLOW EWD MOVING) UPPER LOW/TROF AXIS OVER FAR NW TX. WILL KEEP CHC POPS IN THRU THE REST OF THE WEEK...BUT EXPECT- ING THEM TO PEAK THURS AS THE MAIN UPPER SYSTEM APPROACHES ALONG WITH ANOTHER FRONT. EXTENDED MODELS IN SLIGHTLY BETTER AGREEMENT WITH THE PATTERN CHANGE NEXT WEEK OF WEAK UPPER RIDGING AND MUCH DRIER WX. 41 MARINE... LIGHT WINDS THIS MORNING SHOULD GRADUALLY INCREASE THIS MORNING BECOMING MORE SOUTHERLY. SEABREEZE SHOULD FORM AND BECOME A FOCUS FOR SHOWERS AND THUNDERSTORMS IN THE AREA OF THE BAYS AND SHOWERS OVER THE GULF WATERS. WEAK COLD FRONT SAGS SOUTH TODAY AND MAY INTERACT WITH SEABREEZE BEFORE MOVING OFF THE COAST WEDNESDAY MORNING BUT WINDS REMAIN LIGHT. SE FLOW REDEVELOPS BY LATE WEDNESDAY AND INCREASES AS UPPER TROUGH SETS UP OVER THE 4 CORNERS...SEAS SHOULD RESPOND BUILDING TO 4 TO 6 FEET THURSDAY NIGHT. EVENTUALLY COLD FRONT CREEPS OFF THE COAST AGAIN SATURDAY MORNING. 45 AVIATION... LOW CIGS AND FOG DEVELOPING ALONG AND NORTH OF THE FRONTAL BOUNDARY IN THE VICINITY OF CLL/UTS. THE FRONTAL BOUNDARY SHOULD SAG SOUTH AND MAY IMPACT CXO AREA BEFORE SUNRISE. THE HOUSTON HUBS SHOULD ESCAPE THE WORST OF IT DUE TO THE LATER ARRIVAL OF THE BOUNDARY AND DAYTIME HEATING...SOME MVFR CIGS POSSIBLE 12-17Z BEFORE SHOWERS AND THUNDERSTORMS BECOME MORE COMMON ALONG THE COAST. MAY HAVE SIGNIFICANT IMPACTS FOR LBX TERMINAL THIS AFTERNOON AND COULD IMPACT SGR/HOU THIS AFTERNOON AS WELL DEPENDING ON HOW FAR INLAND THE SEABREEZE PUSHES AND THE PLACEMENT OF FRONTAL BOUNDARY. 45 && .PRELIMINARY POINT TEMPS/POPS...
