AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 230 PM CDT SAT JUL 17 2004 .DISCUSSION... DIFFICULT FCST ON TAP REGARDING POPS FOR THE NEXT 24 HOURS. FRONTAL BOUNDARY IN N TX HAS MADE SOME VERY SLOW SWD PROGRESS DURING THE PAST SEVERAL HOURS AND IS NOW SITUATED ALONG A LINE FROM ROUGHLY SJT-TXK. MODELS IN FAIR AGREEMENT BRINGING THIS BOUNDARY TO EXTREME NRN PARTS OF THE CWA BY MIDNIGHT. HOW FAR SOUTH IT MAKES IT IS STILL UP IN THE AIR. BEST GUESS AT THIS POINT IS THAT IT WILL STALL SOMEWHERE BETWEEN THE I-10 CORRIDOR AND THE COAST SUNDAY AFTN. IN THE MEANTIME...GRAPHICAL MODELS CONTINUE TO ADVERTISE SOME CONVECTIVE DEVELOPMENT ALONG THE BOUNDARY THIS EVENING AND DRIFTS IT SOUTH OVERNIGHT - THOUGH NUMERICAL GUIDANCE DOES NOT SEEM TO REFLECT THIS FOR SOME REASON. BOTH GFS/ETA DEPICT A S/W EMBEDDED IN THE NORTHERLY FLOW HEADING OUR WAY TONIGHT. CANT PICK OUT ANYTHING REAL SIGNIFICANT ON WATER VAPOR PIX RIGHT NOW...BUT THERE MAY BE ONE OR TWO IMPULSES MIXED IN WITH THE CLUTTER BETWEEN COLORADO AND OK. GFS IS STILL THE MORE AGGRESSIVE MODEAL COMPARED TO ETA WITH AREAL COVERAGE AND OMEGA FIELDS. CURRENT GPS SOUNDER PLOT SHOWS PWS >2 POOLING ALONG THE BOUNDARY EAST OF INTERSTATE 45 AND INTO LOUISIANA. STILL A RESPECTABLE 1.6-1.8 WEST OF I-45. UNTIL I SEE SOME DEVELOPMENT UPSTREAM...AM HESITANT TO MESS WITH THE ONGOING POPS. WILL MAINTAIN THE HIGHER POPS ACROSS THE NE ZONES AND ALSO MAINTAIN THE SEVERE WORDING ALREADY IN PLACE UP THERE. DYNAMICS ON THE MARGINAL SIDE AND DONT ANTICIPATE WIDESPREAD SEVERE WX...BUT CANT RULE OUT PULSE SEVERE ESPECIALLY THIS EVENING. FRONT HANGS UP ACROSS SRN ZONES SUN AND WASHES OUT ON MONDAY AS ONSHORE WINDS RESUME. SAME GENERAL SYNOPTIC PATTERN SHOULD PERSIST FOR THE UPCOMING WEEK (THOUGH NOT AS AMPLIFIED AS IT CURRENTLY IS) WITH A RIDGE OUT WEST AND EAST COAST TROFINESS. DIFFERENTIAL HEATING & SEABREEZE WILL BE THE MAIN WX PLAYERS - IF THEY CAN OVERCOME THE SUBSIDENCE ALOFT. 20%ERS SHOULD DO TUE-FRI. && AVIATION: UNCERTAINTY REGARDING TSTM DEVELOPMENT DESCRIBED ABOVE IS THE MAIN WX ISSUE. WILL JUST HAVE TO WAIT AND SEE IF SOMETHING FIRES TO OUR NORTH. SHOULD IT HAPPEN...BEST SHOT OF TSTMS WILL BE LATE EVENING THROUGH AROUND SUNRISE AHEAD OF THE FRONTAL BOUNDARY. LOCATIONS EAST OF I-45 SHOULD ALSO SEE MORE AREAL COVERAGE. && 47/37 .HGX WATCHES/WARNINGS/ADVISORIES... NONE. && .PRELIMINARY POINT TEMPS/POPS...
