AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 333 AM CDT THU AUG 19 2004 .DISCUSSION... MUCH OF WEST CENTRAL TX...WITH THE EXCEPTION OF THE NORTHERN EDWARDS PLATEAU...EXPERIENCED A DECENT RAIN EVENT WEDNESDAY AFTERNOON INTO THIS MORNING. THE EVENT BEGAN WHEN A VIGOROUS MID LEVEL SHORTWAVE TROF THAT INTERACTED WITH RAPIDLY DESTABILIZING AIRMASS. AT 08Z...KSJT RADAR INDICATED AN MCS EAST OF A SAN ANGELO TO SWEETWATER LINE...MOVING NORTHEAST AROUND 25 KTS. THERE APPEARED TO BE A WEAK MESOSCALE VORTICITY MAX OVER SAN SABA COUNTY. FURTHER WEST...MOSTLY CLEAR SKIES PREVAILED FROM THE TRANS-PECOS INTO SOUTHEAST NEW MEXICO. PRIMARY FORECAST CONCERN REMAINS RAIN CHANCES. THE GFS MODEL CONTINUES TO SHOW LITTLE RUN TO RUN CONSISTENCY...WHICH COMPLICATES THE OUTER PERIOD FORECASTS IN PARTICULAR. GOES WATER VAPOR IMAGERY INDICATED A COMPACT CIRCULATION OVER SOUTHWEST AZ...SHEARED EAST SOME BY A UPPER JET MAX CUTTING ACROSS CENTRAL BAJA. FURTHER EAST OVER NM...IT WAS DIFFICULT TO DISCERN ANY SHORTWAVE TROFS EMBEDDED IN THE NEARLY ZONAL UPPER FLOW. FOR TODAY...EXPECT THUNDERSTORM COVERAGE TO BE ISOLATED ONCE THE MCS LIFTS EAST OF THE FORECAST AREA. PRIMARY DRIVER FOR RAIN CHANCES TODAY WILL BE LOW LEVEL DESTABILIZATION. ISOLATED THUNDERSTORMS ACTIVITY SHOULD DECREASE WITH BOUNDARY LAYER COOLING DURING THE EVENING. A WEAK FRONT THAT HAD ENTERED THE NORTHERN TX PANHANDLE EARLY THIS MORNING WILL LIKELY SAG INTO THE BIG COUNTRY OVERNIGHT. THE GFS MODEL PROGS A SHORTWAVE TROF TO DIVE INTO THE THE TX PANHANDLE LATE THIS EVENING...WHICH WILL LIKELY HELP SUSTAIN THUNDERSTORMS NEAR THE FRONT INTO THE OVERNIGHT HOURS. WITH THIS IN MIND...WILL PLAN CHANCE CATEGORY POPS FOR THE BIG COUNTRY TONIGHT..WITH LOWER POPS FURTHER SOUTH AWAY FROM THE MID LEVEL SHORTWAVE AND SURFACE FRONT. AS MENTIONED EARLIER...THE GFS APPEARS TO BE STRUGGLING WITH CONSISTENCY WITH RESPECT TO NEXT WEEK/S UPPER PATTERN...ESPECIALLY UPSTREAM OF TX. THE UPPER TROF THAT WAS PROGGED YESTERDAY TO DROP INTO THE GREAT BASIN BY MIDWEEK IS NOW PROGGED TO CUT-OFF AND MEANDER OFF THE SOUTHERN CA COAST. THIS HAS SIGNIFICANT IMPLICATIONS FOR WEST CENTRAL TX WEATHER NEXT WEEK...WITH THE NEW SOLUTION RESULTING IN A MORE PERSISTENT UPPER RIDGE OVER NM AND WEST TX... RATHER THAN THE SOUTHWEST MONSOONAL FLOW OVER TX FROM YESTERDAY/S GFS RUN. IT SHOULD BE NOTED THAT THE NEW ECMWF MODEL RUN IS MORE IN LINE WITH YESTERDAY/S GFS RUN. WILL TRIM WHAT WERE SLIGHT CHANCE POPS FOR NEXT WEEK...AND WARM TEMPS SLIGHTLY...THROUGH NOT TO THE EXTENT AS SUGGESTED BY THE GFS MEX GUIDANCE. && .PRELIMINARY POINT TEMPS/POPS...
