SOUTH PLAINS AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LUBBOCK TX 225 PM CDT TUE APR 29 2003 DAY ONE... SATELLITE IMAGERY INDICATES AREA OF LIFT CURRENTLY MOVING ACROSS THE MOUNTAINS OF SOUTHWEST TEXAS AS JET ENERGY SLIDES THROUGH THE SOUTHWESTERLY FLOW LOCATED OVER WEST TEXAS. SHOULD SEE THE MIDDLE LEVEL FLOW IMPROVE SLIGHTLY OVER WEST TEXAS. AREA VWPS ALREADY INDICATING WINDS INCREASING TO AROUND 30KT AT 12KFT. THE DRYLINE IS ON THE MOVE EASTWARD AS THIS MIDDLE LEVEL ENERGY APPROACHES. ALREADY SEEING SOME CU OVER THE SOUTHWESTERN CWA BUT IT APPEARS THAT IT IS BEING UNDERCUT BY SOME DRY AIR. DRYLINE SHOULD MOVE JUST EAST OF SILVERTON TO SLATON TO TAHOKA LINE BEFORE MAXIMUM HEATING. BELIEVE THUNDERSTORMS WILL HOLD OFF UNTIL WE GET CLOSE TO THE CONVECTIVE TEMP THAT IS NEAR 84 DEGREES. COULD SEE A SIMILAR SITUATION TO LAST NIGHT WITH ANOTHER MARGINALLY SEVERE EVENT. THE ONE FACTOR THAT IS SLIGHTLY BETTER IS THE MIDDLE LEVEL JET ENERGY THAT IS APPROACHING. WILL CONTINUE THE CHANCE OF SEVERE THUNDERSTORMS FOR THE LOW ROLLING PLAINS AND THE SLIGHT CHANCE OF THUNDERSTORMS ALONG AND NEAR THE CAPROCK. SHOULD SEE A SUNNY DAY ON WEDNESDAY AS THE DRY AIR MOVES FURTHER EAST IN RESPONSE TO A TROUGH MOVING OUT OF THE WESTERN US. APPEARS THAT WE SHOULD ONLY SEE AN INCREASE IN WIND SPEEDS BY THE AFTERNOON. WINDS LOOK TO STAY BELOW ADVISORY LEVELS BUT COULD REACH 20 TO 30 MPH SO WILL INSERT THE WINDY WORDING. LACK OF MOISTURE SHOULD PRECLUDE ANY DEVELOPMENT OF THUNDERSTORMS. RH VALUES MAY DROP LOW ENOUGH TO BE CONCERNED ABOUT A RED FLAG WARNING. STILL SOME QUESTION AS TO HOW HIGH WIND SPEEDS WILL GET IN THE AFTERNOON. WILL HOLD OFF ON A RED FLAG WATCH AND INFORM LATER SHIFTS OF THIS POTENTIAL. FCSTID=MM DAY TWO THROUGH SEVEN... SHORTWAVE TROF OVER THE CENTRAL PLAINS LATE WEDNESDAY WILL CONTINUE TO MOVE EASTWARD WITH NEAR ZONAL FLOW ACROSS THE REGION. A COLD FRONT WILL MOVE THROUGH THE AREA THURSDAY BECOMING QUASI-STATIONARY AND WASHING OUT OVER THE PERMIAN BASIN AND ALONG THE MOUNTAINS OF NEW MEXICO ON FRIDAY. THUS DRY CONDITIONS WEDNESDAY NIGHT THROUGH FRIDAY WITH SLIGHTLY COOLER TEMPERATURES. FLAT UPPER LEVEL RIDGE TO MOVE ACROSS THE REGION FRIDAY NIGHT AS A LOW OFF THE PACIFIC NORTHWEST MOVES SOUTH TO THE SOUTHERN CALIFORNIA COAST BY SATURDAY MORNING. LEE SIDE TROF/DRY LINE DEVELOPING NEAR THE TEXAS NEW MEXICO BORDER SATURDAY MORNING WILL MOVE EASTWARD DURING THE DAY. ALTHOUGH SOME DIFFERENCES IN MODELS ON HANDLING OF SHORTWAVE EJECTING OUT OF SOUTHERN CALIFORNIA INTO THE PLAINS WITH GFS AND CANADIAN MORE PROGRESSIVE. WILL ATTM TREND TOWARD THE GFS WHICH MOVES THE SHORTWAVE ACROSS THE CENTRAL PLAINS ON SUNDAY. WITH DRY LINE IN PLACE AND TROF MOVING ACROSS THE REGION WILL CONTINUE SLIGHT CHANCE THUNDERSTORMS SATURDAY AND SUNDAY. DRY AGAIN MONDAY AND TUESDAY AS THE SURFACE AND UPPER LEVEL LOWS MOVE TO THE NORTHEAST...ALSO COOLER AS A FRONT MOVES THROUGH THE REGION SUNDAY NIGHT.
