TEXAS/OKLAHOMA PANHANDLES AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AMARILLO TX 204 PM CDT FRI AUG 23 2002 ISOLATED TO SCATTERED TS WILL CONTINUE AGAIN THIS AFTERNOON AND TONIGHT. LOOKS LIKE BEST AREA FOR ORGANIZED STORMS WILL BE OVER THE NORTHERN AND ESPECIALLY NORTHEAST ZONES WHERE SURFACE WINDS HAVE BACKED. 80KT 25H JET EXTENDS FROM UTAH WESTWARD TO THE EASTERN PACIFIC PER LATEST RUC MODEL. 12Z ETA WAS PARTIALLY UNAVAILABLE THIS MORNING SO WILL RELY MORE ON THE AVN. STILL LOOKS LIKE WESTERN ZONES WILL TEMPORARILY DRY OUT SATURDAY AFTERNOON BEFORE NEXT COOL FRONT PUSHES THROUGH THE CENTRAL TEXAS PANHANDLE SATURDAY EVENING. THINKING AT THIS POINT IS THAT SATURDAY NIGHT HAS THE BEST POTENTIAL FOR ORGANIZED STORMS NEAR THE BOUNDARY AS THIS FEATURE PUSHES SOUTHWARD. LOOKS LIKE A DRYLINE AND NORTHWEST MID LEVEL FLOW DEVELOPING. WILL HOLD ON TO SLIGHT CHANCE POPS SUNDAY AND SUNDAY NIGHT WITH REMNANTS OF COOL FRONT OVER THE AREA. RIDGE OVER THE SOUTHERN ROCKIES EXPANDS LATE IN THE WEEKEND WITH NORTHWEST FLOW CONTINUING OVER THE PANHANDLES. ALSO SOME INDICATIONS THE NOCTURNAL LOW LEVEL JET WILL RETURN TO THE SOUTHERN HIGH PLAINS EARLY NEXT WEEK. MEDIUM RANGE MODELS SUGGEST ANOTHER COOL FRONT WEDNESDAY NIGHT.
