AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 153 PM CDT THU JUL 8 2004 .DISCUSSION... MAIN CONCERN IS POTENTIAL FOR SEVERE WEATHER TONIGHT. IN THE SHORT TERM...INGREDIENTS COMING TOGETHER ACROSS THE PLAINS THIS AFTERNOON FOR ACTIVE WEATHER IN THE CWA OVERNIGHT. LATEST SPC DAY 1 SEEMS TO HAVE MOVED THE MDT RISK AREA FARTHER INTO OUR CWA. GREATEST INSTABILITY THIS AFTERNOON FOUND JUST SOUTH OF A NEARLY STATIONARY WARM FRONT HUGGING THE NEB/KS BORDER. A MOIST ENVIRONMENT PLUS BREAKING CLOUDS WERE ALLOWING MLCAPES TO EXCEED 3400 J/KG...WITH THE INSTABILITY AXIS NOSING INTO SOUTHERN SECTIONS OF THE CWA. THE LATEST ETA/GFS/RUC SEEM TO IMPLY LITTLE MOVEMENT OF THE FRONT THRU THIS EVENING. THIS SHOULD FOCUS DEVELOPMENT OF STRONG/SEVERE THUNDERSTORMS PARTICULARLY ALONG AND SOUTH OF I-80...AS DEPICTED BY PROGGED SCP/SIGSVR/SSCTOR RUC PARAMETERS. WILL THEREFORE BUMP UP POPS FROM THE PREVIOUS FCST AND MENTION POSSIBLE SEVERE. THE WARMING TREND GETS UNDERWAY FRIDAY AS THE MODELS BUILD AN UPPER LEVEL RIDGE INTO THE PLAINS AND SOUTHERLY FLOW PREVAILS AT THE LOW LEVELS. MEANWHILE THE MAV AND MET FOCUS HIGHER POPS TO THE EAST OF THE CWA. WILL THEREFORE PULL POPS FROM THE FCST SINCE NO REAL DISTINGUISHING FEATURES STAND OUT TO SUGGEST CONVECTION. WILL LEAVE FCST DRY THRU SATURDAY AS WELL...AS PER LOW MOS POP GUIDANCE. BY SATURDAY NIGHT THOUGH...THE ETA IS ADVERTISING A POTENT MID LEVEL WAVE EJECTING OUT OF THE HIGH PLAINS AND RIDGING OVER THE WEAKENED UPPER LEVEL RIDGE. THE MAV HITS THE DAKOTAS & PARTS OF NE NEB HARD WITH POPS DURING THE OVERNIGHT HOURS. GOING FCST LOOKS REASONABLE WITH SMALL CHANCE NORTH AND SLGT CHANCE SOUTH. OTHERWISE LOOKING DRY AND WARM FROM SUNDAY INTO MOST OF NEXT WEEK. BY THURSDAY...THE GFS SHOWS THE RIDGE RETROGRADING WITH NW FLOW PREVAILING ABOVE. THIS IN TURN ALLOWS A COLD FRONT TO PUSH THRU THE DAKOTAS AND INTO THE PLAINS. WILL HOLD OFF MAKING ANY SIGNIFICANT TEMP CHANGES UNTIL MODELS SHOW SOME CONSISTENCY WITH THIS FEATURE. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...NONE. IA...NONE. && DEE
