AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 309 PM CDT THU MAY 4 2006 .DISCUSSION... CONGLAMORATION OF DISTURBANCES ALOFT WITH DEEP ISENTROPIC UPGLIDE HAS MAINTAINED AN AREA OF LIGHT TO MODERATE RAIN OVER SOUTHERN MISSOURI THIS AFTERNOON. REGIONAL 88D TRENDS OVER THE PAST FEW HOURS SUGGEST THAT THE BEST FORCING AND LIFT ARE BEGINNING A SHIFT TO THE EAST. THE PRIMARY FORECAST CHALLENGE WILL BE POPS TONIGHT. TONIGHT...LIFT WILL GRADUALLY SUBSIDE FROM NW TO SE AND -SHRA WILL TAPER OFF. HAVE KEPT LIKELY POPS OVER SOUTH CENTRAL MO THIS EVENING...DECREASING TO LOW CHC AFTER MIDNIGHT. HAVE CANCELLED THE FLASH FLOOD WATCH. EMBEDDED MODERATE SHOWERS WILL MAINTAIN A LOW RISK OF LOCALIZED FLOODING...BUT THE OVERALL RISK HAS GREATLY DIMINISHED OVER THE PAST FEW HOURS AND RAINFALL WILL CONTINUE TO DIMINISH THROUGH THIS EVENING. CLOUDS AND NORTHERLY FLOW WILL BE THE RULE FOR THE REMAINDER OF THE OVERNIGHT WITH TEMPS SLOWLY FALLING THROUGH THE 50S. FRIDAY AND SATURDAY...PREDOMINATELY DRY DAY EXPECTED FRIDAY... ALTHOUGH CLOUDY CONDITIONS WILL REMAIN. GIVEN EXPECTED 925MB TEMPS...HIGHS SHOULD REACH THE LOWER/MIDDLE 60S. ISENTROPIC UPGLIDE (305-310K LEVELS) INCREASES ACROSS THE REGION FRIDAY NIGHT INTO SATURDAY AND WILL BRING ANOTHER OPPORTUNITY OF SHOWERS FOR MAINLY THE SOUTHERN HALF OF THE AREA. TEMPS WILL RANGE FROM AROUND 50 AT NIGHT TO THE MIDDLE 60S DURING THE DAY. SATURDAY NIGHT AND SUNDAY...OPTIMISTICALLY LOOKING TO A DRY DAY ON SUNDAY. SHORTWAVE RIDGING WILL BRIEFLY BUILD INTO THE REGION... RESULTING IN PARTLY CLOUDY CONDITIONS AND TEMPS RANGING FROM THE MID/UPPER 40S SAT NIGHT TO THE UPPER 60S ON SUNDAY. IN THE EXTENDED...MONDAY THROUGH THURSDAY...CONSISTENCY ISSUES SIMILAR TO YESTERDAY REMAIN ENTRENCHED IN TODAYS FORECAST. GFS ENSEMBLE SPREAD INCREASES A GREAT DEAL FOR THE FIRST HALF OF NEXT WEEK. THE OPS GFS IS CLOSE TO THE ENS MEAN...HOWEVER THE UKMET/ECWMF HAVE A DIFFERENT SLANT ON THE SPEED OF THE UPPER PATTERNS EVOLUTION. THE CULPRIT REVOLVES AROUND THE HANDLING OF A TROUGH OVER THE WESTERN CONUS AND WHETHER OR NOT IT WILL PHASE WITH ENERGY OVER THE SW CONUS. THE GFS DOES NOT PHASE THESE TWO FEATURES AND RESULTS IN A WEAKER/FASTER TROUGH TO EXIT THE WEST. THE UKMET/ECMWF PHASE THESE FEATURES...RESULTING IN A SLOWER/STRONG TROUGH. WHEN THE UKMET/ECMWF AGREE...IT USUALLY WISEST TO SIDE WITH THAT SOLUTION AND HAVE DONE SO WITH THIS PACKAGE. THE END RESULT IS A WARMING TREND FOR THE PERIOD...BACK TO AROUND AVERAGE. IMPULSES ROTATING AROUND THE WESTERN TROUGH WILL KEEP THE AREA UNSETTLED...HOWEVER TIMING THESE FEATURES IS A RATHER FUTILE EXERCISE. THUS HAVE MAINTAINED CHC POPS FROM MONDAY THROUGH WED NIGHT. GAGAN && .AVIATION... FOR THE 12Z TAFS...PLAN TO ADD PREDOMINANT RAIN WITH TEMPO THUNDER THROUGH MUCH OF THE DAY...ROUGHLY UNTIL 22Z. SURFACE WINDS WILL PREVAIL FROM THE NORTHEAST...ALTHOUGH THEY WILL BECOME A LITTLE CHAOTIC WHEN SHOWERS/STORMS ARE NEAR THE AIRPORT. CEILINGS WERE DROPPING TO LOW END IFR EARLIER BUT SEEMED TO HAVE LEVELED OUT FROM HIGH IFR TO LOWER MVFR. WILL BE KEEPING A CLOSE EYE ON TRENDS TO MAKE LAST MINUTE ADJUSTMENTS BEFORE 12Z ISSUANCE. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. WFO SGF
