AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 334 PM CDT SUN AUG 26 2007 .DISCUSSION... SHORT RANGE (TONIGHT THROUGH TUESDAY NIGHT)... MAIN CONCERN FOR THE SHORT TERM IS WITH HOW WARM TO GO WITH THE AFTERNOON HIGH TEMPERATURES ON MONDAY AND TUESDAY...AND INITIAL TIMING OF PRECIPITATION WITH FRONT TUESDAY NIGHT. OVERALL UPPER PATTERN WILL REMAIN PRETTY MUCH THE SAME THROUGH THIS TIME PERIOD WITH A BROAD WEST TO EAST ORIENTED RIDGE AXIS OVER THE SOUTHERN HALF THE COUNTRY AND A BROAD TROUGH OVER THE NORTHERN HALF. INITIALLY THIS WILL KEEP FORECAST AREA STUCK IN THE MIDDLE...WITH MAIN CONVECTION ACTIVITY WELL TO THE NORTH AND SOUTH OF THE FORECAST REGION. ONE MINOR FLY IN THAT SCENARIO WOULD BE IF ANY CONVECTION CAN KICK OFF OVERNIGHT ACROSS IOWA AS A WEAK UPPER WAVE MOVES ACROSS THE REGION WITH 310K WRF AND GFS BOTH SHOWING SOME BETTER ISENTROPIC LIFT ACROSS THAT REGION. NOT TOTALLY OUT OF THE QUESTION EXTREME NORTHERN MISSOURI COULD GET CLIPPED BY THIS ACTIVITY...BUT CONFIDENCE TOO LOW TO ADD POPS AT THIS POINT. UPPER RIDGE STRENGTHENS ACROSS MISSOURI ON MONDAY. SOUTHERLY WINDS SHOULD BE A LITTLE STRONGER ACROSS THE FORECAST AREA AS A SURFACE TROUGH SETS UP FROM EASTERN SOUTH DAKOTA INTO NORTHWEST KANSAS. TEMPERATURES THAT WERE IN THE LOWER TO MIDDLE 90S OVER KANSAS TODAY SHOULD BE PULLED FURTHER EAST WITH THIS FLOW...ALLOWING MOST IF NOT ALL THE FORECAST AREA TO REACH INTO THE 90S ON MONDAY. TUESDAY TEMPERATURES IN NORTHERN AREAS MAY BE TEMPERED A BIT BY ANY CLOUDINESS MOVING INTO THE REGION...AND SOUTHERLY WINDS SHOULD BE LIGHTER AS SURFACE BOUNDARY APPROACHES NORTHERN MISSOURI. STILL...WITH AREA ON THE WARM SIDE OF THIS BOUNDARY...EXPECT TO SEE TEMPERATURES STILL SLIGHTLY ABOVE NORMAL FOR AFTERNOON HIGHS. WITH THE SURFACE BOUNDARY MOVING INTO THE FORECAST AREA TUESDAY NIGHT...AND A SMALL WAVE DEVELOPING ALONG THE SOUTHERN EDGE OF THE NORTHERN STREAM...SHOULD SEE CONVECTION DEVELOPING IN SOUTHEAST NEBRASKA TUESDAY AFTERNOON AND HEADING INTO THE FORECAST AREA TUESDAY NIGHT. CURRENT THINKING IS THIS WAVE WILL BE SLOW TO PROGRESS TO THE EAST AS IT AWAITS A PUSH FROM STRONGER WAVE DROPPING INTO THE UPPER MIDWEST BY 12Z WEDNESDAY...THUS WILL FOCUS THE BETTER CHANCES OF RAIN ACROSS THE NORTHWEST HALF OF THE FORECAST AREA TUESDAY NIGHT. PC MEDIUM RANGE (WEDNESDAY THROUGH SUNDAY)... MEDIUM RANGE MODELS CONTINUE TO BE IN VERY GOOD AGREEMENT WITH REGARD TO THE OVERALL HEMISPHERIC SYNOPTIC PATTERN...HOWEVER SUBTLE DIFFERENCES ON THE SUBSYNOPTIC SCALE...PARTICULARLY IN THE OPERATIONAL 12Z GFS RUN...LEAD TO THE PRIMARY UNCERTAINTY THIS FORECAST CYCLE. SFC FRONT STILL APPEAR ON TAP TO MOVE THROUGH THE FORECAST AREA ON WEDNESDAY...HOWEVER THE LATEST GFS RUN DELAYS THE PROGRESSION OF THE LAGGING H8 FRONT...AS WAVE ENERGY ROTATING ABOUT THE UPPER LOW CENTERED OVER HUDSON BAY IS FORECAST TO BE MORE DAMPENED AND SHEARED THAN PREVIOUS FORECASTS. AS A RESULT...LOW LEVEL PRESSURE RISES NORTH OF THE FRONT ARE FORECAST TO BE NOT AS STRONG AS PREVIOUSLY ANTICIPATED...AND RESIDUAL MOISTURE ABOVE THE SFC IS NOT SCOURED SOUTH AS FAST AS PREVIOUS RUNS HAD DEPICTED. IN ADDITION...OPERATIONAL 12Z GFS KEEPS THE ELEVATED BAROCLINIC ZONE CENTERED CLOSER TO THE FORECAST AREA...WITH SEVERAL RIPPLES OF ENERGY PROGRESSING IN THE NW FLOW ALOFT HELPING FORCE VERY WEAK ISENTROPIC LIFT. WILL DISCOUNT THIS LATEST GFS RUN FOR THE TIME BEING AS GFS ENSEMBLES CONTINUE TO SHOW STRONGER PRESSURE RISES DEVELOPING OVER THE WRN GREAT LAKES...FORCING A DRIER AIRMASS THROUGH THE FORECAST AREA. GFS ENSEMBLES HAVE AGREEMENT FROM THE 00Z ECMWF...IN ADDITION TO CONCEPTUAL MODELS WHICH WOULD ARGUE FOR A DRYING OF THE ATMOSPHERIC COLUMN WITH DEEPENING NELY LOW LEVEL FLOW. ALSO...SUBJECTIVE ANALYSIS OF THE OPERATIONAL GFS ISENTROPIC FIELDS INDICATES ONLY A NARROW ZONE OF VERY WEAK ISENTROPIC LIFT WITH INCREASING DOWNGLIDE IN THE DRYING LAYER TO THE NORTH. THEREFORE...HAVE SERIOUS RESERVATIONS OVER THE OPERATION GFS PRECIPITATION FIELD FORECASTS BEYOND WED NIGHT. THUS...HAVE KEPT A MAINLY DRY FORECAST FOR THURS AND INTO THE WEEKEND DESPITE THE OPERATIONAL GFS DEPICTION OF LIGHT PRECIP ECHOES IN AND AROUND THE FORECAST AREA. GIVEN THE ABOVE THINKING...HAVE FORECAST A COUPLE DEGREES BELOW MEX GUIDANCE NUMBERS...PARTICULARLY FOR LOW TEMPS WHERE DRIER AND CLEARER OVERNIGHTS ARE ANTICIPATED. THIS SHOULD YIELD CONDITIONS VERY NEAR CLIMATOLOGICAL AVERAGES FOR THE END OF AUGUST/BEGINNING OF SEPTEMBER. IF FOR SOME REASON THE OPERATIONAL GFS DID COME TO FRUITION...OVERALL AVERAGE TEMPERATURES WOULD REMAIN SIMILAR...ALTHOUGH DIURNAL SPREADS WOULD NEED TO BE REDUCED. 21 && .AVIATION... /1225 PM CDT SUN AUG 26 2007/ FOR 18Z TAFS...RUC MODEL SHOWS A WEAK VORT MAX ASSOCIATED WITH CURRENT CLOUDS AND ISOLATED CONVECTION IN EASTERN KANSAS. ALSO RUC CONTINUES TO SHOW SOME WEAK ISENTROPIC LIFT ON THE 310K SURFACE ON INTO THE AFTERNOON HOURS. THIS IS LIKELY WHY THE SHOWERS HAVE REDEVELOPED IN THE ATCHISON COUNTY KANSAS AREA LATE THIS MORNING. EXPECT THIS DEVELOPMENT WILL STAY ISOLATED DUE TO THE LACK OF DEEP MOISTURE. GIVEN TRACK OF CURRENT SHOWERS...SHOULD STAY NORTH OF KMCI AND SOUTH OF KSTJ. WILL HANDLE WITH VC WORDING FOR NOW AND WATCH FOR ANY ADDITIONAL DEVELOPMENT. PC && .EAX WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE.
