AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 1131 PM CDT SUN JUN 14 2009 ...UPDATED AVIATION DISCUSSION... .DISCUSSION... INCREDIBLY CHALLENGING FCST ONCE AGAIN TODAY...AS A RATHER TURBULENT PATTERN CONTINUES TO BE POORLY RESOLVED IN MODEL GUIDANCE. WV IMAGERY THIS AFTN NEARLY A CARBON COPY OF YESTERDAY...WITH SEVERAL PV ANOMALIES PRESENT. THIS AFTN HAS ACTUALLY HELD TO BE A VERY NICE DAY AS SMALL SCALE RIDING ALOFT HAD KEPT THE AREA VOID OF PRECIP. AT THE SFC...WHILE MULTIPLE CONVECTIVE SYSTEM HAVE LEFT MAP MUDDLED...BECOMING MORE EVIDENT THAT THE TROUBLESOME STATIONARY BOUNDARY IS NOW TRYING TO FOCUS SLIGHTLY FURTHER NORTH THAN YESTERDAY AFTN DUE TO DIFFERENTIAL HEATING BY LOW-LVL CLOUDS...LIKELY ALONG KS/OK BORDER SE INTO NWRN ARKANSAS. MAIN FCST CHANGES WERE TO TRY TO FINE TUNE POPS/TEMPS OVERNIGHT AND ON MONDAY. IF THE ANSWER WAS WRITTEN ON THE WALLS FOR THIS FCST...IT MUST BE IN INVISIBLE INK AS MODELS CONTINUE TO HAVE LARGE SCALE DIFFICULTIES RESOLVING BOTH PV ANOMALIES...LOW-LVL MOISTURE...AND WITH THE UNCERTAINTY IN SFC FEATURES LOCATION OF HIGHEST QPF. THIS BEING SAID...LAST NIGHTS PV ANOMALY HAS SUPPRESSED BROAD MID-LVL RIDGING TODAY WHICH SHOULD ALLOW FUTURE DISTURBANCES TO TRAVEL FURTHER E AND S THAN NE AS HAPPENED LAST NIGHT. FIRST DISTURBANCE LIFTING OUT OF THE FOUR CORNERS REGION IS ALREADY PRODUCING CONVECTION AND WILL PRODUCE ADDITIONAL CONVECTION OVER WESTERN KS/OK LATE THIS AFTN AND EVE. SECOND DISTURBANCE JUST OFF THE BAJA COASTLINE WILL BE THE SYSTEM WE WILL NEED TO WATCH AS IT WILL HAVE A HIGHER PROB OF PRODUCING ADDITIONAL MCS ACTIVITY FURTHER S AND IS BETTER TIMED WITH AN INCREASING LLJ AFTER MIDNIGHT. 12Z ECMWF CONTINUES TO HAVE THE BEST HANDLE ON THIS SETUP WITH THE LIKELIHOOD OF SEVERAL CLUSTERS OF MCS DEVELOPING LATE THIS EVE. THESE SYSTEMS SHOULD PROGRESS ALONG 850 MB THETA-E AXIS TO OUR SOUTH AND ALONG STALLED FRONT ALSO TO OUR SOUTH. CURRENTLY FEEL HIGHEST QPF WILL FALL ALONG SOUTHERN KS...NORTHERN OK AND INTO SOUTHERN MO PERHAPS WITH A SECOND AREA FURTHER NW INTO NE. SHOULD ANY AREA BE SUSCEPTIBLE TO HEAVY RAIN IT WOULD BE AREAS FROM KANSAS CITY SOUTHWARD. HOWEVER GIVEN THE LIKELIHOOD OF SEVERAL CLUSTERS...NO ONE DEFINED AREA OTHER THAN ALONG THE BOUNDARY HAS A HIGHER PROBABILITY THAN ANYWHERE ELSE. IN ADDITION TO MCS...BROAD ISENTROPIC LIFT SHOULD BE STRONG ENOUGH TO PRODUCE SEVERAL WAA WINGS OF PRECIP TOWARDS DAYBREAK IN THE WESTERN CWA AHEAD OF THIS MCS ACTIVITY. AS MENTIONED THIS MORNING...ADDITIONAL CONCERNS FOR RENEWED AFTN CONVECTION CONTINUE AS SFC FRONT SHOULD TRY TO ARCH NORTHWARD INTO THE CWA ON MON. EXPECTING SKIES TO CLEAR MUCH LIKE THIS AFTN WITH PARTLY SUNNY SKIES POSSIBLE EARLY AFTN. TEMPS WILL BE VERY DIFFICULT...FOR NOW FEEL MOST CLOUD COVER WILL BE IN NORTHERN MO KEEPING MID-UPR 70S IN THOSE AREAS. FURTHER SOUTH...SHOULD SKIES SCATTER LOW TO EVEN MID 80S MAY BE POSSIBLE. WITH THESE WARM TEMPS...MUCAPE PLOTS BEGIN TO EXCEED 2000 J/KG WITH ONLY A WEAK EML. ABSENT OF A WAVE ALOFT...WILL NEED TO WATCH OUTFLOW BOUNDARIES ESPECIALLY IN AREAS SOUTH OF INTERSTATE 70. STILL VERY UNCERTAIN TO SAY THE LEAST. WITH THE FRONT FURTHER NORTH ON MONDAY...MCS DEVELOPMENT REGION WILL BE MUCH CLOSER THAN TODAY. SHOULD AFTN CONVECTION DEVELOP IT WOULD MOST LIKELY FORM INTO AN MCS...WITH ADDITIONAL ACTIVITY LIKELY THROUGH THE NIGHT AS LLJ BECOMES MORE OF A PLAYER. DUE TO CONTINUED UNCERTAINTIES AND THE LACK OF HEAVY RAIN LAST NIGHT...WILL HOLD OFF ON A FFA FOR TONIGHT. LOCALLY HEAVY RAIN WILL STILL BE POSSIBLE AND EVEN LIKELY...HOWEVER PINPOINTING A CERTAIN AREA REMAINS FAR TO DIFFICULT. RIGHT NOW...WORRIED ABOUT MONDAY EVE AND NIGHT GIVEN A FURTHER NORTH FRONT AND BUILDING INSTABILITY. WILL CONTINUE TO HIGHLIGHT IN AN ESF. FINAL SYSTEM SHOULD EXIT ON TUESDAY MORNING...HOWEVER CAP REMAINS FAIRLY WEEK AND COULD NOT RULE OUT REDEVELOPMENT IN THE AFTERNOON. DUX MEDIUM RANGE (WED-SAT)... MADE A FEW ADJUSTMENTS TO THE MEDIUM RANGE FORECAST. EC/GFS ARE IN GENERAL AGREEMENT WITH OVERALL PATTERN. RIDGE BUILDS IN WEDNESDAY INTO THURSDAY. EXPECT AFTERNOON HIGHS ON WEDNESDAY TO BE MAINLY IN THE UPPER 80S WITH LOW 90S POSSIBLE IN EAST CENTRAL KANSAS AND WEST CENTRAL MISSOURI. AS THE RIDGE CONTINUES TO BUILD FOR THURSDAY...HIGHS SHOULD BE A FEW DEGREES WARMER. INTRODUCED CHANCE POPS TO THE FORECAST AREA THURSDAY NIGHT INTO FRIDAY. EC/GFS BOTH PROG A DECENT STRENGTH WAVE TO BREAK DOWN THE RIDGE AND MOVE ACROSS THE REGION AT THAT TIME. IN ADDITION TO THE PRECIP...THIS SYSTEM SHOULD ALSO KNOCK AT LEAST A FEW DEGREES OFF MAX TEMPS. FOR NOW JUST TRENDED DOWN A FEW DEGREES FOR TEMPS ON FRIDAY. LATER SHIFTS MAY NEED TO ADJUST FURTHER. KEPT REMAINDER OF MEDIUM RANGE DRY. EXPECT MAX TEMPS TO CONTINUE TO BE AT LEAST A FEW DEGREES ABOVE NORMAL THROUGH THE WEEKEND...AS THE RIDGE ONCE AGAIN BUILDS BACK IN. 33 && .AVIATION... FOR THE 06Z TAFS...BIGGEST CONCERN FOR THIS TERMINAL FCST IS THE POTENTIAL FOR CONVECTION LATE TONIGHT INTO MON MORNING. SFC MOISTURE/INSTABILITY AXIS IS WELL SOUTH OF THE TAF SITES...FM SWRN KS INTO NRN OK/ARK. MODELS ARE LITTLE HELP FOR THE UPCOMING CONVECTIVE SCENARIO...THEREFORE WILL RELY ON PATTERN RECOGNITION. A WEAK SHORTWAVE WAS TRIGGERING SHALLOW CONVECTION JUST NORTH OF STJ. SCT THUNDERSTORMS MAY IMPACT KSTJ AS SOON AS 05Z...BUT ACTIVITY WILL GENERALLY BE CONFINED TO THE NORTH OF STJ. OTHERWISE...A SHORTWAVE TROUGH IN THE SRN ROCKIES WILL SHIFT ENE TONIGHT WITH CONVECTION ALREADY DEVELOPING IN WRN/CNTRL. THIS CONVECTION WILL MOVE RAPIDLY EAST TONIGHT AND MERGE WITH ELEVATED CONVECTION WHICH WILL DEVELOP ALONG AND SOUTH OF INTERSTATE 70 JUST BEFORE DAYBREAK. CONVECTIVE DEVELOPMENT SOUTH OF I-70 IS THE RESULT OF MODERATE ISENTROPIC LIFT. THE STRONGEST THUNDERSTORMS ARE EXPECTED TO BE SOUTH OF THE TERMINALS...ALONG THE BETTER ELEVATED INSTABILITY AXIS ABOUT 100-150 MILES TO THE SOUTH OF KMKC. REGARDLESS...ENOUGH INSTABILITY WILL BE AVAILABLE FOR A EXTENDED PERIOD OF CONVECTION DURING THE EARLY MORNING HOURS. HOW LONG THE CONVECTION LASTS IS A TOUGH QUESTION TO ANSWER...BUT WILL PLAY CLIMATOLOGICAL FAVORED SCENARIO. WILL HOLD CONVECTION FOR 4 HOURS...DIMINISHING TO STRATIFORM RAIN LATER IN THE MORNING. GIVEN THE RAIN INTO THE COLD AIR MASS...IFR STRATUS MAY DEVELOP...SIMILAR TO WHICH HAS HAPPENED SEVERAL TIMES THE PAST WEEK. MODELS ALSO SUGGEST THE IFR CIGS BUT THE LATEST NAM IS HOLDING THE CIGS TOO LONG GIVEN IT IS MID JUNE. CONFIDENCE IS NOT HIGH IN THE STRATUS DEVELOPMENT AS SUBSIDENCE BEHIND A CONVECTIVE SYSTEM IS SOMETIMES TOO STRONG FOR STRATUS DEVELOPMENT. ONCE THE CONVECTIVE SYSTEM MOVES EAST...STRONG SOLAR INSOLATION SHOULD RISE CIGS IN THE AFTN. DB && .EAX WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE.

THE THREAT FOR ORGANIZED SEVERE WEATHER IS LOW. A MORE ORGANIZED COMPLEX OF STRONGER THUNDERSTORMS IS EXPECTED TO DEVELOP ACROSS WESTERN AND CENTRAL KANSAS TONIGHT ALONG A STALLED FRONT. THESE THUNDERSTORMS WOULD MOVE EASTWARD INTO THE OUTLOOK AREA BY DAYBREAK MONDAY. BY THE TIME THIS THUNDERSTORM COMPLEX REACHES EASTERN KANSAS...THE THREAT FOR SEVERE WEATHER APPEARS LOW...THOUGH A FEW LARGE HAIL STONES AND/OR DAMAGING WIND GUSTS CANNOT BE RULED OUT AS STORM TRACK EAST SOUTHEAST INTO MISSOURI. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY IF THIS THUNDERSTORM COMPLEX CAN CLEAR EAST OF THE OUTLOOK AREA MONDAY MORNING...AND SUFFICIENT DESTABILIZATION CAN OCCUR WITH DAYTIME HEATING MONDAY AFTERNOON...AN ADDITIONAL SEVERE THREAT MAY PRESENT ITSELF MONDAY AFTERNOON. LARGE HAIL AND DAMAGING WIND GUSTS WOULD BE THE PRIMARY THREATS WITH ANY STORMS THAT MAY FORM MONDAY AFTERNOON WITH AREAS SOUTH OF INTERSTATE 70 HAVING THE HIGHEST PROBABILITY OF THIS OCCURRING. HOWEVER THIS REMAINS HIGHLY UNCERTAIN DUE TO UNKNOWN IMPACTS OF OVERNIGHT STORMS. ANOTHER LARGE COMPLEX OF THUNDERSTORMS IS EXPECTED TO AGAIN DEVELOP ACROSS CENTRAL KANSAS MONDAY NIGHT...AND MOVE INTO THE OUTLOOK AREA BY TUESDAY MORNING. SIMILARLY TO THE PREVIOUS COMPLEX THE NIGHT BEFORE...THE THREAT FOR ORGANIZED SEVERE WEATHER APPEARS LOW...THOUGH A MARGINAL LARGE HAIL AND/OR DAMAGING WIND THREAT IS POSSIBLE. MORE THAN LIKELY...THE GREATEST THREAT FROM ALL THESE THUNDERSTORM COMPLEXES WILL BE THE RISK FOR REPEATED ROUNDS OF HEAVY AND EXCESSIVE RAINFALL...LEADING TO THE POTENTIAL FOR FLOODING. WITH NUMEROUS ROUNDS OF STORMS...AND COPIOUS AMOUNTS OF MOISTURE FOR THESE STORMS TO TAP...THIS WEATHER PATTERN APPEARS VERY FAVORABLE FOR BOTH LOCALIZED FLASH FLOODING AND RIVER FLOODING LATE TONIGHT THROUGH TUESDAY. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION IS NOT ANTICIPATED THROUGH TONIGHT...THOUGH MAY BE NECESSARY MONDAY AFTERNOON. SHOULD HEAVY RAIN MOVE THROUGH THE AREA TONIGHT...SPOTTERS ARE URGED TO REPORT RAINFALL TOTALS. DUX
