AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
141 AM CDT TUE MAR 10 2009
.DISCUSSION...
/752 PM CDT MON MAR 9 2009/
WILL BE ADDING OUR SOUTHERN MOST COUNTIES TO THE FLASH FLOOD WATCH.
AM CONCERNED THAT STORMS DEVELOPING WEST OF WICHITA WILL BE TAKING A
MORE EAST NORTHEAST TRACK AS 850MB WINDS START TO VEER TOWARD
MIDNIGHT WITH THE 850 THETA E AXIS ADVECTING INTO THAT REGION. AT
THIS TIME IT APPEARS FLOODING WILL STILL BE OUR MAIN CONCERN
TONIGHT...ALTHOUGH RUC CAPE AND LI IS SUGGESTING SOME INSTABILITY
TRYING TO MOVE INTO EXTREME SOUTHWEST COUNTIES TOWARD MIDNIGHT....SO
WILL HAVE TO WATCH THE EVOLUTION OF THE STORMS AROUND WICHITA.

.PREV DISCUSSION...
NEAR TERM (THROUGH TONIGHT)...
/330 PM CDT MON MAR 9 2009/
EARLY AFTERNOON SURFACE ANALYSIS SHOWS WARM FRONT (AS INDICATED BY
WIND SHIFT) HUNG NEAR THE MISSOURI OZARKS...THOUGH DRY CONTINENTAL
RETURN FLOW ON THE WRN PERIPHERY OF SFC HIGH PRESSURE HAS LIMITED
BETTER LOW LEVEL MOISTURE RETURN FURTHER TO THE SOUTHWEST ACROSS
CNTRL OKLAHOMA. 12Z SOUNDING DATA FROM KOUN AND KFWD INDICATE +13C
H9-H8 DEWPOINTS COINCIDENT WITH SSWLY 30-40KT WINDS...SUPPORTED BY
CURRENT PROFILER PLOTS. MEANWHILE...WV IMAGERY SHOWS AN EXTENSIVE
SUBTROPICAL PLUME STREAMING AHEAD OF A SIGNIFICANT TROUGH DIGGING
INTO THE INTERMOUNTAIN WEST. A LEAD WAVE HAS BECOME SHEARED THROUGH
THE SUBTROPICAL FEED...YET HAS BEEN SUFFICIENT TO INDUCE
ISENTROPIC UPGLIDE/ELEVATED THETA-E ADVECTION FROM THE SRN PLAINS
ACROSS THE WARM FRONTAL BOUNDARY.
REGIONAL RADAR IMAGERY SHOWS NUMEROUS SHOWERS WITH EMBEDDED ISOLATED
THUNDERSTORMS BLOSSOMING FROM SOUTH CNTRL KANSAS THROUGH CNTRL
MISSOURI...AND AS DEEP MOISTURE FLUX CONTINUES IN THE PRESENCE OF AN
INCREASING LLJ AXIS LATE THIS AFTERNOON...FURTHER UPSCALE GROWTH OF
PRECIPITATION ECHOES CAN BE ANTICIPATED. PARTICULARLY...MORE ROBUST
CONVECTION IS MOST LIKELY FROM SWRN OKLAHOMA THROUGH SRN KANSAS THIS
AFTERNOON IN A MORE UNSTABLE ENVIRONMENT...EVENTUALLY PROPAGATING IN
A MORE ELEVATED REGIME TOWARDS WRN MISSOURI THIS EVENING.
INTERESTINGLY...DESPITE ALL THE HIGHER RESOLUTION AND LOCAL
MODELS...IT SEEMS LIKE THE LOWER RESOLUTION ECMWF HAS HANDLED THE
CURRENT CONVECTIVE TRENDS THE BEST. REGARDLESS...ESSENTIALLY ALL
MODELS INDICATE INTENSE THETA-E ADVECTION CONTINUING THROUGH THE
EVENING AND OVERNIGHT HOURS.
AS FAR AS SEVERE POTENTIAL...AM QUITE SKEPTICAL WHETHER ANY SEVERE
THUNDERSTORMS WOULD BE POSSIBLE IN THE FORECAST AREA. EXTENSIVE
SUBTROPICAL MOISTURE HAS LIMITED H7-H5 LAPSE RATES TO A PALTRY 6
C/KM...WITH NO IMPROVEMENT NOTED UPSTREAM. ALL INSTABILITY MEASURES
ARE CURRENTLY NIL...WITH THE ONLY NOTABLE SB/MLCAPES (1000-1500
J/KG) RELEGATED TO CNTRL/SRN OKLAHOMA. WITH AGGRESSIVE LIFT AND
CONVECTIVE DEVELOPMENT ALONG AND NORTH OF THE WARM FRONT MOST LIKELY
REINFORCING THE BAROCLINIC BOUNDARY...THE PROBABILITY OF MORE
ORGANIZED SEVERE ACTIVITY PROGRESSING THIS FAR NORTH APPEARS QUITE
LOW.
OTHERWISE...BIGGEST THREAT CLEARLY LOOKS TO BE EXCESSIVE RAINFALL.
FLASH FLOOD WATCH WILL REMAIN IN EFFECT...AS MANY FACETS NECESSARY
FOR EXCESSIVE RAINFALL APPEAR TO BE COMING TOGETHER NICELY. FORECAST
SOUNDINGS ALL INDICATE PWATS ABOVE 1.25 INCHES...WITH SREF PWAT
FORECASTS IN EXCESS OF 3 NORMALIZED STANDARD DEVIATIONS ABOVE
AVERAGE (ABOVE THE 90TH PERCENTILE FOR MARCH). THE DEEP MOISTURE
FETCH WITH BOUNDARY AND LLJ TRAJECTORIES REMAINING PARALLEL TO MEAN
WIND VECTORS SUGGESTS HEAVY RAINFALL BECOMING VERY LIKELY. SEE
HYDROLOGY SECTION BELOW FOR MORE DETAILS.

TUESDAY AND WEDNESDAY:
BIGGEST CHALLENGE DEALS WITH TEMPERATURES FOR TUESDAY. 12Z NAM
PUSHES A STRONG COLD FRONT THROUGH THE FORECAST AREA BY 18-21Z. THIS
HAS SOME SUPPORT FROM THE 00Z ECMWF. THE GFS IS A BIT SLOWER THAN
THE OTHER TWO MODELS. PREFERENCE WAS TO GO A LITTLE BIT FASTER THAN
THE GFS BUT NOT QUITE AS FAST AS THE NAM. THINKING THAT CONVECTION
TONIGHT MAY HANG THE COLD FRONT A BIT SO A BLEND SEEMED REASONABLE.
NONETHELESS...COOLED TEMPERATURES DOWN ABOUT 5 DEGREES IN THE
NORTHWEST PORTION OF THE CWA. THAT AREA MAY BE LUCKY TO REACH THE
UPPER 30S AS THE COLD FRONT SHOULD PASS THEM BY 12Z. FORECAST
CONFIDENCE IS LOW FOR HIGH TEMPERATURES ELSEWHERE IN THE CWA.
EASTERN ZONES WILL WARM UP NICELY...APPROACHING 70 DEGREES...AHEAD
OF THE FRONT. SURFACE DEWPOINTS SHOULD TOP OUT IN THE MIDDLE TO
UPPER 50S AND COMBINED WITH THE WARMER TEMPERATURES...WITH THE FRONT
MOVING THROUGH...A FEW THUNDERSTORMS ARE POSSIBLE. WINDS ARE VEERED
SOUTHWESTERLY AND MUCAPES ARE ON THE ORDER OF 500 TO 900 J/KG. THIS
DOESNT SEEM FAVORABLE FOR SEVERE STORMS BUT THERE IS AMPLE LOW LEVEL
SHEAR TO COMPENSATE. SHOULD ANY STRONGER STORMS DEVELOP THEY WILL
RACE EASTWARD AND BE OUT OF OUR EASTERN ZONES QUICKLY. OUTSIDE OF
TEMPERATURES FORECAST CONFIDENCE IS MEDIUM FOR TUESDAY.
MUCH COLDER AIR WILL MOVE INTO THE REGION OVERNIGHT AND WEDNESDAY.
LOWS WILL BE WELL BELOW NORMAL...RANGING FROM THE LOWER TEENS
NORTHWEST TO THE MIDDLE 20S SOUTHEAST. COLD HIGH TEMPERATURES OF 15
TO 20 DEGREES BELOW NORMAL ARE EXPECTED AS THE STRONG SURFACE HIGH
PRESSURE MOVES INTO THE NORTHERN PLAINS/UPPER MIDWEST. THIS STRONG
HIGH PRESSURE WILL KEEP THINGS DRY. FORECAST CONFIDENCE IS HIGH FOR
WEDNESDAY.
CDB
MEDIUM RANGE (THURSDAY THROUGH MONDAY)...
MODELS CONTINUE TO ADVERTISE A SPLIT FLOW REGIME ACROSS THE PLAINS
WITH MODELS DEPICTING A WEAK SRN BRANCH UPPER TROUGH OVER THE SRN
ROCKIES AND DESERT SW THURSDAY THROUGH SUNDAY. GFS/ECMWF ENSEMBLES
HAVE OFFERED LITTLE CONFIDENCE ON HOW FAR NORTH THE CONFLUENT ZONE
BTWN THE TWO BRANCHES WILL EXIST. MODELS HAVE BEEN TRENDING FURTHER
NORTH WITH TIME BUT WITH WEAK SHORTWAVES EMBEDDED IN WEAK FLOW
ALOFT...FIND LITTLE REASON TO DIVERT FM CURRENT DRY FCST. WOULD NOT
BE SURPRISED THAT A PERIOD OF LIGHT PRECIP WILL OCCUR SOMEWHERE IN
THE FRIDAY TO SUNDAY TIME FRAME...BUT CONFIDENCE IN ANY PARTICULAR
DAY IS LOW. OTHERWISE...WILL CONTINUE TO THE SLOW WARMING
TREND...BUT NATURALLY ANY CLOUD COVER AND PRECIP WILL HAVE A MAJOR
IMPACT.
FOR MONDAY...ENSEMBLES ONCE AGAIN OFFER LITTLE CONFIDENCE IN THE
LOCATION AND INTENSITY OF THE NEXT UPPER TROUGH TO DIG INTO THE
PLAINS OR ROCKIES. HAVE INTRODUCE A SLIGHT CHC OF PRECIP FOR MONDAY
FOR NOW UNTIL SCENARIO BECOMES MORE CLR.

.HYDROLOGY...
AS STATED ABOVE...MAIN CONCERN LATE THIS AFTN THROUGH TUESDAY
MORNING WILL BE WITH HYDROLOGY AS MODELS ARE INSISTENT IN SURGING
PWAT VALUES IN EXCESS OF 1.25 INCHES ALL THE WAY UP TO THE IOWA
BORDER. STRONG THETA-E CONVERGENCE IS EXPECTED TO PIN ITSELF ALONG
A DEVELOPING 850MB STATIONARY FRONT THIS EVENING. WITH THE
INFLUENCE OF AN INCREASING LLJ AND A CHAIN OF WEAK EMBEDDED S/W IN
THE MEAN FLOW...APPEARS LIKELY THAT SOME AREAS WILL RECEIVE 1-3
INCHES OF RAIN THROUGH TUESDAY MORNING (AND NOT OUT OF THE QUESTION
FOR LOCALIZED HIGHER ACCUMULATIONS). OF MORE CONCERN...MUCH LIKE
SATURDAY NIGHT...850-700 MB MOISTURE TRANSPORT VECTORS REMAIN
FOCUSED ON AREAS WHICH RECEIVED UPWARDS (OR IN EXCESS OF) 2 INCHES
OF RAIN IN THE PAST 48 HOURS.
IN ADDITION...SEVERAL RIVER POINTS REMAIN IN FLOOD...WHILE OTHERS
HAVE BEEN PUSHED AOA THE 75TH PERCENTILE FOR THIS TIME OF YEAR (MANY
OF WHICH ARE ABOVE THE 95TH PERCENTILE). ANY ADDITIONAL RAIN IN
THESE BASINS WILL ALMOST ASSUREDLY BE ENOUGH TO PUSH RIVERS WHICH
DIDNT FLOOD SUNDAY...TO REACH FLOOD LEVELS BY TUESDAY. VIRTUALLY ALL
SMALLER BASINS WILL BE SUSCEPTIBLE TO AT LEAST MINOR FLOODING...WITH
EVEN LARGE BASINS POSSIBLY REACHING FLOOD LEVELS AFTER THE EVENT.
GIVEN THE LOW FFG AND EXPECTED QPF...THE FLASH FLOOD WATCH WILL
REMAIN IN EFFECT FOR THE MAJORITY OF THE AREA. INITIALLY BIGGEST
QUESTIONS AND LOWEST CONFIDENCE REMAINS ON THE EXTREME SOUTHERN
PORTIONS OF THE WATCH...WHERE ONLY A FEW TENTHS OF AN INCH OF RAIN
HAS FALLEN SINCE SAT. HOWEVER...RECENT MODEL AND OBSERVATIONAL
TRENDS SEEM TO INDICATE THE DISTINCT POSSIBILITY OF BANDED HEAVIER
PRECIPITATION ALIGNING CLOSER TO CNTRL MISSOURI (MORE CLOSELY TIED
TO THE WARM FRONT)RATHER THAN ALONG THE IOWA BORDER.
DUX/21

.AVIATION...
FOR THE 06Z TAFS...RAIN HAS ENDED IN KSTJ AND WILL SHORTLY AT KMCI
AND KMKC. BOUNDARIES MAKING IT DIFFICULT TO PIN DOWN TIMING OF WIND
SHIFTS. COLD FRONT LIES FROM CENTRAL IA THROUGH NORTHWEST MO...JUST
NORTH OF KSTJ...THROUGH SOUTHWEST KS. ONCE WINDS SWITCH TO A
NORTHERLY COMPONENT EXPECT IFR CEILINGS WITH LIGHT FOG. TOWARDS
DAYBREAK POTENTIAL EXISTS FOR LIFR CEILINGS AT BOTH KMCI AND KSTJ.
CEILINGS WILL IMPROVE SLOWLY TO MVFR BY LATE MORNING. SURFACE
PRESSURE GRADIENT WILL TIGHTEN THIS MORNING RESULTING IN GUSTY
NORTHWEST WINDS WHICH WILL LAST THROUGH THE AFTERNOON. SHOULD SEE
RAPID CLEARING AROUND SUNSET AS STRONG SUBSIDENCE OF DRIER AIR
ERODES CLOUD DECK.

SHOWERS AND EMBEDDED THUNDERSTORMS HAVE ALREADY DEVELOPED ACROSS SOUTHERN KANSAS...AND WILL MOVE INTO MUCH OF THE OUTLOOK AREA THIS AFTERNOON. IF INSTABILITY MEASURES CAN INCREASE RAPIDLY LATE THIS AFTERNOON AND EVENING...A FEW SEVERE THUNDERSTORMS MAY BE POSSIBLE IN ANY STRONGER STORMS...GENERALLY SOUTH OF THE MISSOURI RIVER...WITH HAIL THE PRIMARY THREAT. AN ISOLATED TORNADO CANNOT BE RULED OUT...HOWEVER WOULD BE VERY UNLIKELY. A MUCH MORE SIGNIFICANT THREAT WILL BE EXCESSIVE RAINFALL AND FLOODING THIS EVENING THROUGH THE OVERNIGHT HOURS. RAINFALL RATES IN EXCESS OF ONE INCH PER HOUR...WITH STORMS REPEATEDLY MOVING OVER THE SAME AREA WILL LIKELY LEAD TO WIDESPREAD RAINFALL AMOUNTS IN THE 1 TO 2 INCH RANGE...WITH SOME AREAS RECEIVING UP TO OR IN EXCESS OF 3 INCHES. MUCH OF THIS RAIN WILL FALL OVER AREAS THAT RECEIVED HEAVY RAIN THIS PAST WEEKEND...AND ON TOP OF NEARLY SATURATED GROUND. AS A RESULT...A FLASH FLOOD WATCH REMAINS IN EFFECT FOR A LARGE PORTION OF THE OUTLOOK AREA THROUGH TUESDAY MORNING. IN ADDITION...EXTENSIVE RIVER FLOODING CAN BE EXPECTED FOR THE NEXT SEVERAL DAYS DUE TO THE RUNOFF FROM THIS EXCESSIVE RAINFALL. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY THUNDERSTORMS FROM OVERNIGHT WILL EXIT THE OUTLOOK AREA TUESDAY MORNING...AS A COLD FRONT PUSHES INTO NORTHWEST MISSOURI. ADDITIONAL THUNDERSTORM DEVELOPMENT AND POSSIBLE SEVERE WEATHER MAY OCCUR ALONG AND AHEAD OF THIS STRONG COLD FRONT TUESDAY AFTERNOON ACROSS THE FAR EASTERN PARTS OF THE OUTLOOK AREA. ANY THUNDERSTORMS THAT HAPPEN TO DEVELOP IN THE OUTLOOK AREA WILL QUICKLY MOVE SOUTH AND EAST BY LATE TUESDAY AFTERNOON. BEHIND THIS STRONG COLD FRONT TUESDAY AFTERNOON...GUSTY NORTHWEST WINDS WILL SURGE INTO NORTHERN MISSOURI.
