AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
730 PM CDT SUN JUN 20 2010

...MESOSCALE UPDATE...

.DISCUSSION...

WELL DEFINED OUTFLOW BOUNDARY CURRENTLY ALIGNED FROM NEAR KIXD-KCNK
HAS BECOME THE FOCUS FOR SLIGHTLY DEEPER CONVECTIVE
INITIATION...TAPPING A RESERVOIR OF MLCAPES ON THE ORDER OF
3000-4000 J/KG ACROSS CNTRL/SRN KANSAS. THIS BOUNDARY HAS ALSO
BECOME THE TIGHT DIFFERENTIATING LINE BETWEEN STRONG CAPPING TO THE
SW (+14C TO +15C AT H7) AND NEGLIGIBLE CAPPING (AROUND +9C AT H7)
OVER SERN NEBRASKA (WHERE DEEP SATURATION CONTINUES TO SUPPORT
SOMEWHAT ELEVATED STORMS). 00Z KTOP SOUNDING INDICATES TREMENDOUS
LOW LEVEL MIXING RATIOS ALONG THE AFOREMENTIONED BOUNDARY...SUCH
THAT ONLY MINIMAL INHIBITION EXISTS JUST ABOVE THE H7 LAYER. BASED
ON SATELLITE PRESENTATION OF CLOUD STRUCTURE AND RADAR
TRENDS...THINKING SOME MEASURE OF SUBSIDENCE STILL REMAINS TO
PRECLUDE MORE EXPLOSIVE DEVELOPMENT IN THE VERY SHORT TERM.
HOWEVER...AS LLJ BEGINS TO STRENGTHEN IN THE NEXT HOUR OR TWO...WILL
NEED TO CLOSELY WATCH EAST CENTRAL KANSAS FOR MORE ROBUST
DEVELOPMENT AS DEEP LAYER ASCENT INCREASES.

OTHERWISE...RAPIDLY ORGANIZING MCS OVER NORTH CNTRL KANSAS WAS
QUICKLY OBTAINING AN EASTWARD TRAJECTORY WITH H9-H8 LAYER WINDS
VEERING SLIGHTLY AND NOTABLY INCREASING IN THE PAST HOUR. EXPECTING
CONTINUED UPSCALE GROWTH OF A SMALL BOW/QLCS STRUCTURE DURING THE
EVENING HOURS RIDING ALONG THE NRN PERIPHERY OF THE STRONGER EML
(SEE MOST RECENT SPC MCD). TIMING THIS MESOSCALE SYSTEM EASTWARD IS
QUITE DIFFICULT OWING TO THE EXPECTED SURGE AND INCREASED FORWARD
PROPAGATING SPEED...BUT BACK OF THE ENVELOPE CALCULATIONS BRING THIS
SYSTEM INTO FAR EASTERN KANSAS/NWRN MISSOURI AS SOON THE
930PM-1000PM TIME FRAME...BUT MORE LIKELY TOWARDS 1030PM-1100PM.

PER RUC ANALYSIS AND 00Z SOUNDING DATA...NOSE OF STEEPER MIDLEVEL
LAPSE RATES EDGES EAST THROUGH THE WRN CWA (HIGHER THAN PREVIOUSLY
EXPERIENCED IN THE PAST SEVERAL EVENTS)...SO THE PROSPECT FOR A FEW
LARGE HAIL STONES CERTAINLY EXISTS...PARTICULARLY IN ANY DISTINCT
THUNDERSTORMS CELLS ALONG THE OLD BOUNDARY AND AHEAD OF THE MAIN
CONVECTIVE COMPLEX. HOWEVER...BY FAR DAMAGING WINDS WILL BE THE
MAIN THREAT THROUGH THE EVENING AND EARLY OVERNIGHT HOURS. BIGGEST
WILD CARD IS THE POSSIBILITY OF THE CELLS PERCOLATING OVER FAR ERN
KANSAS FORMING INTO A QUASI-WARM ADVECTION WING FEEDING INTO THE
MAIN COMPLEX...AND POSSIBILITY PROVIDING ENOUGH OF A LOW LEVEL
VORTICITY SOURCE FOR A BRIEF SPIN-UP IN THE MORE CLASSIC QLCS
CONCEPT. NOT TO MENTION THE TENDENCY FOR DEEP CONVECTION TO ATTEMPT
TO TRAIN ALONG THIS OLD BOUNDARY...BRINGING AN ENHANCED THREAT FOR
EXCESSIVE RAINFALL. SOUTHERN SEVERE AND HEAVY RAINFALL THREAT MAY BE
LIMITED BY THE ORIENTATION OF THE LLJ AND EML...WHICH CURRENTLY
LOOKS TO ALIGN NEAR HIGHWAY 50...WHILE THE NORTHEAST EXTENT TO
SEVERE MAY BE DETERMINED BY MORE LIMITED INSTABILITY ALONG THE
MISSOURI/IOWA BORDER.

.PREVIOUS DISCUSSION...

/354 PM CDT SUN JUN 20 2010/
THUNDERSTORM ACTIVITY CONTINUES TO DEVELOP IN SOUTHEAST NEBRASKA
THIS AFTERNOON...ONLY TO SLIDE EAST SOUTHEAST INTO MISSOURI AND DIE
OFF. STORMS MOVING INTO NORTHEAST KANSAS AND NORTHWEST MISSOURI HAVE
HAD A DIFFICULT TIME LASTING VERY LONG AS THE ENVIRONMENT IS A BIT
MORE WORKED OVER FROM MORNING ACTIVITY. ALSO...WHILE MUCH OF KANSAS
AND MISSOURI HAS MORE THAN ADEQUATE INSTABILITY FOR THUNDERSTORMS...
AS ILLUSTRATED BY THE MLCAPES AT OR ABOVE 1000 J/KG OUTSIDE EXTREME
NORTHWEST MO...SHEAR QUICKLY DROPS OFF AS THE UPPER LEVEL FLOW IS
FOCUSED A LITTLE FARTHER NORTH OVER THE TOP OF THE FLATTENED RIDGE
THAT HAS BEEN RESIDING ACROSS THE CENTRAL PLAINS IN RECENT DAYS.
ACTIVITY IN NEBRASKA CONTINUES TO PERCOLATE AS H8 WINDS REMAIN FROM
DUE SOUTH...AND INTERSECT WHAT IS PROBABLY THE TRUE LOCATION OF THE
WARM FRONT IN SOUTHEAST NEBRASKA. VISIBLE SATELLITE IMAGERY AND WIND
FIELDS SHOW A BOUNDARY MUCH FARTHER SOUTH...BUT THIS IS SIMPLY THE
OUTFLOW FROM THIS MORNINGS ACTIVITY.

MAIN ISSUES FOR TONIGHT...AS IT HAS BEEN EVERY NIGHT IN RECENT
DAYS...IS WHERE THE THUNDERSTORM ACTIVITY WILL INITIATE THIS
AFTERNOON/TONIGHT...AND WHERE IT WILL GO ONCE IT STARTS MOVING EAST.
CURRENTLY INITIATION IS ONGOING ACROSS SOUTHEAST NEBRASKA AND
SOUTHWEST KANSAS. ACTIVITY IN WEST KANSAS IS WHAT WILL MOST LIKELY
IMPACT OUR AREA OVERNIGHT THROUGH MONDAY MORNING. FOCUS FOR THE WEST
KANSAS STORMS SHOULD MOVE INTO NORTH CENTRAL KANSAS AS THE LOW LEVEL
JET FOCUSES TONIGHT ACROSS THE BOUNDARY IN THAT REGION. THAT WOULD
PLACE ANY EASTWARD MOVING MCS ALONG AND NORTH OF INTERSTATE 70.
HOWEVER...18Z SOUNDINGS FROM TOPEKA DO INDICATE A GROWING CAP AS H7
TEMPS WENT FROM 12 TO 13 CENTIGRADE IN THE 6 HOURS BETWEEN
OBSERVATIONS. HAVE KEPT THE HIGHEST POPS...LIKELIES...ALONG THE IOWA
BORDER AS A RESULT...BUT DO HAVE AT LEAST CHANCE POPS AS FAR SOUTH AS
INTERSTATE 70. EVENING SHIFT MAY HAVE TO ADJUST BASED ON ACTIVITY TO
THE WEST LATER TONIGHT.

HAVE CONTINUED THE TREND OF KEEPING HIGHEST POPS LOCATED ALONG THE
IOWA BORDER REGION...THROUGH AT LEAST TUESDAY...AS THIS PERSISTS IN
LOOKING LIKE THE MAIN CORRIDOR FOR ACTIVITY GIVEN THE PLACEMENT OF
THE STALLED FRONT THERE. COME WEDNESDAY A SHORTWAVE IS EXPECTED TO
MOVE INTO THE GREAT LAKES...AND MIGHT BE ABLE TO PUSH THE FRONTAL
BOUNDARY FARTHER SOUTH...RESULTING IN POTENTIAL FOR RAIN BACK ACROSS
CENTRAL MISSOURI. AFTER THIS NORTHERN STREAM SHORTWAVE MOVES BY...WE
ARE LOOKING FOR THE RIDGE AXIS TO POP BACK UP A LITTLE FARTHER TO THE
WEST...WHICH SHOULD RESULT IN MULTIPLE DAYS OF FORECAST DRY WEATHER.
SOMETHING WE HAVE NOT SEEN ACROSS THE ENTIRE FORECAST AREA FOR A
LITTLE WHILE.

OTHERWISE...FOCUSING BACK ON THE IMMEDIATE NEXT COUPLE OF
DAYS...TEMPERATURES AND HUMIDITY'S WILL NEED CLOSE WATCHING. EACH
MORNINGS MCS ACTIVITY HAS BROUGHT SOME RELIEF TO THE HOT AND HUMID
CONDITIONS /ESPECIALLY ACROSS AREAS FROM NORTHEAST KANSAS THROUGH
NORTHEAST MISSOURI/...BUT IF ANY OVERNIGHT ACTIVITY FAILS TO SEND AN
OUTFLOW BOUNDARY SOUTH ACROSS THE REGION AREAS AROUND AND SOUTH OF
THE MISSOURI RIVER WILL EXPERIENCE HEAT INDEX VALUES IN THE 100+
RANGE. THIS WILL NEED CAREFUL WATCHING AS HEAT ADVISORIES MAY BE
NEEDED.

CUTTER

&&

.AVIATION...

FOR THE 00Z TAFS...MUCH UNCERTAINTY ON WHEN ANY CONVECTION COULD BE
AT THE TERMINALS. WATCHING CONGESTED AREA OF CU TO THE WEST OF THE
TERMINALS AT THIS TIME THAT HAS POTENTIAL...ALTHOUGH ANVIL BLOW OFF
FROM WESTERN KANSAS STORMS MAY START TO INTERFERE WITH THIS AREA
AFTER A WHILE. ALSO CONCERN ABOUT WESTERN KANSAS STORMS STARTING TO
ORGANIZE AND MARCH EAST THIS EVENING AS THE H85 JET VEERS. THINKING
THIS ACTIVITY WOULD WANT TO TRACK ALONG THE BOUNDARY SITTING JUST
SOUTH OF THE KANSAS CITY AREA. SO WE COULD SEE CONVECTION ROLLING
INTO THE TERMINALS IN THE LATE EVENING TO EARLY MORNING HOURS.

WITH SO MUCH UNCERTAINTY...WILL JUST PLACE A CB GROUP IN FOR NOW AND
AMEND AS CONVECTION TIMING BECOMES CLEARER.

648 PM CDT SUN JUN 20 2010

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHWEST...NORTH CENTRAL AND
WEST CENTRAL MISSOURI...AS WELL AS EXTREME EASTERN KANSAS.

.DAY ONE...TONIGHT

STRONG TO SEVERE THUNDERSTORMS WILL BE POSSIBLE TONIGHT. INITIALLY
SCATTERED STORMS WILL BE POSSIBLE EARLY THIS EVENING...MAINLY IN
AREAS FROM KANSAS CITY...NORTHWARD TO THE IOWA BORDER. SOME OF THESE
STORMS MAY PRODUCE LARGE HAIL AND STRONG WINDS. LOCALIZED HEAVY
RAINFALL FROM THE SLOW MOVEMENT OF THE STORMS...MAY ALSO CAUSE SOME
MINOR FLOODING PROBLEMS.

THEN BY LATE EVENING...A MORE ORGANIZED AREA OF STORMS MAY BE MOVING
EAST ACROSS KANSAS AND HEADING TOWARD NORTHEAST KANSAS AND WEST
CENTRAL AND NORTHWEST MISSOURI...MAINLY FROM THE PAOLA AND
HARRISONVILLE AREAS...NORTHWARD. THESE STORMS WOULD HAVE THE POTENTIAL TO
CONTINUE INTO CENTRAL AND NORTH CENTRAL MISSOURI OVERNIGHT. THIS TYPE
OF STORM COMPLEX WOULD HAVE THE ABILITY TO CAUSE MORE WIDESPREAD WIND
DAMAGE...LARGE HAIL...AND LOCALIZED FLOODING FROM HIGH RAINFALL RATES.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

THIS ACTIVE PATTERN OF MAINLY NIGHTTIME AND EARLY MORNING
THUNDERSTORM COMPLEXES...WITH POSSIBLE SCATTERED CONVECTION IN THE
LATE AFTERNOON AND EARLY EVENING PERIODS WILL CONTINUE THROUGH THE
WEEK. THUS THE THREAT OF SEVERE WEATHER AS WELL AS VERY HEAVY
RAINFALL WHICH COULD RESULT IN ADDITIONAL FLOODING OR AGGRAVATE THE
FLOODING PROBLEMS ALREADY OCCURRING WILL PERSIST.  CONFIDENCE
REMAINS LOW ON TIMING AND EXACT LOCATION OF THESE STORM SYSTEMS DUE
TO THE MANY OUT FLOW BOUNDARIES PREVIOUS SYSTEMS HAVE LEFT BEHIND.

IN ADDITION TO THE THUNDERSTORM THREAT...VERY WARM AND HUMID
CONDITIONS WILL CONTINUE THIS WEEK...ALTHOUGH THUNDERSTORM ACTIVITY
MAY PROVIDE SOME PERIODS OF RELIEF. TEMPERATURES IN THE 90S COMBINED WITH
HIGH RELATIVE HUMIDITY WILL PRODUCE HEAT INDICES AROUND OR ABOVE 100
DEGREES AT TIMES.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED TONIGHT. ON MONDAY AND TUESDAY...THE
MORE LIKELY AREA THAT SPOTTER ACTIVATION MAY BE NEEDED WOULD BE
ACROSS NORTHERN MISSOURI AND NORTHEAST KANSAS.
