AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
633 PM CDT SAT MAR 19 2011

...UPDATED AVIATION DISCUSSION...

.DISCUSSION...
/435 PM CDT SAT MAR 19 2011/
SHORT RANGE (TODAY THROUGH MONDAY)...

ONGOING STORMS ACROSS THE FORECAST REGION ARE THE FOCUS OF THE
WEATHER IN THE SHORT TERM...BUT THERE IS ANOTHER SIGNIFICANT
CHANCES AT SEVERE WEATHER STARTING IN THE MEDIUM RANGE...ON
TUESDAY.

MORNING STORMS ACROSS NORTH CENTRAL OKLAHOMA RECEIVED SOME
ASSISTANCE FROM A BROKEN JET STREAK AT H3...WHICH PROVIDED A NICE
DIFFLUENT FLOW ALOFT ACROSS SOUTHEAST KANSAS AND FAR SOUTHWEST
MISSOURI UNDER THE STRONGER WESTERLIES TOPPING THE UPPER LEVEL RIDGE.
COMBINE THIS DIFFLUENT FLOW WITH MUCAPE VALUES EARLIER TODAY OF 500
TO 1000 J/KG IN THOSE AREAS...AND SEVERE THUNDERSTORMS RESULTED.
EARLY THIS AFTERNOON ACTIVITY HAS CONTINUED TO SPREAD NORTH AND EAST
INTO THE WESTERN HALF OF MISSOURI...AND WHILE SOME OF THE ELEVATED
INSTABILITY ADVECTED IN ALOFT ACROSS THE KANSAS-MISSOURI BORDER...IN
GENERAL THE SHEAR AND INSTABILITY BOTH HAVE BEEN INSUFFICIENT TO
SUPPORT MAINTAINING ANY SEVERE STORMS. AND...WITH THE DEVELOPMENT OF
THE LINEAR LINE OF STORMS ACROSS SOUTHWEST MISSOURI...THOUGHTS ARE
THAT OUR SEVERE POTENTIAL FOR THE REST OF THE AFTERNOON AND EVENING
HOURS IS DONE.

LOOKING TO LATE THIS EVENING THROUGH EARLY SUNDAY MORNING TIME
FRAME...NOCTURNAL JET WILL GET CRANKING LATER TONIGHT...FOCUSING THE
JUICIER THETA-E ADVECTION ACROSS NORTHERN KANSAS AND NORTHERN
MISSOURI LATE TONIGHT AS A WEAK SHORTWAVE EXITS THE CENTRAL ROCKIES
AND MOVES TOWARDS THE NORTHERN PLAINS. THIS IS EXPECTED TO ALLOW ONE
OF TWO SCENARIOS TO PLAY OUT FOR TONIGHT. ONE...THE ACTIVITY
CURRENTLY IN SOUTH CENTRAL KANSAS HOLDS TOGETHER UNTIL IT ADVECTS
INTO THE NORTHERN HALF OF OUR FORECAST AREA LATER THIS EVENING...NOT
LOOKING LIKELY AT THIS TIME. TWO...REDEVELOPMENT OF STORMS OCCURS IN
PLACE ACROSS NORTHERN MISSOURI EARLY SUNDAY MORNING...THOUGH WITH
THIS SECOND SCENARIO THE DEVELOPMENT MIGHT BE JUST FAR ENOUGH NORTH
TO NOT THREATEN OUR FORECAST AREA. HAVE LEFT LIKELY TO CATEGORICAL
POPS IN FOR THE OVERNIGHT HOURS TO COVER EITHER OF
POSSIBILITY...THOUGH THE EVENING SHIFT MIGHT BE ABLE TO REFINE
PLACEMENT OF HIGHER POPS AS THE ACTIVITY IN SOUTH CENTRAL KANSAS
EVOLVES.

SUNDAY INTO MONDAY...THE WARM FRONT THAT WAS ALONG THE RED RIVER
VALLEY WELL TO OUR SOUTH THIS MORNING...IS EXPECTED TO LIFT UP
THROUGH MUCH OF THE FORECAST AREA SUNDAY MORNING...STALLING OUT NEAR
THE IOWA BORDER THROUGH MONDAY AS THE CENTRAL ROCKIES SHORTWAVE
MOVES INTO THE UPPER GREAT LAKES. ANY ONGOING ACTIVITY FROM THE
EARLY MORNING HOURS OF SUNDAY COULD STILL BE WORKING TO EXIT THE
FORECAST AREA THROUGH NOON...BUT THOUGHTS ARE THAT WE MIGHT STRUGGLE
FOR ACTIVITY IN THE AFTERNOON THANKS TO AN ELEVATED MIXED
LAYER...AND/OR SUBSIDENCE IN THE WAKE OF ANY EXITING ACTIVITY.
SO...HAVE LEFT SLIGHT CHANCE TO CHANCE POPS IN FOR SUNDAY AFTERNOON
NEAR THE IOWA BORDER...WITH CHANCE POPS MONDAY ACROSS THE NORTHERN
THIRD OF THE FORECAST AREA ROUGHLY ASSOCIATED WITH THE EXPECTED
STALLED FRONTAL BOUNDARY.

CUTTER

MEDIUM RANGE (TUESDAY THROUGH SATURDAY)...

AN ENERGETIC TROUGH WILL EJECT INTO THE PLAINS STATES TUESDAY AND
WITH SOUTHERLY SURFACE WINDS PUMPING MOISTURE INTO THE REGION FOR
SEVERAL DAYS AHEAD OF THE SYSTEM THE THREAT OF SEVERE WEATHER
IS INCREASING. BY THE EVENING HOURS THE LEFT FRONT
QUADRANT OF THE UPPER JET WILL BE NOSING INTO THE LOWER MISSOURI
VALLEY WITH STRONGLY DIFFLUENT FLOW. THIS STRONGLY DIFFLUENT FLOW
WILL RESIDE OVER TOP OF A WELL PRONOUNCED WARM SECTOR. STRONG LOW TO
MID LEVEL WINDS WILL LEAD TO SHEAR VALUES SUPPORTIVE FOR SEVERE
STORMS. HODOGRAPHS SHOW DECENT LOW LEVEL CURVATURE SO DESPITE SOUTH
SOUTHWESTERLY SURFACE FLOW ALL CONVECTIVE MODES AND ASSOCIATED
SEVERE TYPES SEEM REASONABLE AT THIS POINT. THE ONE CONCERN
CONTINUES TO BE WHETHER OR NOT CLOUDS WILL ERODE ENOUGH IN THE LARGE
AND WELL PRONOUNCED WARM SECTOR TO ALLOW FOR MORE WIDESPREAD AND
INCREASED INSTABILITY. THIS UNCERTAINTY LOWERS CONFIDENCE LEVELS ON
JUST HOW WIDESPREAD A SEVERE EPISODE IT MAY BE...DESPITE THE MANY
POSITIVES THIS SYSTEM IS DEPICTING FOR A DAY FOUR FORECAST.

THE COLD FRONT ASSOCIATED WITH THE TUESDAY SYSTEM WILL MOVE THROUGH
THE FORECAST AREA TUESDAY NIGHT AND BEHIND IT COLDER AIR WILL
DOMINATE THE REGION THROUGH THE END OF THE WEEK. THIS SHOULD ALSO
LEAD TO DRIER WEATHER THROUGH THE END OF THE WEEK WITH ONE
EXCEPTION. MODELS ARE INDICATING A SYSTEM TRACKING THROUGH THE
SOUTHERN PLAINS WHICH MAY BRING A CHANCE FOR RAIN AND SNOW THURSDAY
INTO FRIDAY.

.AVIATION...

FOR THE 00Z TAFS...SECOND REGION OF ELEVATED CONVECTION FROM CENTRAL
TO EAST CENTRAL KS WILL LIFT ENE AND AFFECT THE TERMINALS THROUGH
THIS EVENING. SOME SCATTERED SHOWERS WHICH POPPED UP OVER WEST
CENTRAL MO WILL AFFECT KMKC MORE SO THAN KMCI. BRISK SELY SURFACE
WINDS WILL REMAIN GUSTY THIS EVENING. VFR CEILINGS SHOULD SHORTLY
GIVE WAY TO MVFR CEILINGS AS THIS NEXT CLUSTER OF SHOWERS/EMBEDDED
THUNDERSTORMS APPROACHES. IN THE WAKE OF THIS NEXT REGION OF RAIN
EXPECT MVFR FOG AND CEILINGS. OVERALL LATEST RUC IS HANDLING THE
ONGOING CONVECTION BEST. NAM/GFS/HRRR HAVE NOT DONE SUCH A STELLAR
JOB. WILL MODEL RAIN CHANCES LATER TONIGHT ON WHERE ISENTROPIC
ASCENT SHOULD BE STRONGEST WITH VEERING OF LOW LEVEL JET. THIS
POINTS MORE INTO NW MO AND AFFECTING THE KSTJ TERMINAL TOWARDS THE
PRE-DAWN HOURS. CONFIDENCE LOW IN THE SOUTHERN EDGE OF ANY
CONVECTION REACHING KMCI/KMKC SO WILL LEAVE RAIN CHANCES OUT FOR NOW
AFTER 05Z.

PASSAGE OF A NEBULOUS WARM FRONT SUNDAY MORNING SHOULD ALLOW SURFACE
WINDS TO BACK TO THE SOUTH AND RATCHET UP. ALSO EXPECTING MVFR
STRATOCU DECK TO SCOUR OUT WITH BETTER AFTERNOON MIXING.

710 PM CDT SAT MAR 19 2011

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

.DAY ONE...TONIGHT

A SECOND ROUND OF SHOWERS AND EMBEDDED THUNDERSTORMS WILL AFFECT EAST
CENTRAL KANSAS AND WEST CENTRAL KANSAS THIS EVENING AND SPREAD INTO
NORTHERN MISSOURI LATER TONIGHT.

ADDITIONAL SHOWERS AND ISOLATED THUNDERSTORMS ARE EXPECTED TO
DEVELOP ACROSS CENTRAL AND NORTHERN KANSAS LATER TONIGHT...AFFECTING
NORTHEAST KANSAS AND NORTHWEST MISSOURI AFTER MIDNIGHT. NO SEVERE
THUNDERSTORMS ARE EXPECTED OVERNIGHT. HOWEVER...SMALL HAIL WITH SOME
OF THE STRONGER STORMS WOULD BE POSSIBLE.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

EMBEDDED THUNDERSTORMS MAY STILL BE LINGERING ACROSS NORTHERN
MISSOURI SUNDAY MORNING. HOWEVER...THE THUNDERSTORM THREAT WILL EXIT
NORTHERN MISSOURI LATER SUNDAY MORNING AS A WARMER AND MORE STABLE
LAYER ALOFT SPREADS ACROSS THE OUTLOOK AREA AND INHIBITS THE
DEVELOPMENT OF THUNDERSTORMS.

OTHERWISE...A VERY ENERGETIC STORM SYSTEM WILL ENTER THE PLAINS
TUESDAY...WITH THUNDERSTORM CHANCES INCREASING ALONG A FRONT
APPROACHING FROM THE WEST ON TUESDAY AFTERNOON AND EVENING. SEVERE
WEATHER MAY BE POSSIBLE WITH THESE STORMS...PARTICULARLY ACROSS
EASTERN KANSAS AND FAR WESTERN MISSOURI.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT EXPECTED THROUGH MONDAY NIGHT. SPOTTER
ACTIVATION MAY BE NEEDED TUESDAY AFTERNOON AND EVENING ACROSS PARTS
OF THE OUTLOOK AREA.
