AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
618 AM CDT TUE JUN 1 2010

...UPDATED AVIATION DISCUSSION...

.DISCUSSION...

SEVERAL CONCERNS THIS FORECAST...CENTERING AROUND PRECIPITATION
CHANCES AS MID LEVEL FLOW HAS BECOME MORE ZONAL WITH WEAKER SHORT
WAVES.

EVEN FOR THE SHORT TERM...TODAY AND TONIGHT...MUCH UNCERTAINTY
REMAINS ON HOW CONVECTION MAY PLAY OUT. FOR THIS MORNING...A WEAK H7
WAVE COMING OUT OF WESTERN KANSAS...IS EXPECTED TO SUPPORT
CONVECTION MOVING INTO EASTERN KANSAS BY LATE MORNING. NAM 310K
ISENTROPIC SURFACE SHOWING TIGHTENING GRADIENT INTO EASTERN KANSAS
BY 18Z WITH CONVECTION DEVELOPING IN EASTERN KANSAS AND WESTERN
MISSOURI BY MID AFTERNOON.

BY THIS EVENING ANOTHER H7 WAVE DEVELOPS IN WESTERN KANSAS IN
RESPONSE TO A SLIGHTLY STRONGER H5 WAVE MOVING THROUGH THE CENTRAL
ROCKIES. A SURFACE FRONT IS EXPECTED TO BE SETTING UP FROM NORTHEAST
KANSAS ACROSS NORTHWEST MISSOURI AND INTO SOUTHERN IOWA BY THIS
TIME. THIS BOUNDARY IS EXPECTED TO BE THE FOCUS FOR CONVECTION
TONIGHT AS THIS H7 WAVE MOVES EAST WITH AN INCREASING LOW LEVEL JET
IN ADVANCE OF IT. THERE WILL BE THE POTENTIAL OF HEAVY RAINFALL IN
EXTREME NORTHERN MISSOURI WITH THIS SET UP. POTENTIAL WILL EXIST FOR
FLOODING PROBLEMS IF THIS BOUNDARY SETS UP IN THE REGION WITH AN MCS
DEVELOPING ALONG IT...SO A FLOOD WATCH MAY NEED TO BE ISSUED TODAY.

MID LEVEL H7 AND H5 WAVES WILL BE MOVING ACROSS NORTHERN MISSOURI
DURING THE DAY ON WEDNESDAY...WITH THE SURFACE FRONT EXPECTED TO BE
DRIVEN SOUTHWARD WITH THE COLD POOL FROM THE OVERNIGHT CONVECTION.
THIS WILL LIKELY SEND THE FRONT SOUTH AND EAST OF THE FORECAST AREA
BY 00Z THURSDAY...BUT STILL POST FRONTAL CONVECTION WILL BE POSSIBLE
UNTIL THE MID LEVEL TROUGH PASSAGE WEDNESDAY EVENING.

ON THURSDAY...WILL DRY THINGS OUT AS IT APPEARS THE FORECAST AREA
WILL BE IN BETWEEN WAVES...BUT WITH SUCH A FLOW...TIMING OF THESE
WEAK FEATURES IS PROBLEMATIC...AND MODELS REFLECT THIS WITH A
VARIETY OF SOLUTIONS. THERE SEEMS TO BE SOME CONSENSUS THAT ANOTHER
MORE NORTHERLY WAVE WILL BE MOVING INTO THE NORTHERN HIGH PLAINS BY
THURSDAY EVENING...WITH WARM AIR ADVECTION AHEAD OF THIS FEATURE
SETTING OFF CONVECTION THAT COULD CLIP NORTHWEST AREAS BY THURSDAY
EVENING. THEN THIS WAVE MAY BRING THE NEXT ROUND OF CONVECTION WITH
A SURFACE FRONT MOVING THROUGH THE AREA ON FRIDAY. PREVIOUS FORECAST
HAD THE BETTER CHANCES OF THIS CONVECTION FRIDAY NIGHT...AND HAVE
SOME CONCERNS THIS FASTER TIMING MAY PREVAIL.  BUT FOR NOW WILL NOT
MAKE ANY BIG CHANCES TO THE FURTHER OUT PERIODS AS CONFIDENCE
RAPIDLY DIMINISHES WITH THE MODELS STARTING TO REALLY DIVERGE ON
THEIR SOLUTIONS HEADING INTO THE WEEKEND.

.AVIATION...

LOW CONFIDENCE FORECAST WITH UNCERTAINTY REGARDING CONVECTIVE
EVOLUTION OF ONGOING SHOWERS/THUNDERSTORM ACTIVITY CURRENTLY ACROSS
WESTERN/CENTRAL KANSAS. THIS ACTIVITY IS OCCURRING WITHIN WAA REGIME
AS 35-40 KT LLJ HAS RESULTED IN MODEST ISENTROPIC ASCENT ACROSS THIS
AREA. CONVECTION WILL CONTINUE TO PROPAGATE EASTWARD WITH TIME AND
EXPECT THE BULK OF THIS ATIVITY TO REMAIN ACROSS PORTIONS OF NORTHERN
KANSAS AND NEBRASKA ON THE NOSE OF LLJ. HOWEVER...AS EASTERN EXTENT
OF LLJ VEERS LATER THIS MORNING...ADDITIONAL CONVECTION MAY DEVELOP
WITHIN WEAK TO MODERATE ISENTROPIC ASCENT ACROSS CENTRAL/EASTERN
KANSAS...WHICH MAY BE TRYING TO OCCUR ATTM AND IS FURTHER SUPPORTED
BY HIGH RESOLUTION SHORT RANGE MODEL OUTPUT. OTHERWISE...ONGOING
CONVECTION...SHOULD IT SURVIVE ACROSS KANSAS...WOULD NOT REACH THE
AREA UNTIL LATER THIS AFTERNOON. WILL NOT MENTION PRECIP IN THE TAF
AT THIS TIME UNTIL A BETTER HANDLE ON THE EVOLUTION ON ONGOING AND
POTENTIALLY NEW CONVECTION IS REALIZED.

100 PM CDT TUE JUN 1 2010

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

.DAY ONE...THIS AFTERNOON AND TONIGHT

 ISOLATED...BUT POTENTIALLY SEVERE THUNDERSTORMS...WILL BE POSSIBLE
 ACROSS THE OUTLOOK AREA THIS AFTERNOON. A FEW THUNDERSTORMS WERE
 ONGOING ACROSS THE KANSAS CITY METRO EARLY THIS AFTERNOON...AND
 WILL MOVE EAST INTO AN INCREASINGLY MOIST AND UNSTABLE AIRMASS.
 THE PRIMARY THREAT WITH THESE STORMS WILL BE LARGE HAIL...BUT
 INCREASING VERTICAL WIND SHEAR THROUGH THE AFTERNOON MAY ALSO
 PROMOTE AN INCREASING THREAT FOR DAMAGING WINDS AS THESE STORMS
 MOVE TOWARD CENTRAL MISSOURI.

 OTHERWISE...A HOT AND INCREASINGLY HUMID AIRMASS WILL BUILD ACROSS
 THE REMAINDER OF THE OUTLOOK AREA THIS AFTERNOON IN ADVANCE OF A
 COLD FRONT STRETCHING THROUGH NEBRASKA AND IOWA. SEVERE
 THUNDERSTORMS...INCLUDING SUPERCELLS...ARE EXPECTED TO DEVELOP
 ALONG AND AHEAD OF THIS COLD FRONT...BUILDING INTO FAR NORTHWEST
 MISSOURI AND EXTREME NORTHEAST KANSAS AFTER 9 PM. A FEW OF THESE
 STORMS MAY BE QUITE SEVERE...CAPABLE OF PRODUCING LARGE DESTRUCTIVE
 HAIL...DAMAGING WINDS AND ISOLATED TORNADOES. THE HIGHEST THREAT
 AREA FOR SEVERE WEATHER THIS EVENING INTO THE OVERNIGHT HOURS WILL
 BE ALONG AND NORTHWEST OF A ST. JOSEPH TO TRENTON TO UNIONVILLE
 LINE.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

 THE THREAT OF SEVERE WEATHER SHOULD SHIFT EAST OF THE REGION EARLY
 WEDNESDAY MORNING...BUT AN OUTFLOW BOUNDARY LEFT IN THE WAKE OF
 EARLIER THUNDERSTORMS WILL SERVE AS THE FOCUS FOR REDEVELOPMENT IN
 THE AFTERNOON. THUNDERSTORMS SHOULD DEVELOP AND BECOME QUITE
 WIDESPREAD ACROSS CENTRAL AND WEST CENTRAL MISSOURI WEDNESDAY
 AFTERNOON. SEVERE WEATHER MAY AGAIN OCCUR WITH THE MAIN THREATS
 BEING DAMAGING WINDS AND LARGE HAIL.

 LOOKING FURTHER AHEAD...THUNDERSTORMS CHANCES WILL INCREASE INTO
 WEEKEND AS A WARM AND HUMID AIR MASS INTERACTS WITH SEVERAL UPPER
 AIR DISTURBANCES. IT REMAINS TOO EARLY TO DETERMINE IF THIS
 ACTIVITY WILL BE SEVERE.

.SPOTTER INFORMATION STATEMENT...

 SPOTTER ACTIVATION MAY BE NEEDED EAST OF THE KANSAS CITY AREA
 THIS AFTERNOON...AND WILL LIKELY BE REQUIRED ACROSS NORTHEAST
 KANSAS AND FAR NORTHERN MISSOURI INTO THE MID AND LATE EVENING
 HOURS.
