NWS STORM PREDICTION CENTER NORMAN OK
0536 PM CDT SAT JUN 16 2012
AREAS AFFECTED...PARTS OF E CNTRL AND SE KS...MUCH OF SWRN THRU
CNTRL/E CNTRL MO
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 162236Z - 170000Z
PROBABILITY OF WATCH ISSUANCE...40 PERCENT
SUMMARY...SOME UNCERTAINTY LINGERS...BUT CONVECTIVE TRENDS ARE BEING
MONITORED FOR THE POSSIBILITY OF AN INCREASING SEVERE THREAT THAT
COULD REQUIRE AN ADDITIONAL WW THIS EVENING SOUTH OF WWS 400 AND
401.
DISCUSSION...IN THE WAKE OF THE CONVECTIVELY GENERATED CYCLONIC
VORTICITY CENTER MIGRATING EASTWARD INTO SOUTHEAST
IOWA...NEW...DEEPENING CONVECTIVE DEVELOPMENT PERSISTS SOUTHWEST
THROUGH SOUTH AND EAST OF THE KANSAS CITY METRO AREA IN RESPONSE TO
LOWER/MID TROPOSPHERIC WARM ADVECTION. INHIBITION ASSOCIATED WITH
EASTWARD ADVECTING ELEVATED MIXED LAYER AIR MAY STILL BE SUPPRESSING
CONVECTION...BUT WITH A GRADUAL VEERING OF MID-LEVEL WINDS FROM
WESTERLY TO NORTHWESTERLY INTO THE EVENING HOURS...THIS MAY WEAKEN
WITH MID-LEVEL COOLING. COINCIDING WITH MODEST SOUTHWESTERLY INFLOW
OF MOIST AIR /CHARACTERIZED BY MID 60S TO NEAR 70F SURFACE DEW
POINTS ACROSS OKLAHOMA INTO SOUTHEAST KANSAS/...INCREASING
INSTABILITY AND VERTICAL SHEAR MAY CONTRIBUTE TO THE EVOLUTION OF AN
ADDITIONAL ORGANIZED STORM CLUSTER. THIS SEEMS MOST LIKELY ACROSS
THE MISSOURI OZARKS REGION BY 00-03Z...WITH A TENDENCY TO PROPAGATE
SOUTHEASTWARD NEAR AND SOUTH OF THE LOWER MISSOURI RIVER VICINITY.
