   MESOSCALE DISCUSSION 0450
   NWS STORM PREDICTION CENTER NORMAN OK
   0437 AM CDT TUE APR 26 2016

   AREAS AFFECTED...NORTHEAST KS...FAR SOUTHEAST
   NEB...NORTHWEST/WEST-CENTRAL MO

   CONCERNING...SEVERE THUNDERSTORM WATCH 104...

   VALID 260937Z - 261100Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 104
   CONTINUES.

   SUMMARY...SEVERE HAIL WILL REMAIN THE PRIMARY SHORT-TERM THREAT WITH
   A STORM CLUSTER ALONG THE NORTHEAST KS/SOUTHEAST NEB BORDER. BY
   ABOUT 12Z...STRONG TO ISOLATED SEVERE WIND GUSTS MAY ALSO DEVELOP
   AND POTENTIAL EXISTS FOR A DOWNSTREAM WW ISSUANCE INTO WEST MO.

   DISCUSSION...SEVERAL UPDRAFTS WITH FEW EMBEDDED SUPERCELLS HAVE
   CONGEALED INTO A CLUSTER ALONG THE NORTHEAST KS/SOUTHEAST NEB
   BORDER. THIS CORRIDOR REMAINS WITHIN A CONDUCIVE ENVIRONMENT FOR
   LARGE HAIL...ALONG THE PERIPHERY OF THE EML/VERY STEEP MID-LEVEL
   LAPSE RATES AND LOW-LEVEL INFLOW OF MODERATE TO LARGE BUOYANCY GIVEN
   THE GULF MOISTURE PLUME ACROSS CENTRAL KS. WITH THE TRANSITION TO A
   PREDOMINANT CLUSTER MODE...HAIL SIZE GROWTH WILL PROBABLY BE LIMITED
   BY DESTRUCTIVE INTERFERENCE...BUT ISOLATED SIGNIFICANT SEVERE HAIL
   WILL REMAIN POSSIBLE ESPECIALLY ALONG THE SOUTH/WEST FLANKS. DESPITE
   THE ELEVATED NATURE OF THE CLUSTER AT PRESENT...AMALGAMATION OF COLD
   POOLS MAY SUPPORT A FORWARD-PROPAGATING MCS ALONG THE MUCAPE
   GRADIENT TOWARDS THE KANSAS CITY METRO AREA...A SCENARIO REASONABLY
   SIMULATED BY 00Z WRF-NSSL. GIVEN PRESENCE OF 60-65 DEGREE F SURFACE
   DEW POINTS SOUTH OF THE FRONT...A THREAT FOR STRONG TO ISOLATED
   SEVERE WIND GUSTS MAY DEVELOP IN ADDITION TO THE OVERARCHING HAIL
   HAZARD.
