   MESOSCALE DISCUSSION 0626
   NWS STORM PREDICTION CENTER NORMAN OK
   0514 PM CDT FRI MAY 13 2016

   AREAS AFFECTED...SE KS...NCNTRL MO

   CONCERNING...SEVERE THUNDERSTORM WATCH 174...

   VALID 132214Z - 140015Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 174
   CONTINUES.

   SUMMARY...AN ISOLATED SEVERE THREAT WILL LIKELY CONTINUE FROM SE KS
   EXTENDING NEWD ACROSS NCNTRL MO LATE THIS AFTERNOON INTO EARLY THIS
   EVENING. WIND DAMAGE AND HAIL WILL BE THE PRIMARY THREATS. WW 174
   SHOULD CONTAIN THE SEVERE WEATHER THREAT THROUGH THE 0100Z
   EXPIRATION AND A NEW WW IS NOT EXPECTED.

   DISCUSSION...LATEST SFC ANALYSIS SHOWS A 1011 MB LOW OVER NE MO WITH
   A COLD FRONT EXTENDING SWWD ACROSS NCNTRL MO INTO ECNTRL KS. A
   CORRIDOR OF LOW-LEVEL MOISTURE IS PRESENT JUST AHEAD OF THE FRONT
   WITH SFC DEWPOINTS RANGING FROM THE MID 50S F IN SE KS TO THE UPPER
   40S F IN NE MO. DUE TO THE RELATIVELY DRY AIRMASS...ONLY WEAK
   INSTABILITY IS IN PLACE AHEAD OF THE FRONT...ESPECIALLY ACROSS NE MO
   WHERE THE SEVERE THREAT IS ALREADY MARGINAL. FURTHER TO THE
   SOUTHWEST...THE WSR-88D VWP AT KANSAS CITY SHOWS O-6 K SHEAR NEAR 50
   KT WITH SOUTHWEST FLOW AT THE SFC GRADUALLY VEERING TO THE WEST
   NORTHWEST IN THE MID-LEVELS. THIS WIND PROFILE SHOULD CONTINUE TO BE
   FAVORABLE FOR MULTICELL STORM MODE WITH SOME LINEAR ORGANIZATION.
   THE STRONG DEEP-LAYER SHEAR COMBINED WITH STEEP LAPSE RATES SHOULD
   MAKE DAMAGING WIND GUSTS POSSIBLE WITH THE STRONGER DOWNDRAFTS. DUE
   TO THE STEEP LAPSE RATES AND COLD AIR ALOFT WITH 500 MB TEMPS OF -15
   TO -18C...HAIL MAY ALSO OCCUR WITH THE MORE INTENSE CORES.
