MESOSCALE DISCUSSION 0963
   NWS STORM PREDICTION CENTER NORMAN OK
   0236 AM CDT WED JUN 05 2013

   AREAS AFFECTED...W CENTRAL AND N CENTRAL OK...S CENTRAL KS

   CONCERNING...SEVERE THUNDERSTORM WATCH 278...

   VALID 050736Z - 050900Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 278
   CONTINUES.

   SUMMARY...A WELL-DEVELOPED MCS WILL CONTINUE TO MOVE ESEWD TOWARD
   THE I-35 CORRIDOR IN NRN OK/SRN KS...WITH A CONTINUED RISK FOR
   OCCASIONAL DAMAGING WINDS AND ISOLATED LARGE HAIL.

   DISCUSSION...THE STRONG/SEVERE MCS CONTINUE TO MOVE ESEWD AT CLOSE
   TO 40 KT ACROSS NW/N CENTRAL OK AND ADJACENT AREAS OF SRN KS...WITH
   NEW STORM DEVELOPMENT OCCURRING S OF THE WATCH BETWEEN FSI AND OKC. 
   THE SRN FLANK OF THE MCS IS MOVING THROUGH THE MOST FAVORABLE STORM
   ENVIRONMENT NOW...WITH A SLOW INCREASE IN BOUNDARY LAYER CONVECTIVE
   INHIBITION WITH TIME DOWNSTREAM FROM THE STORMS IN OK.  STILL...THE
   40 KT LLJ OBSERVED IN LOCAL PROFILER/VWP DATA WILL SUPPORT STRONG
   ASCENT ALONG THE GUST FRONT AND COULD ALLOW SOME ADDITIONAL SWD
   DEVELOPMENT CLOSER TO I-40 IN W CENTRAL OK DURING THE NEXT COUPLE OF
   HOURS.  LONGER TERM...THE MCS IS EXPECTED TO CONTINUE INTO CENTRAL
   AND NE OK EARLY THIS MORNING...AND WILL LIKELY PERSIST BEYOND THE
   10Z WATCH EXPIRATION.  HOWEVER...THE DAMAGING WIND/HAIL PROSPECTS
   SHOULD BECOME MARGINAL BY THAT TIME /09-10Z/...SUCH THAT THE NEED
   FOR A NEW DOWNSTREAM WATCH IS NOT CLEAR.

   FARTHER NW INTO THE NE TX PANHANDLE...SOME CONVECTION CONTINUES TO
   DEVELOP IN A ZONE OF ELEVATED ASCENT ABOVE THE COLD POOL TRAILING
   THE MCS.  ISOLATED LARGE HAIL WILL BE POSSIBLE WITH THESE STORMS AS
   THEY DEVELOP SEWD FOR THE NEXT FEW HOURS...BUT A NEW WW FOR THIS
   AREA APPEARS UNLIKELY.
