   MESOSCALE DISCUSSION 0754
   NWS STORM PREDICTION CENTER NORMAN OK
   0852 PM CDT THU MAY 26 2016

   AREAS AFFECTED...SOUTH KS...WEST OK

   CONCERNING...TORNADO WATCH 214...216...

   VALID 270152Z - 270245Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 214...216...CONTINUES.

   SUMMARY...WITH WW/S 214 AND 216 SCHEDULED TO EXPIRE AT 03Z...SPC
   WILL COORDINATE WITH AFFECTED WFOS REGARDING WATCH REPLACEMENT
   AND/OR LOCAL TEMPORAL EXTENSION.

   DISCUSSION...NUMEROUS STRONG TO SEVERE STORMS ARE ONGOING FROM
   CENTRAL KS TO THE RED RIVER AREA OF SOUTHWEST OK/NORTHWEST TX.
   FARTHER EAST...A WEST-EAST/ORIENTED QLCS PERSISTS ALONG/NORTH OF
   LARGE-SCALE CONVECTIVE OUTFLOW ACROSS EAST-CENTRAL KS TO CENTRAL MO.
   A PLUME OF 65-69 DEG F SURFACE DEW POINTS IS PRESENT WITHIN A
   CONFINED CORRIDOR OF WEST OK ARCING INTO SOUTH KS. MODIFIED 00Z
   OUN/LMN RAOBS SUGGEST AMPLE MLCIN EXISTS EAST OF THIS MOISTURE PLUME
   ALONG THE I-35 CORRIDOR IN OK. THUS...OVERALL SPATIAL EXTENT OF THE
   SEVERE RISK SHOULD HOLD ACROSS AREAS ALREADY UNDER A WATCH FROM WEST
   OK AND SOUTH-CENTRAL KS. PRESENCE OF A 40-45 KT LOW-LEVEL JET WILL
   BE SUPPORTIVE OF ALL HAZARDS NEAR-TERM /ESPECIALLY WITH STORMS THAT
   CAN EVOLVE ALONG THE OUTFLOW BOUNDARY IN SOUTH-CENTRAL KS/.
   CONGLOMERATION OF COLD POOLS AND UPSCALE GROWTH INTO AN MCS SHOULD
   RESULT IN THE PREDOMINANT THREAT BEING STRONG TO SEVERE WIND GUSTS
   TOWARDS MIDNIGHT. THIS WOULD APPEAR MOST LIKELY ACROSS SOUTH KS INTO
   PERHAPS FAR NORTH OK.
