   MESOSCALE DISCUSSION 1003
   NWS STORM PREDICTION CENTER NORMAN OK
   1122 PM CDT SAT JUN 14 2014

   AREAS AFFECTED...NERN KS...SERN NEB THROUGH WRN IA

   CONCERNING...TORNADO WATCH 294...

   VALID 150422Z - 150515Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 294 CONTINUES.

   SUMMARY...THREAT FOR WIDESPREAD DAMAGING WIND...LARGE HAIL AND A
   COUPLE BRIEF TORNADOES WILL PERSIST INTO THE EARLY MORNING FROM NERN
   KS INTO SERN NEB AND WRN IA. TORNADO WATCH 294 WILL BE REPLACED BY
   ANOTHER WW BEFORE ITS EXPIRATION TIME OF 05Z.

   DISCUSSION...STORMS HAVE EVOLVED INTO A DOMINANT LINEAR MCS ACROSS
   SCNTRL NEB INTO NCNTRL KS MOVING EAST AROUND 40 KT. AN MCV WAS
   INDICATED ON THE NRN END OF THIS LINE OVER SCNTRL NEB. FARTHER
   EAST...STORMS DEVELOPING WITHIN THE ZONE OF WARM ADVECTION OVER NERN
   NEB HAVE MOSTLY CONGEALED INTO CLUSTERS...BUT A FEW SUPERCELL
   STRUCTURE REMAIN. DESPITE THE CAPPING INVERSION DOWNSTREAM...INTENSE
   CONVERGENCE ALONG THE LEADING GUST FRONT AUGMENTED BY A 60 KT SLY
   LLJ WILL MAINTAIN A FORWARD PROPAGATING SYSTEM NEXT SEVERAL HOURS.
   STORMS ARE EMBEDDED WITHIN STRONG DEEP LAYER WINDS WITH LARGE
   LOW-LEVEL HODOGRAPHS SUPPORTIVE OF BOWING SEGMENTS AND
   MESO-VORTICES. THE PRIMARY THREAT HAS TRANSITIONED TO WIDESPREAD
   DAMAGING WIND INCLUDING POTENTIAL FOR A FEW 70+ KT WIND GUSTS...BUT
   ISOLATED LARGE HAIL MAY STILL OCCUR. A COUPLE OF BRIEF TORNADOES
   REMAIN POSSIBLE...ESPECIALLY WHERE NRN END OF SQUALL LINE INTERSECTS
   REMNANT OUTFLOW BOUNDARY ACROSS ERN NEB.
