   0945 PM CDT FRI JUN 05 2015

   AREAS AFFECTED...NWRN KS

   CONCERNING...TORNADO WATCH 260...

   VALID 060245Z - 060345Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 260 CONTINUES.

   SUMMARY...A SUPERCELL TORNADO RISK WILL CONTINUE ACROSS PARTS OF
   NWRN KS AS UNIMPEDED NEAR-STORM ENVIRONMENT IS MAINTAINED IN
   FAVORABLE SHEAR/BUOYANCY.

   DISCUSSION...SUBJECTIVE SURFACE MESOANALYSIS PLACES A RESIDUAL
   EFFECTIVE BOUNDARY ACROSS CNTRL KS INTO NWRN KS WITH RICH LOW-LEVEL
   MOISTURE CONFINED TO THE NORTH SIDE OF THE BOUNDARY AND CO-LOCATED
   WITH BACKED EASTERLY SURFACE WINDS.  A STRENGTHENING IN THE LOW
   LEVEL JET IS FORECAST THIS EVENING AND KDDC IS BEGINNING TO SHOW
   FLOW AROUND 30 KT AT 0.5 KM ARL FROM THE SOUTH.  THE STRONGLY
   VEERING AND STRENGTHENING FLOW IN THE LOWER TROPOSPHERE --RESULTING
   IN ENHANCED SHEAR-- COUPLED WITH FAVORABLE BUOYANCY WILL LIKELY
   SUPPORT A SUPERCELL TORNADO RISK /PERHAPS STRONG/ BEFORE A GRADUAL
   DECOUPLING OF THE BOUNDARY LAYER OCCURS.
