   Areas affected...western and north-central KS

   Concerning...Tornado Watch 492...

   Valid 030014Z - 030215Z

   The severe weather threat for Tornado Watch 492 continues.

   SUMMARY...Scattered thunderstorms with embedded supercells have
   developed across west-central KS.  These storms are capable of
   producing large hail, damaging wind gusts, and a perhaps a few
   tornadoes. A tornado watch remains in effect.

   DISCUSSION...Rigorous thunderstorm development continues to occur
   within a moderately unstable airmass, where MLCAPE ranges from
   1500-2000 J/kg, and impressive effective bulk shear exceeding 60 kt.
   Low-level shear should continue to increase this evening as shown on
   the Goodland VWP, where 0-1 km shear is near 40 kt and some
   strengthening of the winds has occurred just above the surface. The
   low-level jet should intensify this evening, helping to increase the
   tornado potential, particularly for the ongoing supercell and any
   other storm that becomes anchored along the north-east oriented
   surface boundary.
