   VALID 222102Z - 222200Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 335...336...CONTINUES.
   
   MOST INTENSE TSTM DEVELOPMENT OCCURRING ACROSS TORNADO WATCH 335
   ATTM WHERE PARTICULARLY INTENSE SUPERCELLS WERE TRACKING NNEWD
   ACROSS PARTS OF HASKELL...FINNEY...SCOTT AND GOVE COUNTIES. THESE
   CELLS APPEAR TO BE OCCURRING IN GENERALLY PRISTINE ENVIRONMENT WHERE
   INSTABILITY AND LOW LEVEL SHEAR WILL SUPPORT SUSTAINED MESOCYCLONES
   AND TORNADIC THREAT...ESPECIALLY NEAR DISCRETE CELLS...AND WITH
   CELLS NEAR/CROSSING WARM FRONT...NORTH OF GOVE/SHERIDAN COUNTY
   CONVECTION.
   
   ACTIVITY ACROSS NWRN KS APPEARS TO HAVE BEEN AFFECTED BY WWD MOVING
   OUTFLOW FROM STORMS FARTHER EAST. HOWEVER...INTENSELY SHEARED
   ENVIRONMENT NEAR DRYLINE/WARM FRONT INTERSECTION OVER CHEYENNE
   COUNTY IN NW KS...AND INTO DUNDY COUNTY NEB...COULD SUPPORT TORNADIC
   SUPERCELL IN THIS REGION NEXT HOUR.
   
   FARTHER SOUTH...ACROSS WATCH 336...A FEW STORM UPDRAFTS HAVE
   INITIATED ALONG THE DRYLINE ACROSS THE ERN TX PNHDL. OTHER THAN DEEP
   MIXING ALONG THE DRYLINE...FORCING TO AID ADDITIONAL STORM
   DEVELOPMENT AND SUSTENANCE THIS AREA IS SUBTLE/WEAK. HOWEVER...MODEL
   SOUNDINGS ACROSS WATCH 336 REVEAL LITTLE CONVECTIVE INHIBITION IS
   LEFT GIVEN CURRENT SURFACE CONDITIONS. THIS IS DESPITE GENERALLY
   WARM MID LEVEL TEMPERATURES /700MB TEMPS 10C-12C/. GIVEN SATELLITE
   AND RADAR TRENDS...AND LATEST GUIDANCE...THE THREAT FOR SEVERE
   STORMS WITH LARGE HAIL AND PERHAPS A COUPLE OF TORNADOES WILL LIKELY
   INCREASE GRADUALLY ACROSS WATCH 336 OVER THE NEXT SEVERAL HOURS.
