   OTHER WATCH INFORMATION...CONTINUE...WW 509...

   DISCUSSION...TSTMS ARE EXPECTED TO DEVELOP OFF THE HIGH TERRAIN AS
   WELL AS INVOF THE LEE CYCLONE AND ATTENDANT QUASI-STATIONARY FRONT
   AS LARGE-SCALE FORCING FOR ASCENT INCREASES AHEAD OF A STRONG
   SHORT-WAVE TROUGH MOVING THROUGH THE CNTRL AND SRN ROCKIES. LOCALLY
   BACKED NEAR-SURFACE FLOW COUPLED WITH THE POTENTIAL FOR STORMS TO
   INTERACT WITH THE STATIONARY FRONT SUGGEST A RISK FOR A COUPLE OF
   TORNADOES AS STORMS MATURE LATER THIS AFTERNOON INTO EVENING. WITH
   TIME...ACTIVITY SHOULD GROW UPSCALE INTO A CONVECTIVE SYSTEM WITH
   THE SEVERE WEATHER THREAT TRANSITIONING TO DAMAGING STRAIGHT LINE
   WINDS. LARGE HAIL WILL BE POSSIBLE IN BOTH REGIMES.

   AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
   SURFACE AND ALOFT TO 1.5 INCHES. EXTREME TURBULENCE AND SURFACE
   WIND GUSTS TO 60 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO
   400. MEAN STORM MOTION VECTOR 19030.
