   CONCERNING...SEVERE POTENTIAL...WATCH LIKELY 
   
   VALID 091847Z - 092045Z
   
   TRENDS ARE BEING MONITORED FOR AN INCREASING SEVERE THREAT THAT
   COULD REQUIRE A WATCH WITHIN THE NEXT 1 TO 2 HOURS.
   
   MOIST SOUTHEASTERLY UPSLOPE FLOW AND DAYTIME HEATING CONTINUE TO
   CONTRIBUTE TO BOUNDARY LAYER DESTABILIZATION.  CONSIDERABLE
   INHIBITION REMAINS...BUT IT APPEARS THAT THIS MAY WEAKEN
   SUFFICIENTLY FOR THE INITIATION OF AT LEAST WIDELY SCATTERED
   BOUNDARY LAYER BASED STORMS WITHIN THE NEXT FEW HOURS.  DEEPENING
   CONVECTION IS ALREADY EVIDENT ALONG THE FRONT RANGE...AND FORCING
   FOR UPWARD VERTICAL MOTION ASSOCIATED WITH THE APPROACH OF A SHORT
   WAVE TROUGH PROBABLY WILL AID DEVELOPMENT LATE THIS AFTERNOON.  IN
   THE PRESENCE OF MIXED LAYER CAPE ON THE ORDER OF 1000-2000
   J/KG...DEEP LAYER SHEAR BENEATH 30+ KT WEST NORTHWESTERLY 500 MB
   FLOW IS STRONG...AND CONDUCIVE TO SUPERCELLS.  THIS APPEARS POSSIBLE
   AS EARLY AS 20-22Z... PARTICULARLY ALONG THE INTERSTATE 80 CORRIDOR
   AROUND SIDNEY NEB.
