   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Western Colorado

   * Effective this Saturday morning and afternoon from 950 AM until

   SUMMARY...Thunderstorms will increase in coverage and intensity from

   north-northeastward across eastern Utah and western Colorado.  The
   storm environment will favor a mix of both supercells and bowing
   line segments capable of producing damaging winds and large hail. 
   An isolated tornado cannot be ruled out.

   The severe thunderstorm watch area is approximately along and 125
   statute miles east and west of a line from 55 miles northeast of
   Vernal UT to 25 miles southwest of Cortez CO. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU0).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   REMEMBER...A Severe Thunderstorm Watch means conditions are
   favorable for severe thunderstorms in and close to the watch area.
   Persons in these areas should be on the lookout for threatening
   weather conditions and listen for later statements and possible
   warnings. Severe thunderstorms can and occasionally do produce
   tornadoes.

   1.5 inches. Extreme turbulence and surface wind gusts to 65 knots. A
