   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 271
   NWS Storm Prediction Center Norman OK
   635 PM MDT Fri May 26 2017

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Western Kansas
     Southwest Nebraska

   * Effective this Friday night and Saturday morning from 635 PM
     until 200 AM MDT.

   * Primary threats include...
     Isolated very large hail events to 2.5 inches in diameter
       possible
     Isolated damaging wind gusts to 70 mph possible
     A tornado or two possible

   SUMMARY...Relatively isolated storms including a couple of
   supercells ongoing across eastern CO early this evening will
   continue east-southeastward into western Kansas this evening.
   Gradual storm mergers and a gradually increasing low-level jet may
   support the evolution of one or more semi-organized
   east/southeastward-moving complexes of storms. Large hail and
   locally damaging winds will be the main risks.

   The severe thunderstorm watch area is approximately along and 35
   statute miles east and west of a line from 20 miles east of Imperial
   NE to 30 miles west southwest of Garden City KS. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU1).

   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.

   OTHER WATCH INFORMATION...CONTINUE...WW 268...WW 269...WW 270...

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   2.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A
   few cumulonimbi with maximum tops to 500. Mean storm motion vector
   28025.
