   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 122
   NWS Storm Prediction Center Norman OK
   535 PM MDT Sat May 26 2018

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Eastern Montana
     Western North Dakota

   * Effective this Saturday afternoon and Sunday morning from 535
     PM until 100 AM MDT.

   * Primary threats include...
     Scattered damaging winds likely with isolated significant gusts
       to 75 mph possible
     Scattered large hail and isolated very large hail events to 2
       inches in diameter possible

   SUMMARY...Isolated to scattered storms should initially develop
   across parts of northeast Montana with a risk for severe hail and
   locally strong gusts. This activity will likely develop into a
   forward-moving cluster with embedded linear, bowing segments
   potentially producing severe wind gusts later this evening across
   parts of eastern Montana into western North Dakota.

   The severe thunderstorm watch area is approximately along and 60
   statute miles north and south of a line from 30 miles south
   southwest of Glasgow MT to 30 miles east of Dickinson ND. For a
   complete depiction of the watch see the associated watch outline
   update (WOUS64 KWNS WOU2).

   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.

   &&

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   2 inches. Extreme turbulence and surface wind gusts to 65 knots. A
   few cumulonimbi with maximum tops to 500. Mean storm motion vector
   28035.
