   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 341
   NWS Storm Prediction Center Norman OK
   745 PM CDT Fri Jun 16 2017

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     South-central Iowa
     Northeast and eastern Kansas
     Western and Northern Missouri

   * Effective this Friday night and Saturday morning from 745 PM
     until 400 AM CDT.

   * Primary threats include...
     Widespread damaging winds likely with isolated significant gusts
       to 85 mph possible
     Scattered large hail likely with isolated very large hail events
       to 2 inches in diameter possible
     A tornado or two possible

   SUMMARY...An intense linear convective system, responsible for a
   measured 88 mph wind gust at the Omaha-Valley National Weather
   Service office, will likely continue to expand and accelerate
   southeastward this evening as it races into northeast/eastern Kansas
   and western/northern Missouri, potentially including the Kansas City
   Metro area, as well as parts of south-central Iowa. Widespread wind
   damage seems likely this evening into the overnight in these areas,
   along with some embedded tornado risk in addition to isolated
   instances of large hail.

   The severe thunderstorm watch area is approximately along and 75
   statute miles east and west of a line from 50 miles north northeast
   of Des Moines IA to 50 miles south southwest of Olathe 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.
