   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 249
   NWS Storm Prediction Center Norman OK
   440 PM CDT Sat Jun 30 2018

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Western Upper Michigan
     Northeastern into south central Wisconsin
     Lake Michigan
     Lake Superior

   * Effective this Saturday afternoon and evening from 440 PM until
     1100 PM CDT.

   * Primary threats include...
     Scattered large hail and isolated very large hail events to 2
       inches in diameter possible
     Scattered damaging wind gusts to 70 mph possible

   SUMMARY...Bands/clusters of storms are developing from Wisconsin
   into western Upper Michigan in a very unstable environment that will
   support a mix of organized multicell clusters/bowing segments and
   perhaps some embedded supercells.  Damaging winds and large hail
   will be the main threats through late evening as the storms spread
   east-northeastward.

   The severe thunderstorm watch area is approximately along and 60
   statute miles east and west of a line from 10 miles northwest of
   Marquette MI to 50 miles south southwest of Lonerock WI. For a
   complete depiction of the watch see the associated watch outline
   update (WOUS64 KWNS WOU9).

   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.
