   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 240
   NWS Storm Prediction Center Norman OK
   440 AM CDT Fri Jun 29 2018

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     North-central and Northeast Minnesota
     Northwest Wisconsin
     Lake Superior

   * Effective this Friday morning from 440 AM until 1100 AM CDT.

   * Primary threats include...
     Widespread damaging winds likely with isolated significant gusts
       to 75 mph possible
     A tornado or two possible

   SUMMARY...An intense and fast-moving (50+ mph) squall line/bow echo
   will continue generally eastward this morning across essentially all
   of northern Minnesota, and it eventually may reach western Lake
   Superior and northwest Wisconsin. Swaths of wind damage can be
   expected this morning even while this fast-moving wind-producing
   system may undergo a weakening trend later this morning.
   Additionally, a tornado or two cannot be ruled out with embedded
   circulations within the line.

   The severe thunderstorm watch area is approximately along and 90
   statute miles north and south of a line from 70 miles north
   northwest of Brainerd MN to 40 miles south southeast of Grand Marais
   MN. 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.
