   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 525
   NWS Storm Prediction Center Norman OK
   550 PM CDT Fri Jul 19 2019

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Much of north central and northeastern Wisconsin
     Lake Michigan

   * Effective this Friday afternoon and Saturday morning from 550
     PM until 100 AM CDT.

   ...THIS IS A PARTICULARLY DANGEROUS SITUATION...

   * Primary threats include...
     Widespread damaging winds and scattered significant gusts to 105
       mph expected
     Scattered large hail and isolated very large hail events to 2.5
       inches in diameter possible
     A few tornadoes likely

   SUMMARY...An intense supercell cluster in northwestern Wisconsin is
   expected to evolve into a damaging bow echo that will accelerate
   east-southeastward across northern/northeastern Wisconsin this
   evening.  The storm environment will favor swaths of high-end,
   destructive outflow winds potentially exceeding 100 mph.  Tornadoes
   will also be possible with embedded circulations, as well as large
   hail in the next few hours with lingering supercell structures.

   The severe thunderstorm watch area is approximately along and 55
   statute miles north and south of a line from 70 miles west northwest
   of Wausau WI to 30 miles northeast of Manitowoc WI. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU5).

   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 523...WW 524...

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   2.5 inches. Extreme turbulence and surface wind gusts to 90 knots. A
   few cumulonimbi with maximum tops to 650. Mean storm motion vector
   29050.
