   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 501
   NWS Storm Prediction Center Norman OK
   155 PM EDT Fri Oct 23 2020

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Parts of northeast and east central Indiana
     Southeast Lower Michigan
     Parts of western and northern Ohio
     Lake Erie
     Lake Huron

   * Effective this Friday afternoon and evening from 155 PM until
     900 PM EDT.

   * Primary threats include...
     Scattered damaging wind gusts to 70 mph possible
     Isolated large hail events to 1 inch in diameter possible
     A tornado or two possible

   SUMMARY...Bands of thunderstorms will intensify this afternoon while
   spreading eastward along and just ahead of a cold front.  The storm
   environment favors the potential for damaging winds with the
   stronger embedded cells/line segments.  Isolated large hail will
   also be possible, and an brief tornado cannot be ruled out.

   The severe thunderstorm watch area is approximately along and 70
   statute miles east and west of a line from 80 miles north northeast
   of Mount Clemens MI to 25 miles south southwest of Dayton OH. 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.

   &&

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   1 inch. Extreme turbulence and surface wind gusts to 60 knots. A few
   cumulonimbi with maximum tops to 500. Mean storm motion vector
   25035.
