   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 689
   NWS Storm Prediction Center Norman OK
   455 PM EDT Sun Oct 6 2024

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Western New York
     Eastern Ohio
     Western Pennsylvania
     Northern West Virginia Panhandle

   * Effective this Sunday afternoon and evening from 455 PM until
     1100 PM EDT.

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

   SUMMARY...Scattered thunderstorms are forecast to continue to
   develop and intensify through the afternoon and into the evening
   across the Watch area.  A few of the stronger thunderstorms will
   likely acquire supercell characteristics and pose an initial risk
   for large hail (1 to 2 inches in diameter) and localized severe
   gusts.  Upscale growth into a mix of cells and linear segments this
   evening will facilitate the severe risk potentially becoming
   primarily a damaging wind threat (60 to 70 mph gusts) before this
   activity weakens late this evening.

   The severe thunderstorm watch area is approximately along and 60
   statute miles east and west of a line from 30 miles north of Buffalo
   NY to 35 miles south of Wheeling WV. 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.

   &&

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   2 inches. Extreme turbulence and surface wind gusts to 60 knots. A
   few cumulonimbi with maximum tops to 450. Mean storm motion vector
   26040.
