  will also be possible with circulations embedded in the line of
  storms.
  
  The severe thunderstorm watch area is approximately along and 65
  statute miles north and south of a line from 30 miles northeast of
  Massena NY to 40 miles south southwest of Jamestown NY. For a
  complete depiction of the watch see the associated watch outline
  update (WOUS64 KWNS WOU7).

  REMEMBER...A Severe Thunderstorm Watch means conditions are
  favorable for severe thunderstorms in and close to the watch area.

  weather conditions and listen for later statements and possible
  warnings. Severe thunderstorms can and occasionally do produce
  tornadoes.
