   * Severe Thunderstorm Watch for portions of 
     Southeastern Montana

   any of the stronger embedded/supercell storms.

   The severe thunderstorm watch area is approximately along and 95
   statute miles east and west of a line from 30 miles northwest of

   depiction of the watch see the associated watch outline update

   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.
