   455 PM MDT Tue Aug 6 2024

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Northern into Central and Eastern Montana

     MDT.

   * Primary threats include...
     Scattered damaging wind gusts to 70 mph possible

   SUMMARY...Widely scattered to scattered thunderstorms will continue

   some outflow merging and upscale growth into one or more clusters is
   expected later this evening.  Severe gusts (60-70 mph) and perhaps
   large hail may accompany this activity late this evening into the
   early overnight.

   The severe thunderstorm watch area is approximately along and 90
   statute miles north and south of a line from 75 miles north
   northwest of Drummond MT to 20 miles northeast of Glendive MT. For a
   complete depiction of the watch see the associated watch outline
   update (WOUS64 KWNS WOU9).

   favorable for severe thunderstorms in and close to the watch area.
   Persons in these areas should be on the lookout for threatening

   tornadoes.
