This Hazardous Weather Outlook is for portions of central
Montana...south central Montana...southeast Montana and north
central Wyoming.

* Outlook: A period of wet and unsettled weather is expected
  tonight through Friday, with the heaviest precipitation being
  Thursday and Thursday night. Portions of the forecast area could
  see 0.50 to 1.50 inches of rain, with the heavier amounts likely
  over southern Big Horn county into Sheridan county. Snow is
  expected to accumulate over area mountains. The snow could be
  heavy at times over the Bighorns. Lower elevations could see
  some wet snow Thursday night, with some accumulation possible
  over the higher hills through early Friday.

* Potential Impacts: The combination of a wet ground, snow melt
  from recent lower elevation snowfall and additional rainfall,
  will likely cause rises on rivers and streams with some minor
  flooding possible through Saturday. Also, look for significant
  ponding of water in low lying areas and very muddy local roads,
  making travel difficult. Heavy snow in the Bighorns will make for
  very difficult travel and could cause power outages. Also, the
  chilly and wet weather could be stressful on young livestock.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Hazardous Weather Outlook is issued when hazardous weather could
impact the region within the next week. Be sure to stay tuned for
future updates as locations, timing, and impacts could change.
Begin preparations to mitigate any impacts that could result from
the hazardous weather.
