Wider weather episode

A slow moving upper low moved across Wyoming on the 17th and 18th. Very strong dynamics were associated with this low which also resulted in strong dynamic cooling. The low produced a deep upslope flow into the Crazy and Beartooth/Absaroka Mountains and adjacent foothills. As a result, very heavy, wet snow occurred across portions of these areas. In addition, the weight of the heavy, wet snow resulted in downed tree limbs and power lines resulting in power outages across portions of Park County.
