A slow moving winter storm system progressed eastward through the area.  Due to the rather warm conditions ahead of the system, the precipitation changed from rain to snow.  Heavy rainfall on the already saturated ground from the plentiful seasonal snowfall and slow moving storms caused localized flooding for parts of the area.  High winds also accompanied the rain and snow.  The combination of high winds and heavy snow caused locations in and near Bosler, Laramie and Chugwater, in southern Platte and central Albany county, to lose power.  The only life lost from this storm 14 calves.
