Snow for Columbus Day Weekend

Winter Weather comes to Wyoming this weekend. With a relatively large and cold Low pressure system moving into the Rockies on Saturday, then hanging out over the Central Rockies Sunday into Monday. This will create an “upslope” flow pattern against the Continental Divide.
