An abnormally strong and cold low pressure system and associated cold front dropped south across the Northern Rockies and into the Four Corners. The low remained quasi-stationary for about a day before lifting northeast into the Plains. This system produced widespread showers of rain in the lower elevations and snow in the mountains, though the cold front dropped snow levels to approximately 7000 feet. Additionally, high winds led to not only reduced visibility in blowing snow, but also numerous downed trees and power outages in some areas.
