A strong low pressure system moved slowly across southern California and Arizona and then moved east northeast across southeast Colorado. Deep moisture was transported across western Colorado ahead of this system and continued to wrap around the low pressure center as it moved east of the area. The moist and unstable atmosphere along with a strong upper level jet resulted in moderate to heavy snow across the area with strong winds over some of the high terrain.
