A large and unseasonably moist low pressure system lifted across the Four Corners region. Favorable southerly flow during the onset of the event produced moderate to heavy snow over the southern mountains and some valleys. Once cooler air moved into the region during the latter half of the storm, snowfall began to favor the northern and central Colorado mountains. Wind gusts exceeded 45 MPH at times.
