Seattle had a top 10 in Dec 68 and 2 in Jan 69. Three top 10's in one winter. That's why that was my favorite winter. It was a lot like that here in Portland also.
El Paso is over 3,700 ft. They get under 10 inches of precip a year with about 7 inches of it being snow, which is more than most lowland locations on the I-5 corridor in the PNW. Amarillo averages about 18 inches of snow per year.
