occurring on the 8th. East winds gusted to 37 mph on the
9th. Temperatures dipped into the single digits on the
mornings of the 7th and 12th when 7 degrees were

across eastern Colorado with 10 to 20 inches in the
foothills and 4 to 8 inches over the plains. Winds to
35 mph combined with the snow to produce drifts at least
