        after falling continuously for 48 hours and totaling an
        estimated 13 inches in the city. The storm... likely
        accompanied by strong winds... caused trains to be delayed
        for 2 to 3 days. One or two roofs of small buildings were
        crushed by the weight of the snow... and many tree branches
        were broken in the city. There were a number of reports of
        livestock losses. One Stockman lost 17 horses and several

        injury to foliage and blossoms... but some of the early
        Cherry and apple blossoms were injured. Rain changed to

        27th. Snowfall totaled only 2.0 inches and northeast winds
        gusted to 22 mph on the 26th.

        power lines. Sustained winds of 37 mph with gusts of 50 to
        60 mph were recorded in Metro Denver. West-northwest winds
        gusted to 44 mph at Stapleton International Airport on the
        26th.
27 in 1955... west winds at 43 mph with gusts as high as 55 mph

      In 1966... a northwest wind gust to 51 mph was recorded at
        Stapleton International Airport.
27-28 in 1919... rainfall totaled 2.03 inches for the two days...
        along with a trace of snowfall. Northwest winds were
        sustained to 24 mph with gusts to 26 mph on the 27th.
      In 1975... high winds gusting to 85 mph severely damaged a
        Mobile home in Boulder and caused other minor damage.
        West winds gusted to 46 mph at Stapleton International
        Airport on the 28th.
      In 1996... heavy snow fell over portions of the Front Range
        foothills west of Denver. Snowfall amounts ranged from
