        blowing dust. This red dust became entrained in snowfall
        across the area. The reddish colored snow was reported

        Denver and Morrison described the event as the most severe
        storm of the winter while it lasted.
      In 1885... a windstorm caused severe damage in the city. The

        departing winter storm. A wind gust to 91 mph was recorded

        west of Denver. West winds gusted to only 20 mph at
        Stapleton International Airport.

        and Lafayette. Limited minor damage and a few injuries
        occurred.
      In 1986... strong Chinook winds continued to howl in the
        foothills. A wind gust to 89 mph was recorded at Table
        Mesa in Boulder on the 16th. Winds of 60 to 75 mph were
        clocked at other locations in Boulder on both days.
        A west wind gust to 51 mph was recorded at Stapleton
        International Airport on the 16th.
16-18 in 1970... a wind gust to 90 mph was recorded in Boulder at the
        National center for atmospheric research. In downtown
        Boulder... sustained winds of 30 to 40 mph with gusts to 53
        mph were measured. Damage was minor. West winds gusted
        to 45 mph at Stapleton International Airport on the 17th.
        The strong Chinook winds warmed the temperature to 70
        degrees on the 16th and to 72 degrees on the 17th... both
        records for the date. The low temperature dipped to
        only 32 degrees on the 16th equaling the record high

        plate-glass windows in downtown Denver office buildings.
      In 1962... heavy snowfall totaled 7.5 inches at Stapleton
        Airport where the visibility was reduced to as low as
        1/4 mile at times. Winds gusted from the northeast at
        only 15 mph.
      In 2009... strong prefrontal wind gusts knocked down some trees
        and power lines in Boulder. More than 3400 xcel customers
        in the univerity hill area were without power for about one
        hour. Peak wind gusts included 68 mph at the ncar Mesa lab
        and 60 mph in Boulder.
17-18 in 1976... a strong cold front produced wind gusts 30 to 60 mph
        with much blowing snow and severe dust storms. In the
        Boulder area... high winds collapsed a garage and broke some
        windows. Northwest winds gusted to 43 mph on the 17th and
        to 44 mph on the 18th at Stapleton International Airport.
      In 1984... the third blizzard in a week struck eastern
        Colorado. Heavy snow hit some parts of Metro Denver
        with 8 to 10 inches measured in Aurora... but only 2.9 inches
        of snow fell at Stapleton International Airport where
        northwest winds gusted to 31 mph.
      In 1999... damaging downslope bora winds developed in the
        foothills behind a strong cold front. Peak wind reports
        included: 90 mph at the gamow tower on the University of
        Colorado Campus in boulder; 79 mph at the National center
        for atmospheric research Mesa lab near Boulder and at the
        National wind technology center south of boulder; and 72
        mph atop Blue Mountain and at Jefferson County Airport.
        Downed power lines caused major outages for at least 10
        thousand residents in Evergreen... Idaho Springs... Golden...
        and Lakewood. In Golden... the wind toppled a lightning
        static protection line atop a 70-foot... 230 thousand-volt
        distribution tower. The downed line... sparked a small
        grass fire just east of the Lookout Mountain youth services
        center. The fire burned a path approximately 100 yards
        wide and 1/3 mile long before it was contained.
      In 2000... snow... heavy in the mountains and foothills... spread
        over Metro Denver. Snowfall totaled 24 inches at the Eldora
        ski resort with 8 inches measured near Blackhawk. Snowfall
        was only 1.8 inches at the site of the former Stapleton
        International Airport... which was the only measurable snow
        of the month.
17-19 in 2006... a cold spell resulted in 4 temperature records.
        Low temperatures of 10 degrees below zero on the 17th...
        13 degrees below zero on the 18th... and 4 degrees below
        zero on the 19th were record minimums for those dates.
        The high temperature of only 7 degrees on the 18th was
        a record low maximum for the date. Light snow fell on
        the 17th... but totaled less than half an inch at Denver
        International Airport.
18 in 1918... Post-frontal northwest winds were sustained to 40
        mph with a measured extreme velocity to 44 mph.
      In 1937... a moderate duststorm occurred during the late
        afternoon and early evening. Northeast winds sustained

        1/2 mile which persisted for about 40 minutes in the city.
      In 1998... rare thunder from instability rain and snow showers
        was heard in Littleton during the late afternoon. Thunder
        in February only occurs about once every 10 years over Metro
        Denver.
18-19 in 1954... a vigorous cold front produced north winds gusting
        to 56 mph and a trace of snowfall at Stapleton Airport on
        the 18th. Strong and gusty winds to 55 mph persisted
        through the next day and caused some blowing dust.
      In 1955... a storm dumped heavy snow across Metro Denver. At
