...Today in metro Denver weather history...

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
        minimum for the date.
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 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
        to 32 mph with gusts to 41 mph reduced the visibility to
        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
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
        Stapleton Airport where north winds sustained to 28 mph
        produced some blowing snow...snowfall totaled 8.8 inches.
18-20 In snowfall totaled 6.9 inches in downtown
        Denver over the 3 days.  Most of the snow fell on the 19th.
        Northeast winds were sustained to 21 mph with a measured
        extreme velocity to 24 mph on the 18th.
      In 1924...light snowfall totaled 4.6 inches over the 3 days.
        This was the only measurable snowfall of the month.  High
        temperatures plunged from 45 degrees on the 18th to 17
        degrees on the 20th.  Low temperatures dipped from 31
        degrees on the 18th to only 8 degrees on the 20th.
        Northeast winds were sustained to 24 mph on the 19th.
      In 1953...a major blizzard dumped 10.6 inches of snowfall at
        Stapleton Airport.  Strong north winds at sustained speeds
        of 25 to 35 mph with gusts as high as 44 mph frequently
        reduced visibilities to 1/4 mile in blowing snow during the
        day of the 19th.  The strong winds caused much drifting
        snow...making accurate snowfall measurements almost
        impossible.  Precipitation from the storm totaled 1.13
        inches.  The 1.01 inches of precipitation on the 19th
        was the greatest calendar day and 24 hour precipitation
        ever recorded in the city during the month of February.
      In 1987...large amounts of new snow fell in the Front Range
        foothills.  The foothills received 10 to 20 inches of new
        snow with 4 to 8 inches on the adjacent plains.  On the
        19th...flight delays occurred at Stapleton International
        Airport where snowfall totaled 4.2 inches and east winds
        gusted to only 18 mph on the 19th.  Schools were closed
        in the foothills above Boulder.
