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

20-22 In 1944...heavy snow fell over metro Denver for a total of
        36 hours.  The storm dumped 18.5 inches of snowfall over
        downtown Denver and 12.2 inches at Stapleton Airport.
        Fortunately...there were no strong winds with the storm.
        North winds to only 19 mph were recorded on the 21st.
21-22 In 1955...wind gusts to 98 mph were recorded at Rocky Flats
        south of Boulder.  Some damage and a few minor injuries
        were reported in Boulder.  Northwest winds were sustained
        to 28 mph with gusts to 39 mph at Stapleton Airport on the
      In 1966...a vigorous cold front produced only 1.7 inches of
        snowfall at Stapleton International Airport...but northeast
        winds gusted to 49 mph on the 21st.  Temperatures cooled
        from a maximum of 66 degrees on the 21st to a minimum of
        14 degrees on the 22nd.  Strong winds occurred on both
      In Arctic cold front produced upslope snow across
        metro Denver mainly west of I-25.  Castle Rock reported 6
        inches of snow with 3 inches at Evergreen.  At Stapleton
        International Airport...only 1.5 inches of snowfall were
        measured and northeast winds gusted to 18 mph on the 21st.
22    In 1905...apparent post-frontal north winds were sustained to
        49 mph.
      In 1922...a vigorous cold front with north winds sustained to
        41 mph brought only 0.6 inch of snowfall to the city.
        These were the highest winds of the month.
      In 1966...high winds caused extensive blowing snow that
        impeded traffic and closed highways over a wide area of
        eastern Colorado.  Wind damage was widespread...but minor.
        North wind gusts to 47 mph were recorded at Stapleton
        International Airport where visibility was reduced as low
        as 1/8 mile in blowing snow.
      In 1975...a strong west wind gust to 51 mph was recorded at
        Stapleton International Airport...while east of Denver
        the strong winds caused minor property damage and
        considerable blowing dust which closed several roads.
      In 1979...near-blizzard conditions paralyzed the northeastern
        quarter of the state.  Strong winds and drifting snow
        closed many roads...including I-25 and I-70.  Power outages
        darkened sections of metro Denver.  Snow accumulations of
        4 to 12 inches were measured over the plains with drifts
        several feet deep.  Only 3.5 inches of snow were recorded
        at Stapleton International Airport where northeast winds
        gusted to 39 mph causing some blowing snow.
      In 1995...strong winds associated with a fast moving Pacific
        cold front moved from the mountains into metro Denver.
        Winds estimated at 60 to 75 mph picked up rocks and
        shattered the windows of a car in Louisville.  The strong
        winds blew down and partially destroyed two houses under
        construction just north of Thornton.  West winds gusted
        to 53 mph at Denver International Airport where the
        visibility was briefly reduced to 1/2 mile in blowing dust.
22-23 In 1936...heavy snowfall of 7.7 inches was measured in
        downtown Denver.  The heavy wet snowfall formed a thick
        coating of snow on trees and shrubs...but caused little
        damage.  North winds were sustained to 15 mph.
      In 1984...around a half foot of new snow fell across metro
        Denver...causing flight delays at Stapleton International
        Airport where snowfall totaled 6.0 inches and north winds
        gusted to 31 mph.  Up to a foot of snow fell in the
        foothills.  Icy roads produced numerous traffic accidents.
      In 2011...Strong bora winds developed along the Front Range
        following the passage of a storm system. Peak wind gusts
        included: 87 mph at the National Wind Technology Center;
        82 mph...6 miles northwest of Boulder; 72 mph at Front
        Range Airport in Broomfield; 71 mph at Longmont; and 64
        mph...4 miles west of Lakewood. At Denver International
        Airport...a peak wind gust of 48 mph from the west was
        observed on the 22nd.
      In 2013...A wet early spring snowstorm brought heavy snow to
        parts of the Front Range Foothills and Urban Corridor.  The
        heaviest snowfall occurred near the Front Range Foothills
        and Palmer Divide. Near blizzard conditions forced the
        closure of Interstate 70 east of Denver.  In the foothills...
        storm totals included: 14.5 inches near Conifer; 14 inches
        just southwest of Eldorado Springs and Intercanyon; 13
        inches near Indian Hills; 12.5 inches near Pinecliffe;
        11.5 inches near Golden; 11 inches near Jamestown and
        Roxborough; 10.5 inches near Brookvale and 10 inches at
        Genesee.  Across the Urban Corridor and Palmer Divide...
        storm totals included: 12.5 inches...8 miles southeast of
        Watkins; 10.5 inches in Boulder...Centennial and Northglenn;
        9.5 inches...just south of Aurora; 9 inches in Westminster;
        8 inches at Lafayette; 7.5 inches near Morrison; 7 inches
        in Arvada...Bennett...Brighton; 6 inches in Highlands Ranch...
        Longmont...Louisville and Thornton. Officially...11.6 inches
        of snow fell at DIA from the evening of the 22nd to the
        afternoon of the 23rd...which set a new two-day snowfall
        record in Denver for the date. In addition...a peak wind
        gust to 33 mph was observed from the east on the 22nd with
        a gust to 30 mph from the north on the 23rd.
22-24 In 1965...a vigorous cold front swept across metro Denver
        late on the afternoon of the 22nd with east-northeast
        winds gusting to 38 mph causing some blowing dust.
        Snowfall from the storm totaled 4.4 inches at Stapleton
        International Airport.  Temperatures on the 22nd dropped
        from a maximum of 63 degrees to 18 degrees in just 10 hours
        and dipped to 3 degrees below zero on the morning of the
        24th.  Maximum temperatures warmed to only 19 degrees on
        the 23rd and 18 degrees on the 24th.
