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

10-14 In rain on the 10th changed to snow on
        the 11th and continued through the 14th.  Snowfall totaled
        8.5 inches from precipitation of 1.28 inches.  North winds
        were sustained to 26 mph with gusts to 29 mph on the 13th.
12-13 In rain changed to heavy snow...which
        totaled 7.0 inches in downtown Denver.  This was the
        second snow in 3 days.  North winds were sustained to
        29 mph with gusts to 31 mph on the 12th.
      In 1993...heavy snow occurred in the foothills northwest of
        Denver with 21 inches recorded at the Eldora ski area.
        Only 1.9 inches of snow fell at Stapleton International
        Airport where northeast winds gusted to 32 mph on the 13th.
        Most of the precipitation from the storm fell as rain across
        the city with 0.62 inch of precipitation measured at
        Stapleton International Airport.
12-14 In 1933...heavy snowfall of 5.6 inches occurred in downtown
        Denver on the 12th and 13th behind a vigorous cold front...
        which presented an awe-inspiring spectacle as it approached
        the station during the late afternoon of the 12th.  Brilliant
        white wind-torn cumulus clouds were sandwiched by a brownish-
        tan dust cloud at the surface and dark blue cumulus clouds
        above.  The dust cloud storm rapidly enveloped the station
        with northeast winds sustained to 38 mph and gusts to 44 mph
        producing much blowing dust...which was accompanied by rapidly
        falling temperatures and rising pressure.  Moist snowfall
        started in about an hour and continued to midday on the 13th.
        Record low temperatures of 17 and 15 degrees occurred on the
        13th and 14th respectively.  The high temperature of only 27
        degrees on the 13th was a record low maximum for the date.
12-15 In 1927...snowfall totaled 8.5 inches in downtown Denver.
        Most of the snow fell on the 14th.  Northwest winds
        were sustained to 27 mph during the storm.
13    In 1873...heavy snow started with fresh and brisk north
        winds around 9:00 AM...and continued heavy until 2:00 PM
        and lightly until 7:00 PM.  Temperatures were below
        freezing for most of the day...but the snow melted
        almost as fast as it fell.  Precipitation from the
        melted snow totaled 0.70 inches.  This would be
        around 7.0 inches of estimated snowfall.
      In 1912...a severe wind and dust storm struck the city.
        West winds were sustained to 40 mph with gusts to 42
      In 1967...a late season snow storm affected areas along the
        eastern foothills from Denver south.  Snowfall between 2
        and 3 feet closed I-25 between Denver and Colorado Springs.
        In Denver...snowfall was only 3.6 inches...but precipitation
        from the storm totaled 3.25 inches...the greatest 24-hour
        precipitation ever recorded during the month of April.
        North winds gusted to 35 mph at Stapleton International
        Airport.  Temperatures across the city were in the 30`s
        most of the day.
      In 1974...a major spring snow storm dumped 8.5 inches of heavy
        wet snow at Stapleton International Airport where north
        wind gusts to 38 mph produced some blowing snow.  The storm
        caused minor damage to public utilities.
      In 1986...strong winds howled across metro Denver.  Boulder
        reported a peak gust of 79 mph.  Wind gusts of 55 to 60 mph
        were common across all of metro Denver.  There were power
        outages.  The wind toppled a brick wall under construction
        in Arvada...and also damaged luxury sky boxes under
        construction atop Mile High Stadium in Denver.  Road signs
        in Arvada were damaged.  West winds gusted to 56 mph at
        Stapleton International Airport.
      In 2014...a storm system brought heavy snow to areas in and near
        the Front Range Foothills.  Storm totals included: 13 inches
        near Conifer; 12.5 inches near Ward; 11.5 inches near
        Nederland; 10 inches near Allenspark...Golden and Gold Hill;
        with 8.5 inches at Roxborough State Park.
13-14 In 1968...high winds struck Boulder.  Sustained winds of 50
        mph with gusts as high as 102 mph were recorded at the
        National Center for Atmospheric Research...while in downtown
        Boulder winds peaked to 73 mph.  The winds damaged
        a building under construction and some homes in
        south Boulder.  Northwest winds gusted to 35 mph at
        Stapleton International Airport on the 13th.
      In 1996...a potent spring storm strengthened just east of
        Denver.  Blizzard conditions developed over eastern Adams
        and eastern Arapahoe counties.  Strong northerly winds
        ranging from 25 to 50 mph...cold temperatures...and heavy
        snowfall combined to create very hazardous conditions.
        The strong winds whipped snow in drifts 3 to 4 feet high.
        High winds and heavy wet snow downed power lines and
        caused traffic accidents.  Some roads were closed.
        Snowfall totaled 15 inches at Strasburg...while only 2.1
        inches of snow fell at the site of the former Stapleton
        International Airport.  North winds gusted to 40 mph at
        Denver International Airport on the 13th.
      In 2011...a potent spring snowstorm brought heavy snow to
        Front Range mountains and foothills.  Storm totals
        included:  16.5 inches near Blackhawk; 16 inches at
        Nederland; 15.5 inches at Coal Creek Canyon and 5 miles
        northeast of Ward; 15 inches at Allenspark; 12.5 inches...
        5 miles northwest of Idaho Springs; 12 inches at Echo
        Mountain Ski Area; and 10.5 inches near Georgetown.
13-15 In 1945...heavy snowfall totaled 9.8 inches in downtown
        Denver.  Most of the snow...4.8 inches...fell on the 14th.
        Snow fell for a total of 53 consecutive hours.  This
        was the second big snow in less than 2 weeks.  The air
        mass was very cold for April.  High temperatures of 21
        degrees on the 14th and 32 degrees on the 15th were
        record low maximums for the those dates.
13-17 In 2001...a huge dust storm over southern and inner Mongolia
        during April 3rd through the 6th lifted desert dust into
        the jet stream.  This dust cloud moved over metro Denver
        on the 13th and persisted through the 17th.  The cloud
        created widespread the sky a milkish cast
        due to the scattering of incoming solar radiation.
