... Today in Metro Denver weather history...

2-4 in 1963... heavy wet snow was accompanied by strong gusty winds
        across Metro Denver. Snowfall totaled 11.6 inches at
        Stapleton Airport where north winds gusting to 44 mph
        caused much blowing and drifting snow. Hazardous driving
        conditions resulted in many traffic accidents.
      In 1976... snowfall totaled 8.0 inches at Stapleton
        International Airport where... on the 4th... northeast winds
        gusted to 31 mph reducing the visibility to as low as 1/4
        mile. Maximum snow depth on the ground was 7 inches. Nine
        inches of snow were measured in Boulder.
3-4 in 1932... a dust storm occurred on the 3rd during the late
        afternoon. North winds gusting as high as 38 mph behind
        a cold front kicked up much blowing dust. Light snow
        developed during the evening and continued through the
        early morning of the 4th. Snowfall totaled 2.7 inches.
      In 1934... strong winds raked Boulder. A wind gust to 62 mph
        was recorded at Valmont just east of Boulder. The strong
        winds caused hundreds of dollars of damage in Boulder.
      In 1981... the most vigorous snow storm of the season struck
        the state... closing many schools and most highways
        connecting Denver... Colorado Springs... and Limon. North
        winds gusting to 43 mph whipped nearly 10 inches of snow
        in Denver into 3-foot drifts and snarled traffic on the
        morning of the the 4th. Snowfall totaled 9.8 inches at
        Stapleton International Airport.
      In 1989... a storm dumped 2 to 6 inches of snow across Metro
        Denver. The snow caused 2-hour air traffic delays at
        Stapleton International Airport where 3.0 inches of snow
        fell and north winds gusted to 23 mph on the 3rd. There
        were many traffic accidents across Metro Denver. I-70 was
        closed east of Denver for a time on the 3rd.
      In 1991... high winds raked the eastern foothills. Wind gusts
        of 60 to 90 mph were common with 119 mph recorded at
        Wondervu southwest of Boulder... 106 mph on shanahan ridge
        and 92 mph at Table Mesa... both in southwest Boulder.
        Several trees were uprooted and traffic signs and lights
        blown over. Flying debris caused damage to homes...
        buildings... and cars. In Boulder... a stop sign was blown
        onto a car. There were no reports of injuries. Southwest
        winds gusting as high as 48 mph briefly reduced the
        prevailing visibility to as low as 1/16th mile in blowing
        dust at Stapleton International Airport on the 4th.
3-5 in 1961... snowfall totaled 8.3 inches at Stapleton Airport
        over the 3-day period with most of the snow... 4.4 inches...
        falling on the 3rd. Winds were generally light gusting to

        center for atmospheric research in Boulder. A wind gust to
        83 mph was measured at the National Bureau of standards.
        In downtown Boulder... sustained winds reached 35 mph with
        gusts as high as 57 mph. No significant damage was
        reported. West winds gusted to only 28 mph at Stapleton
        International Airport.
      In 1982... brief heavy snow accompanied by a few thunderstorms
        struck Metro Denver. Lightning struck a house in Arvada
        setting it afire. The thunderstorm produced 5 inches of
        snowfall in a 2-hour period in Wheat Ridge. The snow
        made roads very icy and slick causing a 59-car pile-up on
        I-70 in north Denver. Snowfall with thunder totaled only
        1.3 inches at Stapleton International Airport.
      In 1997... a fast moving Pacific storm produced heavy snow

        International Airport. North northeast winds gusted to
        28 mph at Denver International Airport.

        totaled 6.2 inches. Temperatures plunged from a high
        of 58 degrees on the 4th to a low of only 22 degrees
        by midnight... which was also the high reading on the
        5th.
      In 1983... a slow moving moisture laden storm produced heavy
        snow and rain. Two to three feet of snow fell in the
        foothills at Wondervu and Nederland. The southern portion
        of Metro Denver was buried with 26 inches of snow in
        southeast Aurora... 25 inches at Franktown... and 19 inches
        at Littleton. Snowfall totaled 18.7 inches at Stapleton
        International Airport with most of the snow... 18.0 inches...
        falling on the 5th. Brighton received only 11 inches
        of new snow. Boulder was drenched by rain and received
        no snow. Precipitation from the storm totaled 3.06
        inches at Stapleton International Airport where north
        winds gusted to 28 mph. The heavy wet snow snapped many
        tree limbs... which fell on power and phone lines causing
        many outages. Numerous highways were closed. Two thousand
        travelers were stranded at Stapleton International
        Airport where only one runway was open for a time. Many
        flights were canceled. One home in Denver was severely
        damaged when its roof collapsed under the weight of the
        heavy snow. The 2.68 inches of precipitation on the 5th
        was the greatest calendar day precipitation ever recorded
        in the city during March. The 2.79 inches of precipitation
        on the 4th and 5th was the greatest 24 hour precipitation
        ever measured during March.
