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

31-2  In 1980...the second major blizzard in 5 days buried much of
        eastern Colorado under 6 to 12 inches of snow.  Some drifts
        were up to 22 feet high.  Hundreds of travelers were
        stranded.  Over 3000 families were without power.
        Livestock losses were high.  Metro Denver escaped the
        main brunt of this storm.  At Stapleton International
        Airport...only 6.3 inches of snow fell over the 3-day period
        and north winds gusted to only 22 mph on the 1st.
31-3  In snowfall of 6.6 inches was measured at
        Stapleton International Airport where north winds gusted
        to 31 mph on the 31st.  The greatest accumulation of snow
        on the ground was 3 inches on the 1st.
31-4  In 1905...much rain and some snow occurred over the 5 days
        behind an apparent cold front.  Precipitation totaled 2.00
        inches.  There was a thunderstorm on the 3rd.  Snowfall
        totaled 3.0 inches on the 4th.  North winds were sustained
        to 34 mph on the 1st and 2nd and to 30 mph on the 3rd.
        High temperatures during the period ranged from the upper
        30`s to the lower 40`s.  Low temperatures were in the upper
        20`s and lower 30`s.
1-2   In 1963...strong winds buffeted metro Denver...while wind-
        whipped fires consumed grassland on the plains.  A child
        was injured by a wind blown falling tree in Castle Rock.
        Southwest winds gusted to 52 mph at Stapleton Airport...
        causing some blowing dust.  The worst fire storm burned
        over 25 thousand acres of grazing land in southern Weld
        County near Roggen northeast of Denver.
      In 1984...a snowstorm with near-blizzard conditions over
        eastern Colorado closed many roads...including I-70 and I-76
        east of Denver and I-25 between Denver and Colorado Springs.
        At Stapleton International Airport...snowfall totaled only
        2.5 inches...but north winds gusted to 45 mph on the 2nd.
      In 1999...moist upslope conditions allowed heavy snow to
        develop in the Front Range foothills where snowfall totals
        included:  10 inches at Aspen Park and Evergreen; 9 inches
        at Turkey Creek; 8 inches at Idaho Springs and Genesee;
        7 inches at Aspen Springs...Crow Hill...Intercanyon...and
        Lake George.  In metro Denver snowfall totals included:
        10 inches south of Sedalia; 8 inches in Littleton; 7 inches
        at Morrison; 6 inches at Highlands Ranch; and 4 to 5 inches
        in Northglenn...Parker and near Louisville.  Snowfall totaled
        4.7 inches at the site of the former Stapleton International
1-3   In 1945...snow fell across metro Denver for a total of 51
        consecutive hours.  While the storm was not accompanied by
        excessive snow...the long duration made the event a heavy
        snow producer.  Snowfall totaled 10.7 inches in downtown
        Denver with 9.5 inches recorded at Stapleton Airport.  North
        winds were sustained to 21 mph on the 1st; otherwise winds
        were not strong.  The air mass was very cold for April.
        The high temperatures of 26 on the 2nd and 17 on the 3rd
        were record low maximums for the dates.  The latter was also
        a record low maximum for the month.  Warm weather following
        the storm quickly melted the snow.
      In 1973...heavy snow fell at Stapleton International Airport
        where 8.7 inches were measured.  Snow began late on the 1st
        and continued through early morning on the 3rd.  Thunder
        accompanied the snow during the late morning and afternoon
        of the 2nd.  North winds gusted to 33 mph on the 2nd and
        37 mph on the 3rd.  Snow only accumulated to a depth of
        5 inches on the ground due to melting.
      In 1977 a foot of snow fell in Boulder and Broomfield.  The
        Denver-Boulder Turnpike was closed for an hour after
        numerous minor traffic accidents.  At Stapleton
        International Airport...snowfall totaled 4.7 inches and
        southeast winds gusted to 32 mph on the 2nd.  The greatest
        depth of snow on the ground was only 3 inches due to
2     In 1894...northwest winds were sustained to 42 mph with
        gusts to 48 mph.  The warm chinook winds warmed the
        temperature to a high of 70 degrees.
      In 1925...north winds were sustained to 40 mph with gusts
        to 42 mph.
      In 1957...a heavy snow storm dumped 17.3 inches of snow at
        Stapleton Airport.  Strong gusty north winds to 31 mph
        reduced visibilities to 1/8 mile at times and created
        blizzard conditions.  The 24-hour snowfall had been
        exceeded only twice in previous records...and the 24 hour
        precipitation of 2.05 inches was the third heaviest of
        previous record during April.
      In 1959...a cold front produced strong gusty winds across
        metro Denver.  North winds gusting to 50 and 60 mph caused
        some minor damage to power lines and signs and caused dust
        storms on the plains east of Denver.  A wind gust to 49 mph
        was recorded at Stapleton Airport.
      In 1966...northwest winds gusting to 52 mph produced blowing
        dust...which briefly reduced the visibility to 1 mile at
        Stapleton International Airport.
      In 1975...the all-time lowest recorded temperature in April...
        2 degrees below zero...occurred.  This is also the latest
        below zero reading for the season.
      In 1982...a strong windstorm struck all of metro Denver...
        causing minor damage.  Wind gusts to 127 mph were recorded
        at Rocky Flats south of Boulder...116 mph at Wondervu...100
        mph at Jefferson County Airport in Broomfield...and 56 mph at
        Stapleton International Airport.  The strong winds whipped
        up blowing dust...briefly reducing the visibility to 3/4 mile.
      In 1986...heavy thunderstorms produced wind gusts to about 70
        mph in Boulder.  A severe thunderstorm wind gust to 62 mph
        was recorded at Stapleton International Airport.  The strong
        winds kicked up thick clouds of blowing dust severely
        restricting surface visibility.
      In 1997...a Pacific storm left heavy snow in the foothills with
        lesser amounts across the city.  Snowfall totaled 12 inches
        near Blackhawk...11 inches at Golden Gate Canyon...10 inches
        at Conifer and Crowhill...9 inches at Evergreen...5 inches
        at Sedalia...and 4 inches at Castle Rock and Morrison.  Only
        2.1 inches of snow fell at the site of the former Stapleton
        International Airport.  Northwest winds gusted to 21 mph
        at Denver International Airport.
      In 1998...a major spring storm brought heavy snow to metro
        Denver and the foothills.  Snowfall totals ranged from
        12 to 22 inches in the foothills with 4 to 12 inches across
        metro Denver.  Snowfall totals included:  22.5 inches near
        Conifer; 13 inches in Coal Creek Canyon; 12 inches near
        Blackhawk...Eldora...and Genesee; 10 inches near Evergreen
        and Nederland; 9 inches in Lakewood; 8 inches in Broomfield
        and northwest Denver; and 7.0 inches at the site of the
        former Stapleton International Airport.  Northeast winds
        gusted to 31 mph at Denver International Airport.
      In 2002...snowfall was only a trace at the site of the former
        Stapleton International Airport.  This was the only snowfall
        of the month...ranking the month...along with previous months...
        the 2nd least snowiest on record.
2-3   In 1955...strong west to southwest winds raked metro Denver on
        both days.  Sustained winds as high as 37 mph with gusts to
        60 mph were recorded at Stapleton Airport where the
        visibility was reduced to 1/4 mile in blowing dust.
      In 1974...a heavy snowfall of 6.7 inches was accompanied by
        northeast wind gusts to 33 mph which produced some blowing
        snow across metro Denver.  Over eastern Colorado many
        highways and schools were closed due to near-blizzard
        conditions from the storm.
      In 1986...the worst snow storm of the season blasted metro
        Denver.  Heavy snow and high winds combined to close roads...
        schools...and airports.  Portions of all interstate highways
        out of Denver were closed at times.  The snow came after an
        exceptionally mild late winter and early spring;  trees and
        bushes had already bloomed and leafed out.  The snow and
        wind snapped many of these...causing power outages.  Total
        snowfall amounts in metro Denver ranged from 1 to 2 feet
        with 2 to 3 feet in the foothills.  Snowfall totaled 12.6
        inches at Stapleton International Airport where north winds
        gusting to 39 mph reduced the visibility to 1/8 mile in snow
        and blowing snow.  Most of the snow fell on the 3rd when
        temperatures hovered around 30 degrees for most of the day.
        The heavy snow halted traffic and closed businesses.  A 59-
        year-old man was found dead from exposure in northwest
        Denver.  The roof of a toy store in Northglenn collapsed.
        A 100 thousand square foot section of a greenhouse roof
        collapsed in Golden...destroying over a million dollars worth
        of plants.
      In 2000...a combination of strong instability and moist upslope
        winds allowed for a heavy...wet spring snowstorm to develop
        in and near the Front Range foothills.  The heaviest snow
        occurred in southern Jefferson County.  Storm totals
        included:  14 inches near Conifer...12 inches near Evergreen
        and on Floyd Hill; 11 inches near Blackhawk...Morrison...and
        Tiny Town; 10 inches at Aspen Springs and Eldora Ski Area;
        9 inches at Chief Hosa; and 8 inches at both Golden Gate
        Canyon and Rollinsville.  Only 2.1 inches of snow fell at
        the site of the former Stapleton International Airport.
        North winds gusted to 36 mph at Denver International
        Airport on the 2nd.
      In 2014...a storm system brought moderate to heavy snow to
        the Front Range Mountains...Foothills and Urban Corridor.
        Storm totals in the mountains and foothills included: 21.5
        inches...8 miles north of Blackhawk; 15.5 inches near
        Rollinsville; 15 inches at Aspen Springs; 14.5 inches near
        Ward; 12 inches...6 miles southwest of Evergreen; 11 inches at
        Cabin Creek and 12 miles south-southwest of Georgetown; 10
        inches at Winter Park; 8 inches near Conifer...Georgetown and
        Gross Reservoir; with 7.5 inches at Bailey and Intercanyon.
        In the Urban Corridor...storm totals included:  9.5 inches
        near Highlands Ranch...7 inches at Boulder...6 inches near
        Castle Rock...with 5.5 inches at Lakewood and near Morrison.
        At Denver International Airport...3.4 inches of snowfall was
2-4   In 1934...snowfall totaled 8.2 inches in downtown Denver
        from the afternoon of the 2nd through the early morning
        of the 4th.  Most of the snow...6.8 inches...fell on the 3rd.
        Rain changed to snow behind a strong cold front on the
        afternoon of the 2nd.  The cold front first appeared as a
        long-cigar shaped squall cloud to the north of the city.
        Strong north winds at sustained speeds of 33 mph with
        gusts to 43 mph produced much blowing dust and an abrupt
        fall in temperature...from a high of 68 on the 2nd to a
        low of 22 on the 3rd.
      In 1964...a major storm dumped 10.9 inches of heavy wet snow
        on Stapleton International Airport where northeast winds
        gusted to 35 mph.  Most of the snow...10.0 inches...fell on
        the 3rd.
2-5   In 1918...snowfall totaled 12.4 inches over downtown Denver.
        Most of the snow fell on the 3rd and 4th.  Temperatures
        were in the 20`s and 30`s.  Northwest winds were sustained
        to 24 mph on the 2nd.
