...This week in metro Denver weather history...

31-3  In 1979...total 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.
1-3   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
        melting.
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
        observed.
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.
3     In 1872...skies were cloudy and threatening until 11:30 AM
        when it commenced to rain and continued to rain until
        3:00 PM...when it turned into heavy snow with a very brisk
        north wind.  Snow continued all night.  Telegraph wires
        were downed between Denver and Cheyenne...and the night
        report could not be sent.  Precipitation (rain and melted
        snow) measured 0.82 inch.
      In 1887...north winds were sustained to 43 mph.
      In 1894...northwest winds were sustained to 41 mph with gusts
        to 50 mph.  The warm chinook winds on the 2nd became a
        bora as the temperature warmed to a high of only 52 degrees.
      In 1900...southeast winds were sustained to 52 mph with gusts
        as high as 61 mph.
      In 1945...the temperature warmed to only 17 degrees...the
        all-time record low maximum for the month.
      In 1968...a snow storm of unusual severity for so late in the
        season caused ground blizzard conditions with near zero
        visibility in snow at times and severe drifting of snow
        over portions of northeastern Colorado and metro Denver.
        Highways were blocked to the north of Denver and to
        Colorado Springs.  Rain at the start of the storm
        contributed to power and communications outages.  In
        metro Denver...snowfall totaled 7.0 inches at Stapleton
        International Airport where north winds gusted to 45 mph.
      In 1978...a tornado was sighted by a National Weather
        Service observer 3 miles north of Stapleton International
        Airport near the Rocky Mountain Arsenal.  Security police
        on the Arsenal called it a large dust devil...but four
        commercial airline pilots confirmed the phenomenon as a
        tornado or funnel cloud.
      In 1981...a snowstorm hit northeastern Colorado...dumping 6 to
        12 inches of snow in the foothills and 4 to 8 inches on the
        plains north of Denver.  Snowfall totaled only 2.0 inches at
        Stapleton International Airport where north winds gusted
        to 24 mph.
      In 1985...strong winds of 60 to 70 mph occurred in the
        foothills.  The driver of a car in Nederland was slightly
        injured when the wind toppled an utility pole onto his
        vehicle.  Northwest winds gusted to 53 mph at Stapleton
        International Airport where the visibility was briefly
        reduced to 2 miles in blowing dust.
      In 1989...a northwest wind gust to 51 mph was recorded at
        Stapleton International Airport.
      In 2011...high winds developing along the Front Range during
        the early morning hours.  Peak wind gusts included:  92 mph...
        7 miles northwest of Berthoud; 75 mph...2 miles west of
        Castle Rock; and 65 mph...2 miles west of Elbert.  West
        winds gusted to 49 mph at Denver International Airport.
3-5   In 1996...the foothills west of Denver received 6 to 8 inches
        of new snow.  Only 0.8 inch of snow fell at the site of
        the former Stapleton International Airport...along with
        some freezing drizzle on the 4th and 5th.  North-northeast
        winds gusted to 30 mph at Denver International Airport
        on the 3rd.
3-6   In 1898...snowfall totaled 8.7 inches in downtown Denver
        over the 4 days.  Northeast winds were sustained to
        48 mph with gusts as high as 60 mph on the 3rd.
      In 1983...a prolonged heavy snow storm blanketed the area
        along with very cold temperatures.  The greatest amounts
        of snow fell in the foothills where 24 to 42 inches
        were measured.  A foot of snow fell in Boulder.  Snow
        fell for 50 consecutive hours at Stapleton International
        Airport on the 3rd through the 5th with a total snowfall
        of 8.8 inches and a maximum accumulation on the ground of
        6 inches on the 5th.  In Denver...the mercury failed to rise
        above freezing for 3 consecutive days...on the 4th...5th...and
        6th...for the first time ever in April.  Five daily
        temperature records were set from the 4th through the 6th.
        Record low temperatures of 12 degrees occurred on the 5th
        with 7 degrees on the 6th.  Record low maximum temperatures
        of 25 degrees occurred on the 4th...27 degrees on the 5th...
        and 28 degrees on the 6th.
4     In 1888...southwest winds were sustained to 40 mph.
      In 1915...chinook winds from the northwest were sustained
        to 40 mph with gusts to 43 mph.  The winds warmed the
        temperature from a low of 44 degrees to a high of 67
        degrees.
      In 1935...light dust enveloped the city during the day
        on southwest winds sustained to 23 mph with gusts to
        27 mph.
      In 1985...north winds gusted to 53 mph at Stapleton
        International Airport where the visibility was briefly
        reduced to less than a mile by blowing dust and a snow
        shower.
      In 1987...microburst winds gusted to 51 mph at Stapleton
        International Airport.
      In 1997...heavy snow developed over western portions of metro
        Denver and along the Palmer Divide.  As a strong surface
        low pressure system intensified over the plains...moist
        upslope flow developed across metro Denver producing
        strong north winds at 20 to 40 mph and some blowing snow.
        Snowfall totaled 12 inches at Conifer with 4 to 7 inches
        at Crowhill...Evergreen...and Morrison.  Thunderstorm rain
        changed to snow across the city with 2.0 inches of snowfall
        measured at the site of the former Stapleton International
        Airport where precipitation (rain and melted snow) totaled
        0.70 inch.  North-northwest winds gusted to 43 mph at Denver
        International Airport.
4-5   In 1900...rain changed to heavy snow and totaled 7.8 inches in
        downtown Denver overnight.  A thunderstorm on the 4th
        produced hail.  Precipitation totaled 1.50 inches.
      In 1911...north to northwest winds were sustained to 42 mph
        on the 4th and to 41 mph on the 5th.
      In 2002...a whitish-colored haze engulfed metro Denver on both
        days.  The haze was the result of a huge wind storm that
        kicked up dust and sand from the Gobi Desert in Mongolia
        and China during the latter half of March.  Westerly winds
        aloft transported the dust cloud across the Pacific Ocean
        and over the western United States...depositing some of it
        on Colorado.
      In 2009...a blizzard developed over the Northeast Plains of
        Colorado.  Most of the Urban Corridor was spared from the
        blizzard...with the exception of eastern Adams and eastern
        Arapahoe Counties.  The combination of strong wind and
        heavy snow snapped 14 power lines along State Highway 36...
        near Strasburg.  In Arapahoe County...7 poles were snapped
        in Bennett.  Interstate 70 was closed in both directions
        east of Denver.  At Denver International Airport...a peak
        wind gust of 63 mph was observed from the north...breaking
        the previous record of 62 mph established in 1986.
        Officially...only 0.3 inches of snowfall was measured at
        Denver International Airport.
4-7   In 1909...post-frontal rain changed to heavy snow on the
        afternoon of the 4th and continued through mid-morning of
        the 7th.  Total snowfall was 18.7 inches...but most of the
        snow...14.0 inches...fell from 6:00 PM on the 4th to 6:00 PM
        on the 5th.  North to northeast winds were sustained to
        32 mph on the 4th and to 30 mph on the 7th.  Total
        precipitation from the storm was 1.78 inches.
5     In 1873...a heavy rain and hail shower in the afternoon
        changed to snow...and accumulated to 6 inches on the
        streets at 9:00 PM.  Precipitation (rain and melted snow)
        totaled 0.56 inch.
      In 1925...southeast winds were sustained to 46 mph with gusts
        to 50 mph.  This was the strongest wind of the month that
        year.
      In 1950...a well developed dust devil was observed 4 to 5
        miles south-southwest of Stapleton Airport for about 8
        minutes.
      In 1977...the earliest date of the last freeze of the season
        occurred when the temperature dipped to a low of 31 degrees.
      In 1988...a wind gust to 74 mph was recorded at Rollinsville.
        West winds gusted to 35 mph at Stapleton International
        Airport.
      In 1990...a heavy...wet snow fell in many areas in and along
        the Colorado Front Range.  Snowfall amounts of 4 to 7
        inches were common around the Boulder area with lesser
        amounts elsewhere.  Only 2.0 inches of snow fell at
        Stapleton International Airport where north winds gusted
        to 28 mph.  Icy roads contributed to numerous fender-benders
        and a 20-vehicle pileup near the junction of I-70 and I-25
        in the city.
      In 2000...high winds developed in the Front Range foothills...
        from about I-70 northward.  Peak wind gusts included:  83
        mph at the National Center for Atmospheric Research in
        Boulder...75 mph near Louisville...and 70 mph at the National
        Wind Technology Center...south of Boulder.  West winds
        gusted to 41 mph at Denver International Airport.
      In 2005...a surface low pressure center deepened over eastern
        Colorado and produced damaging high winds across metro
        Denver.  The strong wind gusts ranging from 50 to 70 mph
        damaged roofs and fences.  Cross-winds blew several empty
        semi-trailers on their sides along I-70 and I-76 east of
        Denver.  Peak north wind gusts included:  60 mph near
        Bennett and Keenesburg...59 mph near Brighton...and 53 mph
        at Denver International Airport.  Over the Palmer Divide
        south of Denver...the high winds combined with heavy snow
        to produce blizzard conditions.  Snowfall accumulations
        ranged from 3 to 8 inches over eastern Douglas and western
        Elbert counties.  Snowfall totals included:  8 inches at
        Sedalia...4 inches near Castle Rock...and 3.5 inches near
        Franktown.
5-6   In 1939...3.0 inches of snow fell in downtown Denver.  North
        winds were sustained to 34 mph on the 5th and to 26 mph on
        the 6th.  The strong winds caused considerable drifting of
        snow.  Several highways leading into the city were closed
        during the height of the storm due to poor visibility.
        Streets and highways became coated with ice in places.
        The temperature dipped to 11 degrees early on the 6th.
        This was the coldest reading of the month that year.
        Most vegetation was not far enough advanced to be injured
        by the cold temperatures...although a few buds froze on
        early shrubbery.
      In 1949...strong winds in Boulder caused limited minor damage.
        West-northwest winds were sustained to 24 mph with some
        higher gusts at Stapleton Airport.
5-7   In 1916...rain changed to snow behind a cold front on the
        5th and totaled 4.5 inches in the city.  A thunderstorm
        produced snow on the 6th.  North winds were sustained to
        35 mph with gusts to 38 mph on the 7th.
6     In 1904...northwest winds were sustained to 40 mph with gusts
        to 48 mph.
      In 1919...post-frontal rain changed to snow but totaled only
        0.1 inch.  However...north winds were sustained to 40 mph
        with gusts to 44 mph in the city.
      In 1954...a vigorous cold front produced northeast winds at 38
        mph with gusts as high as 50 mph.  The strong winds briefly
        reduced visibility to 1 1/2 miles in blowing dust at
        Stapleton Airport.
      In 1972...wind gusts to 68 mph were recorded at the National
        Bureau of Standards in Boulder.  Winds peaked to 54 mph in
        downtown Boulder.  Minor damage was reported.  Northwest
        winds gusted to 44 mph at Stapleton International Airport
        where the strong chinook winds warmed the temperature to
        a high of 80 degrees...equaling the record maximum for the
        date.
6-7   In 1872...rain changed to snow overnight.  Snow with high
        north winds continued all day on the 7th.  Precipitation
        (rain and melted snow) totaled 0.50 inch.  Due to problems
        on the lines...the morning weather report was not sent by
        telegraph until 3:10 PM and the midnight report was not
        sent at all.
       In 1957...heavy snowfall totaled 6.6 inches at Stapleton
        Airport where north winds gusted to 46 mph.  This was the
        second heavy snow event in less than 4 days.
      In 1969...winds gusting as high as 50 to 60 mph caused only
        light damage along the eastern foothills.  The strong
        winds contributed to the spread of a forest fire near
        Boulder.  Sustained winds of 25 mph with gusts to 53 mph
        were recorded in Boulder.  Southwest winds gusted to 38
        mph on the 6th and 44 mph on the 7th at Stapleton
        International Airport.
      In 1980...high winds howled along the foothills each day.  A
        wind gust to 72 mph was recorded in Lakewood.  The strong
        winds blew a camper top off a pickup truck in Denver.  At
        Stapleton International Airport...west winds gusted to 41
        mph on both days.
      In 1998...a spring storm brought a mix of snow and thunder
        to metro Denver...the foothills...and Palmer Divide.  Conifer
        and Elizabeth both measured 4 inches of new snow.  On the
        6th...only 0.1 inch of snow fell at the site of the former
        Stapleton International Airport where thunder was heard
        on both days.  Precipitation totaled 0.60 inch at Denver
        International Airport where west winds gusted to 43 mph
        on the 6th.
6-8   In 1973...a major spring snow storm dumped 11.6 inches of
        snowfall over metro Denver.  North wind gusts of 30 to 35
        mph produced some blowing snow.  Most of the heavy wet snow...
        10.1 inches...fell on the 7th when temperatures remained
        in the 20`s.  Snow accumulated on the ground to a maximum
        depth of 9 inches.  Low temperature of 5 degrees on the
        8th was a new record minimum for the date and the lowest
        for so late in the season.
7     In 1906...north winds were sustained to 48 mph in the city.
      In 1958...strong south winds blew most of the day across metro
