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

8-10  In 1979...from the 8th to the 10th...4.3 inches of snow
        fell at Stapleton International Airport where northwest
        winds gusted to 30 mph on the 8th. Most of the snowfall...
        2.3 inches...occurred on the 9th. High temperature of only
        35 degrees on the 9th equaled the record low maximum for
        the date.
9-10  In 1889...from the 9th to the 10th...heavy rainfall totaled
        2.15 inches in downtown Denver.  The cold rain was mixed
        with snow at times overnight.  Temperatures on the 10th
        ranged from a  high of 38 degrees to a low of 32 degrees
        with north winds sustained to 22 mph.
      In 2003...a late spring snowstorm hammered the mountains...
        eastern foothills...and urban corridor.  The heaviest
        snowfall occurred north of Interstate 70.  The heavy
        wet snow caused damage to trees throughout metro Denver
        and downed power lines.  About 40 thousand people along
        the urban corridor were without power.  Storm total
        snowfall amounts included:  11.5 inches in Louisville...
        8 inches in Boulder and Broomfield; 7 inches in
        Thornton...Broomfield...at Denver International Airport...
        and at the site of the former Stapleton International
        Airport; and 6 inches 4 miles east of Denver.  Snowfall
        ranged from 4 to 9 inches across extreme southern Weld
        County.  In the foothills...15 inches of snow fell near
        Jamestown...9 inches at Rollinsville and Rawah...with
        8 inches at Chief Hosa and atop Lookout Mountain.
        The snow was accompanied by thunder on the afternoon
        of the 9th at Denver International Airport where west
        winds gusted to 25 mph on the 9th and north winds gusted

        Moderate to heavy rain showers transitioned over to
        snow by early in the evening on the 9th. Heavy
        wet snow overnight caused many trees to break under the
        pressure of the sudden weight. Tree damage ranged from
        minor to significant...with old growth trees losing
        large limbs and new trees sustaining fatal damage. Power
        outages affected about 43350 Xcel Energy customers in
        metro Denver. The Intermountain Rural Electric
        Association also reported about 1000 power outages in

        Silverthorne due to multiple crashes.
10    In 1875...a windstorm sand-blasted the city from 10:00 AM
        until midnight.  Northwest winds sustained to 60 mph
        brought clouds of sand...which caused high damage to
        unfinished buildings.
      In 1912...a vigorous cold front produced strong north winds
        and rain.  North winds were sustained to 48 mph with gusts

        Lafayette.  A tower at Jefferson County Stadium in west
        metro Denver was blown over by the high winds.  No
        injuries were reported.  Southeast winds gusting to 48 mph

        dust.  The temperature climbed to a high of 86 degrees...
        equaling the record maximum for the date.
      In 2005...severe thunderstorms produced hail as large as

        metropolitan area. The hail ranged in size from 1 to 1 3/4
