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

26-27 In 1965...wind gusts to 38 mph were recorded in downtown
        Boulder...causing widespread minor damage.  A microburst wind
        gust to 41 mph was recorded at Stapleton International
27    In 1873...Pikes Peak was hidden from view by smoke from forest
        fires in the mountains to the southwest of the city.
      In 1927...the temperature cooled to a low of only 72 degrees...
        the all-time record high minimum for the month.
      In 1980...lightning injured 4 people on a baseball diamond in
        Broomfield.  The bolt seriously injured the pitcher while
        also striking (out) the batter...catcher and second baseman.
      In 1987...a microburst wind gust to 53 mph was recorded at
        Stapleton International Airport.
      In 1990...the temperature reached a high of 102 degrees...
        setting a new record maximum for the date.
      In 1993...thunderstorm winds gusted to 60 mph across parts of
        metro Denver.  A wind gust to 50 mph blew over a 30-foot
        canvas tent at an amusement park southeast of Denver.
        Fifteen people...mostly children...were injured.  Microburst
        wind gusts to 33 mph were recorded at Stapleton
        International Airport.
      In 2002...heavy rain...up to 3/4 inch...fell across sections of
        the Hayman burn area near Cheeseman Reservoir.  Several
        forest service roads were washed out and many culverts were
        plugged by debris.
      In 2004...heavy rain producing thunderstorms caused rock and
        mud slides across the Overland Fire burn area in Jamestown.
        An estimated 50 tons of sand...dirt...rock...and ash slid into
        town...filling a culvert under Main Street.  The slide covered
        150 to 225 feet of Main Street.  The flood was produced by
        half an inch of rain in 30 minutes.  A deluge of very heavy
        rainfall from nearly stationary thunderstorms caused flooding
        and flash flooding problems over parts of Jefferson and
        Douglas counties.  An automated rain gage in Golden measured
        3.60 inches of rainfall in one hour.  Numerous homes were
        flooded in Golden...including one that was 146 years old.
        The home was listed as a complete loss.  State Highway 93
        had to be closed from the Pine Ridge subdivision to the
        Golden Gate Canyon Road.   At the height of the storm...about
        4 feet of water covered State Highway 93 through Golden...
        forcing its temporary closure.  Several intersections were
        also flooded and impassable.  Rock and mud slides were
        reported in Golden Gate Canyon State Park.  At the Deer
        Creek Golf Course at Colorado 470 and Kipling...the greens
        were completely inundated by floodwaters.  Some backyards
        near the golf course were partially washed out.  In Douglas
        County...water up to a foot deep covered the roadways in
        Roxborough State Park.  The Waterton Canyon Road also had to
        be closed due to high water.
      In 2010...a severe thunderstorm produced hail up to 1 inch
        in diameter near Strasburg.  Hail up to 3/4 inch in diameter
        was reported in Aurora and Buckley Air Field.
