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

11-14 In 1999...damage from several hailstorms...from the 11th to
        the 14th...in and near metro Denver totaled 35 million
        dollars.  About 17.5 million dollars was from automobile
        claims with another 17.5 million in homeowner claims. The
        areas hardest hit by the storms included Castle Rock...
        Commerce City...Evergreen...and Golden.
12-17 In 2000...two large wildfires developed in the Front Range
        foothills on the 12th and continued through the 17th...as
        careless campers and very dry conditions proved to be a
        dangerous combination.  Strong winds gusting in excess of
        60 mph on the 13th fanned the flames...spreading both
        wildfires out of control.  Winds gusted to 78 mph atop
        Niwot Ridge near the Continental Divide west of Boulder.
        The Hi Meadows Wildfire...about 35 miles southwest of Denver...
        consumed nearly 11 thousand acres and 80 structures...mostly
        high priced homes.  The Bobcat Wildfire...located about 12
        miles southwest of Fort Collins...consumed nearly 11
        thousand acres and 22 structures.  Late on the 16th...a
        strong cold front moved south over the Great Plains into
        northeastern Colorado.  Low level upslope developed in
        the wake of the front...producing 2 to 4 inches of snowfall
        overnight at elevations above 8 thousand feet.
        Firefighters were able to contain both fires shortly
        thereafter.
13-14 In 2006...the high temperature of 99 degrees on the 13th
        equaled the record maximum temperature for the date first
        set in 1994.  The high temperature of 102 degrees on the
        14th was a new record maximum temperature for the date.
14    In 1877...an evening thunderstorm produced lightning which
        struck several houses and killed a cow in the bottom land
        of the South Platte River
      In 1886...hail as large as 3/4 inch in diameter fell in the
        city.  Precipitation was only 0.10 inch.
      In 1887...south winds were sustained to 41 mph.
      In 1900...a thunderstorm produced northwest winds to 51 mph
        with gusts to 61 mph...but only a trace of rain.

      In 1960...one workman was killed and 4 others injured in
        Lakewood when a partly built apartment building collapsed
        in strong winds.  Microburst wind gusts to 54 mph caused
        some blowing dust at Stapleton Airport.
      In 1967...tornadoes touched down briefly 3 miles west of
        Franktown and 4 miles northeast of Parker.  No damage was
        reported.  Numerous funnel clouds were reported over south
        metro Denver...one 5 miles south of Denver...one 2 to 3 miles
        north of Castle Rock...and two near Littleton.
      In 1968...a microburst wind gust to 52 mph was recorded at
        Stapleton International Airport.
      In 1972...1 3/4 inch hail was reported in Wheat Ridge.
      In 1976...high winds...unusually strong for this late in the
        season...raked metro Denver.  Wind gusts estimated to 100
        mph tore 24 boats from their moorings and damaged a total
        of 47 boats at Boulder Reservoir.  Wind gusts to 82 mph
        were recorded in Boulder.  The strong winds toppled the
        wind mast at a radio station in Boulder.  An automobile
        was smashed by a fallen tree in Boulder.  Other damage in
        Boulder was minor...but power outages occurred when tree
        limbs fell on  power lines.  At Jefferson County Airport
        near Broomfield...wind gusts to 78 mph were recorded with
        87 mph gusts clocked at Rocky Flats Nuclear plant south of
        Boulder.  Wind gusts to 66 mph were observed in Littleton...

        foothills.
      In 1982...the worst hailstorm in 17 years struck Commerce
        City.  The storm left 4 to 8 inches of hail on the ground.
        A few of the stones were as large as golf balls.  Many
        vehicles were dented...and some windshields were shattered.
        Roofs of homes were damaged.   Total damage was estimated
        at over one million dollars.  Hail to 1 inch in diameter
        also fell in Littleton.  Only 1/4 inch hail was measured
        at Stapleton International Airport.
      In 1988...lightning ripped a small hole in the roof of a home

        Lightning sparked two small fires at separate residences
        near the Hiwan Country Club in Evergreen.
      In 2004...lightning sparked two small fires near Jamestown.
        One was in Geer Canyon and the other 7.5 miles up Sunshine
        Canyon.  Both were quickly contained and caused no damage
        to structures in the area.
      In 2009...a complex of severe thunderstorm produced large hail
        damaging thunderstorm and funnel clouds across parts of the
        Urban Corridor.  The line formed along a boundary over the
        western suburbs of Denver then moved east. The boundary
        produced at least one well defined funnel cloud that could
        be observed by stadium full of baseball fans at Coors
        Field.  Large hail...up to 1 3/4 inches in diameter...was
        reported in Arvada...Broomfield...Denver...Federal Heights and
        Northglenn.  In addition...the storm produced peak wind gusts
