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

1-30  In 2012...it was the hottest June in Denver since weather
        records began back in 1872. The average temperature for
        the month was 75.0 degrees which was 7.6 degrees above
        normal.  There were a total of seventeen 90 degree days in
        the month of June. The highlight of record setting month
        was a stretch of five consecutive 100 degree days from the
        22nd to the 26th. This was only the third time in Denver
        weather history in which this happened. Two of the high
        temperatures during the stretch peaked at 105 degrees...
        which set the all time record for the month of June and
        tied the all time maximum temperature for Denver.
11-14 In 1999...damage from several hailstorms 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 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
        conditions 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    In 1956...a microburst caused a brief wind gust to 59 mph at
        Stapleton Airport.
      In 1957...an unconfirmed tornado appeared to touch the ground
        in the vicinity of Franktown.  No damage was reported from
        the twister.
      In 1968...a violent gust of wind...possibly associated with a
        thunderstorm...caused 75 hundred dollars damage in Boulder.
      In 1973...hail...1/2 to 3/4 inch in diameter...fell over
        Lakewood.  Flash flooding occurred in west Denver from the
        same storm.
      In 1974...a thunderstorm wind gust to 64 mph was recorded at
        Stapleton International Airport.
      In 1977...hail the size of table tennis balls...1 1/2 inches in
        diameter...was reported in Boulder.
      In 1981...large hail to golf ball size fell in Denver...
        Northglenn...and Brighton.  Hail as large as baseballs was
        reported in Federal Heights.
      In 1984...one of the worst hailstorms ever experienced in metro
        Denver struck the northwestern suburbs of Arvada...Wheat
        Ridge...and Lakewood...but large hail also fell in Golden...
        southeast Denver...and Aurora.  Homes and other buildings
        sustained around 200 million dollars in damage.  Thousands
        of cars were battered by giant hailstones...and total damage
        to vehicles was estimated at 150 million dollars.  In some
        areas...golf ball size hail fell continuously for 30 to 40
        minutes.  Some places were pelted with a few stones as
        large as grapefruits!  Roofs on thousands of structures
        were severely damaged.  Uncounted car windshields were
        broken; two-thirds of Arvada`s police cars were rendered
        inoperable.  Torrential rains...with as much as 4.75 inches
        in Lakewood clogged drains and caused widespread damage
        from flooding.  In some places hail was washed into drifts
        several feet deep.  About 20 people were injured by the
        giant hailstones.  One couple was hospitalized.  A woman
        drowned when she was trapped under a trailer by high water.
        Only pea size hail fell at Stapleton International Airport.
      In 1988...2 inch hail fell in Parker.  Soft hail 1 inch in
        diameter fell at the mouth of Turkey Creek Canyon 5 miles
        southeast of Morrison.  Hail between 1 inch and 1 3/4
        inches fell at both Bennett and Strasburg.  A tornado
        touched down briefly at Strasburg.  A brief funnel cloud
        was sighted by National Weather Service observers 15 miles
        southwest of Stapleton International Airport.
      In 1991...a Boulder man was injured when struck by lightning
        while in a tent.  He received only minor burns.
      In 1997...lightning struck a home in Denver.  The extent of
        the damage was unknown.  A home in Littleton was also
        struck.  The house caught fire...but the extent of the
        damage was not known.
      In 1998...a strong mountain wave produced a brief period of
        high winds along the Front Range.  A small building atop
        Squaw Pass west of Denver was blown down.  Tree limbs
        were downed across metro Denver.  Peak wind gusts
        included:  80 mph on Squaw Pass...69 mph at Jefferson
        County Airport near Broomfield...and 60 mph in Westminster
        and at the National Center for Atmospheric Research in
        Boulder.  West-northwest winds gusted to 51 mph at Denver
        International Airport.
      In 2001...high winds developed briefly in Boulder County.
        A peak wind gust to 76 mph was recorded at the National
        Center for Atmospheric Research atop the mesa in Boulder.
        A wind gust to 72 mph was recorded at Southern Hills Middle
        School in Boulder.  Lightning started a small fire...which
        damaged the roof of a house in Greenwood Village.
      In 2009...severe thunderstorms produced hail up to one inch
        in diameter near Arvada and Byers...as well as 7 miles
        north-northwest of Front Range Airport near Watkins.
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.
