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

7-9   In 1979...rain...at times with thunder on the 7th...fell almost
        continuously through the morning of the 9th.  Rainfall
        totaled 2.28 inches at Stapleton International Airport
        over the 3 days.  High temperature of only 49 degrees on
        the 8th was a record low maximum for the date.
9     In 1900...an apparent cold front produced north winds to
        42 mph with gusts to 47 mph.
      In 1923...heavy rainfall totaled 2.18 inches in downtown
        Denver...where northwest winds were sustained to 27 mph.
        Heavy rain also fell in Boulder...causing flooding on
        Boulder and South Boulder creeks.
      In 1939...post-frontal sustained northwest winds to 35 mph
        produced some blowing dust...which reduced the visibility
        to one mile at times during the afternoon.  Dusty
        conditions prevailed into the early evening.  The airport
        station reported a maximum wind of 56 mph.  A few minor
        injuries and some damage resulted.  A few trees were
        uprooted...some fruit was blown from trees...and a section
        of power lines was blown down.
      In 1959...dry thunderstorm winds...estimated to near 70 mph...
        toppled a 40-foot-high poplar tree...which was 4 to 5 inches
        in diameter...near Cherry Creek Dam.  The Colorado State
        Patrol reported a possible tornado 1 mile south of the dam.
      In 1960...strong gusty winds tore the roofs from 2 patios in
        Aurora.  One of the roofs was blown over a house and landed
        on a car damaging its top.  A house trailer was also
        overturned.  Other minor damage was reported to roofs...
        windows...and trees in Aurora.  A thunderstorm wind gust
        to 43 mph was recorded at Stapleton Airport.
      In 1963...golf ball size hail fell at Cherry Creek Reservoir.
      In 1967...a small tornado damaged trees and a dwelling in
        south Denver.  The storm touched down at the intersection
        of 1st Avenue and Harrison Street and moved northeast to
        the intersection of 3rd Avenue and Albion Street.
        Damage included 3 small roofs removed...15-20 large trees
        uprooted...one car overturned and thrown against a house...
        plus other minor damage.  A funnel cloud reported at the
        same time 10 miles north of Denver possibly touched ground.
        Later...funnel clouds were reported 12 miles south-southeast
        of Stapleton International Airport...10 miles southwest...and
        5 miles north.  A tornado was sighted 3 1/2 miles east of
        Stapleton International Airport by Weather Bureau personnel
        for a duration of 5 minutes.  Heavy rain and some hail fell
        over much of the area.
      In 1974...the start of the shortest seasonal snow free period
        on record...94 days...occurred with the last snow of the
        season...a trace...on the 8th.  The first snow of the next
        season occurred on September 11th when a trace of snow
        fell at Stapleton International Airport.  A funnel cloud
        was observed just east of Aurora and a small funnel was
        sighted just northeast of Stapleton International Airport.
      In 1985...a thunderstorm wind gust to 62 mph was reported at
        Golden Gate Canyon in the foothills west of Denver.
      In 1986...a thunderstorm...which dumped heavy rain and caused
        some street flooding across north metro Denver...produced
        a small tornado 5 miles east of Brighton.  No damage was
        reported.
      In 1987...strong thunderstorm wind gusts in Conifer destroyed
        a porch on a house; the wind gust apparently picked up the
        porch and dropped it on a man...killing him.  The wind also
        damaged the roof of the house and a nearby barn.  The same
        thunderstorm spawned a tornado...which touched down briefly
        just south of Lakewood.  No damage was reported.  Up to 3
        inches of rain fell in a short time 8 miles southwest of
        Littleton.  A few businesses in Englewood suffered minor
        water damage.  A tornado was sighted between Watkins and
        Bennett.  It was on the ground for 15 minutes.  A weak
        tornado also touched down 4 miles southwest of Castle Rock.
        The twister tossed an aluminum shed into the air and
        carried it about 100 feet.  A funnel cloud was sighted
        15 miles east-northeast of Stapleton International Airport.
      In 1988...golf ball size hail fell in Conifer along with 1.30
        inches of rain.  Three miles north of Louisville...1.10
        inches of rain fell in 20 minutes.  Ping pong ball size
        hail was measured in Arvada.
      In 1990...3/4 inch hail fell in Castle Rock.
      In 1991...hail two inches in diameter fell near Evergreen.
        Hail to 1 inch diameter fell in Lakewood where a funnel
        cloud was also sighted.  One inch diameter hail was also
        reported in Aurora.
      In 2002...high temperatures...low relative humidities...and
        strong gusty winds allowed the Hayman Wildfire...located
        in the foothills to the southwest of Denver...to become
        the largest wildfire in the state`s history.  Although
        the fire was initially started by a U.S. Forest Service
        employee...the ongoing drought and dry conditions allowed
        the fire to spread rapidly out of control.  The wildfire
        consumed nearly 138 thousand acres of forest land and 133
        homes before it could be contained and finally extinguished
        on June 30th.  About 1800 households had to be evacuated
        during the blaze.  Southwest winds aloft swept the smoke
        plume directly over metro Denver...creating poor air quality
        and blocking the sun.  Much of metro Denver choked on smoke
        with the southern suburbs receiving the most.  Smoke and
        ash restricted surface visibilities to a mile or less at
        times in the Denver and Castle Rock areas and to 2 miles
        at Denver International Airport.
      In 2003...thunderstorm winds gusted to 51 mph at Denver
        International Airport.  The storm produced only a trace
        of rain.
      In 2004...severe thunderstorms produced large hail across
        portions of metro Denver for the second day in a row.
        The most extensive damage occurred across southern sections
        of metro Denver in Aurora...Lakewood...Littleton...and south
        Denver.  The combined damage to homes and vehicles...not
        including commercial buildings...was estimated at 146.5
        million dollars...making the event the 4th costliest
        insurance disaster in the state`s history.  Hail as large
        as 2 1/4 inches in diameter fell near southern Aurora with
        hail to 1 3/4 inches in the City of Denver and in Lakewood.
        Hail to 1 1/2 inches fell near Morrison with 1 inch hail
        measured in Thornton...near Buckley Air Force Base...and
        near Roggen.  Hail to 3/4 inch diameter fell in Littleton
        and near Conifer.  A small tornado touched down near
        Bennett...but did no damage.
9-10  In 1864...from the 9th to the 10th...high water from melting
        snow combined with heavy rains over the upper reaches of
        the South Platte River forced the river over its banks and
        caused flooding of low lying areas along the river in the
        city.  The amount of rainfall in the mountains and in the
        city is unknown.
