...This week in metro Denver weather history...

7-25  In 1934...a streak of 15 consecutive days of 90 degrees
        ranked 5th on the list of hot streaks.  The record of
        24 consecutive days was established in the summer of
13-5  In 2008...a streak of 24 consecutive days of 90 degrees
        shattered the previous record of 18 consecutive days
        established in 1901 and 1874. new single
        day record high temperatures were set in the month of July.
        In August however...a record of 104 degrees was set on the
        1st...and another record of 103 degrees was set on the 2nd.
        In addition...a record low min of 70 degrees was set on
        August 2nd.
15-16 In 2006...a brief mid July hot spell resulted in two 100
        plus degree high temperatures and two daily maximum
        temperature records.  The high temperature climbed to
        101 degrees on the 15th and 103 degrees on the 16th
        at Denver International Airport.
16    In 1911...thunderstorm winds were sustained to 44 mph from the
      In 1959...a thunderstorm produced 3/8 inch diameter hail and
        a wind gust to 60 mph at Stapleton Airport.
      In 1972...two tornadoes were sighted by the public to the
        southeast of Aurora.  No damage was reported.
      In 1978...a thunderstorm wind gust to 52 mph was recorded at
        Stapleton International Airport.
      In 1980...a severe thunderstorm ripped through metro Denver...
        producing torrential rain...large hail...and strong winds.  In
        Aurora...winds gusted to 65 mph with hail up to 1 1/2 inches
        in diameter and half an inch of rain in just 10 minutes.
        Stapleton International Airport was closed for an hour.
        Large hail also fell in southeast Denver...Lakewood...Parker...
        and Castle Rock.  Up to 1 1/2 inches of rain fell in just 40
        minutes.  Heavy rains in Wheat Ridge flooded a shopping
        center...breaking windows and doors...while causing 100
        thousand dollars in damage.  Some roofs and windows were
        damaged throughout metro Denver.  At Stapleton International
        Airport where west winds gusted to 49 mph...1/4 inch hail
        and 0.77 inch of rain fell.
      In 1983...severe thunderstorms dumped large hail over much of
        metro Denver.  Hail to 3/4 inch in diameter fell in Littleton
        and Northglenn...with 3/4 to 1 inch hail in Arvada...1 to 1 1/2
        inch hail in extreme northwest Denver...1 3/4 inch hail in
        Lakewood...1 1/2 inch hail in south Arvada and just northeast
        of Aurora...and 1 5/8 inch hail on Green Mountain.
      In 1994...spotters reported a brief tornado touchdown in an
        open field just north of Fort Lupton.  No damage or injuries
        were reported.
      In 2000...very moist and unstable weather conditions...along
        with low level upslope flow during the late afternoon and
        evening...combined to produce heavy thunderstorm rainfall...
        which caused urban and small stream flooding across metro
        Denver.  Rainfall amounts generally ranged from 1 to 3 inches
        with the heaviest rainfall occurring during the evening hours.
        Two miles east of White Ranch in northern Jefferson County...
        an automated rain gage measured 3.86 inches of rain.  Since
        the rain fell in a relatively open flood damage
        was reported. Greenwood Village near the
        intersection of Peoria and Belleview...the streets were
        closed for several hours with as much as 2 feet of standing
        water covering the roadways.  Two campers near Mt. Evans
        were injured by lightning and stranded overnight by the
        inclement weather.  Both received minor injuries.
      In 2003...the high temperature of 101 degrees was a record
        maximum temperature for the date.
      In 2004...locally heavy rainfall of unknown amount caused
        parts of the Virginia Canyon Road near Idaho Springs to
        wash out.  The road had to be closed temporarily.
      In 2005...the temperature climbed to a high of 102 degrees
        at Denver International Airport.  This was a new record
        maximum temperature for the date at the time.
16-18 In extended hot spell resulted in 3 temperature
        records being set.  The maximum temperature reached 98
        degrees on each of the days...setting records on the 16th
        and 18th.  The low temperature of 71 degrees on the 17th
        was a record high minimum for the date.  The high
        temperature reached 100 degrees on the 17th at the site
        of the former Stapleton International Airport.
17    In 1872...the U.S. Army Signal Service weather observer
        recorded snowfall during the early morning hours in the
        hand written daily weather journal:  "Rain commenced at
        1:30 A.M. changing about 3 A.M. to snow & in about half
        an hour to rain again; it continued until 6 A.M."  This
        is the only recorded occurrence of snowfall in Denver in
        July...but this report is not included in the "official"
        station snowfall records...which did not begin in Denver
        until January 1...1882.  The low temperature on this
        morning was 45 degrees...which is sufficiently cold for
        the occurrence of light stratiform snowfall.
      In 1918...a thunderstorm produced hail to an inch in depth
        on the ground.  The stones varied in size from a small
        cherry stone to nearly 1/2 inch in diameter.  Not much
        permanent damage was done to crops.  Precipitation
        totaled 0.40 inch...and northeast winds were sustained
        to 25 mph with gusts to 28 mph.
      In 1971...the temperature reached a high of 101 degrees at
        Stapleton International Airport.
      In 1983...3/4 inch diameter hail fell at Lafayette...while
        golf ball size hail pelted Brighton and Northglenn where
        funnel clouds were also sighted.
      In 1986...1 1/2 inches of rain fell in an hour and 15 minutes
        in southeastern Aurora.  Thunderstorm rainfall totaled
        0.89 inches at Stapleton International Airport.
      In 1987...a small tornado was sighted near the
        vicinity of Front Range Airport.
      In 1997...lightning ignited an oil well tank holding 10
        thousand gallons of oil...16 miles northwest of Bennett.
        About 200 acres of grassland burned before the fire could
        be extinguished.  A dry microburst produced a wind gust to
        52 mph at Denver International Airport.
      In estimated 2 inches of rain fell in less than an
        hour...causing two secondary roads in Buck and Miller gulches
        in the Hi Meadows fire burn area to wash out.  Water
        also covered Jefferson County Road 68 which connects to
        Bailey.  Homeowners in Pine Valley Estates attempted to
        divert some of the runoff by piling stacks of hay on the
        hillside above their homes.  Torrential rainfall...up to
        3.50 inches an hour...caused flash flooding along Whiskey
        Gulch near Elizabeth.  Several roads were washed out and
        basements flooded during the storm.  Along County Road 13...
        about 6 miles north-northwest of Elizabeth...rushing water
        washed away a 15-foot section of the road.  The floodwaters
        forced debris and mud into four huge culverts...sending water
        over the road.  At Denver International United
        Airlines ground crew worker was struck by lightning as she
        was loading a Boeing 747 jumbo jet.  The woman was injured
        when lightning either hit the jet or the loading equipment
        that she was working near.  The 25-year-old woman received
        only minor injuries.
      In 2006...outflow from severe thunderstorms to the southeast
        of metro Denver produced southeast sustained winds to 35
        mph with gusts as high as 52 mph at Denver International
        Airport during the late evening.
      In 2011...a deluge of heavy rain occurred in and around
        Nederland when the storm dumped nearly 2 inches of rain in
        30 minutes. The heavy rainfall washed out hillsides and
        dirt roads. In Nederland...a culvert became blocked with
        debris and forced the water to spread into a nearby
        bookstore. The rainfall also damaged several residential
        roads in the Sunnyside Subdivision and Navajo Road became
        impassable. Several homes suffered flood damage as the
        runoff from a nearby Beaver Creek jumped its banks and
        flooded rooms and bedrooms of nearby
18    In 1874...the temperature climbed to 90 degrees or more for the
        18th consecutive day...setting a record.  The record was
        equaled from July 6th through the 23rd in 1901.
      In 1902...a thunderstorm produced northwest winds sustained to
        45 mph with gusts to 48 mph along with rain and hail.
        Total precipitation was 0.53 inch.
      In 1911...a shower produced north winds sustained to 44 mph.
      In 1958...1 1/2 inch diameter hail fell 9 miles west-southwest
        of Stapleton Airport.
      In 1981...a thunderstorm bombed Evergreen with about 2 inches
        of rain in 45 minutes.  A heavy hailstorm left 5 to 7 inches
        of hail on the ground in some places and stopped the Colorado
        Open Golf Tournament at Hiwan.
      In 1985...over 2 inches of rain doused the southwest suburbs
        of Denver.  Street flooding occurred in the Montbello area
        of northeast Denver.
      In 1992...nickel size hail fell across central Douglas County
        near Castle Rock and Sedalia.  One inch diameter hail fell
        in Castle Rock.
      In 1993...thunderstorm winds gusted to 60 mph at Strasburg
        east of Denver.
      In 2004...heavy thunderstorm rainfall caused flooding over
        parts of the Virginia Canyon Road near Idaho Springs.
        Several sections of the roadway were washed out.  The
        road was closed temporarily for repairs.
18-19 In 2003...heavy rain producing thunderstorms caused flash
        flooding across southern metro Denver.  Automated rain
        gages measured 2 to 3 inches of rain in less than an
        hour.  The heavy rainfall caused many intersections and
        underpasses to flood...stranding motorists.  Sections of
        I-25 and I-225 were closed due to the high water.
18-2  In 1987...a streak of 16 consecutive days of 90 degrees
        ranked 4th on the list of hot streaks.  The record of
        24 consecutive days was established in the summer of
19    In 1875...recent heavy rains produced high waters on many
        creeks and rivers in the area...which threatened the
        destruction of property at some locations.  Cherry Creek
        in the city was running the highest in 10 years.  Heavy
        rain in the mining regions over the last 2 days resulted
        in water running "everywhere" and the suspension of some
      In 1881...a thunderstorm passing across the city produced
        lightning with no rain.  A woman was seriously injured
        when struck by lightning several blocks from the weather
        office in downtown Denver.
      In 1934...the temperature reached a high of 100 degrees in
        downtown Denver.
      In 1965...hail...rain...and lightning hit west metro Denver.
        Hail stones as large as 1 1/2 inches in diameter accumulated
        to a depth of 2 inches in Evergreen where 2.95 inches of
        rain in 2 hours caused some flooding in the business section
        of the town.  Lightning caused some power outages.
      In 1973...two funnel clouds were observed 5 miles southeast of
        Littleton.  The same funnel clouds were observed for 20
        minutes...5 miles west and 5 miles west-southwest of Arapahoe
        County Centennial Airport.
      In 1975...lightning injured a man in Denver and caused power
        outages in Aurora...Lakewood...Westminster...and west Denver.
      In 1984...strong thunderstorm winds gusting to 45 mph shattered
        7 large plate glass windows at Stapleton International
      In 1985...a tornado touched down in the Surrey Ridge area of
        northern Douglas County...just west of I-25.  Ten homes were
        damaged; one under construction was nearly destroyed.  Two
        vehicles were thrown off I-25 injuring three people.  A
        pick-up truck was thrown 50 feet by the twister.  In
        addition...a cluster of severe thunderstorms pounded all
        of metro Denver with torrential rain...hail...and wind.  The
        heaviest rain fell in Aurora where one location reported
        2.37 inches in just 40 minutes.  One location in northeast
        Aurora received a total of 4.30 inches from the storm.
        There was extensive street and basement flooding...and a
        number of roads were damaged or washed out.  An Aurora boy
        suffered minor injuries when he was washed into a drainage
        ditch.  Golf ball size hail in Aurora piled up to 5 inches
        deep.  An inch of rain fell in 20 minutes at Stapleton
        International Airport...closing it to air traffic for an
        hour.  Up to 1 1/2 inches of rain fell in just 15 minutes
        over central Denver with the high water closing I-25.  The
        water was so deep on the freeway...that one vehicle was
        completely submerged and people were diving into the water
        from the freeway overpass.  Three homes in Littleton were
        damaged by lightning.  Wind blew out several windows from
        a high rise apartment building in southeast Denver.
        Rainfall totaled 1.51 inches at Stapleton International
      In 1997...torrential rain and damaging hail pummeled eastern
        sections of metro Denver.  Hail up to 1.25 inches in
        diameter fell at the National Weather Service office on the
        site of the former Stapleton International Airport.  The
        hail continued for about 15 minutes and accumulated to a
        depth of 2 to 3 inches...causing extensive damage to cars in
        the area.  Heavy rainfall totaled 3.83 inches in about an
        hour from the nearly stationary thunderstorm.  Numerous cars
        stalled along I-70...and several homes were flooded in east
        Denver.  The roof of a building collapsed under the weight
        of the water.  The next day several "fatalities" were
        discovered near the National Weather Service office; two
        prairie dogs were found dead along with three rabbits that
        either drowned or were killed by the large hail.
      In 1999...lightning struck two residences in Littleton...but
        caused only minor damage.  Lightning triggered a fire at a
        residence in Cherry Hills Village.  A small portion of the
        roof and ceiling were damaged before the fire could be
      In 2000...hail as large as 1.25 inches in diameter fell near
        Roggen northeast of Denver.
      In 2004...heavy rainfall caused flooding on the Virginia Canyon
        Road near Idaho Springs...which had to be closed for repairs.
      In 2006...the temperature climbed to a high of 100 degrees.  The
        high temperature was not a record maximum for the date.
     In 2007...a severe thunderstorm produced large hail...up to 1
        inch in diameter...about 6 miles north of Northglenn.
19-23 In 2005...the high temperature climbed above 100 degrees on
        each of the 5 days with readings of 101 on the 19th...105 on
        the 20th...104 on the 21st...and 102 on both the 22nd and 23rd.
        A new record maximum temperature for the month of July of 105
        degrees was set on the 20th...which also equaled the all time
        record maximum for Denver of 105 degrees first set on August
        8th in 1878.  Daily maximum temperature records were set on
        each day...and the 5 day period equaled the record for the
        most consecutive days of 100 degrees or more first set from
        July 4th through 8th in 1989.  The intense heat resulted in
        a high use of electricity for cooling purposes.  The demand
        for electric power exceeded the supply and rolling black-outs...
        each lasting about an hour...were scheduled across metro Denver
        during the afternoons and early evenings.
20    In apparent thunderstorm produced sustained northwest
        winds to 45 mph with gusts to 51 mph.
      In 1939...the high temperature reached 102 degrees in downtown
        Denver.  This was the highest temperature recorded since
        August 8...1878...a period of 61 years...and the third highest
        temperature of record at the time.  Six miles to the east...
        at Denver Municipal Airport...the maximum temperature reached
        104 degrees.  A dry period during mid-July...combined with low
        relative humidities...resulted in an unusually large number
        of forest fires in the mountains west of Denver.
      In afternoon thunderstorm caused two lightning
        deaths.  The men were struck by lightning near the Denver
      In 1951...a thunderstorm wind gust to 54 mph was recorded at
        Stapleton Airport.
      In 1965...heavy rain west of Denver damaged roads and bridges.
        Two bridges in Golden were washed out.  Lightning in Denver
        caused some power failures and fires...mostly in the northeast
        section of the city.  Heavy rain caused street flooding in
        the City of Denver.  Hail as large as 1/2 inch in diameter
        and 0.40 inch of rain in 5 minutes were measured at
        Stapleton International Airport where precipitation totaled
        1.09 inches.  Lightning damaged a house in Littleton...and
        caused a power outage in Idaho Springs.
      In 1973...lightning damage was reported west of Arvada.
      In 1975...heavy rains caused flash flooding across metro
        Denver...resulting in the closing of several streets and
        damage to numerous homes and businesses.  Hail 1/2 to 3/4
        inch in diameter was reported.
      In 1976...heavy thunderstorms caused flooding of streets in
        southeast Denver and western Arapahoe counties.  A total of
        3.35 inches of rain was measured at Kassler southwest of
      In 1978...a girl was injured by lightning at a country club
        southwest of Denver.
      In 1984...heavy rain was reported just east of Buckley Field in
        Aurora where 1.15 inches fell in just 45 minutes.
      In 1986...thunderstorms dumped heavy rain across metro Denver
        causing extensive street flooding...power outages...and
        basement flooding.  The greatest recorded rainfall was 4.39
        inches in Lakewood.  In extreme northwest Denver...2.29
        inches of rain fell in just 20 minutes.  Arvada was drenched
        with 2.60 inches of rain...and over an inch fell in southeast
        Denver and adjacent sections of Aurora.
      In 1990...heavy thunderstorm rains caused flash flooding in
        sections of Littleton where 1.20 inches of rain fell in
        less than 30 minutes.  The deluge caused Dry Creek to jump
        its banks...causing damage to residential streets...curbs...and
        sidewalks.  Nearly 100 vehicles were stranded for a time in
        fender-deep water when sewers and drainage ditches became
        choked with debris.  The heavy runoff submerged many
        Littleton streets and intersections.
      In 1992...strong thunderstorms moved slowly through east metro
        Denver...producing rainfall up to 2.50 inches in a short time.
        Weather spotters reported 0.75 to 1.00 inch of rain in less
        than 30 minutes.  Many areas of southeast Denver were
        flooded...including I-25 where up to 6 feet of water
        filled some underpasses.  Hail to 3/4 inch in diameter
        fell in Aurora.
      In 1995...a tornado touched down briefly in an open field
        near Strasburg.  Thunderstorm winds gusted to 58 mph at
        Centennial Airport.
      In 1996...strong thunderstorm winds damaged the building of
        a telephone installation company in the City of Denver.
      In 1998...the high temperature reached 100 degrees at
        Denver International Airport.
      In 2006...heavy rainfall in the Overland Wildfire burn area
        caused minor flash flooding in Jamestown.  The roads behind
        the Jamestown Fire Hall were washed out...when a culvert was
        blocked by debris.  A rockslide was also reported in town.
      In 2009...a severe thunderstorm produced damaging winds...large
        hail and very heavy rain across the western and southern
        suburbs of Denver.  Widespread damage was observed in the
        cities of Arvada...Lakewood and Wheat Ridge.  The intense
        straightline winds were the result of a wet microburst which
        downed hundreds of trees and snapped power poles.  Wind
        gusts to 80 mph were reported along with hail up to 1 3/4
        inches in diameter.  The combination of wind and hail
        caused widespread damage to homes and vehicles.  The damage
        claim estimates totaled 350 million dollars; about 32900
        claims were filed for homes...while another 19500 claims
        were filed for vehicles.  As many as 90000 homes and
        businesses were left without power.  In some areas it took
        up to 3 days to completely restore electrical service.
        Minor injuries were reported from broken glass during the
        storm...but no one was hospitalized.  The storm crippled the
        computers at the Colorado Crime Information Center in
        Lakewood for nearly 3 hours.  One weak tornado touched down
        near Parker but did no damage.  In southern Weld County...
        severe thunderstorms produced widepread damage over 150
        square miles of farmland.  In all...400 farms were directly
        impacted by severe weather.  Damage to crops alone was
        estimated to 3 million dollars.  At Denver International
        Airport...a peak wind gust to 48 mph was observed from the
        northeast.  In addition...1.01 inches was measured at the
      In 2013...severe thunderstorms produced large hail...ranging in
        size from nickel to golfball...across portions of Arapahoe...
        Denver...Elbert and Weld Counties. In addition...damaging wind
        gusts to 60 mph snapped large tree branches in Thornton and
        3 miles west-southwest of Buckley AFB.  In Bennett...hail up
        to 1 1/2 inches in diameter was reported. At Denver
        International Airport...a peak wind gust to 58 mph was
        recorded from the northeast.

        of streets and considerable damage to private property.
        The lightning was brilliant and continuous during the
        storm.  Seven buildings were struck by lightning in the addition to many places where it struck only the
        ground.  A magnificent example of ball lightning was
        observed.  When about 200 feet above the house tops...the
        ball exploded and broke into 7 or 8 different balls...each
        about 6 inches in diameter.  Upon reaching about 20 feet
        above the ground...these balls broke into small fragments
        about 3 inches long and 1/2 inch wide.  A shed situated
        in an alley about one block away was literally covered
        with these sparks.  After the storm was over...the shed
        and adjacent area showed no trace of the event.  Not the

      In 1973...minor thunderstorm wind damage was reported in
      In 1983...heavy thunderstorms dumped torrential rain and large
        hail across metro Denver.  The most serious problems were
        caused by heavy rainfall in the foothills...which produced
        flooding on Bear Creek.  Runoff from 3 inches of rain in
        45 minutes at Kittredge caused Bear Creek to rise 5 feet in
        10 minutes at Morrison...washing out two bridges.  One bridge
        collapsed...plunging a fire truck into the water...but the
        occupants were not injured.  The town was evacuated for 2
        hours.  Evergreen was drenched with 2.61 inches of rain in
        30 minutes...which caused street flooding along with power
        outages.  Hail to golf ball size damaged cars.  A deck on a
        house east of Evergreen was washed away.  At Idaho Springs...
        2 inches of rain fell in 45 minutes.  Golden received

        Aurora street.
      In 1991...heavy rains caused extensive flooding across north
        metro Denver.  Ralston Creek in Arvada flowed out of
        its banks.  At the intersection of I-25 and I-70...up to 8
        feet of water covered the highway.  A foot of water covered
        a stretch of I-70 in northwest Denver.  Thunderstorm

        in diameter in Commerce City and near Brighton.
22-23 In 1991...heavy rains over the Palmer Divide and along the
        Front Range caused the South Platte River to flood from

        banks at several locations with water covering the roads
        through the night.  Only minor damage was reported.
