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

13-5  In 2008...a streak of 24 consecutive days of 90 degrees...from
        July 13th to August 5th...shattered the previous record of 18
        consecutive days established in 1901 and 1874. Ironically...
        no 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.
18-2  In 1987...from July 18th to August 2nd...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 2008.
27-31 In 1956...96 percent of the total precipitation for the month
        of July occurred over the last five days of the month.
        Heavy thunderstorms produced 4.00 inches of rainfall at
        Stapleton Airport.  This amount of precipitation in 5 days
        or less had been exceeded only 3 times in previous record.
        The last time had been in December of 1913 as snow.
        Considerable property damage occurred across metro Denver
        from flooding.
28-30 In 1889...from the 28th to the 30th...dense smoke from
        forest fires in the mountains obscured the sun over
        the city for three days.
      In 1971...a vigorous cold front late on the 28th produced
        northeast wind gusts to 39 mph and record breaking cold
        temperatures on the 29th and 30th.  The temperature dipped
        to 47 degrees on the 29th and 43 degrees on the 30th...
        setting record minimums for the dates.  Upslope cloudiness
        along with rain and fog early on the 29th helped set a
        record low maximum temperature of 58 degrees for the date.
29    In 1878...a total eclipse of the sun was observed at 2:20 PM.
        From before to during the eclipse...the temperature in the

        temperature fell from 89 degrees to 83 degrees.
      In 1880...heavy thunderstorm rain and hail flooded streets
        and ditches.  In 25 minutes...0.76 inch of rain fell on the
        city along with large hail to 3/4 inch in diameter.  There
        were no strong winds with the storm.
      In 1890...a thunderstorm produced sustained west winds to
        48 mph with gusts to 60 mph...but only 0.01 inch of rain.
      In 1956...heavy rain and hail fell over west and north Denver.
      In 1964...hail to 3/4 inch in diameter fell at Lowry Airfield.
      In 1978...a small tornado was sighted just east of Parker.  No
        damage was reported.
      In 1989...heavy rain drenched all areas of the Front Range...
        both in the foothills and adjacent plains.  Amounts of 1 to
        3 inches were general over the area.  Damage was confined to
        a few minor road washouts and some street...basement...and
        crop flooding.  Thunderstorm rainfall totaled 1.44 inches at
        Stapleton International Airport where north winds gusted to
        43 mph.  Lightning struck a 250 thousand dollar home near
        Nederland and started a fire which destroyed all of it
        except two garages.  Lightning started a fire in a home in
        Evergreen.  It reached the house by hitting a tree...then
        traveling through a metal clothesline strung between the
        tree and the building.
      In 1995...thunderstorm winds gusted to 59 mph in Brighton.
        Thunderstorm winds from the south-southeast gusted to 41

        Denver.
      In 1997...heavy rain caused flooding in an apartment building
        in Westminster.  Several residents had to be evacuated from
        their apartments.  A woman in Aspen Park received minor
        injuries...when lightning passed through an office window
        and struck her.  She suffered temporary blindness for about
        15 minutes.
      In 2003...hail as large as 1 inch in diameter pelted Conifer...
        Highlands Ranch...and Franktown.
      In 2022...two brief landspouts developed...one north of Denver
        International Airport and the other northeast of Buckley AFB.
        Both were small developed in open fields. No damage was
        observed.  At Denver International Airport...a thunderstorm
        produced 0.30 inch of rainfall.  In addition...a peak wind
        gust to 32 mph was observed from the south.
29-30 In 1997...from the 29th into the 30th...heavy rain caused
        flooding and flash flooding in central portions of Adams
        and Arapahoe Counties.  Two homes were extensively damaged
        when water flooded the basements and adjacent pasture area
        in Strasburg.  Water 4 to 5 feet deep had pooled in the
        lower lying areas of the town.  A portion of Quincy Road
        was closed in Arapahoe County when 4 feet of water covered
        the roadway. Rainfall totaled 3.06 inches at Denver
        International Airport...establishing a new record for
        24-hour rainfall in July.  The previous record was 2.42
        inches set in 1965 on the 24th and 25th.
