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

10-17 In 2018...the high temperature equalled or exceeded 90 degrees for
        8 consecutive days; breaking the previous streak of 7 consecutive
        days in the month of September.
10-18 In 2018...the high temperature equalled or exceeded 90 degrees for 9
        consecutive days; marking the first time such an occurrence has
        taken place in the month of September.  It also brought September
        of 2018 into a 4-way tie for most 90 degree + days in the month.
        Previous years included 2017...2005 and 1895. During the streak...4
        record high temperatures were either tied or broken...and one
        record high minumum temperatures was broken.
15-17 In 2000...unusually hot weather for so late in the season
        occurred when temperatures climbed into the 90`s setting
        daily record maximum temperatures on each of the 3 days.
        The high temperature was 92 degrees on the 15th and 95
        degrees on both the 16th and 17th.
15-19 In 1906...rain on 5 consecutive days totaled 1.61 inches.
        A thunderstorm occurred on the 17th.  High temperatures
        ranged from 48 degrees on the 16th to 65 degrees on the
        15th.  Low temperatures were in the lower to mid 40`s.
16-19 In 1971...a record breaking early fall snow storm caused
        extensive damage to trees and utility lines.  The heavy wet
        snow occurred with little wind...but caused record breaking
        cold temperatures for so early in the season.  Snowfall
        totaled 15.6 inches at Stapleton International Airport
        with most of the snowfall...12.0 inches...occurring on the
        17th.  This was the heaviest first snow of the season.
        The maximum snow depth on the ground was 13 inches.
        Record low temperatures were set on three consecutive days:
        31 degrees on the 17th...23 degrees on the 18th...and 20
        degrees on the 19th...which was also a new all-time record
        minimum for the month at that time.  Record low maximum
        temperatures were set on 4 consecutive days:  48 degrees
        on the 16th...35 degrees on the 17th...40 degrees on the 18th...
        and 42 degrees on the 19th.
17    In 1873...brisk west to northwest winds at different times
        during the day...generally in sudden gusts...spread a good
        deal of dust into the city.
      In 1953...strong winds caused thousands of dollars in damage
        to Boulder.  The winds blew for most of the day with great
        gustiness...and a freak twister was reported during the
        afternoon.  Damage was minor.  A thunderstorm wind gust
        to 40 mph caused some blowing dust at Stapleton Airport.
      In 1992...a tornado touched down briefly near Bennett.  No
        damage was reported.
      In 1993...severe thunderstorms rumbled across northern
        portions of metro Denver.  Hail as large as 1 3/4 inches
        in diameter fell in Brighton.  Dime size hail damaged
        several roofs of residences in Lafayette.
      In 2000...for the second day in a row...the high temperature
        of 95 degrees at Denver International Airport broke three
        record temperature extremes:  the high temperature broke
        the previous record for the day of 94 degrees set in 1895;
        it marked the warmest it has been for so late in the season;
        it also marked the 61st day in the year that the temperature
        had equaled or exceeded 90 degrees...eclipsing the record
        equaled the previous day and first set on September 29...
        1994.
