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

8-10  In 1985...Indian summer came to an abrupt end when a winter
        storm dumped 10 to 18 inches of snow in the Front Range
        foothills and 6 to 10 inches across metro Denver...snarling
        traffic and causing flight delays of up to 3 hours at
        Stapleton International Airport.  The temperature plunged
        from a high of 66 degrees on the 8th to a low of only 13
        degrees on the 9th...after the passage of a vigorous cold
        front with northeast winds gusting to 32 mph.  The
        temperature climbed to only 19 degrees on the 10th...setting
        a record low maximum for the date.  Snowfall totaled 7.3
        inches at Stapleton International Airport with most of the
        snow...7.1 inches...falling on the 9th.
 10    In 1897...west chinook winds sustained to 51 mph with gusts
        to 60 mph warmed the temperature to a high of 64 degrees.
      In 1915...southwest winds were sustained to 41 mph with gusts
        as high as 44 mph.
      In 1955...strong winds raked the eastern foothills.  A wind
        gust to 80 mph was recorded atop Rocky Flats south of
        Boulder where some damage occurred.
      In 1995...snowfall totaled 6 to 9 inches in the foothills
        west of Denver...while only 2.2 inches of snow fell
        at the site of the former Stapleton International Airport.
        North-northeast winds gusted to 31 mph at Denver
        International Airport.
      In 1998...strong bora winds gusting from 70 to 92 mph coupled
        with blowing snow created whiteout and slick black ice
        conditions at the base of the foothills west of Denver.
        State Highway 93 between Golden and Boulder and C-470...
        near the Morrison interchange were closed for several
        hours due to multiple car accidents.  Dozens of motorists
        were stranded until weather conditions improved.  A small
        motor home was a total loss when it caught fire after
        being blown on its side by strong crosswinds.  A man was
        injured when he was blown off a vehicle while attempting
        to rescue the occupants.  Wind gusts included:  92 mph atop
        Blue Mountain near Coal Creek Canyon...83 mph atop Fritz
        Peak near Rollinsville...and 77 mph at Jefferson County
        Airport near Broomfield.  West winds gusted to 36 mph at
        Denver International Airport.
      In 2000...freezing drizzle was widespread across northeastern
        Colorado with the heaviest amounts near the foothills in
        the evening.  The freezing drizzle made many highways icy
        and slick...which contributed to a number of traffic
        accidents.  Some highways across metro Denver were closed
        at times...including portions of State Highway 119 between
        Boulder and Longmont and U.S. 36 between Westminster and
        Boulder.  State Highway 93 between Boulder and Golden atop
        Rocky Flats became nearly impassable due to a coating of
        ice by late evening.
10-11 In 1911...a strong cold front produced snow and a cold wave.
        The temperature dropped 68 degrees from a high of 66 degrees
        at 12:40 PM on the 10th to a low of 2 degrees below zero at
        7:15 AM on the 11th.  The low temperature of 23 degrees at
        midnight on the 10th was also the high temperature on the
        11th.  Northeast winds were sustained to 42 mph with gusts
        to 51 mph.  Snowfall was only 2.5 inches.
      In 1982...up to 4 inches of snow fell over the higher terrain
        between Denver and Colorado Springs.  Winds gusted to 50
        mph along the foothills.  Rainfall totaled 0.27 inch
        with only 0.1 inch of snow on the 11th at Stapleton
        International Airport where north winds gusted to 39 mph.
        Dense fog with visibilities as low as zero persisted all day
        on the 10th.
10-14 In 2014...an Arctic cold front on the 10th...associated with a
        strong storm system over the northern Rockies blasted into
        northeast Colorado.  The temperature in Denver plummeted
        from the high of 64 degrees at 4:37 pm to 34 degrees by
        5:53 pm.  The temperatures continued to fall and dropped
        into the teens by early evening.  The Arctic airmass
        remained entrenched over the region through the morning of
        the 14th...with the high temperatures failing to reach
        the teens from the 11th through the 13th.  This was the first
        time since records have been taken in Denver...dating back to
        1872...that there were three consecutive days with the
        maximum temperatures remained below 20 degrees in the month
        of November.  In addition to the frigid temperatures...0.1
        inch of snowfall was observed on 11th at Denver International
        Airport...which marked the first measureable snowfall for the
        season. An additional 2.2 inches of snowfall was measured on
        the 12th.  Several temperature records were broken.  A
        record low max of 16 degrees on the 11th broke the previous
        record of 19 set back in 1916.  A record low max of 6 degrees
        on the 12th broke the previous record of 9 degrees...also set
        in 1916.  The record low of -13 on the 12th...shattered the
        previous record of -4 degrees set back in 1872.  Even more
        impressive...the record low of -14 degrees on the 13th broke
        the previous record of -3 degrees set back in 1916. The
        sudden drop in temperatures on the 10th...followed by several
        days of sub-freezing temperatures chilled trees to the core.
        The record drop in temperatures...preceded by mild fall
        temperatures...damaged or killed scores of trees across the
        I-25 Corridor and northeast plains. At the time...the trees
        were not finished with the hardening process that enables
        them to withstand winter weather. Many were instantly flash-
        frozen...and some would not show signs of damage until spring
        of 2015. Of the 2.2 million trees in the city of Denver
        alone...tens of thousands were killed from the November frost.
        Denver estimated a citywide loss of more than 10 million
        dollars.
