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

2-5   In 1946...a major snow storm dumped 30.4 inches of heavy
        snowfall downtown and 31.0 inches at Stapleton Airport.
        The winter storm closed schools and disrupted all forms of
        transportation in the city.  The greatest depth of snow on
        the ground was 28 inches at the airport.  The duration of
        the snowfall...from 4:22 AM on the 2nd to 3:08 AM on the 5th...
        a total of 70 hours and 46 minutes...is the second longest
        period of continuous precipitation on record and the second
        heaviest snowfall of record at the time in Denver.  The 17.7
        inches of snowfall on the 2nd and 3rd was the greatest 24-
        hour snowfall ever recorded during the month of November.
        Buses and street cars had a difficult time...and many cars
        were abandoned along roadsides and streets for several days.
        Secondary roads in rural areas were blocked for 2 to 3
        weeks.  Several buildings in the city collapsed or were
        damaged from the weight of the heavy snow.  Football games
        were canceled.  Livestock losses were high over eastern
        Colorado.  The precipitation from this storm alone exceeded
        the greatest amount ever recorded in Denver during the
        entire month of November previously.  The precipitation
        recorded downtown was 2.03 inches...and the previous record
        for the entire month of November was 1.95 inches in 1922.
        North winds were sustained to 26 mph on the 2nd.
3-4   In 1994...a fast moving snow storm dumped 8 to 9 inches of
        snow on Boulder...Broomfield...and Lafayette.  Snowfall
        totaled only 1.8 inches at Stapleton International Airport
        where on the 3rd east winds gusted to 20 mph and some
        freezing drizzle fell.
      In 2022...a massive crash occurred as freezing temperatures and
        icy conditions followed the first snowfall of the season...
        most of which fell the previous evening. Hazardous conditions
        developed in Denver along an elevated portion of 6th Avenue
        during the early morning commute.  The crash involved
        approximately 100 vehicles.  There were no serious injuries...
        although one driver had to be extricated from a vehicle. The
        accidents occurred between Kalamath Street and Federal Boulevard.
        Numerous tow trucks took damaged or inoperable vehicles to a
        parking lot outside Empower Field at Mile High. The icy road
        conditions made it impossible for drivers to prevent from
        slamming into each other.  A major cleanup had to take place
        before 6th was reopened later in the morning.  The closure
        lasted approximately 5 hours.  Several crashes occurred along
        Interstates 25 and 70...and included a multi-vehicle accident
        on the onramp from US 36 to I-25.  Storm totals in the
        mountains and foothills generally ranged from 4 to 12 inches.
        At the National Weather Service in Boulder...6.6 inches of
        snowfall was observed.  At Denver International Airport...4.5
        inches was observed.
4     In 1940...a trace of snow fell in downtown Denver.  This
        marked the start of the shortest snow season on record...
        167 days...through April 19...1941...when 0.4 inch of snow
        fell.
      In 1959...high winds caused damage in many areas of the
        eastern plains.  In Denver...winds averaged 40 mph with
        gusts to 70 mph.  Some damage was reported to utility
        lines...signs...and vehicles.  Northeast winds were
        sustained to 30 mph at Stapleton Airport.
      In 2017...strong winds developed over the Palmer Divide.
        Peak wind gusts included 66 and 61 mph near Monument.
4-5   In 1933...the first measurable snow of the season totaled
        only 2.5 inches.  This was the only measurable snow
        of the month.  Northwest winds were sustained to
        27 mph on the 4th.
      In 1951...heavy snowfall of 5.7 inches was measured at
        Stapleton Airport where northwest winds gusted to 32
        mph.
      In 2022...high winds developed in the Front Range Foothills.
        Peak wind gusts included:  84 mph near Crisman...80 mph
        near Aspen Springs and Dumont...77 mph near Floyd Hill
        and Pinecliffe...with 75 mph near Sunshine.  At Denver
        International Airport...a peak gust to 34 mph was observed
        from the northwest.
