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

1-3   In 2023...a prolonged period of strong winds and heavy snow
        occurred across the mountains and foothills.  Peak wind
        gusts included: 93 mph at the NCAR Mesa Lab...89 mph near
        Winter Park...85 mph at the junction of state highways 93
        and 72...and 76 mph just south of Boulder.  Storm totals
        included: 19.5 inches near Berthoud Pass...16.5 inches
        near Loveland Pass...and 13.5 inches near Lake Eldora.
1-5   In 1913...the 1st marked the start of the heaviest 5-day
        total snowfall in the city`s history.  During this period
        snowfall totaled 45.7 inches.  Starting on the 1st...snow
        fell intermittently for 3 days and accumulated a little
        over 8 inches.  On the 4th and 5th...an additional 37.4
        inches of snow fell.  At Georgetown in the foothills west
        of Denver even more snow fell...86 inches over the 5 days
        with the most...63 inches...on the 4th.  In Colorado...snowfall
        was heavy along the eastern slopes of the mountains from the
        Palmer Divide north.  High winds during the storm caused
        heavy drifting...which blocked all transportation.  Snow
        cover of an inch or more from the storm persisted for
        60 consecutive days from the 1st through January 29...1914.

      In 1990...strong downslope winds raked the eastern foothills
        and most of metro Denver.  A wind gust to 87 mph was
        recorded at Rollinsville with wind gusts to 58 mph in
        Arvada and 55 mph in Lakewood.  West winds gusted to
        48 mph at Stapleton International Airport on the 2nd.
      In 1997...heavy snow fell in the foothills.  Conifer

        temperature records were set...including the all time
        record high temperature for the month of 79 degrees on
        the 5th.  Daytime highs were balmy with 14 days in the
