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

25-31 In 1980...temperatures were unusually warm during the week
        between Christmas and New Year`s.  High temperatures for
        the week ranged from the mid-50`s to the mid-70`s.  Four
        temperature records were set.  Record highs occurred on
        the 26th with 68 degrees...the 27th with 75 degrees...and
        the 30th with 71 degrees.  A record high minimum
        temperature of 41 degrees occurred on the 27th.
27-29 In 1983...a second surge of bitter cold air in less than a
        week was less intense.  Record breaking low temperatures
        of 12 degrees below zero on the 28th and 15 degrees below
        zero on the 29th were accompanied by 3.7 inches of snowfall
        and northeast winds gusting to 23 mph.
28-29 In 1906...a trace of snow fell on both days...which along
        with a trace of snow on the 5th...was the only snow of

        December on record.
      In 1970...wind gusts to 87 mph were recorded at the National
        Center for Atmospheric Research in Boulder.  Winds gusted
        to only 46 mph in downtown Boulder.  Damage was minor.
      In 2006...while metro Denver residents were still digging
        out from the heavy snowfall and blizzard that occurred
        on December 20-21...the second major winter storm in a
        week buried the city and the eastern foothills again in
        more deep snow.  Heavy snowfall ranged from 1 to 2 1/2
        feet in the foothills and from 6 to 18 inches across the
        city.  Another slow moving storm system centered over the
        Texas panhandle produced deep upslope flow over the high
        plains and against the Front Range Mountains.  The storm
        produced blizzard conditions over the plains mainly south
        of Interstate 76.  Interstate 70 as well as other roads
        and highways was closed from Denver to the Kansas line due
        to snow and blizzard conditions.  Greyhound was forced to
        cancel all bus trips from Denver.  The heaviest snow fell
        in and near the foothills and south of Denver over the
        Palmer Divide...where north winds sustained at speeds of
        20 to 30 mph with gusts to 40 mph piled the snow into
        drifts 4 to 14 feet deep.  In the city...the heavy snowfall
        persisted for a total of 29 hours.  Snowfall totals across
        metro Denver included:  17.5 inches at Ken Caryl; 15 inches
        3 miles south-southeast of Morrison; 14 inches in Boulder

        inches in Lakewood and Thornton.  Officially...snowfall
        totaled 8.0 inches at Denver Stapleton.  North winds
        sustained to 25 mph with gusts to 32 mph produced some
        blowing snow at Denver International Airport.  In the
        city...this second storm increased the total snowfall for
        the month to 29.4 inches...making the month the third
        snowiest on record.  In the foothills the snow fell at a
        rate of 3 to 4 inches an hour at times.  Total snowfall
        in the foothills included:  30 inches near Genesee;
        29.5 inches 12 miles northwest of Golden; 25 inches in

        Reservoir.  The total cost of snow removal just at
        Denver International Airport from this storm and the
        previous storm was in tens of millions of dollars.  The
        airport estimated up to 6.7 million dollars in extra
        costs for
        chemicals...and other expenses.  The two storms cost the
        airport 4.6 million dollars in loss concession revenues.
        United Airlines reported lost revenue of over 25 million
        dollars from the two storms...while Frontier Airlines
        lost an estimated 12.1 million dollars.
