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

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.
10-13 In Arctic cold front associated with a strong storm
        system over the northern Rockies blasted into northeastern
        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...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 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

        the previous record of -3 degrees set back in 1916.
11    In 1901...a trace of rain fell in the morning...and a trace of
        snow fell in the afternoon.  This was the only snowfall and
        precipitation for the month...ranking it the driest November
        on record...along with November of 1899 and 1949.  The month
        also ranks as the second least snowiest November...along with
        Novembers in other years.

        56 mph warmed the temperature to a high of 56 degrees.

        at 5:45 PM.  A low temperature of 2 degrees was recorded
        overnight.  Northeast winds were sustained to 33 mph with
