... Today in Metro Denver weather history...

18-23 in 2003... an extended warm spell resulted in 5 new temperature
        records. The high temperature of 84 degrees on the 18th
        equaled the record high for the date. High temperatures
        of 86 degrees on the 19th... 83 degrees on the 21st... and 84
        degrees on the 22nd were record highs for the dates. Low
        temperature of 49 degrees on the 23rd was a record high
        minimum for the date. Low temperatures during the period
        were in the 40's and lower 50's.
19-20 in 1990... an early winter storm dumped heavy snow across
        Metro Denver. Snowfall amounts ranged from 4 to 8 inches
        in the foothills above 6500 feet elevation... 4 to 7 inches
        in The Castle Rock area... and 2 to 5 inches across most of
        Metro Denver and Boulder. Snowfall totaled 3.6 inches at
        Stapleton International Airport where northwest winds
        gusting to 48 mph kicked up some blowing dust shortly
        after a cold frontal passage on the 19th. However...
        temperatures were warm enough to keep most roadways wet
        and slushy at lower elevations.
19-23 in 1906... heavy snowfall totaled 22.7 inches in the city over
        the 5 days. Rain changed to snow on the evening of the

        from 8:00 PM on the 20th to 8:00 PM on the 22nd. The most
        snow on the ground was 13.3 inches on the evening of the
        23rd. This was the first snow of the season and the only
        snow of the month. Winds during the storm were from the
        north at sustained speeds of 20 to 30 mph each day.
        Temperatures during the storm were generally in the 20's.
20 in 1878... between 3:00 PM and 4:00 PM wind speeds averaged
        48 mph with a maximum 1 minute sustained velocity to 96
        mph at both 3:27 PM and 3:48 PM in downtown Denver. This
        is the highest sustained wind speed ever recorded in the
        city.
      In 1986... a rare late October thunderstorm produced 3/4 inch
        diameter hail at Centennial Airport. Hail piled up 2 1/2
        inches deep... causing some street flooding in south Metro
        Denver.
20-21 in 2007... a storm system brought heavy snow to the southern
        Denver suburbs as well as the Palmer Divide south of
        Denver. Storm totals included: 7.5 inches near Castle
        Rock... Lone Tree and Greenwood Village... with 6.5 inches at
        Elizabeth. Snow drifts up to 2 feet deep were observed 6
        miles south-southwest of Elizabeth. In the Denver
        Stapleton area... 2.0 inches of snow was observed.
      In 2009... heavy snow developed along the Palmer Divide
        south and southeast of Denver as a storm system tracked
        across southern Colorado and northern New Mexico.
        Storm totals included: 15 inches... 15 miles north of
        Elizabeth... 9 inches... 5 miles south-southwest of Arapahoe
        park; 8 inches in Highlands Ranch... 5 miles south-
        southeast of sedalia; 6.5 inches... 8 miles southwest of
