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

9-10 in 1933... heavy rain over the Cherry Creek... Plum Creek... big
        Dry Creek... and little Dry Creek watersheds caused flooding
        on the South Platte river in Denver overnight. Nearly an
        inch of rain... 0.98 inch... fell in the city.
      In 1944... a trace of rain fell on each day. This together
        with a trace of rain on the 4th and 30th was the only
        precipitation for the month. The total of a trace of
        precipitation for the month equaled the driest September
        on record first set in 1892.
      In 1994... unusually very warm weather resulted in three
        temperature records being equaled. High temperatures
        of 94 degrees on the 9th and 93 degrees on the 10th
        equaled record maximums for the dates. Low temperature
        of 63 degrees on the 9th equaled the record high minimum
        for the date.
10 in 1985... Golf Ball size hail was reported just east of Parker.
      In 1989... 3/4 inch diameter hail fell in Littleton. Heavy rain
        produced local flooding in Lakewood. The heavy rain caused
        the wall of a house to collapse.
      In 1993... thunderstorm winds downed power lines... which caused a
        power outage in Castle Rock.
