In 1942...a strong thunderstorm produced hail and heavy rainfall in south Denver. Leaves were stripped from trees and heavy rain caused street flooding which halted traffic. Hail of unknown size reached a depth of 9 inches on the ground. In 1965...funnel clouds were observed to the south of Stapleton International Airport and in Jefferson County...15 miles southwest of the airport.

Hail to 3/4 inch in diameter fell in the Bear Valley area...12 miles south- southwest of Stapleton International Airport. Yet another tornado was sighted 10 miles northwest of the airport. Cloudbursts accompanied by hail battered areas of Arapahoe and Adams counties east of Denver...damaging ripening grain fields. At Lafayette...3.50 inches of rain fell in 30 minutes...causing some flooding. In 1982...numerous funnel clouds were observed over southwest metro Denver. Only one funnel touched down near the intersection of Jewell and Kipling. The tornado was on the ground for about 5 minutes and caused no damage except for uprooting some trees. In addition...thunderstorms produced heavy rain and hail in the foothills west of Denver. Over an inch of rain fell in a short time near Idaho Springs... causing Clear Creek to overflow its banks and flood a few low lying areas of the town. A few people were evacuated... and water and mud entered several stores. The heavy rain also washed out several roads. Hail piled up to a depth of 3 to 4 inches near Idaho Springs.
