Thousands landed on the ground. The streets were literally covered with them. Swarms of grasshoppers were seen on each day. All gardens in the city were devastated...and in the countryside the grasshoppers were very destructive to ripened grain. On the 30th the grasshoppers were so numerous as to almost darken the sun. 22-24 In 1987...from the 22nd to the 24th...some locations in metro Denver had a total 3-day rainfall of 2 to 4 inches. Rainfall totaled 0.96 inch at Stapleton International Airport. 24 In 1880...a thunderstorm produced vivid lightning and heavy rainfall...which caused flooding over the eastern part of the city including the brick yards. There was no rainfall recorded in downtown Denver. In 1910...an apparent dry cold front caused a remarkable drop in temperature. From 3:00 PM until midnight the temperature fell from a high of 93 degrees to a low of 40 degrees. Northeast winds were sustained to 44 mph during the late afternoon.

Bear Creek rose above bankfull near Idledale with flood waters moving into southwest metro Denver. Mud and rock slides along Colorado Highway 74 west of Morrison were reported. The confluence of Cherry Creek and the South Platte River in downtown Denver also went out of its banks...flooding bike paths. Rainfall totaled 1.98 inches at Stapleton International Airport where light to moderate rain fell most of the day. Heavy rain and fog briefly reduced the surface visibility to 1 1/2 miles.
