International Airport. The strong winds downed trees and
power lines and damaged homes and cars. A Longmont man was
slightly injured... when a tree fell on top of his car.
In 1990... a slow moving thunderstorm over southwest Metro
Denver spawned an ominous looking funnel cloud near the
intersection of Sheridan Blvd. And U.S. Highway 285. The
Funnel cloud nearly touched down a few times before lifting
back into the main cloud. No damage was reported. Pea to
Marble size hail and 3/4 inch of rain fell over central and

backed up storm sewers. Thunderstorm rainfall totaled

Denver. Dime size hail was reported in many areas.
Straight-line winds from the thunderstorm... measured by a

of an apartment complex in Aurora. Heavy rain which
accompanied the winds caused major damage to the
apartments as well as the contents. Many trees... fences...
and power poles were knocked down by the strong winds.
Heavy rain flooded roadways in Denver and Aurora.

gusted to 44 mph at Stapleton International Airport where

mountains and Front Range eastern foothills. Golden
Gate Canyon received 6 inches of new snow with 5 inches
reported at both Nederland and Blackhawk. Thunderstorms
