Very strong winds preceding a cold front swept across the Front Range Foothills, Urban Corridor and Northeast Plains.  Peak wind gusts ranged from 60 to 85 mph.  Numerous accidents were reported along Interstate 70 between Cedar Point and Limon.  The strong crosswinds blew six semi-trucks and an RV on their sides; causing minor injuries and the temporary closure of the interstate.
Numerous power poles were snapped across parts of Lincoln and Weld Counties resulting in several road closures.  In Arriba, a roof was blown off a building.  In Agate, a wood, metal and brick structure collapsed with minor damage to the adjacent post office.  In Aurora, roof damage was reported at Rangeview High School.  Strong winds downed trees and power lines in Conifer and Denver causing several brief outages.  Downed power lines caused several cars to catch fire in the vicinity of 1590 Cook St in Denver.  Finally, a severe thunderstorm produced large hail, up to quarter size, near Sterling Reservoir.
