High winds associated with a fast moving cold front spread across the Urban Corridor and northeast plains of Colorado.  Several wind gusts to around 60 mph were observed as the cold front made its way across the region.  The cold front also spawned severe thunderstorms that preceded a potent spring snowstorm.  The severe weather included three tornadoes, damaging straightline winds and large hail, ranging in size from nickel to walnut size. The storms were most intense in and around Washington County where three weak tornadoes developed.  A severe thunderstorm produced damaging straightline winds which flipped a mobile home, blew the roof off a barn and downed numerous power lines.  A woman inside the home was not injured.  Half the town of Akron was left without power after six power poles were knocked down between Brush and Last Chance.  In Denver, the cold front produced a peak wind gust to 52 mph when it moved through Denver International Airport.  The strong winds toppled trees and caused several flight delays and cancellations.  In Longmont, the wind knocked over a tree which landed on to a house.
