The first damage was noted along Ridgewood Court and 38th Street, where multiple trees had large branches broken. The tornado moved generally to the southeast, entering Downers Grove near Cumnor Road and 39th Street, where damage was noted to numerous trees. Minor damage was also noted to the cupola of a nearby residence. The tornado moved through the Longmeadow neighborhood, continuing to damage numerous trees. In some areas, the most significant tree damage was noted just above roof level. The tornado slightly intensified near 41st Street and Williams Street, where a few homes had minor roofing damage and numerous trees had large branches broken. Debris from damaged fences was blown in a somewhat convergent pattern toward 41st Street on opposite sides of the street. The tornado appeared to dissipate just southeast of this area as it approached Westmont. The peak wind of this tornado was estimated at 80 mph. .DuPage County Straight-Line Winds... An NWS storm survey indicated that a corridor of straight-line wind damage occurred in the Glen Ellyn, Downers Grove, Oak Brook, Westmont, and Clarendon Hills areas. Straight-line winds initially occurred along two corridors approximately one half mile in width, the northern area beginning just south of Glen Ellyn and the southern area beginning south of Morton Arboretum. To the east, these areas of wind damage merged in northeastern Downers Grove and reached a peak width of approximately 1.5 miles. As the winds moved to the east, the width narrowed slightly as peak winds decreased, with straight line wind damage appearing to end near Clarendon Hills. Most damage was confined to trees, including widespread breaking of twigs and small branches with isolated large branches broken, consistent with peak wind gusts up to 60 mph. A few smaller areas experienced more significant wind damage, including a large uprooted tree and numerous large branches broken in the Orchard Brook neighborhood of Downers Grove, damage to a church and numerous large branches broken near Downers Grove North High School, damage to utility poles and large branches broken in the Fairview Avenue subdivision of Downers Grove, and damage to a utility pole and large branches broken in the Blackhawk Heights subdivision of Westmont and also nearby western Clarendon Hills. Damage in each of these isolated, narrow corridors was consistent with peak wind gusts up to 70-75 mph. Embedded in the northern edge of this corridor of straight-line winds was a brief, narrow tornado that impacted areas near the edges of Oak Brook, Downers Grove, and Westmont. However, the overwhelming majority of damage in the surveyed area was due to straight-line winds. && EF Scale: The Enhanced Fujita Scale classifies tornadoes into the following categories: EF0.....65 to 85 mph EF1.....86 to 110 mph EF2.....111 to 135 mph EF3.....136 to 165 mph EF4.....166 to 200 mph EF5.....>200 mph NOTE: The information in this statement is preliminary and subject to change pending final review of the events and publication in NWS Storm Data. $$ NWS Chicago
