A line of thunderstorms developed along a pre-frontal trough and moved across the entire region from west to east from mid-morning through early afternoon. The thunderstorm winds downed trees and power lines as the fast moving line swept across the area. Power poles were snapped in some cases and power outages were reported throughout the area. Utilities reported tens of thousands of customers without power. In the City of Buffalo, a funnel cloud was sighted although a damage survey proved that damage to several buildings on the west side of the city was caused by straight-line winds. In some locations roads were blocked by downed trees. In Cheektowaga Town Park, twenty to thirty large trees were blown down. In Marilla, in addition to tree damage, a trailer was blown onto its side and into some trees.
