A line of thunderstorms, developing ahead of a cold front on the evening of May 1, moved into the the Adirondacks and Mohawk Valley from the western portion of New York.  The storms interacted with a strong low level jet and as a result, some of the cells produced severe weather, in the form of strong winds. The most significant wind damage came with a storm that moved across Montgomery County. This storm briefly spawned an F0 tornado near Tribes Hill, with winds estimated between 60 and 70 mph, at 520 PM. An eyewitness indicated that a visible twister took the tops off several pine trees in his yard as it moved east. The twister then turned to the north and damaged a nearby home, taking shingles off the roof and competely destroying the deck awning on the house. The tornado was only about 10 yards wide and the swath was about 50 yards in length. Five minutes later, the same storm produced a microburst in the town of Amsterdam, as another eyewitness reported hearing howling winds which collapsed a small garage. The wind with this downburst was estimated between 60 and 80 mph. Also in Montgomery County, numerous trees and wires were blown down in the towns of Nelliston and Canajoharie. At nearly the same time, this line of storms in Johnstown, Fulton County, was producing wind gusts strong enough to blow the roof off a porch and garage on  Rt. 67 near the Johnstown Airport. Scattered wind damage was reported in Herkimer County. A wire was blown down along Rt. 28 in Old Forge and shingles were blown off a home 4 miles south of Mohawk. In the town of Mohawk, a barn was completely destroyed. Over an hour later, a second storm brought more trees and wires down in the towns of West Winfield and Columbia Center. In Hamilton County, trees and wires came down on Rt. 28 at Long Lake Inlet. Finally, in Warren County, a tree was blown onto a car in Chestertown, damaging the vehicle.
