According to http://www.tornadohistoryproject.com/tornado/New-York/1983/5/2/table an outbreak that occurred in New York state that had just 6 tornadoes but all 6 were F-3's. Usually not many F-3s or higher in New York This seems pretty wierd. Pennsylvania had 2 F-2s with one traveling 10 miles and an f0. Pa's tornadoes were only about 30 yds wide and the 7 in Ohio on that day weren't wider than 100 yds. All the tornadoes in N.Y. were 150yds or wider. Three tornadoes in New York also had path lengths of 15 or more miles.
