New England's not-so-rare Tornadoes

This past weekend two, that's right two, tornadoes struck the United States, but they didn't uproot any trailer homes in the lower Midwest. Instead they terrorized Brooklyn, and the Breezy Point neighborhood of Queens, both in New York City. Few injuries and no casualties were reported. Above is a picture from the Associated Press that shows the funnel cloud in Breezy Point. The tornadoes were part of a line of storms that swept across all of New York state this week.
According to the NBC article tornadoes were "once exceedingly rare in New York, but they have occurred with regularity in recent years." It is unclear if this increase in storms is attributed to global warming but there does seem to be a correlation between warmer temperatures and increased NY tornadoes.
CNN has an video of the formation of one of the tornadoes.
While the NYC tornadoes were the strangest of this weeks weather events, another tornado struck Oklahoma and killed 4 people.
