What the Heck Is This?

The green and brown is probably a pretty good giveaway, but do you know exactly what you're looking at?

On June 1 a thunderstorm in western Massachusetts developed into a supercell, which is science-speak for "trouble." Now can you guess?

See the full image, and more description, below.

The storm produced a tornado that carved a 39-mile (63-kilometer) track, which is what you see here. The image was taken from a satellite.

The Massachusetts tornado was about a half-mile wide at one point. It was rated an EF-3, with winds of up to 160 mph (257 kph).  There were two smaller tornadoes in the state that same day.

Isn't that rare for Massachusetts. Yes, but not unprecedented. In 1953, one of the deadliest tornadoes in U.S. history hit Worcester, Mass., killing 94 people.
