A series of tornadoes hit Oklahoma Friday night, killing at least 13 people and leaving many more missing, without homes or stranded. Other storms and flooding also hit Arkansas and Missouri, and remnants of that severe weather moved east all the way to New England, where 19,000 are still without power on Monday morning.

Among the 13 killed in Oklahoma was a trio of well-known storm chasers. Tim Samaras, 55, a longtime, respected veteran in the field; his son, Paul, 24; and chase partner, Carl Young, 45, died while they were tracking a storm on Highway 40 just outside El Reno. Their vehicle, a white truck, was found there, having been crushed and mangled (see above). One of the bodies was still inside, while the other two were discovered a quarter mile away in either direction. The three starred in the Discovery channel program 'Storm Chasers.'

The storms this past weekend were not as powerful as the EF-5 tornado that demolished parts of Moore, Oklahoma, on May 20, but they came at a time when residents of the Sooner State were still beginning the long, post-catastrophic-weather recovery process.

Six people remain missing at this time, some of whom are believed to have taken shelter in storm drains.

In neighboring Arkansas, severe flooding led to the deaths of four people. And Missouri also suffered a forceful twister. Governor Jay Nixon said that three people had drowned, and that the tornado "caused dozens and dozens of houses to be literally blown up."

As the volatile weather system left the Midwest, it continued on a path east, sending at least one tornado as far as South Carolina. Torrential rains pounded the Northeast, canceling flights and knocking down telephone poles all across the region.
