UPDATE: OKLAHOMA CITY (WKOW) – A storm system that produced a deadly tornado in Oklahoma has moved into the central plains and remains a threat.
Bill Bunting, chief of operations at the National Weather Service's Storm Predictions Center in Norman, said the greatest threat appears to be from northeastern Iowa to southeastern Minnesota and into western and central Wisconsin.
On Sunday, Bunting said that the storm system was centered over Nebraska. The storm has weakened a little bit but it could still produce another round of tornadoes across the nation's midsection.
The system produced a deadly tornado in northwestern Oklahoma early Sunday morning that left five people dead.
OKLAHOMA CITY (WKOW) – Authorities say search and rescue crews are combing through northwest Oklahoma after a tornado left five people dead and several injured.
The tornado hit just after midnight on Sunday around the towns of Woodward and Tangier. Woodward Mayor Roscoe Hill said sirens apparently were not sounding though they had worked for earlier storms.
Oklahoma Department of Emergency Management spokeswoman Keli Cain said early Sunday that state medical examiner's office had confirmed the fatalities in the Woodward area.
The National Weather Service says more than 100 tornadoes had been reported across the Midwest and Plains by early Sunday.
Forecasters continue to warn that the possibility of "life threatening" severe weather still exists today across the Midwest and Plains. Strong thunderstorms are expected as far east as Michigan, but forecasters say the storm system is weakening and additional tornadoes are unlikely.
In the western Iowa town of Thurman, piles of toppled trees lined the streets in front of homes with missing walls and roofs. Neighbors said they're amazed no one was seriously injured.
Storms were reported yesterday in Kansas, Iowa, Nebraska and Oklahoma.
