More 'devastating' tornadoes possible on Tuesday
About 9.5 million people remained under the threat of more "large and devastating" tornadoes Tuesday as the storm system that devastated the suburbs of Oklahoma City moved east, forecasters warned.
Weather Channel meteorologist Kevin Roth said early Tuesday that the threat area appeared to be east and south of Oklahoma City.
"Tornadoes, damaging wind gusts and large hail are possible throughout the threat area," Roth said.
He added that cities including Dallas-Ft. Worth, Austin, San Antonio, Shreveport, Texarkana and Little Rock were among the cities "close to the the larger tornado threat."
"Another day of large and devastating tornadoes is possible this time from central/east Texas into central Arkansas," Roth said.
"Severe threat continues farther to the east Wednesday, although the overall severity appears to be lower."
Weather Channel forecaster Bill Karins told MSNBC that 9.5 million people lived in the area at most risk of more tornadoes. He said the likely pattern for twisters was the same as in recent days, with the biggest risk being in the late afternoon.
The National Weather Service said storms were expected Tuesday "from the Great Lakes across the Mississippi River Valley and into central Texas."
The agency issued a tornado watch late Monday for portions of east central Illinois, western and central Indiana, western Kentucky and southeast Missouri. The watch was in effect until 5 a.m. local time (6 a.m. ET).
According to Roth, severe storms appeared possible from southeast New York to east Maryland on Thursday.
He added: "An early look at Memorial Day Weekend shows that most of the country should be quiet. The stormiest weather appears to be across the Plains and Midwest with scattered showers and thunderstorms."
