Rain, floods, more tornadoes set for storm-battered mid-US

Conditions are favorable for the development of tornados in Kansas, Oklahoma and surrounding states. Isolated tornadoes are also possible in the Northeast. The Weather Channel's Chris Warren reports.

More severe weather was forecast for the nation’s storm-battered midsection Thursday, including the threat of tornadoes in the Oklahoma City area hit by last week’s deadly twisters.

Heavy rain and flooding is likely from the eastern Plains to the lower Great Lakes, Weather Channel meteorologist Kevin Roth said.

Hail and damaging winds resulted in more than 250 storm reports by the end of Wednesday, according to weather.com, as a “multi-day severe weather outbreak” continued to bring misery to the Plains.

A preliminary 19 tornadoes were reported in four different states -- Texas, Kansas, Nebraska, and Iowa -- on Wednesday, weather.com said.

At least 21 tornadoes touched down Tuesday, injuring at least seven people in three states.

The storm system responsible is forecast to move slowly eastward through the weekend, Roth said.

Areas likely to be worst hit include Minneapolis, which is set for strong evening thunderstorms, and Kansas City, Roth said.

In Oklahoma City, where 24 people were killed by twisters last week, severe storms are likely again Thursday evening, bringing the threat of more tornadoes.

Thursday’s storm system will reach the Northeast and Mid-Atlantic areas on Sunday, bringing showers, thunderstorms and cooler temperatures, Roth said.

Torrential rain and localized flooding is possible in parts of Florida over the coming days.
