The main tornado threat was in parts of Missouri, Iowa, Kansas, and Nebraska, Marc Chenard, a National Weather Service meteorologist in College Park, Maryland, said in a phone interview.

Some 32 tornadoes have been reported in Kansas, Nebraska, Oklahoma, and Missouri since Tuesday, said meteorologist Patrick Marsh at the NWS’s storm prediction center in Norman, Oklahoma. No injuries had been reported, but images posted online by the NWS showed farm buildings flattened and a mobile home with its roof ripped off in north-central Kansas.

Tornado concerns were not as high on Thursday, forecasters said.

“You can’t rule one out today, but it’s not expecting to be a big time destructive tornado,” said NWS meteorologist Brandon Drake in Topeka, Kansas.

Further east, portions of southern New York state, northern Pennsylvania, and western New England could see wind gusts of up to 100 kilometres per hour, powerful enough to down trees, Chenard said.

Hail and wind threatened northeast Texas, southeast Oklahoma, and central Arkansas, Chenard added. In addition, Chenard said there was some threat of rain and flash flooding in parts of Iowa and Wisconsin on Thursday.
