NEW YORK (Reuters) - Sweeping storms threatening to unleash thunder, hail and tornadoes were expected to strike the Midwest and South on Tuesday, including towns still staggering from last week's deadly weather, forecasters said.
Extreme weather was expected to dump 6 to 12 inches of snow on Wisconsin, according to AccuWeather.com.
From Chicago south, severe thunderstorm warnings were underway, with some of the direst predictions for St. Louis, where "ping-pong sized hail" was expected, Accuweather.com meteorologists said.
Later in the day and overnight, powerful storms with lightning strikes, gusting winds and driving downpours were expected to unfold from the central Plains through the mid-Mississippi Valley, pushing east to the Ohio and Tennessee valley region.
"Once again we will be dealing with a triple threat of tornadoes, damaging winds and large hail," said forecasters on Weather.com.
Some of the twisters could touch down in the very same communities slammed by tornadoes last week, meteorologist Bill Deger said in a statement on AccuWeather.com. At least 45 people were killed across the southern United States, the highest storm death toll in more than three years.
"Unfortunately, some of those towns could be struck by strong storms this week," meteorologist Deger said. "Conditions could produce a 'few' tornadoes."
