Strong tornadoes and large hail are likely to strike the central and southern Plains region of the United States Monday evening, forecasters said.
Severe thunderstorms are expected to "explode rapidly into severe super cells across Kansas and Oklahoma," and could produce hail larger than baseballs, according to the forecast from the Storm Prediction Center in Norman, Oklahoma.
The forecast said the storms are most likely to hit northwest Arkansas, western Missouri, southwestern, central and eastern Kansas, and central and eastern Oklahoma between 5 p.m. and 9 p.m. CT.
"EF3-EF5 tornadoes are possible today," it said. EF5 - the highest level on the Enhanced Fujita Scale - indicates a tornado with winds over 200 mph.
"EF5 tornadoes can peel concrete and asphalt roads off the ground, and toss cars and trucks like toys," the forecast said.
