The National Weather Service said a “multitude of hazardous weather” would impact the U.S. over the next several days — from thunderstorms and potentially baseball-sized hail on the Plains, to heavy mountain snow in the West and dangerous heat in the South.

Forecasters say more tornadoes could center around eastern Oklahoma on Monday and Alabama, Mississippi and Tennessee are under the highest risk on Tuesday.

Meteorologists with the NWS Paducah office have also confirmed several tornadoes in its region the afternoon and evening of May 16. Three tornadoes impacted western Kentucky, including an EF-3 tornado in Morganfield with winds of 155 mph, an EF-2 tornado in Allegre and an EF-2 tornado in Casky.
