A new tornado watch has been issued for southwestern Kansas and western Oklahoma until 10 p.m. CDT. According to the Storm Prediction Center, a few tornadoes are possible and a couple could be intense (EF3 or stronger). Widespread large hail (up to 3 inches in diameter) and damaging wind gusts up to 70 mph are all possible.

National Weather Service officials place most of KMAland in a slight risk for severe weather, with an enhanced risk south of the Iowa-Missouri border. While the full gamut of severe weather is possible, Weathereye Meteorologist Kara Foster says hail is the main threat.

The NWS confirmed a tornado struck southwest of Arnett. Residents were warned to take shelter. The agency said "risk for tornadoes and extremely large (3+) inch hail continues north and east of Harmon." Tornado warnings also have been issued for the towns of Sharon and Harmon until 7 p.m. May 18.

Storms Friday afternoon tore roofs off buildings, ripped bricks off of siding and downed trees and power lines.

St. Louis Mayor Cara Spencer said five people died, 38 were injured and more than 5,000 homes were affected in her city after severe storms that hit parts of the U.S.

The National Weather Service has confirmed several EF4-strength tornadoes in outbreaks of severe weather this month, the most since 1997.
