Severe storms are possible Saturday in the Southern Plains and the Great Lakes.

A stationary front draped across the central U.S. will continue to bring the threat for severe storms in the Southern and Central Plains, across the Texas Panhandle, western Oklahoma and much of Kansas on Saturday.

In the enhanced risk region the biggest threat will be large hail, but isolated tornadoes and damaging winds are expected. Flash flooding also remains a major concern, especially in Oklahoma and Kansas.

A second severe weather concern exists across parts of the Ohio Valley and Great Lakes, including Pittsburgh, Cleveland and Buffalo, New York. The main threat Saturday afternoon will be damaging winds, but hail or a brief tornado can’t be ruled out.
