Iowa’s rain chances increase into Saturday evening and there is potential for early Sunday morning severe weather continuing into Mother’s Day afternoon with areas of concern along the Iowa/Minnesota state line and in Western Iowa.

Southwest and west-central portions of Nebraska are areas of concern beginning with thunderstorms. Severe storms also could develop along the Nebraska/Iowa state line Saturday night.

Sunday brings possible isolated tornadoes from extreme eastern Nebraska into southwest Iowa Sunday afternoon. A winter weather advisory is issued for Sheridan County on northwest Nebraska, which could get up to 5 inches of snow Saturday night continuing into Sunday.
