A line of strong to severe storms is expected to develop along I-80 and to the north this evening from 9PM to 6AM, with the potential to deliver golf ball-sized hail, 60MPH wind gusts and heavy rainfall.

LINCOLN –  Some stream flooding is still expected to linger across parts of southeast Nebraska Saturday morning due to heavy rain that fell on Friday. Thunderstorms are forecast to develop this evening, and then increase in coverage for Saturday night

Some of these storms could become severe, with large hail and damaging winds. The highest chance of severe storms is across northeast Nebraska from about 10 p.m. Saturday evening until about 4 a.m. Sunday.  Storms could also produce locally heavy rain.

Severe storms are possible again from late Sunday afternoon into Sunday night, mostly across southeast Nebraska and southwest Iowa. The main hazards would be hail and damaging winds, but there is a small chance for a tornado or two.

Storms will again have the potential for heavy rain, and if that occurs in areas that are already wet from recent rain, then flooding could develop. Storm chances and potential for heavy rain linger into at least Monday for much of the area.

Additional thunderstorm activity is possible from Tuesday into Thursday, for at least parts of the area. Later outlooks will address the potential for severe storms in those periods.
