Trends are pointing toward increasing severe weather potential in northeast Nebraska into west-central Iowa this evening and potentially into the overnight hours. Large hail and damaging winds would be the primary hazards, but a tornado and some localized flooding cannot be ruled out.
There is potential for two rounds of severe weather Thursday—one in the morning and early afternoon and another during the evening and overnight. Large hail and damaging winds will be the main threats.
Another round of strong to severe storms is possible Friday evening and overnight. Potential will depend on what happens with any lingering storms during the morning hours. Keep an eye on the forecast.
