A line of strong to severe storms will develop across northeast Nebraska late in the day Tuesday and will enter into northwest Iowa after dark. This line of storms will pose mainly a damaging wind and large hail threat, however, an isolated tornado or two can not be ruled out.
Storms will develop in the enhanced risk region of northeast Nebraska after 4pm. Storms initially will be isolated and will be capable of producing all modes of severe weather. Storms will eventually grow upscale and move to the northeast. Once this occurs, the main threat will transition over to a damaging wind threat.
Storms will begin to enter into northwest Iowa after 8pm and will continue to the east/northeast across northern Iowa. Storms will eventually clear out of the state by 9pm Wednesday morning. If you live in the enhanced risk region, all modes of severe weather will be possible, which includes; significant hail up to golf ball or larger, damaging winds up to 70 mph and even tornadoes. Please be prepared and be ready for severe weather potential Tuesday afternoon and evening.
