After a morning round of storms on Friday, additional showers and storms will develop during the early evening into the overnight hours, some of which could be strong to severe. Primary hazards include damaging winds, hail, and frequent lightning, but a few brief tornadoes cannot be ruled out.
Multiple rounds of storms through Saturday morning pose a localized flooding threat across the region, but primarily in eastern Iowa. Swaths of 2+ inches of rain are possible with rainfall rates exceeding an inch per hour at times. Remember to never drive or walk through flooded areas!
