The potential for very large hail, damaging winds, and even isolated tornadoes exists across Nebraska and Iowa today. A moderate risk has been issued from northern Kansas, through Nebraska and on into western Iowa. This is where the best potential will be for the very large hail, damaging winds and isolated tornadoes. Storms will form late this afternoon into the early evening hours and will be pushing their way to the east. Storms initially will be isolated before eventually merging together. As they push east, they will begin to merge and this will produce a widespread damaging wind threat.
Most of the state of Iowa is under that slight risk of severe weather (green shaded area) late this evening. The main risks in this slight risk will be large hail and damaging wind gusts. Another area of concern is the heavy rain that will be possible from these storms. The heaviest of the rain will fall across northwest Iowa and this is where three or more inches could fall. This would create a flash flooding concern. Remember don’t drown, turn around.
Our team is currently in central Nebraska getting into position for today. We will bring you that live video later on this afternoon. We will also bring you the very latest throughout the afternoon and this evening on Facebook and Twitter as well as right here at iowachase.com.
