The next round of thunderstorms is moving in from the west and should reach the I-380 corridor in the next 2-3 hours. Coverage south of I-80 is also expected to increase through the evening ahead of the line. Primary threats right now include strong winds and hail up to quarter size.
Two rounds of severe thunderstorms are possible. The first is late this afternoon into tonight across southeast Iowa, far northeast Missouri into west central Illinois. The second will be tonight as a line of storms develops to our west and moves across the area. Have multiple way to receive warnings! When thunder roars go indoors.
Active pattern continues into tonight, with heavy rainfall possible in some of the passing storms. Areas along/north of I-80 have the best chance to see an inch or more of rainfall, with less expected south. There remains a low-end threat (15% chance) for flash flooding.
Severe thunderstorms are possible today. Here are some severe weather preparedness reminders.
