Portions of Illinois and Indiana look to get the worst of the weather today as a storm system pushes across the central United States. Conditions in eastern Iowa this afternoon are not terribly favorable for storm development. But later this afternoon and evening we could see an enhanced threat for supercells in portions of Illinois and stretching into Indiana. This is where the greatest threat for tornadoes will exist this afternoon and evening.
There is growing confidence this morning that the threat will push into the nighttime hours, with large hail and strong damaging winds the primary threat. Behind this storm system is much colder air that will limit our chances for thunderstorms until Friday. That’s when a storm system is expected to pass through the region, possibly bringing strong to severe storms to areas of Missouri, Iowa, Kansas, Nebraska and Oklahoma.
We’ll continue to monitor today’s threat for Illinois and Indiana and bring you updates as they come in.
