(1:45PM - 6/24/19) A series of disturbances pushing through the region, along with a meandering frontal boundary, will bring the threat for repeated rounds of severe t'storms to the state through tonight.

Friday/night recap...
Two clusters of rain and t'storms moved across Central and Southern Illinois Friday morning into Friday evening, with a third across the same areas Friday night. The first two clusters brought widespread severe weather, in the form of wind and hail, to affected areas.

​​Saturday/night recap...
Two clusters of rain and t'storms moved across Central and Southern Illinois Saturday morning. Additional areas of rain and t'storms pushed across Northwest, Western and Southwest Illinois Saturday night. Only isolated severe t'storms were seen with activity Saturday morning through night.

Sunday/night recap...
Isolated to scattered showers and t’storms pushed across portions of Northern and Central Illinois Sunday morning through Sunday evening. The main focus was further south, where two clusters of rain and t’storms moved across Southern Illinois Sunday morning through Sunday evening. Scattered t’storms were severe with this activity, with all modes of severe weather having occurred.

​This afternoon-tonight...
Scattered showers and t’storms have been moving across much of Northern and Central Illinois this morning into early this afternoon. In the wake of this activity, additional scattered showers and t'storms have developed across Iowa, Wisconsin, Northwest and Western Illinois. This activity is expected to push east across a good portion of the state, this afternoon into tonight. An environment in place featuring low to moderate to instability, moderate moisture and decent shear is expected. This will promote an isolated severe t'storm threat across Northern and Central Illinois. Wind and hail will be the main threats.
