(12:45AM - 6/16/19) A disturbance pushing through the region, along with a lingering front, will bring a severe t'storm threat to portions of the state through Monday.

Tonight...
Areas of showers and t’storms have been ongoing across much of the state tonight. Some of this activity across Central and Southern Illinois has been severe, with all modes of severe weather having occurred. Areas of showers and t'storms will persist across the state overnight, with a continued isolated to widely scattered severe t'storm threat across portions of Central and Southern Illinois.

Sunday into Sunday night...
A few areas of isolated showers and t’storms will be ongoing across portions of Northern and Southern Illinois Sunday morning. In the wake of this early activity, development of new scattered showers and t’storms is likely during the afternoon across portions of Missouri, Arkansas, Central and Southern Illinois, in the vicinity of a front across the area. This activity will push east-northeastward across portions of Central and much of Southern Illinois into Sunday night. An environment in place featuring low instability, good moisture, and decent shear will be in place. This will help support an isolated severe t'storm threat across portions of Central and much of Southern Illinois. Wind and hail will be the main threats.
