Widespread areas of rain and t’storm activity are expected across the state from Wednesday morning through Wednesday night. Of focus will be in the vicinity of the aforementioned frontal boundary in Southern Illinois, where a low coverage severe t’storm threat may exist.
•Thursday Morning – Thursday Night… As the next storm system passes through the region, a round or two of rain and t’storm activity will be likely across the state from Thursday morning and Thursday night. The first round of activity, likely to move across the state from Thursday morning through early Thursday evening, will pose some severe t’storm threat. Pending exact progression of this round of activity and potential for recovery in it’s wake, a second round of rain and t’storm activity may be possible across Northern and Central Illinois from later Thursday afternoon into Thursday night. This second round is more is question at this time, but should it come to fruition, would it carry some severe t’strom threat as well.
