With a slow moving cold front on the approach, Central Illinois was under the famous "See Text" setup. First cell popped along the I-72 corridor in Macon County before tracking slowly northeast. I positioned on its southern edge near Argenta, and noticed right above me was a weak broad circulation, with another weak concentrated circulation in the middle. Im assuming this would be the meso portion if there was one.
Later in the day an outflow boundary lifted north through Eastern Macon and Piatt Counties. A Shelf cloud was on the eastern part of the boundary while a Roll Cloud feature was back to the West. Which was another first for me this year....
This looked like the spot where the Roll Cloud & Shelf were joined. Notice the little Wall Cloud trying to form in the background, and possibly a small Funnel to the left of it.
The Roll Cloud feature back west didnt have the traditional rolling motion as it passed by. Its still considered an Arcus Roll Cloud since its detached from the actual storm base.
Wicked Outflow behind the Roll Cloud....
Wicked Outflow behind the Roll Cloud....
Followed it a lil further northeast before it fell apart.... 
I soon bailed on the northern portion and dropped south near the town of Macon. As the remaining cells moved in, a great lightning show was put on before these too gusted out. However before that happened, a large lowering formed & was creeping toward my direction.
As it got close it sort of lost steam, and this remaining cell soon gusted out marking the end to the storms....
Very Intense CG
