I opted to target just east of the Mississippi River along the surface warm front and east of the main surface cyclone. As the warm front lifted towards I-80 several rounds of convection occurred in the warm sector. Some late morning convection moved proximal to the warm front and may have laid down a boundary that later storms fed off of. An isolated cell formed south of Moline, IL along the eastern flanks of the MS River and tracked ENE near the front. It initially produced some good low-level convergence, rotation and brief funnels before getting interference from another cell as it tracked north of I-88. As I re-positioned north of Sterling-Rock Falls near a small town of Coletta, IL, I noticed an impending storm merger from the SSW. Within minutes after the two storms merged a large cone funnel appeared and then it produced a tornado for several minutes (1st photo). As the tornado lifted and the storm cycled, I re-positioned and caught a large fat white cone that was narrowing before it roped out (2nd and 3rd photos). I went north up into S WI as the warm front lifted north, but I wasn't able to confirm any more tornadoes with the ongoing storms. The storms occurred in a zone of rather favorable 0-3 km MLCAPE juxtaposed with a north moving surface warm front.
