This was the first day I worked at my job as a liquor store clerk. Cells fired across Iowa and into Illinois. After dark they congealed into an MCS and slunk south to the STL area. I remember a customer coming in remarking about the "light show" off to the north. After my shift (1:30 AM Saturday 6/19/2010.) I went on a night chase into Lincoln County to get some MCS action. I actually hate chasing MCS's as you're the one getting chased. Anyone remember that day and/or chased that day across IA or IL?
