The wider storm

A backbuilding cluster of thunderstorms near the MO/IA border slowly sagged southward during the afternoon hours on August 12th. An additional cluster of thunderstorms congealed across northeastern Kansas into north-central Missouri and merged into the backbuilding cluster. These thunderstorms developed ahead of a synoptic cold front. As these storms moved southeast across the region, some became severe and produced widespread damaging winds.
