A bridge on Highway 11 south of Sherman suffered extensive damage.

The wider storm

An upper level low lingered in the area for several days. An unstable atmosphere helped kick off several rounds of showers and storms. Boundaries helped focus rainfall totals over the same areas....leading to flash flooding.

Began near Collinsville (33.5700, -96.9200).
