Overview

Strong gradient winds were observed across our region as surface low pressure deepened and moved north of the area. Wind gusts of 40 to 50 mph occurred through the day. During the afternoon, a line of thunderstorms formed from Arkansas into southeast Missouri and progressed eastward across the entire area into the early evening. This line produced scattered wind damage and minor flooding issues. Most locations received 1 to 2" of rain from this event, but there were some locally higher pockets over 2" in southeast Missouri and southern Illinois. Street flooding was most notable across Williamson County Illinois. Some power outages were observed as well including in the Paducah, Morganfield, and Henderson, KY areas as the line of storms moved through. There were 4 tornadoes that touched down in southern Illinois and southwest Indiana with this event, including an EF-1 that struck the town of Carmi.
