The CG (cloud-to-ground) lightning strike here either penetrated or hit just behind the telltale signature of a microburst: a flared, curving foot at the bottom edge of a precipitation core. No reports of significant damage came from this event, as it struck in a rather dry river valley populated mainly by scorpions, sand burs, switchgrass, and scrub brush. However, wet microbursts like this can produce winds of over 100 mph—stronger than many weak tornadoes such as the one this storm produced several hours earlier.
