The 8th of July was the last day of the 11 day heat wave. Temperatures reached on either side of 100 degrees across the southern lowlands.  This was the second consecutive day of triple digit maximum temperatures.
An east to west cold front was oriented across northern West Virginia.  A hot, moist, and moderately unstable environment existed south of the boundary.  Due to the heating, there was a steep low level lapse rate near the ground. Thunderstorms developed along the Route 50 corridor and moved south. Temperatures dropped rapidly at the onset of the storms.  For example, at the National Weather Service office in Charleston, the temperature dropped from 95 degrees to 73 degrees in 25 minutes.
Additional power outages occurred in areas still recovering from the late June derecho.  For example, outages in Kanawha County increased back to 25,000 customers.  Prior to these storms, the number of customers still without electricity had dropped to around 5,000.
This episode marked the end of a major federal disaster in West Virginia that was primarily for the events on the 29th of June and its aftermath.  See FEMA disaster 4071 for more details.
