A strong low pressure center lifted northeast from the southern Plains into the Great Lakes.  A tight pressure gradient resulted in strong southerly winds ahead of an associated dry line and pressure trough which pushed eastward through the Tennessee Valley.  A broken line of showers and isolated thunderstorms developed along the dry line during the late morning hours, and swept rapidly east across the Tennessee Valley during the early afternoon hours.  Although a couple of reports of wind damage occurred with the showers and thunderstorms, the more prominent impact was due to damaging non-thunderstorm winds ahead of and immediately behind the dry line passage.  Numerous trees were blown down resulting in sporadic power outages.  There were also a few reports of minor roof damage and a couple of car accidents due to the high winds.
