A strong cold front, supported aloft by a fasting-moving and deep upper level disturbance passing across the central Appalachians, produced a brief but potent round of high winds across the ridges and foothills of the Blue Ridge of southern Virginia.  Lowering inversion levels associated with clearing skies and subsidence in the approaching high pressure exposed the affected area to 50 knot winds aloft working their way to the surface.  Strongest winds occurred late in the evening of October 20th and during the early morning hours of the 21st.  By sunrise on the 21st, wind speeds were already quickly diminishing as the upper level support moved away to the east.
