Significant resurgence of rainfall occurring this evening
Just when it looked like we might be in for a few hours of no rain, showers have rapidly developed, spread out and increased in intensity in the same corridor from Roanoke south through Franklin County to Martinsville that has been frequented by bands of heavy rain through much of the day. The heaviest rain is occurring along the U.S. 220 corridor and moving northward, generally along the eastern side of the Blue Ridge. This is likely being caused by a combination of circulation from Fay's old center, now over eastern Kentucky, pulling a stream of moisture northward, and upslope effects of light southeast winds blowing uphill across the western Piedmont and onto the Blue Ridge. Radar estimates show rates of up to a half-inch an hour occurring. So it does look like the Roanoke Valley will be adding to its Fay-rain total this evening, possibly pushing our storm total over 4 inches. October 24-26 of last year was the last time we had more rain in a single event (6.10 inches).
