Heavy Rain in Martinsville (c) County, Virginia

The Martinsville COOP (MARV2) had 3.03 inches in the 24-hour period ending 700 AM EDT on June 8th, the highest ever for the date. The old record was 2.04 inches in 1934. It was also the 3rd highest daily amount in the month of June, with records dating back to 1931.

An unusual long-duration event occurred June 7-11 as a very slow-moving upper trough and surface high across New England combined to produce several days of cool-air damming and persistent rainfall along the frontal boundary and in orographically favored areas of the Blue Ridge. Rainfall was focused over western Franklin and eastern Floyd counties where rain gauges showed 3 to 4.5 inches in the 24-hour period ending at 0800 EDT on June 8th. The rain continued much of the 8th with an additional 2 to 4 inches across that same area. Embedded thunderstorms over eastern Patrick County dropped 2 to 5 inches in several hours in the early afternoon of the 8th.
