The wider storm

A weak frontal boundary located near the I-64 corridor provided the focus for repeated thunderstorm activity through the evening across several counties. A broad area of low pressure over the southeastern U.S. pulled very high moisture into the region allowing the slow-moving storms to be efficient rainfall producers. Rainfall amount were generally 2 to 4 inches, with isolated higher totals indicated by radar in the heavier cores occurring over a several hour period.
