A persistent broad upper trough will allow a frontal boundary to move very slowly or remain nearly stationary across the Tennessee Valley during much of the last week of July. A deep fetch of tropical moisture will continue to flow into the region ahead of the front, while repeated upper level disturbances help to initiate shower and thunderstorm development in the moist, unstable air just ahead of and along the front. The result will be periods of rainy and stormy weather for the Tennessee Valley for the week. Although periods of dry weather will be interspersed through the week, resulting rainfall totals may exceed several inches in some locations.This could result in localized flash flooding in urban or low-lying areas. The graphic above from the Hydrometeorological Prediction Center shows forecast 5-day rainfall amounts for the U.S.
