HUNTSVILLE, Ala. (WHNT) — The Tennessee Valley has been stuck in a recent pattern of daily rain and thunderstorm chances for the past week.
At times, the rain coverage has been widespread while at other times it has been isolated. The isolated coverage had led to some recording high rain totals while others saw little to no rain.
The strong south-southwest wind flow has acted as a continuous conveyor belt supplying warm air and deep tropical moisture into the Southeast region.
Above the surface, a dip in the jet stream to the west has acted as a boundary between the ridge over the region and a trough to the west. A boundary at the surface has remained nearly stationary over the area supporting the development of showers and storms.
With deep tropical moisture in place, torrential rainfall was possible with any shower or storm that developed.
Above is a look at the estimated rainfall totals across the Tennessee Valley over the last seven days. Areas highlighted in orange and red experienced the heaviest rain compared to the locations in green.
