Unsettled Weather Pattern Will Provide Waves of Rain/T-Storms to the Valley
A stagnant weather pattern is setting up across the Eastern United States and this is going to affect the Tennessee Valley by providing waves of rain and t-storms. Some of the waves will include some moderate to heavy rains. So what is exactly going on. The jetstream is dipping unusually far to the south for this time of year allowing fronts and waves of energy to traverse close to and in some cases through the Tennessee Valley. This mixed with seasonally warm and humid air south of the jetstream sets up the ingredients that mix together to fire thunderstorms.
In addition, the pattern is rather stagnant and that will allow for thunderstorm clusters to develop in the same locations and track in the same direction. This will provide the set up of some areas seeing repeat heavy rainfall which could become a flash flooding concern. Here is a look at the forecast rainfall through Thursday morning across the Southeast and the Tennessee Valley.
Notice the area of heaviest rains across the Lower Mississippi Valley and the Mid South, just to our west. This could shift over the Valley Thursday and Friday.
