Off and on pattern of showers and storms continues
Through late Tuesday Evening, Lovell Field in Chattanooga had received 1.51" since Monday.
This pattern of off and on bands of showers and storms should continue through Wednesday. Even though the remnants of Alberto will move into the Ohio Valley Wednesday, the large circulation around it should keep a persistent southerly flow over the Tennessee Valley. This means that the pattern of off and on bands of showers and t-showers will still be possible. The main threat being heavy downpours at times and intermittent lightning. The ground remains saturated from previous rain, some these repeated downpours could quickly cause flooding.
Model data suggests that the upper flow over the Tennessee Valley should switch on Thursday from a southerly flow to a flow from the northwest. This could bring another round of showers and t-showers for the first half of Thursday, then possibly drier for the second half of the day and into Thursday Night.
The overall coverage of showers and storms could become even less for Friday and the weekend. Still slight chances each day, but much different than what we have had lately.
