West to northwest upper level flow will continue to keep a frequently stormy weather pattern for Alabama through at least Wednesday.
A MCS has organized near the Mississippi River late this afternoon. We expect it to hold together and move into the western counties later this evening.
This in combination with redevelopment of shower and thunderstorm activity expected this evening, heavy rain and flooding are possible.
A flash flood watch remains in effect for the Tennessee Valley counties of north Alabama through Tuesday.
We are looking for the possibility for some strong to marginally severe thunderstorms this evening and perhaps well into the night time hours.
The Storm Prediction Center has outline much of northwest Alabama for the standard risk of severe weather for tonight.
As has been the case for the last several systems, straight-line winds and large hail is the main threat. With recent heavy rains, flooding has become more of a threat as well.
We could very well have another round of stormy weather on Tuesday, as a larger scale upper level trough moves into the area.
