Northwest Alabama is currently under a severe thunderstorm watch and we're seeing quite a few tornado warnings and thunderstorm warnings in Northern Mississippi. However, it still looks like we're going to see a weakening line of storms overnight. The tornado threat for Alabama (even for western counties) should remain low.
One of my favorite tools to use in the Energy Helicity Index or EHI. The index combines helicity (twist in the atmosphere) and instability. This system is very starved for instability here in Alabama. The EHI is peaking out mainly in Mississippi. I just don't see the atmosphere being primed enough here for anything widespread.
My main concern will be the Shoals, Marion, Lamar, and Pickens County through about 2am. The line should weaken quickly as it slides across the state. We'll keep you updated here on Fox 6.
