Yet another very active 24 hours (and beyond) is in store for the state.
Wave one will bring a cluster of storms moving from west to east across Alabama this morning. The main threat area will generally be across the western half of the state for the remainder of this morning. Damaging wind gusts and hail are the main threats.
This will be followed by a second wave that is difficult to pinpoint threat locations, as storm development will depend upon where boundaries are located that are left behind by wave one. These boundaries will aid in thunderstorm development later today. For now, an almost statewide threat area is defined, and especially across the southern half of the state from 12 pm – 7 pm. Damaging wind gusts and very large hail are the main threats, but a tornado or two are also possible.
The third and likely most potent wave will enter northwest Alabama between 8 pm – 10 pm this evening and move southeastward, exiting the southeastern sections around 7 am Monday. This wave is forecast to contain a large line/clusters of storms, with damaging wind gusts up to 70 mph and very large hail.
On Monday, scattered to numerous showers and thunderstorms are forecast to develop statewide, with a few damaging wind gusts and hail from 1 pm – 9 pm. The greatest risk of severe weather will occur across the southern half of the state where the atmosphere will be most unstable.
On Tuesday, the state will finally start to see an overall decrease in severe storms, but several storms could produce gusty winds from 40-60 mph.
