CLANTON – Monday, 1:45 pm August 7, 2023
A very volatile severe weather event is unfolding. A line of intense thunderstorms has entered the northwest portions of the state as of 1 pm. In addition, clusters of thunderstorms are forming near and north of I-59 and any of these storms could quickly become severe.
The potential exists for pockets of widespread wind damage up to 70 mph, very large hail, torrential rainfall for much of the state through this evening. In addition, a couple of tornadoes are possible, especially in the SPC Enhanced Risk area as shown in the graphic above.
In addition, high heat and humidity will result in Heat Index values from 107-113 into this evening, prompting Excessive Heat Warnings and a Heat Advisory, which will likely continue throughout much of the week for portions of the state.
Prolonged exposure can increase your risk of heat related illnesses, such as heat stroke. If you must be outside, take frequent breaks and drink plenty of water.
On Tuesday, another MCS will move into the state by late morning through early evening. A few damaging wind gusts and hail are the threats. As has been stated several times in previous briefings, the predictability for timing and exact locations for MCS activity beyond 12 hours is low due to the relatively small size of these systems. Potential changes to this forecast may occur in later updates.
On Wednesday, yet another MCS is forecast during the afternoon and evening hours with a damaging wind threat. Unfortunately, the unsettled pattern continues from Thursday into the weekend with the potential for additional severe weather each day.
