This will bring showers and thunderstorms across Southeast and South-Central Texas in addition to portions of the lower Mississippi Valley today. By Thursday, a surface low will lift northward into the Southeast, bringing additional rainfall to parts of the western Gulf Coast, lower Mississippi Valley northward into the Tennessee Valley.
