with locally higher amounts, are expected in northern Alabama and
the Tennessee Valley into the Mid-Atlantic through the weekend.
There is a potential for 3 to 6 inches in the Southern to Central
Appalachians, which could lead to flash, urban, small stream, along
with isolated minor river flooding.
TORNADOES: A few tornadoes are possible across parts of Alabama,
the Florida Panhandle, and western Georgia through early tonight.
