Heavy rain to march across the South Monday through Friday.

Starting Monday and lasting through Friday, rain will march across the south. Starting on Monday, much of West and parts of Central Texas will see rain, which will be steadily increasing in intensity and the system gains moisture from the Gulf of Mexico. By Tuesday, a combination of Pacific and Gulf of Mexico moisture will cause a large band of heavy rain to form over much of Texas and parts of the ArkLaTex. Wednesday this band will move farther east losing some of the pacific moisture but gaining Atlantic Moisture, the band will be over the ArkLaTex and over the Mississippi Delta at this point. On Thursday, the band will cover much of Mississippi and Alabama losing much of its Pacific moisture, the band will be a bit lighter but still covering most of the area. On Friday it will move over the rest of Alabama and parts of the FL Panhandle, finally lifting out of the area giving way to cool temperatures and sunshine.
