EURO Precipitable Water (Available Moisture)

Following a dry and mild week across the South overall, another storm will bring rain and even heavy rain to some locations this weekend. The storm that’s bringing rain and snow to the Northwest will move across the United States/Canada border, and the cold front associated with it will draw up moisture and bring rain to much of the Eastern US. In the Southeast, along with rain developing ahead of the cold front, the potential development of a very weak low pressure in the northeastern Gulf of Mexico may allow for extra forcing and lift, therefore leading to heavier rain.

The rain will begin on Saturday across the Southeast. Even a few rain showers may develop late in the day Friday as warm, moist air gets lifted by the cold front and therefore leads to showers. Saturday morning is going to be very wet with a moderate to perhaps heavy rain stretching from central Alabama through central and southern Mississippi, and into southern Louisiana as a direct tap of tropical moisture sis established. There will also be a line of showers ahead of the cold front that slowly moves south and east, spanning from the Tennessee and Mid-Mississippi Valleys through the ArkLaTex and southward through the Texas Gulf Coast. In the afternoon, the widespread rain will persist across similar areas in the Deep South while expanding into northern Georgia and possibly the western Carolinas. Showers and thunderstorms will also continues to slowly work south and east before decreasing in intensity Saturday night.

Overnight Saturday, the widespread rain will move into much of Alabama, Georgia, the Florida Panhandle, and the Carolinas. The heaviest of rain will likely be focused from Mobile, AL through Tallahassee, FL and northward to the Macon, GA area. Meanwhile to the north and west, the rain will begin to clear out of the Tennessee and Mid-Mississippi Valleys as the cold front pushes through, ushering in cooler air.

Then on Sunday, the rain will become confined to really areas east of the Appalachians. This includes the Carolinas, Alabama, Georgia, and the Florida Panhandle. These areas can expect periods of rain throughout the day while much of the Florida Peninsula experience scattered showers and thunderstorms at times. By the afternoon, the rain will clear out of Alabama due to the passage of the cold front, and by the middle of Sunday night, most of the Southeast will dry out as a new air mass builds in.
