After a relatively dry work week, heavy rain will return to Metro Atlanta this weekend, just in time for Football Friday and Game Day Saturday.
A cut-off low over the Gulf of Mexico will produce unsettled weather over the Southeast, and it will tap into the deep Gulf moisture over the region.
The animation below illustrates the forecast vorticity over the Gulf of Mexico -- large amounts of positive vorticity advection (PVA) indicate upward motion in the atmosphere, which generates rain and thunderstorms.
As a result, waves of torrential rainfall are expected beginning Friday afternoon through Sunday evening. The animation below illustrates the waves of precipitation that is anticipated to move through the Southeast, including Metro Atlanta. Areas of yellow and orange denote heavy precipitation and thunderstorms.
As much as 1-3 inches of rainfall is possible Friday afternoon through Sunday evening. While this rainfall amount seems relatively low, it will be falling over an area that has received copious amounts of rain over the Labor Day holiday weekend on top of an already wet August 2022 overall.
