The most arid year ever recorded for Atlanta was 1954, when only 31.80 inches of rain fell.
Meteorologists had feared this year would have even less rain, predicting that showers Sunday morning would taper off. But the rain continued long enough to raise the 2007 cumulative rainfall to 31.85 inches.
Dry weather was forecast for today.
More than one-third of the Southeast is in a severe drought. The Atlanta area, with a population of 5 million, is in the middle of the affected region, which includes most of Tennessee, Alabama, North and South Carolina, as well as parts of Kentucky and Virginia.
Hopes that Atlanta would escape a record-book entry this year rose as a parade of rainstorms began the week before Christmas. Atlanta got rain on 10 out of the last 12 days.
On Saturday morning, the 2007 cumulative rainfall total hit 30.5 inches, and an overnight soaking was on the way, fed by moisture from the Gulf of Mexico.
On Sunday morning, the weather service said it didn't look like enough would fall during the day to match the 1954 level, seeming to guarantee a new record. But by 6:45 p.m. Sunday, more than 1.25 inches had accumulated for the day.
Rainfall is measured at Hartsfield-Jackson Atlanta International Airport, just south of the city.
Rain has also been unusually sparse in other Georgia cities this year, including Athens, Columbia and Macon. However, each of those cities has seen worse years than 2007, said Stephen Konarik, a meteorologist for the National Weather Service.
The latest rain had only a small effect on the metropolitan area's main source of drinking water, Lake Lanier, where the receding water is exposing roads and the foundations of buildings submerged since the reservoir was created in the 1950s.
The water level in the reservoir stood at an all-time low of 1,050.79 feet on Wednesday. By 6 a.m. Sunday, it had risen only to 1,051.05 feet.
"What's falling now won't show up until tomorrow or the next day," said Rob Holland, a spokesman for the U.S. Army Corps of Engineers, which operates the reservoir.
"Anything that stops the level from falling is a good thing," he added. "But we'd like to get a whole lot more."
The lack of rainfall across the region has set off intense fighting between Georgia, Florida and Alabama over the federal government's management of water in the region.
Georgia Gov. Sonny Perdue has asked the federal government to release less water from its reservoirs, such as Lanier, but Alabama and Florida are concerned about how that would affect their supplies.
