Monday: 40 percent chance of showers and thunderstorms; high near 81
A strong storm is expected to move over the Hall County region Sunday and Monday, bringing the possibility of rain, hail and isolated flooding.
A slow-moving cold front will push through the area, approaching far Northwest Georgia early this morning, said Adam Baker, meteorologist with the National Weather Service in Peachtree City. It’s expected to reach the metro Atlanta area around noon.
“There’s a pretty good chance Sunday afternoon for showers and thunderstorms,” Baker said.
Hall County and the city of Gainesville could see about 1 inch to 1.5 inches of rainfall. But there could be isolated higher amounts if the rain falls quickly, Baker said.
The showers return two weeks after heavy storms caused floods in Flowery Branch and South Hall County. But the risk of such occurring again is small, Baker said.
“We’re not looking at any widespread flooding at the moment with this,” he said. “It’s not as potent of a system as what we’ve had in the past.”
The storm is forecasted to diminish toward the southeastern U.S. late Monday, the meteorologist said.
Baker said it should be nice midweek because of a weak high-pressure weather system behind the front and then more possibilities of afternoon showers as the weekend approaches. Thursday and Friday show a 30 percent chance of rain during the day.
The additional rain likely will raise the water level of Lake Lanier about three-tenths of a foot, said NWS Service Hydrologist Kent Frantz. That’s a good rise, he said.
“If we keep having an inch or 1.5 inches of rain a week over the Lake Lanier basin, that means that it’s (water level) going to fall very slowly during the summer,” Frantz said. “That’s actually a very good thing.”
The lake level is currently at 1,072 feet above sea level, which is 1 foot above full summer pool.
Lanier is in great shape heading into June. It‘s good that it’s the warm season because there’s a lot more runoff potential in winter when things are dormant, Frantz said.
“With the warmer temperatures, you’re going to have a lot more evaporation,” he said. “All the plants have fully matured now, so they’re using a lot of water.”
