Rain may interfere with your weekend plans, but it should continue to help Lake Lanier.

“Comparing with what usually happens when we get 2 to 3 inches of rainfall, we could see Lake Lanier rise 2 to 3 feet,” said meteorologist George Wetzel of the National Weather Service in Peachtree City.

The lake was at 1,065.34 feet above sea level as of 10:15 p.m. Thursday night. Winter full pool is 1,070 feet.

The weather service predicts a 100 percent chance of precipitation in the form of showers today and tonight, and a 60 percent chance of showers Saturday. Temperatures will be in the 40s and 50s.

“North of the Atlanta metro through Saturday, the top end of the rainfall forecast is 3 inches,” Wetzel said.

A storm system that started over South Texas is going to become stationary over Central Georgia, he said.

“(Gainesville) could get 2 to 3 inches (of rain) overnight into Saturday,” Wetzel said.

The weather service has issued a flood watch for parts of North Georgia through Saturday afternoon. The watch is mainly south of a line from Cedartown to Cumming to Homer.

“Localized flash flooding will be possible if the heavy rain repeatedly moves over the same area,” the watch states.

Also, extensive street flooding could result if storm drains, ditches and low-lying areas become clogged with debris.

But North Georgia may be getting off easy, with Central and South Georgia expecting about twice as much rain, in the range of 4-6 inches.

Wetzel said most precipitation usually falls just north of a storm front, and as this one pushes south, a second wave of low pressure will boost rainfall totals in Central and South Georgia.

There could be some relief from the rainfall on Sunday, but more precipitation is in the forecast for the start of the workweek.

“The bright spot of our weekend is Sunday,” he said. “That could be our one sunny day, but then comes another 40 to 50 percent chance of rain.

“This is the time of year when we have active weather patterns,” Wetzel said, “Sometimes it’s in February, sometimes it’s in April.”
