Changing seasons boost chance of rain

A total of 2 to 3 inches of rain in Northeast Georgia could fall in the next couple of days as a low-pressure system continues to move along the Appalachian Mountains.

The heavy rain could cause isolated flooding, according to the National Weather Service, which issued flash flood warnings Monday for Habersham and Rabun counties.

The forecast calls for a 90 percent chance of showers today, dropping to 40 percent tonight and 10 percent Wednesday.

As of 10 p.m., just over a quarter of an inch of rain had been recorded by the NWS at Lee Gilmer Memorial Airport in Gainesville, but the forecast called for 1 to 2 inches to fall Monday in the area, followed by another three-quarters to 1 inch today and a tenth to a quarter of an inch tonight.

“This is more of a fall and winter pattern,” said Steve Nelson, science operations officer at the NWS office in Peachtree City.

“We’ll go back to the cool, crisp mornings later this week, on Wednesday and Thursday.”

Nelson said “upward motion” of fronts moving through is what causes precipitation, and that’s why Northeast Georgia is likely to get this rainfall, unlike some earlier events that seemed to dodge the area.

“It depends on the path” of the storm, Nelson said. “We just got unlucky for a while there.”

He noted weather service forecasting models showed the remnants of what had been Hurricane Isaac coming to Georgia for several days, but by the time the storm got to the area, its energy had largely dissipated.

He said the lack of upward motion contributed to the area’s lack of rainfall during the summer.

What rain does fall won’t be enough to alleviate the dry conditions that have gripped much of the region, though, he said.

“It’s not as bad as in 2007 and 2008, and it’s a little bit better in Northeast Georgia,” Nelson said.

The forecast calls for partly cloudy skies Wednesday and Thursday and a mostly sunny Friday with highs in the mid- to upper-70s and lows climbing from 59 today to 62 on Friday.
