Chance of showers may break summer pattern

POSTED: July 10, 2014 1:08 a.m.

A chance of thunderstorms today in Northeast Georgia may break this summer’s typical weather pattern.

The National Weather Service predicts a tenth to a quarter of an inch of rain, with higher amounts possible in thunderstorms.

“We basically have an upper level trough of low pressure moving along the Ohio and Tennessee valleys,” said Dan Darbe, senior meteorologist at the NWS office in Peachtree City. “We have an unstable air mass, and there’s a frontal boundary sagging into the state in the area of Gainesville, and that gives you a 40 to 50 percent chance” of thundershowers today, he said.

“(The Gainesville area) has a 40 to 50 percent chance of rain tomorrow, but just south of you, we’ve got a 60 percent chance.”

Darbe said the state is in a typical summer pattern where there’s a chance of thundershowers almost every day.
“We’re in that time of year where you can count on a 20 to 30 percent chance of a shower, but when you get pops up to 40, 50, 60 percent chances, you know something more is going on,” he said.

The forecast for the weekend calls for a return to the typical pattern, with a 20 percent chance of rain Friday and a 30 percent chance on Saturday and Sunday. Highs are expected to remain in the mid- to high 80s and lows are predicted to be in the upper 60s, creeping into the low 70s on Sunday.

Barring disruption from tropical weather systems, Darbe said the summer pattern should continue into September.

“September typically is the transition month,” he said.
