If it seems unusually quiet indoors over the next few days, that may be because your air conditioner isn’t running.
At least, it may not be running as much as usual, as temperatures are expected to fall toward a high of 70 degrees, according to the National Weather Service.
The forecast calls for a high today near 76, down sharply from Wednesday. The cooler-than-normal temperatures are expected to linger until Monday.
“For Northeast Georgia, highs (in mid-August) should be in the mid- to upper 80s, maybe around 90” said weather service meteorologist Verona Murrell. “So that (forecast is) quite a difference from the typical (ones).”
A combination of factors is causing the relatively mild midsummer temperatures, she said.
“We’re expecting a northeasterly cold air damming event that pushes the clouds up against the higher elevations,” Murrell said. “You don’t get much warming” in those conditions, and clouds and rain are in the forecast as well, to add to the cooling effect, she said.
Highs should remain in the 70s through the weekend, the weather service forecasts. Lows are expected to be in the mid-60s.
“It starts warming up again toward Monday,” Murrell said.
Also, “we’re looking at a long period of rain,” she said.
The weather service predicts a 50 percent chance of rain today, rising to 60 percent tonight and Friday before dropping back to 50 percent for Friday night. The chance of precipitation goes up to 80 percent on Saturday, then drops to 60 percent for Saturday night and Sunday.
The weather service is watching some tropical moisture, which could add to the rainfall, Murrell said.
Flooding is probable, she said, but the weather service needs more data before issuing any watches or warnings.
“We have to see how things set up, if the storms train up over one another and if there’s heavier convection in some of the storms.”
