August 2022 has been unusually wet in Metro Atlanta, with only 5 of the past 21 days registering dry weather at the Atlanta Airport.
An upper level trough developed over the Eastern U.S., including the state of Georgia, earlier this month and has not budged since then.
Upper level troughs are associated with areas of low pressure and unsettled weather at the surface, and indeed rain showers and storms have been in the forecast nearly all month long. The ECMWF Forecast 300 mbar level animation below shows the trough will be sticking around through this week, with little to no change in the upper level pattern expected.
As a result, more rain chances are in the forecast this week, though these rain chances indicate scattered off-and-on rain patterns as opposed to all day deluges.
Nevertheless, the average amount of rain for the month of August in Atlanta is 4.30 inches, but the city has received 5.60 inches of rain already with another week to go.
The data above is from the Atlanta Airport, which is the climatological reporting site for Metro Atlanta. Admittedly, not everywhere in Metro Atlanta and North Georgia has received the same amount of rain in the past month. In fact, east and northeast Georgia are still running a monthly rainfall deficit, with the city of Athens reporting a rainfall deficit of over half an inch.
