Metro Atlanta Rain Totals Last Week

I received a nice note from a blog reader in northeast Cobb county reporting that they got quite a bit of rain over the last week. He estimated that about ten inches had fallen where he lives. Well, 10 inches would be quite a lot of rainfall — more like what we would see as the result of tropical weather, and looking at some of the estimated precipitation data from the weather service, they don’t have anything like that reported. That being said, it looks like Marietta did have the highest amount of rainfall over the last week.

From July 7th through yesterday, here are the rainfall totals for some metro Atlanta locations:
Athens: 2.79 inches
Atlanta: 3.91 inches
Gainesville: 1.92 inches
Marietta: 4.18 inches
Chamblee (Peachtree DeKalb): 2 inches
West Atlanta (Charlie Brown): 1.83 inches

For the month of July so far, here are some totals:
Athens: 3.31 inches
Atlanta: 4.82 inches
Allatoona Dam: 6.07 inches
Alpharetta: 3.1 inches
Ball Ground: 5.55 inches
Carrollton: 1.52 inches
Gainesville: 1.92 inches
Helen: 4.45 Inches

Here in Lawrenceville, I’ve recorded 2.03 inches for July to date. So, it’s fair to assume that locations in the northwest got more rain than did those on the east or south of Atlanta. July is typically the rainiest month on average for Atlanta, with 5.12 inches in a typical year. However, the capriciousness of thunderstorms means that rainfall amounts can vary widely, even over a relatively small area.

We probably won’t have to worry too much about rain for the next few days. Behind the cold front that pushed through last night is much drier air, and you’ll see low humidity and dew points for the next few days. That also means cooler evening temperatures, and no weather problems for the primary election on Tuesday.
