After 11 consecutive months of drought in most of North and Central Georgia the April and May rains have brought a lot of relief.
1.6 million Georgia residents are under a drought classification, but most of those are in South Georgia, a big reversal from past months where the Mountains were in extreme drought or worse.
On a national basis the extent of drought is at it’s lowest since they started tracking it in 2000, at just 5% of the lower 48 states.
During the past 7 days in Georgia 3.4 Trillion gallons of rain has fallen, 4.9 the past 21 days, and over the past 30-days 5.5 Trillion gallons of rain has fallen over the state when you add it all up!
We started the week needing a lot more rain to eliminate drought entirely as seen in the map below:
We didn’t get it all but we got a lot.

Soil moisture levels can change rapidly week to week even while streams and lakes hold up. Drought tends to increase chances of intense heat in summer, and of course hotter weather tends to intensify drought. The opposite is also true.
The top soil moisture based analog model called the Constructed Analogue system CAS reveals the impact on temperature/rain in upcoming months below:
