Update on Georgia drought

In general, a one-category improvement was made to the drought depiction in areas which received 3 inches of rain or more during the past 1-2 weeks. This included eastern Arkansas, Louisiana, Mississippi, and significant portions of Alabama, Georgia, the Florida Panhandle, and the higher terrain of the Carolinas.

There was a 6% improvement or lessening of the portion of Georgia in the worst drought category and a 12% improvement in the next worse drought category. About 9 million Georgia residents remain under a drought classification.

December 2…UPDATED 5-day rainfall amount forecast map below:

Those who follow me on Twitter @MellishMeterWSB got the heads up on the change to cooler and wetter as far back as November 19th and 23rd.

Before the jet stream pattern change allowed the wet pattern to become established the drought had reached dire levels in much of the Southeast United States including Georgia as documented in previous posts.

Over the past three days 3-6 inch rainfall totals have been common across the area, well above normal for this time of year. The 2.32 inches of rain at the airport Wednesday Nov 30th was the [More]
