The 2013 Fall (Sep/Oct/Nov) season ended with a wetter than normal November, due mainly to a strong gulf of mexico low that tracked across NE FL & SE GA just prior to Thanksgiving. But, overall due to the lack of any tropical cyclone activity the entire fall season generally ended with below normal precipitation totals across the region. Temperatures for the entire Fall season ended up close to normal values, but a few earlier than normal freeze events during the mid to late parts of November across the region did keep average temperatures below normal, mainly across the inland areas. The main story during the Fall season was the dominant Northeast Flow across the forecast area which resulted in windy conditions along the coast and poor boating conditions over the adjacent Atlantic coastal waters. The Northeast flow brought some rain bands into the coastal counties, but flooding rains did not occur and the main impacts were elevated tidal/water levels and beach erosion in some locations.
Normal Dates for First Freeze of the Season:
Jacksonville, FL: December 6th, THIS WINTER WAS November 28th (8 days early)
Gainesville, FL: December 4th, THIS WINTER WAS November 28th (6 days early)
Alma, GA: November 26th, THIS WINTER WAS November 13th (13 days early)
St. Simons Island, GA: December 20th, THIS WINTER WAS November 28th (22 days early)
November 2013 - Observed Precipitation Image #1 BELOW - Rainfall amounts were generally in the 2 to 4 inch range with isolated higher amounts around 6 inches in some NE FL locations.
November 2013 - Percent of Normal Precipitation Image #2 BELOW - Rainfall across the forecast area was generally well above normal for the month, mainly due to the Gulf of Mexico storm that crossed SE GA & NE FL on the 26th and daily rainfall records were set at Gainesville, FL and Alma & St. Simons Island, GA.
Fall (Sep/Oct/Nov) 2013 - Observed Precipitation Image #3 BELOW - Rainfall amounts were generally in the 4 to 8 inch range across inland SE GA and the Suwannee River Valley of North Florida, while 8 to 12 inch amounts were common along the coast and the rest of NE FL in the Northeast Flow pattern and where some fronts stalled during the fall months.
Fall (Sep/Oct/Nov) 2013 - Percent of Normal Precipitation Image #4 BELOW - As can be seen, almost all of the region experienced below normal precipitation values this Fall Season due to the lack of tropical cyclone activity even with the above normal precipitation amounts during the month of November. These rainfall departures have allowed portions of SE GA & NE FL to fall into D0 (Abnormally Dry) drought conditions as depicted by the U.S. Drought Monitor website.

Outlook for the Winter Months (Dec/Jan/Feb) from the CPC (Climate Prediction Center) website is calling for equal chances of above, below, or near normal temperatures across SE GA & NE FL, while there will be greater chances for the below normal precipitation values to continue, with further drought development possible.
