January 2012 Climate Summary - Georgia
Prepared by Pam Knox, University of Georgia climatologist
Cold temperatures and heavy snow crippled northern parts of Georgia during January 2011. In spite of heavier than normal snowfall, the precipitation amounts across the state were below normal, increasing drought conditions across the state.
Temperatures across the state continued to be significantly below normal everywhere in Georgia this month. In Atlanta, the monthly average temperature was 40.2 degrees F (2.5 degrees below normal), in Athens 39.7 degrees (2.5 degrees below normal), Columbus 43.6 (3.2 degrees below normal), Macon 42.0 (3.5 below normal), Savannah 45.1 (4.1 below normal), Brunswick 49.1 (2.6 below normal), Alma 44.9 (6.8 below normal), Valdosta 47.3 (2.6 below normal) and Augusta 41.7 (3.1 below normal).
If colder than normal temperatures continue into February, this winter could be close to setting records for the coldest winter ever in some parts of Georgia.
Record low temperatures were set at Macon, Savannah and Alma on January 14. Macon reported 16 F, breaking the old record of 19 F set in 1970 and Savannah and Alma reported 18 F, surpassing the old records of 20 F set at both locations in 1964.
Dry conditions from December continued into January, leading to an increase in the severity and expanse of drought across Georgia this month. The only area that was above average in rainfall was a small area in the far southeastern part of the state.
The highest monthly total precipitation from National Weather Service reporting stations was 4.93 inches in Valdosta (1.44 inches below normal) and the lowest was in Augusta at 2.11 inches (2.39 below normal). Athens received 3.32 inches (1.37 below normal), Atlanta 2.63 inches (2.40 inches below normal), Alma 2.29 (2.54 below normal), Columbus 3.15 (1.63 below normal), Macon 2.79 (2.21 below normal), Savannah 2.46 (1.49 below normal) and Brunswick 3.10 (0.76 inches below normal).
Athens reported a daily record snowfall of 4.3 inches on January 10, surpassing the old record of a trace observed in several previous years. The storm total of 8.8 inches on January 9-10 set an all-time record for a 24-hour snow total in Athens. Brunswick also set a daily precipitation record of 1.96 inches of rain on the 25th, passing the old record of 1.68 inches set in 1966.
The highest single-day rainfall from CoCoRaHS stations was 2.41 inches near Lafayette in Walker County on January 1. An observer in St. Mary's in Camden County observed 2.30 inches on January 26. The highest monthly total precipitation of 6.72 inches was measured at Lake Park near Valdosta in Lowndes County. The highest monthly snowfall measured by a CoCoRaHS observer in January was 14.4 inches in Blue Ridge in Fannin County, followed by 11.2 inches in Ringgold in Catoosa County.
There were no official reports of severe weather in Georgia in January. However, a massive oak tree was blown down by the wind on January 26 in Athens near the Five Points intersection, injuring one pedestrian and cutting off power to about 800 people for several hours, including parts of the University of Georgia campus.
The extensive winter storm of January 9-10 caused widespread school and business closings and multiple traffic accidents as well as scattered power outages across north Georgia. Thousands of flights were canceled across the eastern US. Several thousand people were affected by the lack of power, but most power was restored relatively quickly. It was estimated that $300 million dollars was lost in unrecoverable retail sales by businesses and restaurants due to the lengthy clean-up period. Some schools in north Georgia were closed for an entire week due to the lack of snow removal equipment and the frigid temperatures following the snow and ice storm, which hampered clean-up efforts and melting.
The US Department of Agriculture reported that pastures continued to be in very poor to fair condition across most of the state this month. Harvest of soybeans, cotton, sorghum, pecans and peanuts continued to wrap up, and Vidalia onion shoots were transplanted as expected.
