Atlanta, Georgia – A push of Arctic air is expected to reach Georgia between Jan. 18 and Jan. 22, bringing a noticeable shift toward colder-than-normal temperatures as a clipper system helps reinforce a broader pattern change across the eastern United States.
According to the Climate Prediction Center’s 6–10 day temperature outlook, Georgia is favored to experience below-normal temperatures during this period as a deep upper-level trough settles over the eastern half of the country. The colder pattern follows the breakdown of a recent mild stretch, driven by strong ridging across the western U.S. and Alaska that allows colder air to spill southward into the Southeast.
Daytime high temperatures are expected to run several degrees below mid-January averages, with overnight lows dropping more sharply across northern and inland portions of the state. While southern and coastal areas may see some moderation at times, increasing winds behind the passing clipper system could lead to chillier morning conditions, particularly during overnight and early morning hours.
At this time, precipitation chances are expected to remain near normal for this time of year. Forecast guidance does not show a strong signal for widespread rain or winter weather during the Jan. 18–22 window, as the incoming Arctic air mass is expected to be relatively dry. Any precipitation that does occur would likely be light and brief, associated with fast-moving systems.
For Georgia commuters, students, and outdoor workers, the primary impacts during this period will be cooler daytime temperatures, colder nights, and increased heating demand, rather than travel disruptions. Residents are encouraged to monitor updated forecasts as temperature details and wind impacts become clearer closer to the event.
