Georgia Winter Forecast: Polar Vortex and El Niño to Shape Season
The Old Farmer's Almanac predicts a wetter-than-usual winter for Georgia, influenced by El Niño and the polar vortex. El Niño, a warming of Pacific Ocean waters, is expected to shift the jet stream, steering storms and moisture across North America. The polar vortex, a mass of frigid Arctic air, may weaken or shift, allowing colder air to spill southward, potentially bringing wintry outbreaks to Georgia. Ocean patterns such as the Atlantic Multidecadal Oscillation and Pacific Decadal Oscillation are also being monitored for their impact on storm activity and moisture distribution. The National Weather Service (NWS) corroborates these predictions, forecasting above-average precipitation for Georgia, with chances increasing further south. Temperatures are expected to remain near average for the winter months. Source time: Tue, 18 Aug 2026 19:00:00 GMT.
