January in the Central Savannah River Area has been warmer than what many residents expect from midwinter, and as the month reaches its midpoint, the pattern is becoming clearer: winter is still present, but it is behaving differently. Several afternoons have already climbed well above seasonal norms, giving parts of the region a spring-like feel during what is traditionally the coldest stretch of the year.
According to the National Oceanic and Atmospheric Administration, long-range outlooks for the Southeast indicate a winter pattern favoring above-average temperatures. NOAA climate forecasts show much of Georgia trending warmer overall, even as periodic cold fronts continue to move through. The agency’s Climate Prediction Center reports that large-scale atmospheric patterns this season are limiting how often prolonged Arctic air settles over the southern United States.
The National Weather Service notes that the jet stream has played a central role in shaping these conditions. Rather than dipping south and stalling, it has remained more progressive, allowing cold air to pass through quickly instead of lingering. For the CSRA, this has resulted in warmer daytime highs paired with cool nights, rather than extended stretches of deep cold.
Historically, January daytime temperatures in the CSRA average in the mid-50s, with nighttime lows typically falling into the mid-30s. Over a full January, highs are usually confined to the upper 50s or low 60s, while the coldest nights can dip into the low 30s and occasionally below freezing. This year, however, several early-January afternoons have already reached the upper 60s and low 70s, placing them well above long-term averages.
Despite the warm start, freezes have not been ruled out. Weather agencies continue to stress that January remains part of the region’s core winter season. Clear nights following passing cold fronts can still produce freezing temperatures, particularly in rural and low-lying areas. The difference this year appears to be duration, with freezing events more likely to be brief rather than prolonged…
