The National Weather Service (NWS) in Peachtree City has issued a Winter Storm Watch for north and central Georgia as a significant winter weather event is expected to unfold over the coming days. High pressure currently dominating the central part of the state will shift eastward today, while a low pressure system developing in the western Gulf of Mexico is set to move northeast, impacting local weather patterns starting Friday morning.

As the low pressure system approaches, a cold wedge is anticipated to build over the eastern region of Georgia, resulting in temperatures remaining 5 to 15 degrees below the seasonal norm. While the majority of the day will experience dry conditions, increasing cloud cover is expected throughout the afternoon. Forecast models have been trending toward an increase in freezing rain, with less emphasis on snowfall, indicating a potentially messy precipitation forecast. The warm air layer aloft, situated around 700mb to 750mb, is expected to influence the weather earlier and more intensely than previously anticipated, leading to mixed precipitation types across the state. Temperatures within the cold wedge are predicted to hover around or below freezing, causing uncertainty regarding how much the wedge will erode from the south. However, forecasts suggest that the freezing temperatures will hold firm, particularly north of the Interstate 20 corridor, including the Atlanta metropolitan area.

Precipitation is expected to begin after 2 AM Friday, initially manifesting as light snow before transitioning to a mixture of snow, sleet, and freezing rain as temperatures remain below freezing throughout the day. The potential for significant ice accumulation raises concerns for hazardous road conditions and possible power outages due to ice buildup on power lines and trees. As the storm progresses into late Friday evening, most frozen precipitation will likely change to rain in areas south of I-20, while northern regions could see ice accumulations reaching 0.2 inches or more. The icy conditions are expected to persist into Saturday, with temperatures remaining low and nighttime lows dipping into the teens, potentially leading to refreezing of any melted precipitation.

Residents in Northwest Georgia are urged to prepare for the winter weather, monitor updates from the National Weather Service, and take necessary precautions to ensure safety on the roads. Stay tuned for further updates as the situation progresses.
