You have a couple of days to prepare for the next blast of cold air that moves in beginning Sunday night. Today, we will have an increase in clouds with temperatures warming to 45 this afternoon. This east wind is picking up some Atlantic moisture and spreading it our way. That will give us mainly clouds. Folks in east Georgia along the GA/SC border will have some mist and drizzle at times this afternoon and tonight.
As temperatures drop to near freezing in the northeast Georgia mountains tonight, any of that lingering drizzle could glaze over and cause some slick spots. That would mainly be around Fannin, Lumpkin, Towns, Union and White counties. We will be above freezing in the metro area as lows Sunday morning go down to 35.
The big changes move in late Sunday. There will be some pockets of light rain in the afternoon. The main area of rain moves in late Sunday night. As the cold air comes in behind it, we will see a brief changeover to snow flurries overnight Sunday into Monday morning. We don't expect accumulations in Atlanta. We could have some accumulations in north and northwest Georgia of around an inch. We have to watch for black ice to develop as the cold air will push in before much of the water is able to dry up. High temperatures Monday will only be 26.
This will be some of the coldest air that we have seen in a long time. If we get down to 5 degrees Tuesday morning, it will be the coldest air in over 30 years. We do expect a low of 5 Tuesday morning with a high Tuesday of only 25. We will have an extended period with temperatures below freezing. It will be below freezing late Sunday night into Wednesday afternoon.
