ATLANTA - After over two full weeks of unseasonably mild temperatures in the 60s to 70, unseasonably cold air is on the way that will come from the combined impacts of two cold fronts this week.
The first cold front will affect north Georgia starting late today with rain and possible thunderstorms (not expected to be severe). Before the front arrives, skies will be cloudy with a few sprinkles or "nuisance" rain showers and temperatures will once again rise into the upper 60s and low 70s today - running about 5-10 degrees warmer than average for early December. The biggest push of steady rain happens from late afternoon and through the evening.
Behind this front, high temperatures will run 20 degrees colder for Wednesday under mostly cloudy skies. Showers may return to some areas south/southeast of the metro area during the day, but farther north, rain is not expected.
The second front arrives Friday. Computer forecast models bring little to no moisture with this, but it will reinforce the cold air and provide an arctic blast. Weekend temperatures will be lows in the 20s and highs in the 40s for the metro area. Some parts of north Georgia may experience highs only in the 30s Saturday! We'll keep an eye on this second system, because even though moisture is limited, some models introduce the possibility of some flurries for parts of north Georgia (mainly the mountains) going from Friday night into early Saturday.
It is important to remember during the winter season to always use the LATEST forecast for your planning. Details will be changing over the next few days on whether flurries will fly, or if all of north Georgia stays dry. At this point, even the worst case scenario would not have a high impact.
