Foggy conditions likely in the Upstate tonight, while a northwest breeze will take over in the mountains and bring some light snow showers near the TN border! Wednesday will stay mostly cloudy in the mountains with highs near 50, while the Upstate will likely reach 60 under sunshine. There will be breezy winds area-wide through Wednesday as a cold front passes to our south.
Thursday and Friday will bring a northwest snow event for the mountains (a prolonged one!). Snow won't be all that heavy, but several inches will accumulate near the TN border through late week. During the time we'll stay clear in the Upstate. By Friday another front moves through and that will help set the stage for potential Upstate snow on Saturday.
On Saturday, the cold air in place will deepen as a trough digs farther south. Upper level energy will swing through during the day, and that will translate to light snow and rain showers on Saturday. Our computer models remain fairly consistent on these features, but the GFS model is the most excited about the snow prospect as of now. Regardless, Saturday and Sunday look cold. Moisture and the strength of the upper level energy is going to be in question. Right now I'd say we could get a dusting to inch of snow in some Upstate areas if the GFS model holds, but my overall forecast is for scattered snow showers and minimal accumulations. There will be more in the mountains. Timing for some snow to fall will be late Friday through Saturday, with the best chance for snow coming late day Saturday.
Bottom Line on Upstate/NE Georgia snow chances for Saturday:
- Late Friday night through Saturday night timing. Best chance would be late day Saturday.
- Cold air should be in place, but the upper level energy will be in question.
- Either way, this doesn't look like a big deal. Light accumulations possibly by Saturday night in the Upstate and northeast GA.
- Stay posted on the forecast...since a lot could change! If a surface low can develop closer to us, that could mean a bigger snow. OR, we could end up with a cold and dry day! Oh, the joys of winter weather forecasting!
