A cold front, upper low and surface low are the main weather players for the weekend forecast. Tomorrow, as the system gathers steam to our west, we'll notice our winds turning more southerly and moisture/warmth will move in. So I expect temps to rebound much more than they did today, despite still having some clouds around through Friday.
As the cold front draws closer on Saturday, our shower and storm chances will increase. Mountains will see rain first, then it will push into the Upstate and northeast GA. I don't expect the widespread, heavy rain that was once in the forecast though! An area of low pressure will develop along the Gulf Coast and stay well south of us, which will act to steal most of the available gulf moisture for our cold front to tap into. Therefore, I'm thinking 0.5" rain totals for most spots. Timeframe: late Saturday afternoon through early Sunday morning. Severe weather threat will be pretty low, but an isolated strong storm will be possible during the heat of the day Saturday.
The bigger story with this cold front will be the cooler air that moves in! Sunday night's lows will fall into the mid 40s for Upstate and upper 30s in the mountains. Then Monday night we'll get to near 40 in many Upstate spots and low to mid 30s in the higher elevations. So, we may be looking at another night where you'll want to cover or bring in your plants if you live in the mountains! The cooler air won't have a ton of staying power, we'll be back to near 80 by late week.
