Well we’ve been warning about the cold snap since Monday and here it is with Canadian High pressure parked right over the Southeastern U.S. as seen in the surface weather chart above. The air mass is also very dry with dew points in the teens, so when that air is heated in your home the relative humidity will drop and may cause dry skin and lips or even static electricity.
Temperatures will bottom out tonight-Friday morning with a hard freeze in the mid to upper-20s and remain chilly into Monday with a narrow up and down range.
Take precautions for vehicles, plants, pets and pipes.
The next weather system includes another “wedge” or CAD event this weekend, the low pressure system in-between a “Miller A and Miller B” type, closer to a B.
The best odds of any significant ice in the NE Georgia mountains, although a nuisance amount is briefly possible in the FAR North and East suburbs. But wedges are notoriously tricky to forecast and models struggle with them so check back for updates in case things change.

FORECAST FREEZING RAIN POTENTIAL SATURDAY NIGHT-SUNDAY MORNING:
Some minor ice is possible anywhere in the green (.01) but I think the best odds of a light amount is near and north of the orange line as it looks now, obviously subject to change.
