ATLANTA (AP) — Forecasters say they expect some of the coldest temperatures of the winter season across north Georgia when arctic air moves into the region, dropping temperatures to near 15 degrees in some parts of the mountains.

The National Weather Service says the bitterly cold temperatures are expected Sunday across all of north Georgia, and that some winter precipitation will be possible Monday into Monday night.

Forecasters said in Thursday morning advisories that it was still too early to predict how much precipitation might fall.

The weather service is calling for low temperatures early Sunday morning of about 15 degrees in Blairsville; 18 in Dalton; 21 in Gainesville; and 22 in Atlanta.
