Frigid cold air is here to stay for at least the next several days even though a weekend storm that caused power outages and canceled school is behind us.

North Georgia’s daytime highs, including in metro Atlanta, are projected to hover around the freezing mark Monday. And forecasters warn of dangerously cold overnight temperatures that could produce treacherous driving conditions, including black ice, during the Tuesday morning commute.

“The cold, arctic air has really tumbled in behind this system,” Channel 2 Action News meteorologist Brian Monahan said. “I say tumbled because the wind was so strong (Monday) morning, you can really hear that cold air rushing in across North Georgia.”

A cold weather advisory, in place from 8 p.m. Monday to 9 a.m. Tuesday, warns of dangerous temperatures across the Peach State’s north and central portions. And the strong winds up to 40 mph that blew in behind the storm will make it feel as low as minus 4 degrees in the mountains and 15 degrees overnight in Middle Georgia, the National Weather Service said.

In fact, wind chills below 5 degrees are possible as far south as the I-20 line.

Still, many metro Atlanta school districts plan to reopen Tuesday, including Atlanta, Decatur, Clayton, Cobb, Douglas, Fulton, Marietta, Paulding and Rockdale systems.

“Avoid prolonged exposure if possible and have a safe heating source,” the Weather Service warns.

Without factoring in the wind, metro Atlanta’s high temps are projected to barely scrape 40 degrees Tuesday through Friday before crashing into the 20s each night.

Metro Atlanta and the North Georgia mountains were mostly spared the worst of the winter weather, which started its slow march across the region Saturday night. But the state’s northeast corner did not escape unscathed, and this week’s frigid temps pose a threat to any residents still without power.

As of noon Monday, nearly 30,000 northeast Georgia customers had no electricity, according to power companies that serve those areas. High winds could topple more trees and power lines in the hardest-hit areas, such as White County, where Helen is.

Up to a half inch of ice was recorded there, according to the Weather Service’s early ice accumulation reports. And Monday’s projected below-freezing high temps could keep ice intact, officials warned.

“One saving grace may be that we are expecting the sun to come out this afternoon, which should aid in some melting efforts,” the NWS said.

But some locations will remain frozen through Tuesday, when temps are finally expected to reach the mid to upper 30s, the agency added.

Further south into metro Atlanta, Monday’s high temps are also expected to stay at or near freezing. But ice created by the storm has had time to mostly melt because of Sunday’s higher temperatures near the city. Wind and sunshine Monday should help evaporate more of that moisture despite freezing temps returning overnight.

Overall, ice accumulations fell short of the dire early forecast amounts, which cautioned up to 4 inches in far northeast Georgia. That projection was lowered to up to an inch as the storm arrived.

The winter storm hit other parts of the country especially hard and is blamed for at least 13 deaths, The Associated Press reported Monday morning. Some were attributed to hypothermia, and a few were related to accidents.

In Massachusetts, a snowplow backed over a couple in a parking lot, killing a 51-year-old woman and leaving her husband hospitalized, the AP reported. And two teenagers died in sledding accidents in Arkansas and Texas.
