If the roads look shiny Wednesday morning, watch out for patches of ice and use caution on your morning commute.

Chattooga County schools will open three hours later Wednesday, due to projected cold temperatures and moisture on the roads, officials said.

Channel 2 Action News meteorologist Brad Nitz said road temperatures were near or below freezing Tuesday afternoon in parts of north Georgia, where slippery conditions were expected to develop first Tuesday evening and overnight.

“It’ll be later this evening,” Nitz said. “And overnight, any spots that had some melting will refreeze or a few flurries could coat the roads. But that will be few and far between in the metro area.”

Chief meteorologist Glenn Burns said the north Georgia mountains would get a “maybe a little dusting,” but no more.

As snow continued to fall Tuesday in metro Atlanta, districts started cancelling after-school activities. North Georgia public health departments closed at 6 p.m., due to hazardous conditions.

The Cherokee County School District canceled after-school and evening activities. Cobb said activities after 6 p.m. were canceled "due to possible hazardous road conditions." Fulton announced activities would stop at 6 p.m., too.

In Clayton County, all outdoor activities were canceled, but all indoor activities were scheduled to continue as planned.

On social media, snow sightings across metro Atlanta were reported early and often.

A winter weather advisory issued Monday for black ice and slick roads was expanded Tuesday to include Cherokee, Bartow, Floyd and Gordon counties, and will remain in effect through 10 a.m. Wednesday.

A wind chill advisory is set to expire at 10 a.m. Thursday for parts of Calhoun, Blairsville, Gainesville and other northern areas.

“You could have temperatures that feel like 5 degrees above zero to 5 degrees below zero,” meteorologist Karen Minton said. “And that can cause hypothermia and frost bite.

“Make sure the pets are staying indoors too because it’s harmful for them as well to be out in that cold that they’re going to be with the next few days.”

Wind gusts could reach 25 mph.

Cold temperatures and cloudy skies will linger for the most part Wednesday, although temperatures will come up above freezing at times, Channel 2 meteorologists said. Wednesday’s expected high is 37 degrees, and the expected low is 23 degrees.

Highs will increase later in the week, but lows are expected to stay in the 20s.
