Before you walk out the door Tuesday morning, grab everything you can think of to stay warm, metro Atlanta.

“We’ll be in the upper 20s with a few passing flurries or snow showers,” Channel 2 Action News chief meteorologist Glenn Burns said.

Don’t panic. No need to run to the store and wipe clean the bread and milk aisles. And no need to fret over how you’ll make it to and from work and school.

“Gusty northwest winds and very dry surface air will make potential for any black ice very remote,” Burns said. “I expect flurries or snow showers to continue through the day with little to no accumulations.”

Heavier snow accumulations are expected in the north Georgia mountains, which could get at least 1 inch and up to 2 inches of the white stuff.

“Maybe even greater amounts,” Burns said.

A winter weather advisory previously set to expire at 7 p.m. Tuesday was extended Monday afternoon until 10 a.m. Wednesday for Dawson, Fannin, Gilmer, Lumpkin, Murray, Towns, Union, White, Catoosa, Whitfield and Rabun counties, where there is potential for black ice Wednesday morning.

The office of state Insurance and Fire Commissioner Ralph Hudgens urged Georgians to drive with caution.

“Inclement weather does not absolve you of liability should you have an automobile accident,” said Glenn Allen, a spokesman for Hudgens’ office. “It is your responsibility to drive with a degree of caution warranted by hazardous conditions.”

Eight the counties covered by the winter weather advisory — Dawson, Fannin, Gilmer, Lumpkin, Murray, Towns, Union and White — were also under a wind chill advisory until 10 a.m. Wednesday. That means very cold air and strong winds could combine to generate low wind chills that can lead to frost bite and hypothermia if precautions are not taken. Pickens County was included in that advisory, too.

Is there any relief in sight?

While Wednesday will bring clearing skies, the cold is here to stay. Atlanta will wake up to a low of 22 degrees on Wednesday and 20 degrees on Thursday.

“That would mean mid-teens in the suburbs,” Burns said.

The high in Atlanta will be 37 on Wednesday and 41 on Thursday.
