Those headed to the polls Tuesday morning will want to dress for winter.

Temperatures are in the upper 30s in metro Atlanta, the coldest weather since early spring for many neighborhoods. A frost advisory is in effect for all of metro Atlanta until 9 a.m., according to the National Weather Service.

Channel 2 Action News meteorologist Brian Monahan said a heavy coat is necessary through 10 a.m., but temperatures will climb steadily once the the sunshine gets going.

Atlanta is expected to reach a high of 65 degrees Tuesday afternoon, according to Channel 2.

“If your plans are to vote later in the afternoon, you’re looking great,” Monahan said. “If you are going to vote after work, make sure you have a jacket. When the sun goes down, temperatures will get chilly if you are waiting in line.”

Without the warm sunshine, temperatures will fall into the mid-50s by the time polls close at 7 p.m., he said.

There will be no rain to worry about Tuesday, according to Channel 2. A chance of rain does not return to the forecast until the end of the week.

Warmer weather will also make a return.

“How long does the cool air last? Not very long,” Monahan said. “We’re going to see warmer temperatures start to move in. After this morning’s cold temperatures, we’re warming up into the 70s as we go toward the end of the week.”
