WEDNESDAY’S WEATHER-TRAFFIC: Cold front arrives ‘right on cue’ for first day of fall

A cold front arriving in North Georgia on Wednesday will sweep away all this wet, muggy weather and drop temperatures just in time for the changing of the seasons.

The weather system will move out of metro Atlanta “right on cue” as the autumnal equinox occurs at 3:20 p.m., according to Channel 2 Action News meteorologist Brian Monahan. Temperatures will begin crashing behind the front, Monahan said, bottoming out in the 40s and 50s by Thursday morning.

“Pretty much right on schedule, fall gets here at 3:20 p.m., a cold front is going to be here about 3:20 p.m., and temperatures are going to look a lot like fall,” he said. “More like October weather by the way, by the time we hit tomorrow morning.”

On average, Atlanta does not reach the 50s for lows until the first week of October.

Ahead and along the front, there is still a chance for rain Wednesday. Monahan said metro Atlanta should stay mainly dry until about lunchtime, when the front arrives and increases the chance of a shower or thunderstorm. He does not expect any severe weather, but there is a 60% chance of downpours.

“The good news for your morning commute: Between now and about 9 a.m., not a whole lot of rain,” he said.

Once the front blows through, Monahan said it will turn breezy and cooler. Temperatures are expected to top out at 77 degrees Wednesday, according to Channel 2.

All the rain and showers should be gone by Wednesday evening, and North Georgia is looking at a rain-free forecast all the way through the weekend. Cooler weather should stick around, too, with lows in the 50s and afternoon highs in the upper 70s, according to the latest forecast.

As far as the Wednesday morning commute, conditions are pretty near ideal at 6:45 a.m. Pavement is dry and there are no major delays inside the Perimeter, according to the WSB 24-hour Traffic Center.

It’s so far a great ride on I-75, Ga. 400 and I-85, traffic reporter Heather Catlin said. Although volume is building, there are speed limit conditions on all three freeways out of the northern suburbs, she said.
