Friday will get off to a gray start, but it’s not going to stay that way all day.

Eventually, a cold front that has kept Atlanta socked in by fog and drizzle will make its way out, and sunshine will return this afternoon, according to Channel 2 Action News meteorologist Brian Monahan. It’s looking pretty good for those headed downtown this evening for dueling Janet Jackson and Taylor Swift concerts — at least as far as the weather forecast.

“For the outdoor plans today, go ahead with them, especially this afternoon,” Monahan said. “The sunshine comes out. Only some isolated showers in our forecast today.”

A dense fog advisory is in place for all of North Georgia until 9 a.m. After some mist and drizzle Friday morning, Monahan is calling for only a 30% of a shower or thunderstorm late in the day, and most of the rain activity will be confined to the mountains. Metro Atlanta should stay mostly dry.

The added sunshine will also help the city to warm up. After a comfortable start in the upper 50s and low 60s, temperatures are headed for a high of 77 degrees. That’s right on target for this time of year, Monahan said.

Temperatures will still be in the 70s when doors open for the two pop icons’ shows, and they should drop into the 60s by the time concertgoers head home. Swift’s concert — the first of a sold-out, three-night run in Atlanta — begins at 6:30 p.m. at Mercedes-Benz Stadium and Jackson’s concert kicks off at 7:45 p.m. at nearby State Farm Arena.

It’s going to get really, really crowded as music fans travel downtown, and all the parking spaces sold in advance of Swift’s shows are gone. MARTA is encouraging concertgoers, and those trying to avoid the Swift-mania, to use their service. The transit authority is planning to add trains to their regular schedule, install “load and go” teams at stations, and increase police presence to monitor crowds.

While Monahan said it’s not a good idea to ditch the umbrella completely, “Swifties” won’t have to worry too much about getting their concert looks wet this weekend. Rain chances are limited Saturday, and Sunday should dry out by showtime.

“Tomorrow is your best weekend day. It should be really nice all across North Georgia,” he said. “Instead of 60s where we’ve hung out the last couple of days, we’ll be up near 80 degrees on Saturday. It’s going to be a good day to start the weekend.”

Indoor plans are a better bet Sunday, which has a 60% chance of a shower. While most of the day will be on the wet side, Monahan said it will dry out around sunset.

Atlanta's projected high is 77 degrees Friday, with a 30% chance of a shower.
