Though fall is officially on the calendar, it may not feel like it Sunday in metro Atlanta.

Temperatures will be above average, with some showers possible in the afternoon, Channel 2 Action News meteorologist Brian Monahan said.

“It’s very, very hot for this time of year,” Monahan said.

Sunday’s expected high of 87 is 7 degrees above average. By noon, the temp already should be at 81.

There’s only a 10 percent chance of rain Sunday, but it increases to 60 percent when a cold front moves in Monday.

But that front won’t last long, meaning the above-average heat will be back in full swing by midweek, Monahan said.

The Atlanta Falcons’ rivalry game against the New Orleans Saints at 1 p.m. will be inside Mercedes-Benz Stadium. However, downtown traffic before and after the game will likely be affected.

The National League East champion Braves also play the Philadelphia Phillies at 1:35 p.m. at SunTrust Park, which should also be warm, mostly dry and will likely feature less champagne-popping than Saturday’s game.

It’s important to remember that this weekend is the first time those with Peach Passes have to pay the tolls for the new Northwest Corridor Express Lanes in Cobb County.
