Atlanta United’s rowdy, proud fandom will descend on downtown Atlanta Monday morning to celebrate the team’s big MLS Cup win — and weather shouldn’t be nearly as miserable as it was Saturday night.

According to Channel 2 Action News meteorologist Karen Minton, weather during the parade and pep rally, which kicks off at 10 a.m., is forecast to be chilly and wet. But at least the precipitation won’t be heavy, she said, and it definitely won’t be freezing.

Patchy, light rain and drizzle are expected throughout the day on Monday, Minton said. The temperature at 10 a.m. is forecast to be about 40 degrees. Metro Atlanta should not warm up much beyond that, with highs projected in the low 40s Monday afternoon, according to Channel 2.

“It’s going to be chilly with a chance for some rain showers this morning through the parade and rally — but I know that’s not going to keep United supporters away,” Channel 2 meteorologist Brian Monahan said.

Even if there are some showers, it's no secret that Atlanta United fans know how to party in the rain.

The parade will begin at the corner of Peachtree and Baker streets and culminate with a noon pep rally in The Home Depot Backyard near Mercedes-Benz Stadium.

The open-top bus parade will travel down Baker Street, Marietta Street and Andrew Young International Boulevard. Those streets are closed until the parade passes, according to Atlanta police. All streets are expected to be reopened by noon.

Several MARTA bus routes will also be changed because of the parade, according to the transit agency. The affected routes are 26, 40 and 816.
