Quote:“Alias” star Jennifer Garner bailed on a Friday trip to Alabama with first lady Jill Biden and apparently blamed the potential for thunderstorms.

The first lady pressed forward with her plan to visit Birmingham to promote the recent expansion of child tax credits, which advocates say will reduce childhood poverty.

“Due to severe weather forecasts, actor and philanthropist Jennifer Garner will not travel for the event,” the White House said in a statement Thursday.

According to the National Weather Service, Birmingham will be partly sunny Friday with a high temperature around 81 degrees and a “40 percent chance of showers and thunderstorms after 10 am.”

The government forecast worsens Friday night into early Saturday — well after Jill Biden’s delegation is expected to return to Washington.

The overnight forecast projects: “Showers and thunderstorms, mainly after 1 am. Some of the storms could be severe. Low around 62. South wind 5 to 10 mph, with gusts as high as 25 mph. Chance of precipitation is 100%. New rainfall amounts between 1 and 2 inches possible.”

Jill Biden is scheduled to visit the James Rushton Early Learning Center in Birmingham and to deliver a speech at the YWCA of Central Alabama in Birmingham.

The trip will “amplify how the American Rescue Plan addresses childhood poverty and will cut child poverty by half,” her office said.

Reps for the “13 Going on 30” star did not immediately respond to The Post’s request for comment.

The first lady’s trip is part of the Biden administration’s “Help is Here” tour, which promotes his more than $2 trillion COVID-19 stimulus plan, which Biden signed last month after it passed Congress with no Republican votes.

The event had originally been scheduled for March 26 but was rescheduled because it was set to happen a day after a destructive tornado hit Alabama, killing five and damaging hundreds of homes.
