— -- ABC News chief meteorologist Ginger Zee and her husband Ben Aaron welcomed their second child, a baby boy.

Zee, 37, gave birth to the healthy baby, named Miles Macklin, Friday morning in New York City.

Zee posted on Instagram that the baby weighed 8 pounds and 7 ounces, and was 21.5 inches long.

Zee and Aaron, who wed in June 2014, are already the proud parents of a 2-year-old son, Adrian.

Zee tweeted news of the birth, posting a picture of Adrian in blue hospital scrubs -- adorned with "Big Brother" on his top -- with the caption: "Scrubbed in, delivered a healthy baby boy and got a cookie to celebrate. It’s been a good day."

In August 2017, Zee announced to “GMA” viewers that she was expecting her second child with a special weather map.

Zee described Adrian as "very excited" to become a big brother, adding that she and her husband tried to prepare Adrian for his little brother with a "special big brother T-shirt that matches a little-brother onesie," tours of the baby’s new room, and books and shows that discuss the subject of becoming a big brother.

Zee and Aaron reside in New York City.
