"So many of you have been thoughtfully asking where I've been. Last week I was admitted to the hospital w/blood clot in my leg which sent some clots into my lungs," he said in a Friday morning Twitter post, which included a photo of flowers and an NBC News weather mug.

"I am so fortunate to be getting terrific care and on the way to recovery. Thanks for all the well wishes & prayers," the "Today" show weather anchor — who's been with NBC for over four decades — added.

His colleagues sent well wishes to the 68-year-old after his announcement.

According to the Centers for Disease Control and Prevention, hundreds of thousands of Americans suffer from blood clots, which could be fatal, every year.

They can start in various parts of the body, like the lower leg, and travel through the bloodstream to one's lungs.
