WAFB news anchor Donna Britt, who was diagnosed with the progressive neurodegenerative disease amyotrophic lateral sclerosis, or ALS, in July, is stepping away from the 10 p.m. news anchor desk beginning Oct. 16.

The veteran news broadcaster will continue on the 6 p.m. newscast, but Elizabeth Vowell, who anchors the weekend newscasts, will join Greg Meriwether in co-anchoring the 10 p.m. news.

Britt made the announcement on her Facebook page Friday.

"I'm moving to the day shift and after the 6 o'clock news I can go home and see my son, Louis," said Britt. "I've always worked nights and that meant I'm not home until 11 or 11:30."

She said she had adopted a flexible work schedule after the birth of daughter Annie, allowing her to go home between the 6 p.m. and 10 p.m. newscasts. But, now that she relies on husband Mark Ballard to drive her to and from work, that arrangement is proving a logistical impossibility.

"So, I only get to see my son in the morning, and he's only home one more year before he's off to college and adult world," said Britt. "Now, I'll have a reasonable schedule … it's going to be sweet, exactly what our family needs. I'm going to have a much more sane life and my family will, too."

She also gave a hearty endorsement to Vowell.

"You're going to love having Liz as the queen of 10!"
