CBS3/CW57 will lose

Doug Kammerer

later this summer, as he's bound for the chief meteorologist's job at WRC, the NBC station in Washington.

Kammerer, who grew up in suburban Fairfax County, Va., will go head to head with one of his boyhood idols, Bob Ryan, who left WRC and now calls highs and lows on the ABC station's 11 p.m. news.

Kammerer, working the dawn patrol since Maria LaRosa left, came to Philly in 2003 to work at NBC10. He joined CBS3 in mid-2007, but had to sit out about six months due to a noncompete clause. CBS3 has not named a replacement. The station also recently lost morning coanchor Liz Keptner.

Kammerer, 35, has extended family in Washington and calls it a job of a lifetime, given that weathercasters in D.C. tend to stick around. "I expect to be there for 30 years," said Kammerer, who says he and wife Holly - with son Kenton, 3, and daughter Calli, 11 months - fell in love with Philadelphia. "This is really going to be tough on Holly," he said.

Take the Stairs, too

Phillies fans who cheered

Matt Stairs

for a season and a half saw less of him over the last few days when he and his new team, the San Diego Padres, were in town. That's "less of him" because Stairs, 42, lost 37 pounds during the offseason with NutriSystem. "I thought I was too light, so I put seven back on," Stairs told me. Phils manager

Charlie Manuel

, another NutriSystem client, hooked him up with the Horsham company. He totes his meals on the road and microwaves 'em. And he knows it works. He visited a local sports bar Sunday night to watch the Flyers game, and whispers went around that he was in the house. But two bar workers, he told me, demanded to see his ID to verify. "People say, 'Yeah, where's the rest of you?' "

B sharp

Kevin Eubanks

says that when he was growing up, he wanted to be a music teacher, like his mother, Vera. Eubanks, a Germantown High grad who went on to Berklee School of Music, will do that in his new life, following his departure last month from the

Tonight

show. He says he'll teach at the Thelonious Monk Institute of Jazz in L.A., among other projects, including CDs and the pilot for his own cooking show. Eubanks told me he's "completely honored" to get a plaque on the Philly Music Walk of Fame; the ceremony will be June 17 next to

Charlie Gracie's

plaque outside the Doubletree Hotel at Broad and Locust Streets. "A lot of people are not aware of how much music has come out of Philly and how much Philly music has had an impact on the music world," Eubanks said.
