Dave Schwartz, a longtime Weather Channel meteorologist who early this year told his viewers about his struggle with cancer, died of the disease on Saturday. He was 63.

The Weather Channel, based in Atlanta, announced his death on its website but did not say where he died. Mr. Schwartz learned he had stage 2 pancreatic cancer 10 years ago, the station said, but twice overcame it before it resurfaced last year.

Often referring to viewers as “my friends” before giving forecasts, Mr. Schwartz presented an easygoing manner and a gentle sense of humor that made him popular with viewers, the station said.

He was born on Feb. 20, 1953, in Philadelphia, where he grew up and earned a degree in psychology from Temple University. He received a certificate in meteorology studies from Mississippi State University.
