The Buffalo Bills (9-2) and San Francisco 49ers (5-6) are scheduled to kickoff at 8:20 p.m. ET on "Sunday Night Football."
Crews have been working since Saturday to clear Highmark Stadium after a major lake-effect snowstorm battered the Buffalo metro region this weekend.
Just a couple hours before kickoff, retired winter weather expert Tom Niziol, formerly of The Weather Channel and National Weather Service, posted an update as the wintery weather continued to show signs on life despite the heaviest snowfall having already wrapped up.
"I was afraid of this. This is a very intense lake-effect snow band off Lake Huron, and is stretching down toward WNY and Orchard Park," Niziol wrote on X with an accompanying video showing multiple lightning strikes. "It has lightning in it as you can see as well. I will monitor it, but it could put a real wrench into the @BuffaloBills game. @NFL."
When asked by a commenter about a timeline for the snow band to potentially arrive in southern Erie County, where Highmark Stadium is located, Niziol responded, "Hard to say and my hope is it slides south of the stadium IF it even holds together."
