Wildfire Smoke Forces Game and Broadway Cancellations in Northeast.

The New York Yankees and Philadelphia Phillies postponed their home games Wednesday night due to poor air quality caused by a dense plume of smoke from Canadian wildfires that has enveloped the northeast. Emmy Award-winning actress Jodie Comer abruptly walked offstage during an afternoon matinee of the Broadway one-woman play Prima Facie, saying the poor air quality made it hard to breathe. The smoky air is expected to continue through Thursday, affecting cities from Boston to Atlanta.
