EAST RUTHERFORD, New Jersey (AP):Smoke from the Canadian wildfires that has engulfed the Northeast in haze is expected to mostly clear from the New Jersey area just in time for the World Cup final today, thanks to thunderstorms passing through the area, meteorologists say.Warnings of unhealthy air quality remained in effect yesterday across a wide swath of the United States. At MetLife Stadium, where the final is taking place, it rained heavily and thunder boomed. State police urged people to leave the stadium seating bowl and field and take shelter. Volunteers and staff dashed inside for cover as ponchos were handed out. The sky was the same thick, soupy grey it has been for days.New Jersey Governor Mikie Sherrill warned residents yesterday about the potential for damaging winds, tornadoes, flash flooding and large hail. Spain’s training session ahead of the final against Argentina was suspended at a nearby field because of the storms and lightning in the area. And FIFA said it was in close contact with local authorities as it continues to monitor the impacts from the wildfire smoke and the storms on the conditions on field at MetLife Stadium.STORMS WILL HELP CLEAR THE AIRThis storm front will largely move the smoke out of the Northeast before the final between Spain and Argentina, said Tyler Roys, a senior meteorologist at AccuWeather. MetLife Stadium, which has been renamed the New York/New Jersey Stadium for the matches, is an open-air stadium.“There could be some lingering smoke that would make things hazy, but very faint,” Roys said. “In terms of the thickest smoke, the smoke that has really been eye-popping and leads to poor air quality, that is not expected across New York City or much of the Northeast.”Meteorologist says the air quality for the game ‘won’t be dangerous’WFLA-TV chief meteorologist and climate specialist Jeff Berardelli, in Tampa, Florida, echoed that, saying the storm front would “sweep the atmosphere clean,” leaving only a thin smoke that World Cup spectators may still smell in the air.The air quality index shows an improvement from unhealthy air for sensitive groups yesterrday to “moderate” air quality yesterday in East Rutherford, which means little to no health risk for the general public.“It won’t be dangerous anymore,” Berardelli said. “It’s going to be dramatically better.”Temperatures are forecast to be around 80 degrees Fahrenheit (27 degrees Celsius), with light breezes and low humidity for the start of the final.“You couldn’t have asked for much better weather for the World Cup,” Berardelli added.Both Roys and Berardelli expect the heavier smoke today to be concentrated closer to the fires, hanging over parts of the Midwest and the Great Lakes region.Wildfires have been igniting across Canada and northern Minnesota this month. Berardelli said they are burning longer and faster because of climate change. The Canadian Wildland Fire Information System showed hundreds of active fires yesterday.
