Temperatures in the region will climb into the 80s and 90s, accompanied by reduced air quality due to wildfire smoke

No alerts have been issued, but the air quality may approach “code orange” levels again late Thursday afternoon in parts of the region, as it appears that the ozone factory will still be operating while the Canadian wildfire smoke persists in the skies over Philly.
