Forecast Discussion: Ozone and PM2.5 are good. A deep closed low north of the Great Lakes will spin in place for the next few days so the very cool weather will continue. Weak waves will rotate around this low so that isolated afternoon thunderstorms will pop up given the cold air aloft. Temperatures will be near 10 degrees below normal on winds from the northwest.
