As of Saturday afternoon, all forecast regions are trending towards a code Yellow finish. An approaching cold front will pass through the state early Sunday morning, providing a much needed reprieve from the high temperatures that have been present all week, and clean out the airmass of excess pollutants. This cold front will be the dominate driver for Sunday's weather. Mostly cloudy skies, and a moderate Northwesterly breeze will also accompany the frontal passage. There is the opportunity for wind gusts up to 30 mph throughout the day. Sunday's air quality is anticipated to be much improved, with all forecast regions projected to peak in code Green for ground-level ozone.
