Forecast Discussion:
The weather system bringing scattered showers, thunderstorms, and pockets of gustier winds to southeastern Arizona has trekked into northern Mexico per morning satellite observations. Our storm chances have faded with its departure.Abundant sunshine, warming temperatures, and a lighter wind regime starting today brings ozone to the forefront. Highest daily ozone AQI is anticipated for Thursday by a combination of long-range transport from Phoenix mixing with local ozone production. Friday through Sunday, diurnal mountain-valley winds versus long-range transport are at play bringing peak ozone down a bit. Finally by early next week a widespread wind event impacts the region to flush the airshed.
