Forecast Discussion: Air quality rebounded yesterday as most of the PM values decreased into the Good range except for the Greenwood and South Phoenix monitor. Looking ahead, a high pressure will move in today and bring sunny skies over Phoenix just in time for the holidays. Temperatures will continue to warm and reach a high of 80°F by tomorrow. Winds are expected to be light with stagnant conditions in the atmosphere. Therefore, local isolated dust activity can slightly raise the PM concentrations. But, major weather related dust activity is not likely. The atmosphere will remain dry through the weekend until a trough moves in early next week. The current model runs indicate a possible precipitation event on Tuesday. However, as head closer to the weekend, we can get a more accurate outlook. Check back tomorrow for more. Until then, have a good day and enjoy Thanksgiving with your friends and families! -P.Patel
