Forecast Discussion: The weekend ahead looks great with a fairly stable atmosphere. The upper-level high pressure system located just west of southern California will continue to hold off moisture over Mexico and bring clear, sunny skies over Phoenix. As a result temperatures could soar as high as 108°F during the day. Ozone will continue to be the primary concern this weekend as sunny skies stall concentrations in the Moderate range during the afternoon hours. PM concentrations will give us a break and remain in the middle Good range since weather activity has subsided. With no thunderstorm outflows or weather driven wind events, dust activity poses a low risk. Check back on Sunday for a look ahead at next week's weather and air quality. Until then, have a great long weekend with your friends and families! Be safe! -P.Patel
