Forecast Discussion:
Drier air has overspread much of Arizona and thunderstorm activity today will be only isolated at best and be limited to areas near the New Mexico border. No storm activity is anticipated across the state Saturday through Tuesday. Near normal high temperatures are expected through Monday before a significant warming trend begins Tuesday.
Peak 8 hour average Ozone levels are expected to be in the upper Good range today and gradually increasing to the Moderate range Monday and Tuesday as high pressure strengthens over the region.
Daily average PM10 values are expected to remain in the Moderate range due to some lofted dust associated with agricultural activities accumulating during the portions of the day when the temperature inversion is present (mornings and evenings).
Daily average PM2.5 values are expected to remain in the Good range with transportation and industrial activity not expected to outpace the warm season ventilation.
