[View the ADEQ Hourly Forecast for Phoenix]
A small low pressure system over Arizona will lead to partly sunny skies today along with a slight chance of showers and thunderstorms - this afternoon and evening - mainly for eastern and northern portions of the Greater Phoenix area. Mostly clear skies are expected Saturday through Tuesday. Anticipate some breeziness at times (most noticeably Saturday and Sunday).
Peak 8 hour Ozone each day is expected to remain in the Good category aided by the time of year and favorable ventilation.
Daily average PM10 (dust) will fluctuate and be near the Moderate threshold at times but is expected to remain in the Good category aided by favorable ventilation.
Daily average PM2.5 (smoke/combustion particles) is expected to be in the low Moderate range most days (dipping to the upper Good range Sunday) due to a combination of transportation, industrial and fireplace activities but being offset to a degree by favorable ventilation during daytime.
