Forecast Discussion:
A slow moving Pacific weather system will bring breezy and cooler conditions over the next few days as it moves through the Desert Southwest. However, rain shadowing from the higher mountains to the west is expected to preclude chances of measurable for Yuma.
Peak 8 hour average Ozone each day is expected to remain within the Good category due to a combination of the time of year, good to excellent ventilation and cloudiness at times (mainly today).
Daily average PM10 (dust) is expected to remain in the Good category. Of note, there may be some short lived periods with elevated hourly readings when breeziness is strongest. This is most likely on Thursday evening. But at this time, the winds are not anticipated to be quite strong enough or for a long enough duration to raises the daily average out of the Good category. Daily average PM2.5 (smoke and some very fine dust) will follow similar trends.,
