Precipitation chances for Saturday have declined to just a slight chance. After that, the next rainfall opportunity for Yuma looks to be Tuesday. However, there will be a zone of showers and thunderstorms Sunday stretching across southern California into southern Nevada that will produce breezy conditions from the west and northwest. In turn, this may lead to a period of elevated PM10 (dust) but at this time, an acute spike is not anticipated. Overall, daily average PM10 is expected to remain in the Good range. Daily average PM2.5 is expected to follow the same pattern and remain in the Good category.
Peak 8 hour average Ozone is anticipated to reach the low Moderate range as it did yesterday. A modest downtrend is anticipated over the weekend with more cloudiness on Saturday and a decrease in commercial and transportation activities. With a typical uptrend in those activities as well as winds patterns more favorable for ozone, levels are expected to return to the Moderate category.
Peak ventilation Saturday through Tuesday will vary between Very Good and Excellent.
