Forecast Discussion:
Expect only minor breeziness this afternoon and again Tuesday bur otherwise light winds will prevail. Though a follow-on upper low pressure system will slowly pass overhead the next few days, there will be too little moisture for it to work with to yield any precipitation. Temperatures will be below normal for a couple of days before warming to near normal early next week.
Peak 8 hour Ozone values are expected to remain in the Good category through Tuesday due to the time of year (declining daylight hours) and wind patterns.
Daily average PM10 (dust) values are expected to remain in the Good category as winds are not expected to be strong enough to generate blowing dust. Of note, there will be some short lived periods in the mornings with somewhat elevated hourly values (mainly Monday and Tuesday) but not enough to raise the 24 hour average out of the Good category. Daily average PM2.5 (smoke and some fine dust) will follow similar patterns.
