Forecast Discussion:

Early this morning--shortly after midnight--winds shifted to out of the west with the arrival of a cold front. However, winds remained rather weak: the Yuma Marine Air Corps Station observed wind speeds primarily at 3 mph. And around 7 AM, winds were "calm." In regards to PM10 (dust), PM10 levels stayed low yesterday evening and early this morning, but have increased mid-morning today from local activity and stagnant conditions.

Weather-wise, today will be the coolest day of the forecast period, with high temperatures in the upper 60s. Highs are then forecast to gradually increase each day through Tuesday, reaching the mid-70s by then. Furthermore, light afternoon breezes out of the north are expected over the next several days. Cloud cover will also increase over the weekend and beyond.

Air quality-wise, except for any local dust-producing activities, no significant issues are expected with PM10, thanks to the uneventful weather. In all, both PM10 and ozone will remain in the Good Air Quality Index (AQI) through at least Tuesday.

Check back on Tuesday (1/21) for the next Yuma Air Quality Forecast.
