Forecast Discussion:
This morning (Friday), both PM10 (dust) and PM2.5 (smoke) have been running a little bit higher at the Nogales monitor, compared to previous mornings. The main effect this will have will be PM2.5 now likely reaching the Moderate Air Quality Index (AQI) category today. Afternoon winds will be out of the southwest today, but they'll die down for the evening, favoring elevated local PM levels.The main story for this forecast period, however, is a low pressure wave that will dive into Arizona today, stall over the state all day Saturday and into Sunday, then begin to depart later Sunday. This system will result in breezy southerly winds tomorrow (Saturday). It will also bring Nogales its next rain chances, the window for rain looking to be late Saturday into Sunday. In fact, thunderstorms may even be possible on Sunday. After Sunday, weather conditions are expected to calm down again.
Air quality-wise, the upcoming winds and rain will help to limit local PM10 and PM2.5 levels. But PM2.5 will continue to be the main pollutant to watch, as it will have a greater likelihood of reaching the Moderate AQI category. Any morning/evening with cold and stagnant conditions will be favorable for elevated PM2.5.
