Forecast Discussion:
This weekend will be characterized by a cooler pattern, thanks to a low-pressure wave/circulation over the region. Then by Monday, higher pressure will move into the region and cause temperatures to warm up again. As for winds, we'll remain mild compared to the past couple days, with some light afternoon breezes possible today and Saturday. Rain chances will be absent through the period.
In general, PM10 (dust) and PM2.5 (smoke) will be highest in the mornings/evenings when conditions are coolest and most stagnant. But PM2.5 should be able to rebound a bit quicker than PM10 after this week's rain.
For now, PM2.5 has the greatest potential at reaching the Moderate AQI category.
Check back again on Monday for the next Nogales Air Quality Forecast.
