Forecast Discussion:

This morning, both PM10 (dust) and PM2.5 (smoke) have been running low in Nogales. We can thank this weekend's rain for playing a role in this good air quality. Temperatures have also been cool, bottoming out in the low 50s (at least at the airport north of town).

If anything, the cooler temperatures should be a sign that we are now entering the cool season, which means we'll have to keep our eyes on evening/morning levels of PM. Colder night temperatures will be favorable for the local build-up of PM10 and PM2.5.

The good news for air quality though is that some more active weather is in store for Nogales this week. Another low pressure wave will move through the region and result in increased winds and rain chances for Nogales again. Wednesday is presently forecast to be breezy, which will help to limit PM levels. And possible rain Wednesday night and Thursday afternoon/night would help as well.

Overall, both PM10 and PM2.5 are forecast in the Good Air Quality Index (AQI) each day for now. But either pollutant will have the potential to increase on nights when weather conditions are stagnant and dry.
