Forecast Discussion:

Over the past 48 hours, the Nogales International Airport saw around 1.15" of rainfall. Nogales itself likely saw a little less, but regardless, it was a rainy weekend.

Air quality-wise, rain is the best thing, since it effectively knocks PM10 (dust) and PM2.5 (smoke) out of the air. Therefore, it comes as no surprise that both pollutants ended up in the Good Air Quality Index (AQI) category yesterday.

This morning, plenty of moisture still abounds near the ground as soils are soaked from the weekend's rain. This moisture, in turn, is helping to keep morning temperatures relatively warmer. Both PM10 and PM2.5 have also been running low so far (as of 8 AM).

Looking ahead, the weather pattern over the U.S. Southwest will remain somewhat active, with various low pressure waves passing through. Unlike this weekend, rain is not expected. Instead, Nogales will have some breezy afternoons--particularly tomorrow. Moreover, morning temperatures are forecast to cool down, dipping into the 30s again by Thursday morning.

Air quality-wise, PM10 and PM2.5 are expected to be the lowest of the week today. But as the week progresses, both pollutants are forecast to increase each day. Given the recent rain, PM10 is currently forecast in the Good AQI category each day. However, PM2.5 is expected to rebound quicker, with Moderate levels possible later in the week.
