Forecast Discussion:

Another day, another dry system comes and goes in the desert southwest. Building high pressure will be the main story for this week, but after a nearby disturbance forcing northerly winds throughout the state of Arizona over the next couple of days. Northerly breezes from today to Thursday will incapsulate the state, bringing possible blowing dust to certain areas.

Air quality in Nogales yesterday came in as expected, with the usual morning and evening signatures in PM10 (dust) and PM2.5 (smoke). The steady increase in particulates will continue today, but in this case, northerly breezes may help to keep airborne particulates down, and disperse them out of the area. During the early morning and late evening hours, when winds taper off to more terrain driven flow, PM2.5 has been much higher than during the day with this morning to be no exception.

Even though daytime winds will help with air quality, the morning and evening values of PM2.5 will carry the daily value into the Moderate AQI for today and through most of the week. PM10 will continue to increase as the surface dries out more and more. Levels are expected to reach near Moderates by the end of the week.
