Forecast Discussion: Is it summer yet? Almost feels like it out there! Nogales has been flirting with 90°F the past few days under a strong ridge of high-pressure. The heat has allowed deep mixing heights and breezy afternoon winds. Particulate concentrations have been their lowest when the winds have picked up. The problem is calmer conditions occurring overnight. Both coarse and fine particulates have spiked over the weekend during these times, likely from local activity versus any kind of import. For today and tomorrow, similar temperatures are expected with an increase in afternoon cloud cover due to a weak disturbance tracking through northern Mexico. Modest instability and mid-level moisture could create very isolated virga activity this afternoon and again tomorrow for extreme southern Arizona. By Wednesday, the ridge flattens and a transition to troughing over the western U.S. occurs. The increased surface pressure gradient means stronger southwesterly winds in the daytime (gusting over 20 mph at times). High temps also should cool a few degrees. Through midweek, upper-Good PM AQI values are likely. Check back tomorrow for the latest. Until then, have a good day! -J.Malloy
