Forecast Discussion: Warm temperatures and mostly clear skies will continue the next few days as an upper-level ridge slowly moves over the region. The high temperature yesterday was 90?F, with similar temperatures expected the next couple days. By mid-week, temperatures will begin to cool due to a trough moving into the area, which may even bring some rain to the Phoenix area. Looking at air quality, stagnant conditions associated with the ridge over the region will allow pollutant concentrations to build up. All pollutants will likely see an increase tomorrow due to poor ventilation, but ozone will be the worst, as is typical this time of year. Pollutant concentrations will improve mid-week as the trough moves through, increasing mixing in the lower atmosphere. If the area does get a fair amount of rain later this week, it would go a long way in helping to clear out the air and also stabilize soils. This would help to suppress any significant dust event in the near future. We will continue to monitor this potential rain event through the week. Check back tomorrow for the latest. Until then, have a good day! –R.Nicoll
