Forecast Discussion: A trough of low pressure extends across the West this morning. This wave will slowly inch its way eastward today into Tuesday. Later Tuesday, a ridge of high pressure will begin to build over the southern two-thirds of California and western Arizona. On Wednesday, this high pressure will continue to expand over the Southwest and be directly over Arizona by Thursday. On Friday, the high pressure is projected to weaken.

Air quality-wise this week, ozone levels are expected to track alongside the weather pattern trends. Ozone levels will be lowest today, with the greatest influence of the trough, and then increase in the following days as the high pressure strengthens. Ozone levels are forecast to be their highest on Wednesday and Thursday. We'll monitor ozone trends to see if the ozone forecasts need to be increased or not.

No issues are expected with PM-10 (dust) in the Tucson area, save for the potential of elevated levels near the Rillito monitor.

Check back tomorrow for the next Tucson air quality forecast.–M. Graves
