Forecast Discussion: Ozone is the main topics of concern for this forecast period. Friday, the Saguaro Monument monitor came in with an AQI of 71 and yesterday it topped out at 74.

The weak disturbance that moved through the area yesterday bringing some clouds to the city is moving eastward into Mexico today. High pressure will anchor itself over the western US this week which will mean warm temperatures and light winds. These conditions will be prime for ozone production within the Tucson area. Forecasting ozone to end the today in the mid/upper Moderates and tomorrow we are expecting it to near the Federal Health Standard. As a result, an Ozone Health Watch will be issued for Tucson on Monday.

Another very weak disturbance will move through Arizona on Tuesday which will increase clouds so we will be watching ozone trends closely. Right now another Ozone Health Watch is possible on Tuesday.

The pattern does not change much through the week, so an Ozone Health Watch will be possible through at least Thursday. We will update the forecast tomorrow morning with more information on these potential health statements.

As for PM-10, not expecting any issues within the Tucson area; however, Rillito will likely see some spikes throughout the week due to local dust producing activity.
