Forecast Discussion:

Again, we will turn to the trusty water vapor satellite to get a snapshot of what is happening with the weather pattern this morning. High pressure is centered just east of Arizona, with a developing area of low pressure off the coast of California. Today, this pattern will result in light winds of 5-10mph, with afternoon high temperatures in the mid to upper 70s.

Tomorrow, the area of low pressure will begin moving eastward toward the coast of Southern California before moving through Arizona late tomorrow into early Thursday. As the storm system approaches tomorrow, expect southerly winds of 20-30mph by late morning Wednesday into the early afternoon hours, with higher gusts undoubtedly possible. Later in the afternoon, winds will continue but shift more out of the southwest as the system moves through the region. These winds will be strong enough to produce areas of blowing dust so use caution if traveling.

As for PM-10 (dust) concentrations Wednesday, we are forecasting a rise in values during the late morning into the afternoon hours. Right now, we are not forecasting the 24-hour average to exceed the federal health standard, so a PM-10 High Pollution Advisory will not be issued. With that said, we will be watching trends very closely.

As the system slides east of the state Thursday, high pressure will quickly build back into the area resulting in mainly clear skies, lighter winds, and afternoon high temperatures rising back into the 80s by Friday. A weak storm system will brush by the state on Saturday, resulting in another increase in breezes, but they are not forecast to be anywhere near as strong as what we may see tomorrow.

As for ozone and PM-2.5, we are forecasting both pollutants to be in the Good AQI category through the forecast period.

Have a great Tuesday!
