Forecast Discussion:

This morning, water vapor shows strong high pressure continuing to dominate the weather pattern across the Southwestern United States. For the most part, high pressure will be the name of the game through Sunday, with the exception of a very weak disturbance that will quickly brush through the state tomorrow (Saturday). This pattern will keep the well above average high temperatures in play and light winds, with the exception of some increased north breezes tomorrow as the system sweeps through.

Changes begin to take shape as we head into the first part of next week. An area of low pressure is forecast to drop southward through Arizona and into the northern portion of Mexico Monday into Tuesday. It will continue to spin along the coast of Northern Baja Wednesday. While this system will initially have very little moisture with it, as it spins over Baja, it will likely be able to pull up some subtropical moisture and usher it into Arizona starting Tuesday. As a result, rain chances are forecast to increase Tuesday into Wednesday. There is still plenty of uncertainty in just how much moisture this system will draw up into the state; however, right now, it looks like rain totals could be in the 0.25-0.75 inch range.

This system will also help drop afternoon high temperatures back into the low 60s to upper 50s Tuesday into the end of next week.

As for quality, forecasting both PM-10 and PM-2.5 to be in the Moderate AQI category through Monday before dropping into the Good category Tuesday with the more active weather.

Have a great weekend!
