Forecast Discussion:

The forecast remains relatively unchanged from yesterday. High pressure is currently centered over Idaho, a weak disturbance is located off the coast of California, and the disturbance we have been watching all week is now just southeast of Arizona as it slowly moves westward.

The disturbance will continue to slowly move westward and stall out just south of Arizona tomorrow as the high moves eastward in response to the weak disturbance off the coast of California lifting northeast, with the tail end moving through Arizona. With plenty of moisture in place combined with lift from both disturbances, expect storm chances to increase tomorrow into the weekend. As is typically the case for Yuma, not expecting high rain chances, but they will be in the 20-40% range, which is better than nothing! Also, given the high moisture content, any storms that do move into the region will be capable of producing heavy rain.

By Sunday into the first part of next week, high pressure is expected to build eastward into the southwestern United States, which will turn the flow more out of the northeast, limiting storm chances.

As for air quality, ozone is forecast to be in the Good AQI category through the forecast period. PM-10 (dust) is running much lower than forecast yesterday, so we will lower the 24-hour average back into the Good AQI category. With that said, we are expecting another chance of blowing dust late tonight into early tomorrow morning as outflow winds move through the region.
