Forecast Discussion:

Not much has changed from the weather story this week in Yuma. Yesterday (Thursday) was another calm and quiet day with light winds out of the north and temperatures just scrapping the 90-degree mark. High pressure continues to build over the southwest region, resulting in more calm conditions to wrap up the workweek.

Over the weekend and into next week, weather conditions will begin to slightly change. A low-pressure system is going to move in over the Pacific Northwest which will weaken the ridge that's currently over Arizona. As a result, winds will shift out of the west, and temperatures will drop into the mid-80s. On Monday, another disturbance is looking to move in from the Pacific Northwest, but this one will dip further south. From this next trough, we'll see breezy winds at the beginning of next week. Monday evening through Tuesday morning, sustained wind speeds are forecast to be between 10-20 mph, with higher gusts possible.

As for air quality, stagnate conditions and local activity are continuing to cause elevated PM10 (dust) and PM2.5 (smoke) levels. Yesterday, PM10 did reach the Moderate Air Quality Index (AQI) category from these conditions. Going forward we have a few more days of Moderate PM10 levels expected. Today, higher values will be a result of stagnate conditions and early next week, Moderate values will be due to strong winds. Otherwise, particulates are forecast to remain in the Good AQI category this period. There are no concerns with ozone at this time.

Have a great weekend!
