Forecast Discussion:

Yuma saw great rainfall yesterday! Values were between 1 and 2 inches across the county. The Yuma Airport registered 1.12 inches! There were also some breezy winds out of the north while the storm system was moving through. Temperatures reached 61 for your high with lots of cloud cover. Dust (PM10) and smoke (PM2.5) particulates ended in the Good Air Quality Index (AQI) range for your Wednesday.

Today, we should see calmer conditions as this low-pressure system pushes out of our region. There is still a chance from some morning showers, but after 10 am, clouds should begin to clear. We should see temperatures back in the mid to high 60s and light winds out of the north for your Thursday.

Wrapping up our work week, no rain but mostly cloudy conditions expected. On Friday, we should also see temperatures reach similar highs today but winds will be light and out of the south. Thanks to all the rain yesterday, PM10 and PM2.5 will continue to be low in the Good AQI category.

Looking at our weekend forecast, storm system #2 will make its appearance in the region late Saturday into Sunday. This disturbance will bring a few additional clouds but a very minimal chance of rainfall. The highest temperatures will stay in the lower 60s for your weekend and breezy west winds are to be expected. With a few stronger winds in store, PM10 and PM2.5 values shouldn't leave the Good AQI range due to the abundant rainfall we saw yesterday. Having the ground saturated leaves less chance for blowing dust to occur and any fireplace usage should have good ventilation to move out of the area rather than linger.

Storm system #3 will make its way into Arizona late Monday night. This low-pressure appears to be stronger than storm system #2. Winds will start out being from the south and shift later in the day to strong westerly winds. We should also see some more rainfall with this next storm system. Even with the possible 20-25 mph winds, particulate levels should still remain in the Good AQI category.
