Forecast Discussion:

Yuma's weather conditions will steadily hold mild today through Monday. Winds will remain light, skies will be mostly sunny, and high temperatures will increase each day, approaching 80°F by Monday. Then on Tuesday morning, a low pressure disturbance will pass just to the north of Arizona. This wave will be close enough to cause a pressure gradient to develop over the Colorado River Valley. As a result, breezy winds out of the north are forecast throughout the morning on Tuesday. Highs will dip into the mid-70s again as well.

In regards to air quality, the main focus is Tuesday morning's winds. Right now, it's hard to say how PM10 (dust) will respond, considering the recent rain from Feb. 10-11. And there's still inherent uncertainty in the timing and strength of the winds. Hourly forecast PM10 levels have been increased on Tuesday to account for the possibility of dust. But PM10 is still forecast in the Good Air Quality Index (AQI) category.

Both ozone and PM10 and are forecast in the Good AQI category each through at least Tuesday. Check back Tuesday morning for the next Yuma Air Quality Forecast.
