Forecast Discussion:

A wave of low pressure from the Pacific Ocean has migrated over the West Coast and pushed the monsoonal high pressure off to the east of Arizona. This wave will result in a more southwesterly or south-southwesterly flow over the Yuma area each day this week. Furthermore, the resultant flow will reinforce southerly winds near the ground in Yuma. This general weather pattern is expected to hold through the week.

Air quality-wise, since southerly winds typically lead to lower ozone levels in Yuma, ozone is forecast in the Good Air Quality Index (AQI) category each day this week.

In regards to PM10 (dust), yesterday evening, a brief pulse of dust moved into Yuma from the west. PM10 levels jumped up for one hour and then quickly fell back down. A similar situation may happen again this evening, as models are showing stronger winds pushing into the area from the west. However, PM10 is still forecast to remain in the Good AQI category. Otherwise, no concerns are currently anticipated for PM10, save for elevated levels from local activity.
