Forecast Discussion:

Currently over the Pacific Northwest is an upper-level shortwave expected to dig a fraction to the south, and then propagate eastward throughout the day. This system specifically will not impact Arizona very much, but an interesting synoptic pattern has taken shape, with most models now in agreement for chances of precipitation in the southeastern portion of the state starting this weekend and into Monday.

A strong high pressure centered over southern Mexico is causing upper air over the state of Arizona to move to the northeast. In accordance to this, another shortwave off the Pacific Ocean is expected to move over land by early Monday morning, causing flow to once again move to the northeast over Arizona. A high and a low are both aiding this synoptic flow over the state, and with a source of moisture and some vertical velocities thrown in, models are hinting at rainfall that could possibly persist over southeastern Arizona starting tomorrow and through Monday.

As for Yuma, chances for rain are minimal, and with stagnation continuing at the surface throughout the weekend it looks like Yuma may continue its air quality trend of... not much change, if any change, locally driven.

For your air quality forecast, ozone levels will fall throughout the weekend has cloud cover begins to shroud the area starting today and through the weekend. PM10 (dust) and PM2.5 (smoke) levels are expected not to change very much, and any significant changes will be locally driven. All parameters are forecasted to remain in the Good AQI throughout the period.
