Forecast Discussion:

High pressure will move overhead today (Friday), resulting in the lightest winds of the period for Rillito, as well as a warm-up. Saturday will be the warmest day of the period, with highs nearing 100°F. Nevertheless, the weather pattern will return to an active mode later Saturday, and remain so through at least Tuesday. Low-pressure disturbances and waves in the region will draw temperatures away from the 100°F mark, as well as support breezy afternoons. Right now, Monday is looking to be the windiest day, with winds forecast out of the west and up to 20+ mph, along with higher gusts.

In regards to PM10 (dust), despite the breeziness this past Wednesday and Thursday, PM10 (dust) remained relatively low for the most part. Because of this, any breeziness in the near future will likely have a similar outcome. But, we can't rule out elevated PM10 on Monday. Overall, PM10 will remain in the Good AQI category.

Check back on Monday morning for the next Rillito air quality forecast!
