Forecast Discussion:

Thursday was another scorcher at 110 degrees! Heat was certainly there, but air quality was superb. Particulates were in the Good AQI range and so was ozone. Ozone was over forecasted to be in the Moderate AQI category. Southerly winds from Mexico started early in the morning and held together throughout the afternoon. Without a light westerly push or early day mix down of aged ozone aloft, the 8-hour maximum average stayed well down into the Good AQI range.

The weather pattern is a dynamic one as we zero in on the weekend. Strong winds aloft are already present in the vertical atmospheric column in response to a low pressure circulation moving inland California and the Baja. Windy conditions at surface are expected today! Speeds in excess of 25 mph should yield pockets of blowing dust between Imperial County, in the Yuma vicinity, and over the northern gulf region.

There are no adjustments to forecasted PM10 in the Moderate AQI range for today. Widespread measureable rainfall did accumulate (0.10 to >0.50 inches) south and west of Yuma on Wednesday morning. That is a wildcard in the forecast that could significantly help prevent broader areas of blowing dust.

Breezy winds and cooler temperatures extend into Saturday. Winds do back off on Sunday, but by Monday gusty downriver winds (15-25 mph) become the dominant topic. Only minor impacts to the PM10 forecast are noted with that setup, though. Tranquil weather returns after that.

Have a great weekend and enjoy those sub-100 temperature June afternoons while we can!
