Forecast Discussion:

In yesterday's forecast we did forecast a brief spike in PM10 early this morning due to the potential of outflow winds. While Thunderstorms in central Arizona yesterday evening did send outflows towards Yuma, which arrived just after midnight, the winds were not at all impressive and there was not any dust associated with it by the time it reached Yuma. As a result we have adjusted the PM10 forecast for today lower into the Good AQI range. As for the rest of the period, we aren't expecting any significant winds from thunderstorms to reach Yuma, and therefore forecast PM10 to stay in the Good range. Ozone is also forecast to stay in the Good range as mostly southerly winds out of the gulf are expected. This prevents any ozone transport from California to affect Yuma.
