Forecast Discussion:
Strong winds have already developed across southeastern Arizona and dust has already begun spreading into central Arizona. The dust has moved in faster than anticipated, so we have adjusted the timing of the dust. Additionally, given the concentrations we are already seeing around the state, we have increased the forecast further into the Moderate AQI range for today.
Winds will continue to be strong throughout the day and continue into tomorrow as well. We are still forecasting PM10 levels to be a little elevated tomorrow, but we don't anticipate concentrations as high as today. Then on Sunday, rain chances and lighter winds should bring particulate levels back down into the lower Good range.
