Forecast Discussion:
This evening, Pinal County could see its first strong thunderstorm outflow winds of the summer. These winds would/will originate from thunderstorms to the east. Blowing dust will be possible, even significant dust could be possible. We've thus increased the hourly PM10 (dust) graph to reflect this potential. Uncertainty makes it hard to pin down how high PM10 levels could reach. This will be the first test of the season, to see how much dust might be out there.
After today, there will be more opportunities for wind-driven dust this week: tomorrow evening and during the afternoons over the weekend. Moderate levels of PM10 will be possible.
PM2.5 will generally follow PM10 trends.
Lastly ozone levels will likely continue in the Moderate AQI category the next few days. But over the weekend, stronger winds should help to limit ozone levels and perhaps push them back down into the Good AQI category.
Check back tomorrow for the next update to the West Pinal forecast.
