That was quite a wild weekend for dust in the area. On Friday, dust moved in early in the morning from thunderstorms well to the south. On Saturday, another outflow out of the south in the evening caused more significant dust in the area. And lastly on Sunday, there was lingering dust through most of the day, then another outflow in the evening brought more dust. Fortunately, this morning is looking much better as it looks like we finally had enough coverage of rain to clear out the air and stabilize soils.

Looking ahead, we are forecasting today and tomorrow to be little calmer as far as thunderstorm outflows go. Therefore, with yesterday's rain and lack of strong outflows, we expect PM10 levels to end up in the Good AQI category today and tomorrow. On Wednesday, there is potential for a strong outflow to push through the area again, however, with more stable soils, we don't expect as much dust as we saw over the weekend.

As for ozone and PM2.5, they are forecast to stay in the Good AQI category through the week.
