Forecast Discussion:
Over the weekend, ozone and PM10 stayed in the Good AQI range, while PM2.5 was in the low Moderates. As for the weather, we saw afternoon highs in the mid 70's with light winds and sunny skies. Looking at today, we aren't expecting much change. Calm weather conditions may once again allow PM2.5 concentrations to reach into the low Moderates.Tomorrow, a trough will begin moving into the region, which should bring some afternoon breezes. These breezes should help lower PM2.5 levels, but may also kick up a little dust during the stronger winds. Fortunately, the winds aren't expected to be strong enough to cause any major issues tomorrow. The trough will continue to influence the region through the remainder of the week. The largest impacts will be on Thursday with strong winds and rain. We are forecasting increased PM10 levels during the early afternoon with winds gusting up around 35 mph. However, we are forecasting rain in the evening, which should cause particulate levels to drop significantly. This should help keep particulates in the Good AQI range on Thursday even with the brief period of elevated dust. Then, we forecast much lower particulate levels on Friday due to the more stable soils from the rain.
