Forecast Discussion: Updated Wednesday, June 28, 2017 Afternoon breeziness and some moderation in afternoon high temperatures (i.e. several degrees lower) over the next day or so. Some blowing dust is expected during the afternoon hours as the wind gusts approach 30 mph. The forecasted PM10 levels are in the upper good to upper moderate range on the AQI scale, just below the PM10 Health Watch criteria. Less in the way of winds on Thursday and especially Friday will result is slightly lower PM10 levels, excluding Hidden Valley which is expected to see a slight bump in PM10 concentrations due to local dust causing activities and the lighter winds. The ozone levels will be lower today and Thursday before a brief bump up in the levels on Friday due to lighter and more favorable winds for transport from the Phoenix metro. Less favorable winds over the weekend mean lower ozone levels. Forecaster: S. DiBiase
