Forecast Discussion: Updated Friday, February 12, 2016 9:50 a.m. The unseasonably warm temperatures will continue along with the abundant sunshine as high pressure dominates the area. The only minor change will be a trough that quickly moves through the area over the weekend and brings a little bit of high cloudiness late Saturday through early Sunday. Not much change in the temperatures is expected. Air quality wise, Hidden Valley once again has elevated PM10 levels this morning thanks to a strong temperature inversion and local dust causing activities. Unfortunately more of the same is expected over the next several days therefore the Hidden Valley PM10 forecasts have been increased into the low/mid range of the moderate AQI category for today and through Monday. Stanfield will also be in the moderate AQI category today before dropping back into the good category over the weekend. The remainder of the PM10 monitoring locations are expected to remain in the good AQI category. The ozone levels will remain in the upper range of the good AQI category and PM2.5 levels are expected to be slightly lower (i.e. good). Forecaster: S. DiBiase
