Forecast Discussion: Updated Friday, November 28, 2014 9:30 a.m. The beautiful weather will continue through this weekend with above normal temperatures and abundant sunshine. The winds will be relatively light along with the local dust causing activities. Therefore the forecasted PM10 AQI levels are in the upper good to low moderate range on the AQI scale through Monday. An upper level low pressure system will move into and through the area on Tuesday/Wednesday and bring the chance for some much needed precipitation. We’ll have to keep tabs on that weather system to see if there will be any impact with winds. Check back on Monday for an updated AQI forecast. Forecaster – S. DiBiase
