Forecast Discussion: Updated Tuesday, May 5, 2015 9:25 a.m. Widespread rains yesterday have added more moisture to ground surfaces which will help extend the amount of time it takes for things to dry out. Correspondingly the PM10 levels are low and will remain relatively low for this time of year. Another upper level low pressure system from the Pacific Northwest will move into the area later in the work week and bring another chance for more precipitation. The combination of low pressure systems this week will keep the temperatures below normal as well as the ozone levels in the good AQI category. Enjoy the comfortable temperatures and good air quality. Check back on Wednesday for an updated air quality forecast. Forecaster – S. DiBiase
