Forecast Discussion: We are beginning our ozone forecasting for 2015. These forecasts will be available daily from today until mid-September 2015. So without further ado... *** Current Conditions: As of 2 PM on Monday, mostly cloudy skies persist over the region as a weak disturbance moves in over southwestern PA. This system is triggering light showers as it tracks to the south and east. Over our area, winds remain out of the northwest, which is why temperatures are rising out of the 40s. The cloud cover today is keeping ozone within the good threshold. Expect more good conditions tomorrow as it remain cloudy and seasonably cool. *** Tuesday's Forecast: So for Tuesday, expect mostly cloudy skies to persist across the region as an area of high pressure remains stationed off to our west. The clockwise rotation around the high will keep our flow out of the north, resulting in temperatures only rising into the 50s. The combination of the cool and dry conditions along with the cloud cover over the region will help to hold ozone concentrations within the good threshold. --Nolan
