Forecast Discussion: Current Conditions: A weak area of low pressure was moving through the eastern part of the Ohio valley at 2 p.m. EDT this Thursday afternoon. Light rain and rain showers were occurring out ahead of this system. The heavier showers have kept PM2.5 levels down in the good range, but levels will be on the increase over the next 24 hours. Showers will continue tonight, and increasing levels of low level moisture will push fine particulate into the lower moderate range later on. Lows will drop into the upper 40s. *** Friday's forecast: A shower will linger early on Friday, then some sunshine will appear in the afternoon as temperatures recover back to near 70 degrees. Light winds and limited mixing will result in fine particulate being elevated, but overall averages for the day will average in the upper good range. Mostly clear and cool Friday night with lows in the middle 40s. *** Extended forecast: High pressure will bring nice weather early on in the period, but a strong area of low pressure coming out of the nation's midsection will result in unsettled weather returning Sunday night into Monday. Winds will remain on the light side with little mixing on Saturday and fine particulate will rise into the low moderate range. As the high moves off to the east Sunday, low pressure will then approach from the west. This will strengthen the pressure gradient over us, bringing lower PM2.5 values. Concentrations of this pollutant should remain low Sunday night into Monday as heavier rainfall washes out the air mass over us. Towards the middle of next week, low pressure over Hudson Bay, Canada, will bring a west to northwest flow to the region, resulting in continued good air quality, but also temperatures a little below normal.---McAuliffe
