Forecast Discussion: Current conditions: At 2 p.m. EDT this Thursday afternoon, high pressure was retreating off of the east coast, making way for unsettled weather to move in from the Midwest. Enough mixing exists to keep fine particulate concentrations low. Rain and even a thunderstorm will continue tonight as low pressure slowly moves through the Ohio valley. *** Friday's forecast: Periods of rain will continue through the day Friday, with low pressure over eastern Ohio transferring it's energy to a new low developing near the Delmarva peninsula. Rainfall should continue to be heavy enough to keep fine particulate levels low, with the heaviest rainfall coming during the morning. Rain will taper to showers late Friday afternoon and Friday night as low pressure moves off the east coast. *** Extended forecast: Rather cloudy, brisk and cooler for Saturday with a north to northwest flow keeping particle concentrations on the low side. Sunday will bring clouds and perhaps some sunshine as high pressure briefly builds in from the west. Clouds will increase Monday out ahead of the next storm system slated to bring us another round of rain Monday night into Tuesday. The progressive nature of the weather pattern in the long range period will maintain good air quality and keep PM from building up for any length of time.---McAuliffe
