Forecast Discussion: Current Conditions: At 2 p.m. EDT this Thursday afternoon, a warm and humid southwesterly flow of air continues to move across the region. With light winds and moderate humidity, both ozone and fine particulate are in the moderate range. Rather cloudy overnight with rain and a thunderstorm moving in late. *** Friday's forecast: A cold front coming eastward from the Ohio valley coupled with tropical moisture coming northward from Cindy will bring the area plenty of rain and a thunderstorm for the day Friday. The rain will also be heavy at times, with the rainfall washout and cloud cover keeping ozone and fine particulate down in the good range. Rain will end later on Friday night. *** Extended forecast: Breezy and cooler conditions will move in for Saturday, and last into the early part of next week, due to a broad based upper level trough of low pressure shifting the flow into the northwest. We will have times of clouds and sunshine Saturday and Sunday with temperatures several degrees below normal Sunday into Monday. With brisk northwest winds, fine particulate and ozone will remain in the good range through early next week. Later on next week, there will be a warming trend with ozone concentrations again on the increase.---McAuliffe
