Forecast Discussion: Current Conditions: A cold front extending from the northeastern to the southwestern part of Pennsylvania is slowly sinking southward this Wednesday afternoon. Light winds in the vicinity of the front in addition to increased low level moisture have resulted in PM2.5 concentrations well into the moderate range. The cold front will shift to our south tonight, resulting in much colder air moving back in later tonight into Thursday. The front will also stall not too far to the south, resulting in waves of low pressure riding along it. For us, that means any rain will turn back to sleet and snow later tonight into the day Thursday. *** Thursday's forecast: Snow will continue into the early afternoon hours of Thursday and accumulate a total of 4 inches in the north to as much as 8 inches in southern parts of the partnership area. Northerly winds and moderate rates of snowfall will send fine particulate concentrations downward into the good range. Temperatures Thursday will hold in the middle and upper 20s. Clearing and rather cold Thursday night with lows in the single digits in the coldest spots. *** Extended forecast: High pressure coming out of the Tennessee valley and shifting eastward will bring more tranquil weather to the region over the weekend. Things will remain on the cold side for Friday in spite of sunshine and light winds. PM levels will average in the lower moderate range. A couple of weak disturbances will move through over the weekend, and perhaps reduce PM the good range for a brief period, but overall air quality will remain moderate into the early part of next week as temperatures also moderate back closer to normal March levels.--McAuliffe
