Forecast Discussion: Current Conditions: At 2 p.m. EDT this Wednesday afternoon, hot and humid conditions persist across the region. A cold front moving through during the early morning hours on Thursday will bring a cleaner air mass in behind it, resulting in lower concentrations of both ozone and fine particulate for the late week period. Tonight, a cold front will move through later on, and there will also be a shower or thunderstorm in parts of the area. Fine particulate will remain up into the moderate range. *** Thursday's forecast: A cleaner air mass will be moving into the area during the day Thursday with increased mixing and lower levels of ozone and fine particulate. Afternoon temperatures will be in the middle 80s with ozone and fine particulate improving to the good range. Mostly clear and comfortable Thursday night with lows in the lower to middle 60s. *** Extended forecast: Good air quality will continue for the day Friday with a clean west to northwest flow continuing. Both ozone and PM2.5 will continue to be held in check by the dry air present. High temperatures will again reach into the middle 80s with plenty of sunshine. A weak frontal boundary will move through sometime Saturday afternoon, and bring a shower or two with it. Fine particulate may move into the moderate range in a few locations, while concentrations of ozone remain low. High pressure will bring mainly dry and seasonably warm weather for Sunday into Monday of next week, with fine particulate and ozone elevating into the moderate range again by Monday. A cold front then moves through the region early Tuesday, and this will bring in cooler air for the middle of next week with improving air quality.---McAuliffe
