Forecast Discussion: At 2 p.m. EDT this Thursday afternoon, warm and humid conditions prevail across the region with partly sunny skies. A thunderstorm can pop in parts of the area this afternoon into this evening. Friday, a cold front will be pressing south and east of the area, weakening as it does so. The influx of clean and drier air from the northwest will bring ozone down to the good range. The weekend looks dry and warm as a strong ridge of high pressure moves over the Mid-Atlantic states. Ozone will be on the rise over the weekend, possibly reaching the moderate range by Sunday. The next chance for thunder will come early next week.---McAuliffe
