Forecast Discussion: Current Conditions: At 2 p.m. EDT this Thursday afternoon, there are breaks in the clouds across the area, with ozone levels rising well into the moderate range, and fine particulate is also moving into the moderate zone as well. Low pressure is developing across the Ohio valley, and this will cause our weather to be unsettled from Friday afternoon into Saturday morning as it slowly moves to the east. Mostly cloudy and humid tonight with nothing more than a shower. Lows in the middle and upper 60s. *** Friday's forecast: Rather cloudy and humid for Friday with showers and thunderstorms coming in by the afternoon and continuing Friday night. Ozone levels will be limited by the considerable amount of cloudiness, and northeasterly winds will even knock fine particulate back to the good range. *** Extended forecast: Rain will start Saturday, then breezy and unseasonably cool later in the day with a little sunshine returning. Sunshine for the most part on Sunday with a nice breeze, then high pressure will provide dry weather for the early part of next week with temperatures slowly returning to normal. With the rise in temperatures, both ozone and fine particulate will have the chance to rise by the middle of next week.---McAuliffe
