Forecast Discussion: Current conditions: At 2 p.m. EDT this Friday afternoon, a large area of high pressure was building into the area from the Ohio valley. A northwesterly flow bringing in drier air has acted to lower humidity. Fine particulate and ozone will be coming down into the good range this afternoon as a result. Tonight will be mostly clear with low temperatures in the middle and upper 60s. *** Saturday's forecast: We will have sunshine for the most part for the day Saturday with a very warm afternoon, and temperatures again up close to 90 degrees. With full sun, ozone levels will move into the middle moderate range, but with the dry air in place, PM2.5 levels will remain in the upper good range. *** Sunday's forecast: More sunshine than clouds for the day Sunday, and it will feel more humid by the afternoon. Highs will reach the upper 80s, and with light winds, ozone production may support low moderate readings. Fine particulate will also go to the lower moderate range with humidity increases. *** Monday's forecast: Periods of clouds and sunshine, warm, and humid for the day Monday with the chance for a pop up thunderstorm with slightly cooler air coming in aloft. Highs will reach the upper 80s, and ozone formation might be limited to the bottom part of the moderate range. Fine particulate will remain moderate. *** Extended forecast: Above normal temperatures will continue through the middle of next week, with scattered convection possible again Tuesday which will limit ozone formation. A cold front could move across the state by the middle of the week, and could cool things down with good air quality by next Thursday, the start of September.---McAuliffe
