Forecast Discussion: Current conditions: At 2 p.m. EDT this Friday afternoon, a large ridge of high pressure continues to build over the area. With a drier west to northwesterly flow, ozone and fine particulate are down into the good range for the most part. High pressure will influence the local weather through early Sunday, with a weak disturbance coming through late Sunday into Sunday night projected to bring a shower or thunderstorm. So, for tonight, we can expect a mostly clear and mild night with low temperatures in the lower and middle 60s. *** Saturday's forecast: Sunshine for the most part Saturday, and with the full sun and light winds, ozone may ramp up to the lower moderate range. The light winds will also act to prevent mixing to the point where fine particulate, while falling some in the afternoon, ends up averaging over the moderate threshold. Afternoon temperatures rising into the middle and upper 80s. *** Sunday's forecast: A weak disturbance will affect us late in the day Sunday into Sunday night with a thunderstorm in parts of the area. More cloudiness on Sunday may send ozone down to the top end of the good range, while fine particulate remains moderate with the higher humidity. *** Monday's forecast: Periods of clouds and sunshine, warm and humid for Monday. A thunderstorm can again develop in the humid air, and this might keep ozone down at the upper good range while fine particulate remains moderate. *** Extended forecast: Mostly dry weather with above normal temperatures for the early to middle part of the week, with mostly moderate air quality, but then a cooldown is likely for the latter part of the week, just in time for the start of September with a clean northwest flow and good air quality returning.---McAuliffe
