Forecast Discussion: Current Conditions: The current radar shows a band of showers and some embedded thunderstorms moving into the region this Tuesday afternoon. Winds are also increasing out of the northwest with the passage of a cold front. The increase in mixing has lowered fine particulate some, but most locations still average in the moderate range. Tonight, as the front passes, winds will become light once again, so fine particulate concentrations will remain in the moderate zone. Low temperatures in the lower to middle 50s. *** Wednesday's forecast: Morning cloudiness will yield to some sunshine by Wednesday afternoon. Very little mixing and light winds will result in fine particulate mostly at moderate levels. Temperatures will reach into the lower 70s. Partly cloudy Wednesday night with a continuation of moderate air quality. *** Extended forecast: High pressure building in on Thursday will provide for a tranquil weather day, but with moderate levels of PM. Becoming breezy on Friday with showers and a thunderstorm in the afternoon as a strong cold front comes out of the Ohio valley. The increasing winds and rain may bring PM levels down to the good range. The weather pattern then takes a cooler and more progressive turn over the weekend into the early part of next week. Brisk and much cooler Saturday with a lingering shower possible early, but with good air quality. Temperatures will hold in the upper 50s. Another front will approach on Monday, bringing another chance for showers. Increasing winds and cooler temperatures over the weekend into next week will promote good air quality overall, with temperatures slightly below normal for early October levels.---McAuliffe
