Forecast Discussion: Current Conditions: At 2 p.m. EDT this Monday afternoon, a dying cold front was approaching from the Ohio valley, with only a few clouds, but no shower activity. Very light winds and limited mixing are producing fine particulate levels in the moderate range. With no wind influence from Jose over the next couple of days, surface winds will continue to be light, with limited dispersion of PM2.5, so moderate air quality is likely to continue. Expect partly cloudy and mild conditions for tonight with low temperatures only falling to the lower 60s. *** Tuesday's forecast: Tuesday will bring clouds and some sunshine with another warm afternoon with the mercury climbing to around 80 degrees. Limited mixing and a strong morning inversion will maintain moderate levels of PM2.5, with the highest readings coming in the morning. Another partly cloudy and mild night is in store Tuesday night with lows only near 60 degrees. *** Extended forecast: An extensive ridge of high pressure will build over the eastern part of the nation later on this week, with temperatures averaging well above late September normals. Very limited low level mixing and stagnation will bring continued moderate concentrations of fine particulate to the area.---McAuliffe
