Forecast Discussion: Current Conditions: Dry weather continues across the region this Monday afternoon, with a weak area of low pressure just to our south producing plenty of cloudiness. With very light winds and little mixing, air quality is in the lower moderate range in most locations. Clearing will occur tonight as the low to our south pushes out to sea. *** Tuesday's forecast: A cold front is expected to approach us from the west on Tuesday, and bring some showers late in the afternoon and at night. Things will remain on the warm side, with afternoon temperatures in the middle to upper 70s. With light south to southwest winds, expect fine particulate concentrations to be in the moderate range once again. Showers may linger during the overnight period on Tuesday as well. *** Extended forecast: Slightly cooler air will move in behind the front on Wednesday. Clouds and perhaps a shower in the morning, then some sunshine will appear in the afternoon. Temperatures in the lower to middle 70s. Light winds will not allow a cleanout of PM2.5, so moderate levels of this pollutant will continue. The moderate air quality will last into Thursday with an area of high pressure building in. Better air quality may occur by Friday with winds from the south and southwest increasing ahead of a strong cold front which could bring rain and even a thunderstorm late Friday and Friday night. Much cooler air will sweep in on northwest winds for the weekend behind this front, with afternoon temperatures no better than the middle 60s. Things will be on the dry side over the weekend with mostly good air quality.---McAuliffe
