Forecast Discussion: Current Conditions: An area of low pressure continues to slowly move away from the region this Wednesday afternoon. On the western fringes of this low, there can still be a shower pop up late this afternoon into this evening. With very light winds continuing, most locations are measuring fine particulate in the moderate range. Moderate concentrations of PM2.5 seem to be a good bet through at least Thursday as high pressure builds in, winds are light to calm, and temperature inversions develop. Turning out partly cloudy tonight with areas of fog later on. PM levels will continue in the moderate zone. Lows mainly in the middle 50s overnight. *** Thursday's forecast: High pressure will bring more in the way of sunshine for the area on Thursday, but with minimal mixing in the boundary layer, moderate air quality should continue. Afternoon temperatures should rise into the middle 70s. Mostly clear Thursday night with lows in the lower to middle 50s. *** Extended forecast: Winds will shift into the south and be on the increase on Friday. How much improvement there is in air quality will depend on how strong winds get in the afternoon. For now, we will continue with a low moderate average for the day, with highest levels of PM in the morning. A few more clouds might knock temperatures back down to close to 70 degrees. Rain and a thunderstorm is then likely Friday night into Saturday morning as a strong cold front moves through. Gusty northwest winds will then move in behind the front Saturday into Sunday, bringing good air quality, but also cooler temperatures. Highs by Sunday might not get too much above 60 degrees despite the return of some sunshine. As we look into the early part of next week, the weather pattern will be a progressive one, with a series of weather systems coming southeastward from the Great Lakes. These systems should result in good atmospheric circulation with low levels of PM overall. Temperatures will average slightly below early October levels as well.---McAuliffe
