Forecast Discussion: Current conditions: An area of high pressure is sliding off to our south this Monday afternoon. Since this high is not centered over us, breezy conditions continue, and fine particulate remains in the good range as a result. Over the next 24 hours, winds will turn into the southwest, and bring in an influx of milder air. Tonight will bring a mostly clear sky, and with less wind, temperatures will fall to the middle to upper 20s in the colder spots. *** Tuesday's forecast: Sunshine for the most part Tuesday with a milder afternoon. While fine particulate will rise some with the warmer air, levels will stay in the upper good range. Afternoon temperatures will reach into the middle 50s. A cold front will pass later on Tuesday night, but not have much more than a rain shower with it. *** Extended forecast: Turning cooler as we move into Wednesday with sunshine returning. An influx of clean air will send fine particulate further down into the good range with highs remaining in the middle to upper 40s. High pressure controls the weather for Thanksgiving Day into Friday. PM2.5 levels will remain in the good range Thursday, then perhaps rise some into the lower moderate zone by Friday. The next cold front arrives sometime Saturday with a few showers.---McAuliffe
