Forecast Discussion: Current conditions: High pressure directly overhead this Wednesday afternoon has brought sunshine and very light winds to the area. The lack of circulation has caused fine particulate to rise into the lower moderate range this afternoon. Mixing is expected to be limited again tonight and Thursday. *** Thursday's forecast: Near calm winds and a moderately strong morning inversion Thursday will send fine particulate concentrations well into the moderate range. The highest numbers are expected during the morning hours, as the inversion may break somewhat in the afternoon. *** Extended forecast: Fine particulate levels will remain well into the moderate range Friday with precipitation not arriving until the nighttime hours with winds remaining rather light. Much better air quality is expected Saturday as low pressure affects us with periods of rain mixed with a bit of snow. Winds will also increase around the low and will remain brisk Saturday night into Sunday as the low moves off to the northeast. So, air quality should be in the good range over the weekend. Increases in fine particulate are possible again early next week as high pressure reestablishes itself.---McAuliffe
