Forecast Discussion: Current conditions: Mostly sunny skies and warm air are sending ozone well into the moderate range in most locations this Thursday afternoon. Mostly moonlit tonight as low temperatures fall back to near 60 degrees. *** Friday's forecast: Periods of clouds and sunshine and continued warm on Friday, and with light southwest surface winds, ozone and fine particulate will go into the moderate range as temperatures move into the middle and upper 80s. *** Extended forecast: Turning rather cloudy, warm, and humid Saturday with showers and a thunderstorm developing. Ozone and fine particulate will be no higher than the lower moderate range. The weather turns more unsettled Sunday into Memorial Day with more clouds than sunshine and the chance for showers and a thunderstorm each day as a slow moving area of low pressure affects the northeastern part of the nation. Ozone and fine particulate will average in the upper good to lower moderate range.---McAuliffe
