Forecast Discussion: Current Conditions: A strong area of high pressure continues to keep it's grip on the area this Thursday afternoon, and with the strong May sun, ozone levels are rising into the moderate range. Fine particulate remains in the good range due to the presence of very dry air, which is inhibiting it's formation. Tonight will be mostly moonlit as low temperatures fall back to near 60 degrees. *** Friday's forecast: Sunshine most of the day Friday with a warm afternoon. Temperatures rising into the middle and upper 80s, light southwest winds, along with smoke aloft, may send ozone concentrations to the middle part of the moderate range. Fine particulate will remain in the low to mid moderate range. *** Extended forecast: The Memorial Day weekend will start off on a partly sunny note, with afternoon and evening thunderstorms developing. The convection will keep ozone in the moderate range, and higher relative humidity will keep fine particulate in the moderate zone as well. The weather turns more unsettled as we move into Sunday and Memorial Day itself, with more clouds than sunshine, and the chance for a thunderstorm or two each of these days. Ozone will drop into the upper good range, but PM2.5 concentrations may remain moderate.---McAuliffe
