Forecast Discussion:
Anticipate scattered showers and thunderstorms to develop once again later today before a downtrend in storm chances begins Wednesday with just slight chances each day through Saturday. With a decline in storm activity and cloud cover, there will be an increase in temperatures with above normal highs beginning Thursday.
Peak 8 hour average Ozone is expected to be in the Good range today aided by the cloud cover. On subsequent days, less cloudiness is expected and daily Ozone readings are expected to trend upward going from low Moderate Wednesday to upper Moderate Friday and Saturday.
Daily average Particulates are expected to remain in the Good range aided by recent rains and warm season ventilation.
