Forecast Discussion: A weak “back door” (southward-moving) cold front will move into Delaware on Tuesday, promoting mostly cloudy skies and the chance for an isolated shower in the afternoon. Despite several days of warm and stagnant conditions, particle concentrations have been slow to rise across the state. Very light to calm winds in the morning and convergence ahead of the slowly progressing front will support low Moderate particle concentrations on Tuesday, however. The light winds and periods of sun will favor ozone formation as well, but there will be enough clouds to limit ozone to the upper Good range. **Extended Forecast: Sustained north to northeasterly flow on Wednesday and Thursday will keep particles in the upper Good range. **This is the last ozone forecast for the 2014 season. Ozone forecasts will resume on May 1, 2015. -Huff
