Forecast Discussion: More summer-like weather will make a brief return this weekend as winds shift toward the south, bringing warmer and more humid air into Delaware. On Saturday, winds will remain onshore (southeasterly), which will bring clean maritime air into the state and limit particles to the Good range. Ozone will remain in the Good range as well due to a mix of sun and clouds. **Extended Forecast: On Sunday, a period of stagnation in the morning will allow particles to rise to the Good/Moderate threshold. Ozone will increase as well, but there will be enough clouds to keep concentrations in the upper end of the Good range. A cold front will move through Delaware overnight Sunday and usher in a cool and dry air mass for the beginning of the work week, with Good air quality for Monday. -Huff
