Forecast Discussion: It will be a warm and sunny summer weekend across the State of Delaware, but with more comfortable humidity. Particles will remain in the Good range both weekend days due to the lower humidity. On Saturday, ozone will rise well into the Moderate range under full afternoon sun and light northeasterly surface winds. The flow aloft will turn onshore (southeasterly) on Sunday, which will push ozone lower into the Moderate range. Atmospheric humidity will jump back up again on Monday ahead of a weak cold front that will stall to the west of the forecast area. A period of calm winds in the morning and plenty of afternoon sun will allow ozone to rebound back up to the top of the Moderate range, while particles will also increase but remain in the Good range. **Extended Forecast: The weak front will slowly approach the state on Tuesday. Warm and humid weather will continue. Recirculating flow aloft and at the surface will push ozone to the very top of the Moderate range, while particles will rise to the Good/Moderate threshold. -Huff
