Forecast Discussion: A late summer period of well above average temperatures will impact Delaware this week, with some relief possible by Friday. Hot, humid, and stagnant weather will be the rule, allowing for deteriorating air quality as early as Tuesday. For Monday, mostly cloudy skies in the morning will give way to clearing in the afternoon. There will be sufficient cloud cover through lunchtime to limit ozone to the Moderate range. Particles will reach the low Moderate range due to increasing humidity, light winds, and the arrival of remnant smoke from the western U.S. wildfires. **Extended Forecast: Code Orange (Unhealthy for Sensitive Groups; USG) ozone is possible on Tuesday in response to mostly sunny skies and light and recirculating winds. USG ozone is also possible on Wednesday, but there is some uncertainty about a possible disturbance aloft that may provide enough cloud cover to limit ozone to the Moderate range. Particles will continue to increase higher into the Moderate range both days. -Huff
