Saturday is a Code Orange Air Quality Action Day for particulate matter in Delaware as light to moderate southeasterly winds recirculate smoke from the Canadian wildfires into Delaware. Also high pressure, warm temperatures and partly sunny skies will aid in ozone development pushing air quality to levels unhealthy for sensitive groups for particulate matter and high to moderate for ozone.

Extended Forecast:

Sunday, scattered showers and thunderstorms Saturday night are expected to enhance atmospheric mixing leading into Sunday, while partly to mostly cloudy skies during the day limit ozone formation. However, light southerly to southeasterly winds will keep a thin plume of smoke across the region, with Moderate AQI levels anticipated for both ozone and PM2.5.

Monday, scattered showers and thunderstorms will continue to promote atmospheric mixing, while partly cloudy skies hinder ozone development. Therefore, AQI levels are anticipated to be low-Moderate for ozone and PM2.5.
