Today’s Forecast:
Thursday, July 16 is a Code Red Air Quality Action Day for Delaware. Westerly to west-southwesterly winds ahead of a cold front will transport smoke from Canadian wildfires into Delaware throughout the afternoon. This smoke, combined with mostly sunny skies and temperatures in the mid- to upper-90s, will enhance ozone formation. Furthermore, a dense plume of smoke will arrive in the late evening as the front passes over the state. As a result, AQI levels are anticipated to be Unhealthy for PM2.5 and Unhealthy for Sensitive Groups for ozone.

Extended Forecast:

Friday, July 17 is a Code Red Air Quality Action Day for Delaware. Light northerly winds behind the departing front will carry dense wildfire smoke into the First State, increasing particle concentrations throughout the day. Furthermore, pollutant carryover from the previous day will be high. Thus, AQI levels are anticipated to remain Unhealthy for PM2.5 and mid-Moderate for ozone.

Saturday, a passing warm front will shift winds to southerly to southwesterly, which will gradually disperse dense wildfire smoke. In addition, scattered thunderstorms associated with the front will support mixing. However, a morning inversion will trap smoke near the surface, and pollutant carryover for the first half of the day will remain high. As a result, AQI levels are anticipated to be Unhealthy for Sensitive Groups for PM2.5 and low-Moderate for ozone.
