Forecast Discussion: A stationary front in the vicinity of Delaware tomorrow will bring widespread clouds and showers to the state, limiting ozone to the Good range. Particles will reach into the Moderate range, however, due to calm surface winds, locally recirculating air aloft, and the continued presence of smoke from Canadian wildfires. Fireworks celebrations will result in locally higher particle concentrations in the evening. **Extended forecast: Sunday will be a clear day with light and recirculating winds, which will allow ozone to rise well into the Moderate range. Lingering smoke from Canadian wildfires, in conjunction with formation of a sea breeze, will keep particles in the Moderate range. On Monday, light, onshore surface winds, increasing cloudiness, and evening rain showers will decrease ozone concentrations but they will remain in the Moderate range. As the wildfire smoke continues to dissipate, particle concentrations will drop to low Moderate range. -Eherts/DeBoe/Huff
