Forecast Discussion: Warm and sunny on Sunday with increasing humidity as winds back to the southwest. Air quality will be in the Moderate range with ozone as the leading pollutant. For Monday, mostly sunny, hot and humid although increasing winds will allow for good ventilation and keep air quality within the Moderate range. A weak cold front is expected early Tuesday with improving air quality, particularly for fine particles, in its wake. However, peak concentrations of ozone will still reach the Moderate range at scattered locations in Delaware on Tuesday. -Ryan
