Forecast Discussion: A cold front will move through Delaware on Saturday morning, which will bring an end to this week’s period of unseasonably mild weather. Particle concentrations will fall as breezy winds arrive in the afternoon behind the frontal passage, with daily average concentrations in the Good range. It will be much cooler on Sunday, with gusty northwesterly winds and Good air quality. Another cold front will approach on Monday. Particle concentrations will rise in response to calm winds in the morning and warm air arriving aloft, but the daily average will remain in the Good range. The cold front and its associated low pressure system will bring cloudy skies and scattered rain showers to Delaware on Tuesday. Particle concentrations will reach the upper Good range due to high atmospheric humidity and light winds. -Huff
