Forecast Discussion: A warm front will lift north of Delaware on Thursday, bringing a return of Spring-like weather, with sunny skies and seasonable temperatures. A period of calm winds in the morning will allow particles to accumulate, and the arrival of warm air aloft will inhibit vertical mixing, permitting particle concentrations to reach just into the Moderate range, mainly in the northern part of the state. **Extended Forecast: The warm weather will continue on Friday, with temperatures near 70 °F. It will be cloudy with scattered rain showers throughout the day, however, and the chance for a thunderstorm. Gusty southwesterly winds will limit particle concentrations to the low Moderate range. A strong cold front will pass through the state on Saturday morning and usher in a much cooler and drier air mass, for a return to Good air quality. -Huff
