Forecast Discussion: Tuesday will feel more like early May than late July as an unseasonably cool and dry air mass builds into Delaware behind Monday’s cold front. It will be mostly sunny with light northwesterly flow and Good air quality. **Extended Forecast: The weather will be just as nice on Wednesday and Thursday, with below average temperatures and low humidity. The center of surface high pressure will move overhead on Wednesday and then just offshore on Thursday, promoting mostly sunny skies and light winds. Formation of afternoon sea breezes both days will allow ozone and its precursors to accumulate along I-95 in northern Delaware, but the air mass in place will be clean enough to keep ozone in the upper end of the Good range. Particles will also remain in the Good range due to relatively low atmospheric humidity. -Huff
