Fires across the Aberdeen Proving Grounds look to be contained at this point in time. The situation will need to be monitored closely over the next several days for potential flair ups but for now the impacts on air quality look to be limited. Southerly flow will persists over the next several days providing unseasonal warmth and elevated dew points. Additionally, the development of overnight and early morning surface inversions will result in fine particulates pushing into the low Moderate range along the I-95 corridor for much of this week. By Friday, high pressure will move to our north as a weak frontal system passes south of the area. Lowering dew points and the impacts of a cleaner Canadian air mass will bring the return of Good air quality across the state.
