Forecast Discussion: Upper Moderate ozone air quality is possible tomorrow, Thursday, in isolated areas along the I-95 corridor as a front stalls and weakens along the same area. The convergence and stagnation provided by the front in conjunction with westerly upper level transport will be enough to raise ozone concentrations in isolated locations. On Friday, clean-out is expected during the afternoon, but not before recirculation of the same airmass from Thursday leads to Moderate ozone air quality for locations west of the Bay. On-shore flow on Saturday will clean the region out and lead to Good air quality. - MDE
