Moisture will increase as a low pressure approaches from the west, so ground level ozone will remain GREEN on this Thursday afternoon. Moisture associated with the low pressure system will gradually wane on Friday, and partial sunshine is expected during afternoon hours. Upper level trough remains over the region through the day, allowing for only slight increases to ozone concentrations during the day Friday. As a result, all zones are expected to remain CODE GREEN.
