Synopsis and Discussion

Air quality levels have improved for Friday as a slow moving cold front moved to our southeast and the combined effect of showers and thunderstorms help cleanse the air. A maritime flow will continue for the next few days as a unique tropical situation begins to develop as two tropical systems, one being hurricane Humberto, churns just off the east coast. The other system is still developing but could end up strengthening and hitting the SC coast before sliding north. This could bring a lot of rain into the Triad early next week but as far as wind flow goes, both systems, along with a strong high over the northeastern US, will create a more maritime flow for the next few days. This maritime flow should help keep AQI levels in the upper GREEN range. (Bodenhamer)
