Forecast Discussion: For July 30-Aug 2: Expect GOOD air quality in most of Puget Sound. The foothills of the Cascades may see elevated smog due to high temperatures, air quality may reach "unhealthy for sensitive groups." If you have asthma or other health concerns, consider hiking or being outside in the earlier hours of the day (if you will be in the Cascade Foothills). Sara Harrold, Agency Forecaster
