Excessive Heat Friday Through the Weekend
A rapid warming and drying trend is in store this week with high pressure building over the Sacramento region, according to the National Weather Service.
High temperatures Friday into the weekend will increase the potential for poor air quality and for heat related illnesses for those exposed to prolonged time outdoors, especially the elderly, children and other sensitive groups. This includes your pets. Dry conditions with gusty north winds will increase the potential for fire starts as well.
A Spare The Air alert in the Sacramento region will be issued when the AQI for ground-level ozone pollution is forecast to reach 126 or above.

Air Quality Forecast and Weather Discussion
Monday, warm temperatures and sunny skies will increase ozone formation in the Sacramento region. Therefore, despite moderate onshore winds aiding pollutant dispersion, ozone levels will be Moderate. Tuesday, lighter daytime winds will reduce pollutant dispersion, and warm, sunny conditions will continue to support ozone formation. Furthermore, smoke from several wildfires throughout the region will increase particle concentrations and enhance ozone production. As a result, ozone levels will be Unhealthy for Sensitive Groups. Wednesday, as an upper-level trough of low pressure deepens over northern California, moderate southwesterly winds will aid pollutant dispersion and bring cleaner air into the Sacramento region. In addition, slightly cooler temperatures will reduce ozone formation. Therefore, ozone levels will be Moderate.
