Synopsis and Discussion

Particle pollution levels currently reside well within the Code GREEN range today as gusty westerly winds have generated decent low-level dispersion of pollution particles. Winds should begin to lessen by sunset, and the nocturnal temperature inversion is expected to be strong enough to enhance particulate matter concentrations overnight. With New Year's celebrations leading to widespread use of celebratory pyrotechnics around the midnight hour, particle pollution levels may approach Code Orange AQI for a few hours before slowing dissipating through mid-morning tomorrow. Even if hourly particle pollution levels drop to Code GREEN by Thursday afternoon, the daily average AQI will likely remain Code YELLOW. As an area of low pressure approaches from the west on Friday, increasing clouds through the day should trap pollution particles underneath the cloud deck to warrant Code YELLOW AQI. Air quality levels should remain Code YELLOW into Saturday as chances of rain increase with the area of disturbed weather transiting the region. (Payne)
