Air Quality Forecast

April 30 – May 4: A ridging pattern through the end of the work week will allow for a buildup of marine stratus that should cool things down at the coast while keeping inland temps elevated. Beginning Saturday/Sunday, low-pressure will begin to move into the region and bring a cooling trend and chances of precipitation. Precipitation chances will last through Monday; however, they will not be impactful with totals under 0.1”. Temperatures will range from the high-40s to the low-70s at the coast and high-40s to mid-80s inland.  Ozone levels should remain below State standards; therefore, ozone AQIs will remain GOOD. Moist conditions will keep PM10 (dust) AQIs in the Salinas Valley at GOOD as well. As low-pressure develops, expect ventilation to improve and maintain PM2.5 AQIs (smoke) at GOOD levels.
