May 27 to June 1 – A late season low pressure system will remain over the Central Coast through Sunday leading to partly cloudy skies, below normal temperatures and exceptional dispersion of air pollution. However, a gradual warming trend will then set in as a ridge of high pressure builds in over the area. Reduced dispersion from this increasing stability may cause daytime ozone concentrations in South San Benito County to rise into the low MODERATE category of EPA’s Air Quality Index (AQI) beginning on Sunday. Also, daytime NW winds with speeds gusting above 20 mph in the Salinas Valley may increase PM10 concentrations into the MODERATE category of the AQI daily through the forecast period. All other measured pollutants in all other areas within the North Central Air Basin are expected to remain in the GOOD category of the AQI.
