June 12-17, 2019 A series of small high pressure ridges and troughs ripple their way east as a large high pressure cell approaches from the west. This ongoing high pressure pattern will continue the clear, sunny, blue skies pattern but expect temperatures to be a bit cooler with the return of the coast marine influence starting Wednesday. The return of the marine layer and onshore flow will cool record high temperatures for coastal areas but temperatures will still be above average. This marine influence will not reach the inland areas until Thursday or Friday so Inland areas will remain hot today but can expect a drop in the temperatures by end of the week. Expect AQI for Ozone to breach into MODERATE at the Hollister, King City, Salinas, Santa Cruz and Pinnacles monitoring sites during the peak temp periods. Likewise, the increased warming will prime our soils so the King City and Hollister areas can expect potential increases in PM10. For this week, expect AQI of PM2.5 in the GOOD in all categories and all areas of Monterey, San Benito and Santa Cruz Counties except Santa Cruz may experience periods of MODERATE.
