Air Quality Forecast

July 2 – July 6: Low-pressure to the north has kept things cool over the last week and is expected to continue through Thursday.  Beginning on Friday, high pressure will take over and warm things up a bit.  Zonal flow will keep winds onshore, which despite the warmup inland, should keep the marine stratus around, effectively moderating temperatures at the coast. Temperatures will range from the low-50s to the low-70s at the coast and low-50s to mid-90s inland. Seasonal temperatures will keep ozone production at normal levels for this time of year; therefore, ozone AQIs will remain GOOD.  Decent wind speeds in the Salinas Valley could bring PM10 AQIs to MODERATE.  As low pressure remains, expect PM2.5 (smoke) AQIs to remain GOOD.  Building high-pressure this weekend will reduce ventilation and we could see MODERATE PM2.5 AQIs.
