Forecast Discussion: Forecast Discussion Nov 19 to 24, 2014: An unsettled pattern remains in place through Saturday as a series of weak Pacific storm systems move through the Central Coast, bringing with them on and off chances of light showers through the period. The continuing progressive pattern should be good for air quality with AQIs for PM2.5, PM10 and ozone expected to remain in the GOOD air quality category for most areas. However, with cool nights settling in the San Lorenzo Valley, AQIs for PM2.5 may reach the MODERATE category due to residential wood smoke. However, no exceedances of the federal 24-hour average federal air quality standard for PM2.5 are expected at this time. Please note, due to recent rains CAL FIRE has lifted its SUSPENSION of OPEN BURNING in the State Responsibility Areas of Santa Cruz, Monterey and San Benito Counties. The ban has been in effect since last spring. As a reminder, the backyard burn season doesn’t begin until December 1st.
