Discussion for July 31 to August 5 – A summer monsoonal flow pattern is in place as high pressure centered over the 4-Corners states combined with an offshore low rotate subtropical moisture and instability into our area. This will result in high clouds, cooler temperatures and somewhat muggy conditions into the weekend, until generally clear skies and warmer temperatures return next week. The usual night and morning low clouds and fog can be expected to lurk along the coast through the forecast period. The pattern should maintain adequate instability to prevent air pollution from building up resulting in air quality levels for ozone, PM10 and PM2.5 generally persisting in the GOOD air quality category of EPA’s Air Quality Index. Please note, due to the long-term drought, CAL FIRE has suspended open burning in all State Responsibility Areas of Monterey, San Benito and Santa Cruz Counties. During these extremely dry conditions, residents are also cautioned about the high risk of causing a wildfire when using any ignition source near dry grass and brush.
