September 18-25, 2018 The present upper level trough moves inland along northern CA causing seasonably cool conditions, onshore flow and a morning marine layer along the coast. Expect these conditions to continue during the week. Onshore flow diminishes by week end as high pressure builds allowing for warmer temps this weekend. Wildfires continue in Northern CA and the Pacific Northwest. Smoke forecast shows smoke from the Natchez fire in the Klamath National Forest and the Delta Fire in Shasta Trinity National Forest push south along the California coast passing our area Wednesday and Thursday. This smoke is expected to remain in the upper levels away from ground level breathing space but that could be altered depending on meteorological conditions. Overall air quality is expected to remain GOOD in most areas but may periodically slip into the MODERATE category for PM 2.5 depending on wind direction and other meteorological conditions. Ozone and PM10 levels are also expected to be in the GOOD range during this week.
