Onshore flow persist across the region Sunday afternoon and will 

continue to bring higher humidities to the coast along with cooler

temperatures as the marine layer deepens slightly. As the onshore

winds increase, they will result in a cooling trend across the 

interior throughout next week, but temperatures will remain above 

average in these areas. Dry weather continues into next week, 

especially for the interior.





...Discussion from SFOFWFEKA...



The ridge has been pushed east as an upper level low moves toward

the area. A weak front associated with the low will bring 

moisture to the area, with some drizzle at the coast. The higher 

terrain will keep the moisture confined mostly to Del Norte, 

Humboldt, and western Mendocino with minimum RHs for the interior 

remaining in the 20s to 30s into mid-week. However, some showers 

may affect the higher terrain of northern Trinity County this 

afternoon and perhaps tomorrow. Maximum temperatures in interior 

valleys remain mostly in the mid to upper 80s. Another ridge will 

move into the area mid-week bringing more warm and dry conditions 

for both coastal and interior areas.
