.DISCUSSION...High pressure ridging will be the prevailing
pattern well into the week. Drizzle, dense fog, and light
precipitation is possible for Del Norte & northern Humboldt
counties. A warming trend with light winds and morning valley fog
expected elsewhere this week. Rain potential builds at the end of
the weekend into next week as high pressure moves out of the
area, giving way to more normal conditions.
