Synopsis
Dry weather with warm interior daytime temperatures are forecast through Monday. Some coastal low clouds and fog will burn off by late morning. Otherwise, expect abundant sunshine. A weak frontal system will clip the northern portion of the area, bringing a chance of light rain to Del Norte County Tuesday night and early Wednesday.

High pressure east of our area will persist through Monday. This is bringing abundant sunshine and dry conditions along with warm temperatures. While the marine stratus continue to expand with multi size scale eddies along the coast keeping the shoreline with low clouds moving in and out. For the rest of the evening, low clouds and areas of dense fog are expected to redevelop, mainly for N Humboldt and Del Norte Coasts. The stratus and fog will gradually have a stronger presence over the waters and coast into mid next week with onshore flow becoming more zonal as an upper- level trough digs south the Pacific NW coast. A shortwave will , bringing a chance of light rain or drizzle to portions of Del Norte County Tuesday night and early Wednesday. Rainfall amounts are expected to be light, with up to five hundredth of an inch on some windward facing terrain. Temperatures will trend down on Tuesday and Wednesday, only bounce back to above normal Thursday and Friday with E Pacific ridge building into the NW Coast. Ensemble and deterministic guidance are showing a broad upper level trough digging south from NE Pacific into the Pacific NW later next weekend.

Marine
Northerly winds will continue to weaken into the middle of the week. All small craft advisories have expired; however, in the far west and northwest of the northern outer waters, there is a small coverage area of short-period seas. Those will subside overnight. A series of mid period NW swells will propagate through the waters throughout this work week, peaking at about 4 feet tomorrow morning and 8 to 9 feet Wednesday night. The northern outer waters will be clipped by a passing low pressure system moving onshore to the north of our coastal waters by Wednesday morning. This system will weaken the northerlies further and turn them southerly for a short period. Northerly winds will redevelop and strengthen Wednesday afternoon and into next weekend as another high pressure system pushes east.

.EKA WATCHES/WARNINGS/ADVISORIES... CA... None. NORTHWEST CALIFORNIA COASTAL WATERS... None.
