Marine Weather and Tide Forecast for Little River, CA

KEY MESSAGES
- Increasing north winds across the area into the weekend.

- Cooler temperatures Friday and Saturday.

- Warming trend Sunday into next week.

SHORT TERM
(This afternoon through Saturday)...
Most of the interior valleys are expected to see temperatures only warm into the upper 60s to mid 70s. Lake county may reach the upper 70s in some locations, especially south of Clear Lake. The coast is showing scattering cloud coverage allowing temps warm to around 60. Thursday, a brief ridge builds in rebounding temperatures back into the 80s in most of the interior valleys.
Gusty north to northwest winds are expected as well, enhancing upvalley winds. Thursday night into Friday morning the winds at higher terrain will remain elevated. Friday night into Saturday a weak front to the north of the area will increases the northerly winds and cloud coverage. At this point, rain is not expected (<20% of 0.01") as the main influence of the front will be felt in Oregon. However, this front will cool temperatures for Friday with even more additional cooling Saturday. Highs on Saturday will struggle to break 70F with a 20% chance of >70F in the warmest valleys while other areas remaining in the upper 50s and 60s.
Saturday, the strongest winds are predicted as a building high pressure system to the west interacts with a low pressure center to the east. Many areas are expected to see gusts over 30 mph and there are expected to be some areas with gusts over 40 with a 30-40% likelihood for exposed areas. The increased mixing and lack of a marine inversion should bring plenty of sunshine to the coast.

LONG TERM
(Sunday through Tuesday)...
Sunday high pressure starts to build back into the area on Sunday. Northerly winds remain strong as the system that moved by to the north of the area drops into the Great Basin. These may weaken slightly in areas away from the coast and in E-W orientated valleys. These winds will advect marine air, keeping the areas near the coast and up the river valleys cooler than areas farther inland. Highs away from the coast should warm into the 70s again to end the weekend. A warming trend is forecasted early week with highs finally warming back into the upper 80s to low 90s inland.
The strong northerly winds are finally expected to diminish starting Monday and Tuesday, but remain breezy. Overnight the winds turn offshore and may help keep the coastal clouds out of the area. Northerly winds calm much more Wednesday through the end of next week.

AVIATION
Mainly VFR conditions and breezy NW winds across all terminals this afternoon. Surface winds are expected to ease after 14/03Z, and become light N winds to very light and variable. HRRR model guidances suggest low clouds developing around the Humboldt Bay and vicinity after 14/04Z. There is a 25-35% chances of MVFR to IFR clouds impacting the coastal terminals tonight, especially at ACV. Any low clouds is anticipated to lift and clear out after sunrise. Surface winds are forecast to increase late Thursday morning, with gusty winds up to 25 kts Thursday afternoon at all terminals. /ZVS



MARINE
Northerly winds continue to increase across the coastal waters this afternoon and evening. Expect moderate to strong breezes for the southern waters, while gentle to moderate for the northern waters. These winds will continue to steadily increase through Thursday, with the strong breeze expanded into the northern outer waters. Gale force gusts are likely in the leeward of Cape Mendocino on Thursday afternoon, before increase in coverage across the southern outer waters Thursday evening. A Gale Warning is in effect for zone 475 from Thursday afternoon through late Friday night.
These strong winds are possible to expanded into the southern inner waters with the strengthening pressure gradient nearshore. At this point the coverage is not enough (<50%) to upgrade the Small Craft Advisory to Gale Force Warning. Next shift will continue to evaluate any changes on this. A Small Craft Advisory for winds is now in effect for zone 470 from Friday morning through late Friday night.
Winds may diminish slightly on Monday. The waves through this are generally expected to dominated by steep wind driven waves. /ZVS
