SYNOPSIS

Clear and dry conditions will remain through the week with a warming trend through Thursday. A weak and shallow marine layer will hang along shore. Temperatures will trend lower this weekend weekend.

KEY MESSAGES

- Northerly winds are much lighter, but will be breezy in the afternoons close to shore.

- Generally clear skies and dry conditions, even along shore, through the week.

- Conditions will warm through Thursday with highs in the interior peaking near 90.

EXTENDED DISCUSSION...(Saturday through Tuesday)

High pressure will weaken again this weekend, allow for slight cooling and more marine influence to push inland. Most models show a stronger and more consistent layer of marine stratus forming around Humboldt Bay and other protected areas, aided by gentle but persistent onshore flow. Most ensemble members continue to show a trough dipping across the Pacific Northwest early next week. The trough, however, will most likely be dry with only light drizzle on the coast and some weak showers inland. Even on the far North Coast, the chance of wetting rain is less than 10 percent. /JHW

AVIATION...(06Z TAFs)

Coastal stratus has developed around the Humboldt Bay and vicinity. As result, MVFR ceilings are reported at KACV. There is a 30-40% chances for IFR ceilings at ACV between 12Z-16Z. Meanwhile, mainly VFR conditions are expected to prevail at KCEC with the interior offshore flow; however, nearshore south winds may advect some low clouds into CEC overnight. There is a 30-40% chance for MVFR/IFR ceilings impacting CEC between 13Z-16Z. For the interior, including KUKI, prevailing VFR conditions through the forecast period. Expect breezy N-NW winds around 10-20 kts each afternoon with higher gusts for the terminals, diminishing after 21/02Z. /ZVS

MARINE

Gale-force gust northerly winds and very steep, hazardous seas are expected to continue through Friday across the outer waters. Meanwhile, moderate to strong gusty winds and steep seas are forecast ro continue for the inner waters. However, localized gale-force gusts are anticipated to redevelop again around Pt St George and in the lee of Cape Mendocino this afternoon.

Northelry winds are expected to diminish this weekend as the high pressure shifts eastward and the pressure gradient relaxes. Seas will also subside this weekend, and could be below 6 feet across the waters by Sunday. /ZVS
