Synopsis for northern california waters - Northerly gales in the northern outer waters will continue today through mid week. Large, short-period seas are forecast to build today through mid-week, with the highest wave heights in the northern outer waters Wednesday and Thursday. This pattern is forecast to persist for the latter portion of the week and perhaps over the weekend.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 315 AM PDT Tue May 14 2024

SYNOPSIS
A modest warming trend will continue through Wednesday.
Summer-like weather will persist through the week with hot afternoons in the interior and stratus along the coast. No precipitation is expected through the week.



DISCUSSION
A broad area of high pressure will continue to build across NW California through midweek, promoting calm and generally summer-like weather. This means sunny skies for the interior with hot inland valleys reaching the low 90s. At the same time, persistent onshore and northerly flow will continue to support gloomy stratus along the coast with clearing in the afternoon. No precipitation is expected. Though strong day time heating will help generate solid surface instability, the general lack of moisture makes any interior showers unlikely (less than 10% chance). Any showers that do appear would be weak and isolated to high terrain.
Though solidly above normal, inland high temperatures are still far from any kind of record. Low pressure along the Central California coast will keep the strongest high pressure offshore generally inhibiting any extreme warming.

Very similar, calm weather will continue though the week. Low pressure dipping over British Columbia late in the week will disrupt high pressure, bringing mildly cooling the interior back into the 80s by Friday. Perhaps the bigger impact is that any disrupting to high pressure will allow for better clearing along the coast (most likely by Wednesday night) and better penetration of marine moisture into the interior. Still, despite the upper level trough essentially no model shows any precipitation through the weekend. Long range predictions show calm, summer-like weather continuing to build for the foreseeable future. /JHW



AVIATION
Coastal stratus continues this morning, with ongoing IFR conditions for coastal terminals and possible brief LIFR ceilings around daybreak. Stratus should recede toward the coast this morning, but may be stubborn for much of the immediate coast once again today. More robust offshore winds are forecast to continue above Del Norte and develop above much of Humboldt, which may disrupt the marine layer and stratus at coastal sites north of Cape Mendocino this afternoon. There is potential for clouds to form around Humboldt Bay once again late tonight, however current guidance is split on this potential. Stratus is expected to be more stubborn for areas further to the south along the Mendo coast. KUKI should mostly remain VFR through the TAF period, although stratus is currently advecting northward up the Russian River Valley, and there is a chance for a brief period of LIFR early this morning should these reach the terminal.



MARINE
The surface high offshore is forecast to drift northward this morning, strengthening the pressure gradient off of Cape Blanco and weakening it near Cape Mendocino. This is expected to enhance northerlies downwind of Blanco in the Northern outers, particularly the NW corner of the zone. Meanwhile, winds are forecast to drop below GALE FORCE in the southern outers later this morning, with a southerly reversal developing in the southern inners. This MSLP pattern is forecast to persist through much of the upcoming week, with GALE FORCE WINDS persisting in the northern outers and generating large, steep, northerly waves propagating downstream into PZZ475 through the rest of this week.

A few small NW and S swells move through the waters over the next week, however seas remain primarily locally generated, dominated by short-period northerlies from the wind core in the northern outers. Short period seas look to hit their maximum late tonight...with hazardous seas propagating into the Northern Inners overnight. Seas are forecast to briefly relax early Wednesday, then steepen up again Wednesday night, so have opted to continue the Haz Seas Warning for the Northern Inners through into Thursday morning.
