Synopsis for northern california waters - Fresh southwesterly winds tonight will briefly decrease through the day on Thursday before a fast moving low pressure system brings a quick round of gusty southeasterlies for early Friday morning. Meanwhile, large building seas will reach around 13 to 17 feet on Thursday with chances for Thunderstorms across the coastal waters possible. Be on the lookout for robust north winds developing across the coastal waters over the weekend.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 258 PM PDT Wed Mar 27 2024
SYNOPSIS
Potential for thunderstorms with locally heavy rain, gusty winds and isolated hail showers will increase tonight and persist through Thursday as unstable conditions develop behind a cold front. A second storm system will approach from the southwest on Friday, bringing more showers and a threat for strong southeast winds for Mendocino and Lake counties. Drying and clearing trend is expected Sunday into early next week.
DISCUSSION
Cold front will exit the forecast area to the southeast this evening. A brief break in the widespread precip is expected late this afternoon into early evening before the leading edge of open cellular cumulus convection arrives mid to late this evening and overnight. HRRR and SREF calibrated guidance as well as convective allowing models continue to indicate increasing potential for thunderstorm mid to late this evening and overnight, mainly over the coastal waters and near the coast. Low topped storms with buoyant energy 500J/kg or less will likely persist into the day on Thu and perhaps into the Thu evening. Brief downpours of rain, gusty winds appears to be the primary hazard. Progressive storm motion will limit the threat for flash flooding. Isolated small hail mixed with rain is not completely out of the question either with stronger updrafts as freezing levels fall on Thu to about 3500 feet.
Snow levels fall late tonight into Thu down to about 3000-3500 feet. Latest QPF guidance from WPC indicates higher 6 hourly liquid equivalent rates from 0.20-0.40in, particularly over the coastal ranges of Del Norte and Humboldt. This is most likely due to the convective nature of the precipitation. Snow accumulations have increased to about 4 to 7 inches above 3000-3500 feet. A winter weather advisory for scattered advisory level accumulations has been hoisted for the western slopes of Del Norte and Humbodlt counties for late tonight into Thu above 3000-3500 ft. For Trinity, snow amounts are not as certain with less moisture available for over 4 inches for locations like Scott Mountain Pass at 5400 ft.
Another potentially stronger storm in terms of winds will move inside 130W southwest of Cape Mendocino and west of Pt Arena on Friday. GFS and ECMWF deterministic 925mb winds ramp up to 50kt just offshore. Meanwhile, the National Blend of Models (NBM) mean southeasterly wind gusts are now only around 20-30 mph with 90-95th percentile gusts around 40mph. There is still a great deal of variability and uncertainty with the track and location of the surface low and how strong winds will get on Friday for coastal Mendocino and interior ridges of Mendocino and Lake. Mendocino coast, particularly from about Pt Arena southward, may have gusts to 50 mph or more if 925mb winds mix down to mean sea level. This will need to be watched. Hopefully the next couple of runs of the HRRR and convective allowing models will shed more light on this.
Brunt of the precipitation with this next storm will most likely be directed into Mendocino, Lake and perhaps eastern Trinity.
Isolated thunderstorms with locally heavy rain will also be possible as a diffluent 500mb trough approaches on Friday. Lighter amounts of precip (if any) are expected in the wrap around for the northern portion of the forecast areas, namely the north coast north of Cape Mendocino.
Ensemble clusters were in general agreement with the 500mb cold core tracking SE along the California coast over the weekend.
There are very subtle variations on the track, how close it gets to the coast and where it will moves inland. There appears to be sufficient instability and wrap around moisture for continued precip chances (perhaps thunderstorms) for mostly Mendo. Lake and Trinity on Saturday. Ridge aloft folding over the 500mb cold core Sunday into Monday will most likely yield a drying/clearing trend from NW to SE. As skies clear, some frost will certainly be possible for the interior valleys. Positive tilted ridge aloft is forecast to hold into Tue, before clusters deviate significantly in response to a transient upstream trough. Daytime highs will warm up early next week (70s's to possibly lower 80's for the warmest interior valleys). Overnight low temps will remain chilly with some frost in the interior valleys under mostly clear skies, assuming no fog and low clouds form. DB
AVIATION
MVFR and periodic IFR conditions continue this afternoon as frontal showers move through the area. Gusty southerly winds will remain elevated at CEC and ACV as a strong surface low deepens and spins off the OR/WA coast. Scattered showers with isolated convection are possible overnight into early Thursday morning at coastal terminals, especially CEC. Otherwise, ceilings will lift overnight to produce mostly VFR conditions across all terminals, while UKI stays calm with mid level ceilings. JMM
MARINE
Southerly gusts and responsive wind waves will continue to develop in the northern waters behind a cold frontal passage. The tightening pressure gradient of the low will keep winds elevated in the outer waters as it continues to spin off the coast of Oregon. A secondary, large westerly swell with a nearshore fetch will fill into the area early Thursday and will generate steep 14-16 ft waves.
Combined seas are likely to exceed 18 feet in the northern outer waters through Thursday evening, but will remain just below haz seas criteria. Scattered convective showers are also possible overnight and early Thursday morning as post-frontal cooling generates instability. Elevated seas and hazardous conditions can be expected as the swell slowly decays through the end of the week. A shortwave is expected to drive a progressive surface low south along the CA coast on Friday, potentially producing a brief period of SE gale force gusts in the southern waters. There is still uncertainty regarding the proximity of the low to area waters and maximum gusts. JMM
