Synopsis for northern california waters - Westerly winds at a light to gentle breeze in the northern waters will last through the weekend with a persistent nw swell at 9 seconds, 6 - 7 feet in height. A longer period W swell at 14 to 15 seconds will arrive Saturday with waves 2 - 3 feet high. Otherwise, a moderate to fresh breeze in the southern waters and steep to square waves will bring conditions in and out of small craft advisory criteria, tonight through Saturday. Larger combined seas are expected early next week around 10 feet in height with steep dimensions.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 454 AM PDT Fri Apr 26 2024
SYNOPSIS
Rain showers will continue across the area today.
Tonight chilly temperatures are expected with some of colder valleys seeing frost. Showers are possible again Saturday afternoon. Generally dry conditions and below normal temperatures are expected Sunday and into next week.
DISCUSSION
The upper level trough over the west coast continues to bring showers to the area this morning. Rainfall amounts have been the highest in the mountains of Humboldt and Del NOrte counties with around a half inch reported from 10pm to 4am.
Farther south and east rainfall amounts have ranged from a trace to a tenth of an inch overnight. These showers are expected to continue through the afternoon, mainly in Humboldt and Del Norte counties. NBM thunder probabilities were showing a 10 to 15 percent chance of thunder this afternoon across the interior, but instability looks shallow so kept it out of the forecast. This afternoon northwesterly winds will start to pick up across the area, but mainly in Mendocino and Lake counties. Gusts of 25 to 35 mph are likely over the higher terrain and wind prone in these areas.
Tonight will be chilly with the cool airmass in place over the area. H850 mb temperatures will be just below freezing. This will likely allow frost to form in the valleys that clear out tonight.
Confidence is low on exactly where this will occur, but Trinity, Mendocino, and Lake counties have seen the least rain so will be the most likely to remain clear tonight. Freezing temperatures are possible, but for now have just issued a frost advisory for portions of these counties. This may need to be adjusted based on cloud cover and dewpoint trends this afternoon and evening.
As the upper level trough moves out of the area zonal flow sets up. The newer model runs are now showing a shortwave moving through this zonal flow Saturday afternoon bringing some light rain to Humboldt and Del Norte counties once again. Amounts look to be less than tenth of inch. These clouds will likely linger through the night and keep temperatures from dropping as low overnight.
Sunday and Monday zonal flow is expected to persist in NW California. This is expected to keep temperatures below normal and some clouds in the coastal and near coastal areas. Frost is possible each night, but will be highly dependent on cloud cover.
It is certainly possible another shortwave will move through this flow and bring some light rain. Tuesday and Wednesday it looks like the temperatures will start to warm back towards normal with the NBM showing temperatures back in the 70s. However, one or two of the four ensemble clusters are showing the upper level trough sticking around and bringing continued cool temperatures. MKK
AVIATION
Coastal Terminals: Light winds out of the west with light rain showers continuing through the morning at KCEC. Ceilings below 500 feet as stratiform rain and low level saturation linger into the late afternoon. Short periods of lifting could bring sub 1000 foot cloud base but most of the improved flight categories will come this evening after 5pm. Similar IFR/LIFR conditions are expected at KACV. Drier flow can be seen in the water vapor image as well as shallower saturation in the model soundings. Periodic showers will continue at KACV into the early evening as flight conditions will improve to MVFR, though improvements will be inconsistent.
UKI: Winds are from a more northerly direction and will produce gusts later this morning which will last into the afternoon.
Ceilings below 2500 feet will eventually lift by the late afternoon to around 5000 feet. Model soundings show saturation near the tarmac, if skies clear as expected this evening there could be fog or mist as a hindrance to visibility.
