AREA FORECAST DISCUSSION National Weather Service Eureka CA 453 AM PST Wed Feb 19 2025

SYNOPSIS
A quick hitting rain system will continue to impact the area through this afternoon. The strongest rain will be focused along the Humboldt and Del Norte coast. Conditions will quickly calm and begin to dry by tonight.

DISCUSSION
A frontal system moving onshore overnight, and will continue to push eastward across the forecast area this morning.
Strong southerly winds have developed along the North Coast overnight. These winds are expected to peak briefly early this morning, with gusts from 40 to 50 mph over the coast headlands and exposed ridges in Del Norte and Humboldt counties...locally higher over the more prominent ridges. As of 3 AM PST, radar reflectivity a band of light to moderate rainfall along the coast.
Isolated to numerous showers are expected in the wake of the front after sunrise. Shallow instability will allow convective showers capable of produce heavy rain rates up to 0.40 in/hr this morning. Rain will be strongly focused along the Northern half of the area, with 0.6 to 1.5 inches most likely across Del Norte County and 0.2 to 0.6 inches in Humboldt. Locations further inland and south will most likely see less than 0.25 inches. The heaviest precipitations is expected to occur in a 6 hour period right after 5 AM this morning. Snow levels remained over 5000 feet this morning. Scott Mountain Pass on Highway 3 will see some snow, up to 2 inches. The fast moving shortwave trough is expected to exit eastward late this afternoon, with lingering light showers through this evening, mainly across the northern forecast area.

High pressure is expected to builds in downstream of the upper level trough tonight through Thursday. This will promote clearing skies and dry conditions across the area, with surface offshore flow developing. Cold air advection will allow cold temperatures tonight into Thursday. Low temperatures are forecast to be generally in the mid 30's for the coastal and interior valleys, while mid to upper 20's for the valleys in Trinity County.
Although, for areas where skies clear out quickly, areas of valley fog are expected to develop tonight into Thursday. /ZVS

EXTENDED DISCUSSION
Ridging late the the week will generally bring warmer and drier conditions with possibly even a ragged and shallow marine layer along the coast. A shortwave in the ridge will most likely generate some moderate rain this weekend, but timing is uncertain with rain possible anywhere from Saturday through next Monday. Rain would most likely be shallow and focused only along the coast. /JHW

AVIATION
A fast moving front has arrived this morning.
MVFR or IFR conditions are expected as the front passes. Gusty winds and the LLWS threat at the coastal terminals persist as the front passes. Both the gusty winds and LLWS will diminish by sunrise. Post- frontal showers will bring varying conditions at all the terminals today, with mainly IFR to MVFR conditions expected in the morning, and MVFR to VFR conditions in the afternoon. Showers diminish late this afternoon and evening. JB



MARINE
A system is moving across the area this morning, bringing near-Gale to Gale Force southerly gusts north of Cape Mendocino.
This is a quick moving system, and winds will sharply decline and turn west-northwesterly after the frontal passage. The associated steep wind waves will quickly decay today, but seas will remain elevated as a large mid-period westerly swell of 10-12 ft fills in.
Northerly winds increase tonight into Thursday, particularly south of Cape Mendocino. 20-30 kt gusts are possible Thursday afternoon south of the Cape, with the strongest winds in the lee of the Cape.
North of the Cape, winds will be slightly weaker (15-20kts), with seas characterized mostly by decaying westerly swells. Winds ease Friday, but another long-period westerly swell of 10-12 ft is forecast to fill in, elevating seas once again. Another system is expected this weekend, bringing gusty southerly winds and steep seas. JB



BEACH HAZARDS
A westerly swell of around 8-10 ft at 16 seconds is forecast to build into the waters Friday. With light winds and mild weather expected Friday, beachgoers should be cautious as this swell presents a moderate sneaker wave threat. Be cautious visiting steep beaches and jetties and remember to never turn your back on the ocean. JB
