What forecasters said that day
The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Eureka, CA wrote its last area forecast discussion before this small craft advisory went out at Apr 1, 2:19 PM PDT, 2 hours 26 minutes earlier.
Area forecast discussion, Apr 1, 2:19 PM PDT, 2 hours 26 minutes before
AREA FORECAST DISCUSSION National Weather Service Eureka CA 219 PM PDT Sun Apr 1 2018 .SYNOPSIS...An upper ridge will result in mostly dry weather Monday through Wednesday. A Pacific storm system will bring the potential for significant rainfall Thursday through Saturday. && .DISCUSSION...The tail end of an upper trough moving across the Pacific Northwest this afternoon will bring a chance for light rain to mostly Del Norte and northern Humboldt counties tonight. Upstream surface observations in Oregon have been reporting light rain associated with this weak shortwave. High resolution models appeared to have the best handle on the low level moisture and shallow precip. Overall, expect very light rain/drizzle amounts, with less than a tenth by daybreak Monday. High pressure will rebuild behind the shortwave on Monday and expect spotty light precip to quickly wind down as subsidence increases through the day. The dry conditions will last through Tuesday and probably on Wednesday as a broad flat ridge aloft develops over the area. A moist westerly flow pattern will start to emerge around Thursday resulting in the potential for significant rainfall Friday through Saturday. A positive tilted trough will become positioned from the Gulf of Alaska southwest to the subtropics. This will allow rich moisture to spread northeastward toward California, accompanied by robust midlevel warming and large scale ascent. The period of heaviest rainfall looks to be Friday night into Saturday morning with frontal passage, however the front could speed up or slow down. The threat for hydrological impacts will need to be monitored as we head into mid week. Cooling aloft and lowering snow levels will follow next weekend after frontal passage, though there is still uncertainty on how fast this transition will occur or if it will occur in multiple stages. An upper level trough will slowly transition across the Pac NW Saturday through Sunday, with periodic perturbations in NW cyclonic flow aloft generating bouts of precip and showers for NW California through the weekend. The snow levels appear to remain relatively high, above 4500 to 5500 feet. This will need to be monitored for possible impacts as the weekend grows closer and snow levels and amounts become more certain. && .AVIATION...A weak frontal system will pass over the region tonight which may bring isolated showers to areas north of Cape Mendocino. The best chance for rain will be in Del Norte County and then dwindle as you move south. There maybe some patchy fog in the river valleys, but overall VFR to MVFR conditions are expected to prevail. && .MARINE...Fresh northerly breezes continue to drive steep seas throughout the waters with buoys reporting seas generally between 3 to 6 feet with a period of 6 seconds. The worst conditions continue to be located near and south of Cape Mendocino, particularly near the Lost Coast. This will continue to be the case for the rest of this afternoon. Winds will gradually weaken this evening and overnight as a cold front approaches. This reprieve will be brief, and 20 to 30kt north winds will return quickly early Monday morning and continue through Monday night as the cold front exits the region. This will cause seas to build a bit throughout the day Monday and Monday night, likely to around 8 or 9 feet at 7 seconds. Winds will decrease markedly Tuesday and Wednesday, allowing seas to settle below 5 feet. These two days will be the calmest of the week by far, as a series of cold fronts will bring the return of strong southerly winds Thursday through the end of the week. While the timing and strength of these winds remains a bit uncertain at this stage, at the very least steep seas will once again build throughout the waters, likely rising above 10 feet by the end of the week. /BRC/KR && .EKA WATCHES/WARNINGS/ADVISORIES...
