| Area Forecast Discussion National Weather Service Eureka CA 302pm PDT Wednesday September 11 2024 Synopsis An approaching upper trough will drive inland temperatures much cooler and bring chances for light rain and breezy conditions Wednesday. Additional chances for precipitation look probable in the extended forecast. Inland high temperatures will have remained well below average today with the introduction of a cold trough into the area. The associated frontal passage brought a quarter to half an inch of rain to Del Norte this morning, while Humboldt has seen anywhere from a few hundredths to a quarter inch so far. Light showers continue to propagate south and east through the rest of this afternoon, then taper off this evening. This system will drive gusty northwesterly to westerly winds through tonight, then winds significantly weaken Thursday morning. Temps warm up a bit Thurs and Fri, however this cool trend is forecast to continue through the week and into this weekend. Deterministic models have been well aligned for longwave troughing to persist aloft, with an additional shortwave approaching this weekend bringing precipitation chances. There is robust ensemble and cluster support for this active pattern to persist well into next week, with another trough possibly dropping into the region around midweek. Marine Light westerlies to northwesterlies persist this afternoon and overnight in the wake of a passing front. North winds will ramp up again to 20 to 25 kts Thursday afternoon through Friday before easing through the weekend. The sea state will be dominated by short period northerly waves and a small, northwest swell at about 6 to 8 ft at 10 seconds late Thursday. Fire Weather High temperatures remain well below normal this afternoon, will incoming moisture has significantly improved RH values across the area. A wetting rain has occurred most of Humboldt and Del Norte county, along with portions of Trinity county. Showers continue to spread south and east this afternoon, although most of Mendocino and Lake counties are likely to remain mostly dry. Gusty northwest winds will continue through this afternoon for eastern Trinity, southern Mendocino, and Lake Counties, especially in the higher elevations of Lake County, then weaken overnight tonight. RH values are forecast to trend down Thursday and Friday, then improve again this weekend as moisture associated with another trough approaches the area. This trough may bring another round of light precipitation to the area Sunday...however slight deviations in the track of this low could drastically change where and when any precipitation falls, as well as how any wind develops and evolves. However, there is good confidence in well below normal temperatures, moderate afternoon RH values and good recoveries. .EKA WATCHES/WARNINGS/ADVISORIES... CA... None.
