Area Forecast Discussion National Weather Service Eureka CA 425am PDT Monday May 12 2025 Synopsis Light to moderate showers along with gusty winds over the higher terrain. Showers will tapper off late this afternoon, with lingering showers through tonight. Followed by drier and warmer conditions by mid week. Northwest California is currently under the influence of a weak late season storm system involving cyclogenesis and an associated occluded front pushing onshore. This is bringing rain showers, mountain snow and gusty west-southwest winds. Radar doppler depicts light to moderate showers moving northeastward across the area, with periods of steady rain observed in Del Norte and Humboldt counties overnight. The low pressure will moves over the area today and keep driving southeastward through Tuesday. This will continue to support unsettled weather and cold temperatures through today/tonight. Isolated thunderstorms are possible (15-25% chance) this afternoon over the higher terrain north of Cape Mendocino, especially in Trinity County. Showers activity are anticipated to tapper off late this afternoon, with lingering showers through tonight. On Tuesday, a shortwave ridge will begin to builds in the wake of the trough filtering a slightly drier airmass. However, some isolated light showers are possible to developed inland Tuesday afternoon due to a lingering low level moisture and diurnal heating. A warming trend is expected to start on Tuesday, with inland highs warm up into the mid 60's to mid 70's. Enhancing onshore flow will remain the coastal areas in the mid to upper 50's. Areas of valley fog are expected to develop Tuesday night into Wednesday. All ensembles continue showing a high confidence for a weak ridging persisting across the area through late in the week. Expect warmer and drier weather conditions across Northwest California for the remainder of the work week. /ZVS Marine Northern waters are in Small Craft Advisory this morning, with the southern waters reaching SC.Y by this afternoon. Combined 6 to 9 foot seas will set in today and build to 10- 12 feet by late tonight into Tuesday early morning. Steep waves will keep small craft conditions going through at least Wednesday evening for southern waters. A short break from small craft conditions is forecast for northern waters by early Tuesday morning as steep waves return, with fresh to strong northerlies and steep seas begin to build again tonight into Tuesday, peaking in the afternoon. NBM has around a 30% chance of Gale Force gusts in the lee of Cape Mendocino Tuesday afternoon. /MH .EKA WATCHES/WARNINGS/ADVISORIES... CA... None. NORTHWEST CALIFORNIA COASTAL WATERS... Small Craft Advisory until 3am PDT Tuesday for PZZ450-470. Small Craft Advisory from 3pm this afternoon to 9pm PDT Wednesday for PZZ455.
