Area Forecast Discussion National Weather Service Eureka CA 253pm PDT Monday May 12 2025 Synopsis Rain showers continue to taper off this evening and overnight. A dry and warm pattern returns from Tuesday through the end of the week. A late season low pressure system continues to move through the area. A few showers still remain and will begin to taper off late this afternoon and overnight. There is an isolated chance(15%) for thunderstorms with a stronger shower in Trinity county this afternoon, but chances will diminish overnight. A very cold airmass aloft will support chilly overnight lows tonight, assuming skies clear tonight. Low temperatures range from the mid 30's to the low 40's across the area tonight. Many valleys may see low clouds or fog tonight as moisture remains available. Frost is unlikely, though not impossible in the coldest valleys like Hayfork, Covelo, and Lake Pillsbury. If temperatures do dip into the low to mid 30's, it will likely only be for a couple hours before sunrise, which should limit frost impacts. On Tuesday, a shortwave ridge will begin to build in the wake of the trough, bringing a slightly drier airmass. However, some isolated light showers are possible inland Tuesday afternoon due to lingering low level moisture and diurnal heating. Breezy northerly winds of 20- 30 mph are possible along the coast Tuesday afternoon as well. 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 to show high confidence for 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. JB/ZVS Marine Combined 6 to 9 foot seas will build to 10 to 12 feet across all zones overnight into early Tuesday morning as a low pressure system propagates northwesterly wave energy onshore. Conditions will diminish slightly in the northern waters before winds shift northerly and increase. Northerly wind waves are expected to maintain small craft conditions through Friday, mostly in the outer waters and in the nearshore waters downwind of Point St. George and Cape Mendocino. Daily diurnal surges will push these winds into portions of the inner waters each afternoon. .EKA WATCHES/WARNINGS/ADVISORIES... CA... None. NORTHWEST CALIFORNIA COASTAL WATERS... Small Craft Advisory until 3am PDT Tuesday for PZZ450. Small Craft Advisory until 9pm PDT Wednesday for PZZ455. Small Craft Advisory until 9pm PDT Wednesday for PZZ470- 475. |
