AREA FORECAST DISCUSSION . UPDATED National Weather Service Eureka CA 649 PM PDT Mon Aug 3 2020

SYNOPSIS. An upper level trough will bring a relative cooling trend to interior areas of northwest California through midweek, along with a deepening marine layer and more widespread and persistent coastal clouds. A stray thunderstorm might be found around the mountains of northeast Humboldt or northern Trinity County Tuesday or Wednesday afternoon.

UPDATE. Sending out a quick update to remove isolated thunderstorms that were erroneously added to the Tuesday morning forecast. /SEC

PREV DISCUSSION. Marine layer cloudiness has been a bit more reluctant to leave the lower Eel River Valley and the Humboldt Bay vicinity this afternoon, while other areas along the Del Norte County coast have had more luck, in part thanks to a weakening inversion and better mixing through the marine layer. Meanwhile the Mendocino coast started off sunnier thanks to stronger northerly diffluent flow coming around Cape Mendocino, but stratus has crept back in from Point Arena to Fort Bragg this afternoon. With an upper trough continuing to settle in through Thursday along the West Coast, a deepening marine layer will result in more extensive stratus along most of our coastline, aside from areas just downwind of Cape Mendocino. Additionally, the morning clouds should extend farther inland up the river valleys and some of the slopes of the coastal ranges, perhaps up to 2500 feet or so. These clouds will likely be quite persistent at the coast; while some limited afternoon sun cannot be ruled out, expect at least a couple of mostly cloudy days for Tuesday and Wednesday, if not into Thursday as well.

The initial upper trough may also bring just enough instability to allow for convective buildups over the mountains and possibly a thunderstorm late Tuesday. The best instability is currently indicated over the mountains in northeast Humboldt and northern/northeastern Trinity counties Tuesday and Wednesday afternoons, shifting farther east on Wednesday as compared to Tuesday. At this point the upper end potential may be only a single storm in the forecast area but still worth a slight chance mention.

Late in the week this upper feature moves east out of the area leaving split upper level flow over Northwest California. There appears to be a decent potential for dry northeasterly flow in the northern half of the forecast area with a substantial jump in warm air aloft. A 5-10 degree jump in high temperatures across the interior is likely from Friday into the weekend. Areas of overnight and morning fog and low clouds should linger at the coast, but the marine layer will be shallower with limited inland extent.

AVIATION . Afternoon satellite imagery shows stratus shifting mostly offshore along the North Coast, allowing for a few hours of sunny VFR conditions at KCEC and KACV. Expect ceilings at the coastal terminals to continue following the typical late summer diurnal trend, with stratus returning later this evening and producing IFR conditions through Tuesday morning followed by some clearing in the afternoon. Coastal profilers indicate marine layer depth decreasing with southward extent, therefore not expecting any stratus issues in the Russian River Valley including at KUKI during the TAF period. However, the presence of the deeper marine layer farther to the north may allow for a little more intrusion into the coastal river valleys of Humboldt and Del Norte on Tuesday. /CB

MARINE . Low end Small Craft Advisory conditions south of Cape Mendocino will spread to the northern outer waters tonight and persist through much of the week as northerly winds slowly trend upward. The advisory conditions will primarily be driven by winds over the first half of the week, with sea states dominated by modest short period seas in the absence of any notable swells. Both winds and seas will see a slight uptick during the middle of the week as Pacific high pressure builds closer to shore and tightens the gradient. Expecting these conditions to remain firmly in the Small Craft range and below Gale criteria for now. /CB

FIRE WEATHER . An upper level trough will bring a cooling trend through mid week. With the slight cooling there will also be a 5 to 15 percent increase in minimum afternoon RH values through Thursday across the interior, and a noticeable improvement in overnight recoveries, especially where the deepening marine layer reaches. The trough will also bring a small chance for a stray thunderstorm over the higher terrain of northeastern Humboldt and northern Trinity counties Tuesday and Wednesday afternoons. Potential remains very low and headlines in the fire weather forecast still don't seem warranted, though confidence is increasing for at least an isolated storm or two around northeast Trinity and adjacent Siskiyou County Wednesday afternoon. Warmer temperatures and drier conditions are expected to return for the end of the week and the weekend, with light offshore flow during the nights and mornings possible. /RPA

EKA WATCHES/WARNINGS/ADVISORIES. CA . None. NORTHWEST CALIFORNIA COASTAL WATERS . Small Craft Advisory until midnight Wednesday night for PZZ470. Small Craft Advisory until midnight Wednesday night for PZZ455-475.
