AREA FORECAST DISCUSSION National Weather Service Eureka CA 524 AM PDT Sun Jul 25 2021

SYNOPSIS. SYNOPSIS . Interior valley temperatures will top out around 100 degrees today, while periods of sunshine and mild afternoon conditions occur near the coast. Otherwise, showers and isolated thunderstorms will be possible starting Monday, with a greater threat of storms on Tuesday.

DISCUSSION. Current IR satellite imagery shows some high clouds streaming in from the SW, marking the beginning of the approach of anomalous southerly surge of monsoonal moisture. Smoke aloft, and some surface haze may make it closer to the coast today. Thicker smoke blankets E Trinity County, where an Air Quality Advisory is currently in effect. The smoke is modeled to push eastward again this afternoon in the diurnal wind cycle.

A moderate heat risk will continue today with some valley temperatures exceeding 100 degrees. Temperatures will moderate slightly early next week as the upper high pressure ridge that has nosed into the area from the SE weakens. Temperatures will warm again from mid to late week.

Mid to upper level monsoonal moisture will continue to increase from the S tonight and through Tuesday. Some model guidance is indicating some lobes of vorticity on the NW periphery of the aforementioned upper ridge advecting across the area during Monday afternoon and evening. Some modest elevated CAPE will be present across portions of the area during the same time period. This still may support an isolated thunderstorm or two during that time period. However, high resolution model guidance also seems to suggest increased overall cloudiness during this time period. Moreover, some lingering smoke may also limit destabilization due to daytime heating. However, a monsoonal surge of this magnitude to NRN CA is a rare event, with complexities in mesoscale features which models may not handle well. The density gradient along the leading edge of the moisture surge, coupled with interactions with higher terrain will be one such example. The sounding profiles for Monday suggest any stray storm that can form will be on the dry side, with better forcing and deeper moisture through the column and better storm coverage expected Tuesday. High PWAT values fill in Tuesday through through Tuesday night, perhaps reaching upwards of 1.7 in, contributing to a more buoyant air mass. Another moisture surge may push through later Wednesday.

AVIATION. Widespread marine stratus and fog overnight has maintained coverage over the coastal plain as expected leading to IFR conditions at both KACV and KCEC. The profiler at KACV indicates the layer to be 1000' to 1500'. Given model guidance and the depth expect the stratus to burn off by early afternoon at KCEC and a bit later into the afternoon at KACV. VFR conditions are expected to continue at KUKI. Winds are expected to be generally light. /MKN

MARINE. Northerly winds are expected to continue through the period, with occasional gusts to gale force across portions of the northern outer waters. The strongest winds are expected to shift a bit farther offshore across the S waters as we head into early week. Again, the gale force gusts are expected to cover less than 50% of either zone through the period. Hazardous sea conditions are expected to continue through Sunday night. A mid-period NW swell and a long period SSW swell is expected to return today, but both of these swell trains are expected to be fairly small, and the forecast will continue to be dominated by short period, locally generated waves. /MKN

FIRE WEATHER. Isolated showers and even a stray thunderstorm cannot be ruled out Monday afternoon or evening, mainly from the Trinity Alps, northeast Humboldt, eastern Del Norte and western Siskiyou County as elevated monsoonal moisture streams northward across our area. Meanwhile, the chance for isolated to scattered thunderstorms will exist on Tuesday, particularly from the mountains of Mendocino National Forest across Trinity County and western Siskiyou County, as somewhat better instability and forcing for triggering convection is anticipated.

EKA WATCHES/WARNINGS/ADVISORIES. CA . None. NORTHWEST CALIFORNIA COASTAL WATERS . Hazardous Seas Warning until 3 AM PDT Monday for PZZ470.

Small Craft Advisory until 3 PM PDT Monday for PZZ475.
