AREA FORECAST DISCUSSION
National Weather Service Eureka CA
210 PM PDT Sun Aug 17 2025
.SYNOPSIS...A chance for showers and isolated thunderstorms over
eastern Trinity County today. A gradual drying and warming trend
will develop this week, with further warming late in the week.
&&
.DISCUSSION...After the frontal passage and light precipitation
observed Saturday, extensive stratus remains today. Early afternoon
satellite shows the low level clouds blanketing most of Humboldt
and Del Norte counties, with also a good portion of Mendocino
covered. This is due to a greatly deepened marine layer. There
was lower level shallow moisture contributing to patchy locally
dense fog, but that generally mixed out. Chances for fog are lower
tonight, with less coverage expected.
Soundings continue to show moisture at the 700 mb area with some
instability today, and forcing exists from passing shortwave
energy. Satellite imagery this early afternoon also shows some
billowing cumulus over the Yolla Bolly region and through eastern
Trinity County. These areas are where isolated afternoon showers
and a 10-20% chance for thunderstorms are forecast.
Moisture and instability mostly depart to start the work week
Monday. This will also mark the start of a gradual warming trend. A
shortwave perturbation will clip the northern region Wednesday, but
is expected to have little impacts other suppressing the greater
inevitable warmup. Beyond the passing of the shortwave, temperatures
will indeed further warm late in the week. Probability for isolated
warmer valleys to exceed 100 increases Thursday. Chances for
temperatures over 100 are highest Friday (75%) for the interior
valleys. Chances begin slowly dropping thereafter with a weak
signal from clusters of some troughing influence, but the heat may
linger longer through the weekend.
There are hints of some monsoonal moisture getting pulled in from
the SE next weekend. This would increase chances for
thunderstorms, but the quality of moisture and instability look
poor at this time. /JJW
&&
.AVIATION...Low clouds along the coast have been scattering and
lifting as a shortwave approaches. Currently, VFR conditions with
OVC layer around 3500-4000 feet, accompanied by some SCT layer
around 005 feet at ACV and CEC. Expect fluctuations in conditions
at the coastal terminals through 18/03Z, before IFR/LIFR
conditions redeveloped along the coast with low clouds and
visibility in FG/mist. Winds from W at around 5 kts, becoming very
light and variable after 3Z.
For inland areas: VFR conditions persist at UKI through the period.
Surface winds very light and variable, after 22Z becoming NW at
around 10kts with higher occasional gusts. There is the potential
for some isolated SHRA/TSRA across the eastern portion of Trinity
County this afternoon and early evening. /ZVS
