Area forecast discussion, Aug 15, 2:58 PM PDT, 3 hours 3 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
258 PM PDT Tue Aug 15 2023

.SYNOPSIS...Isolated, mostly dry thunderstorms continue to be
possible across portions of the interior this afternoon.
Additional thunderstorms are possible later in the week, but some
rain is expected with these. Above normal temperatures will
continue through Wednesday with temperatures slowly cooling later
in the week and into the weekend.

&&

.DISCUSSION...The upper level low off the coast of CA is
continuing to bring thunderstorms to the area this afternoon. For
now it looks like they will remain over the interior. These are
expected to only be isolated, however since they are high-based
they will likely be mostly dry. So have a red flag warning in
place for Trinity county. Thunderstorms elsewhere look to be more
isolated. The NAMNEST shows some ongoing showers continuing
overnight in the modeled reflectivity, but that is the outlier so
have left them out of the forecast for now. Hot temperatures
persist across the area with the with highs over 100 degrees in
much of the interior and the coast seeing highs in the upper 60s
to low 70s. Tonight will be another warm tonight with most areas
staying in the 60s and 70s.

Wednesday has the potential to see additional thunderstorms
across the interior, however confidence is low on this. Even the
NAM has less than 100 j/kg of CAPE on the Weaverville sounding in
the afternoon. The modeled reflectivity shows some showers or
possible thunderstorms north of Mendocino county so have
thunderstorms in the forecast still. Hot temperatures are expected
to persist again on Wednesday, although cloud cover could limit
this slightly. However with the warm overnight lows will continue
to elevated the heat risk so have left the excessive heat warning
and advisory in place.

Thursday and through the weekend the upper level low remains off
the central CA coast. This will continue to bring the potential
for showers and thunderstorms. Overall it looks like temperatures
will cool off and the storms are expected to become wetter. Early
next week some of the models are showing an upper level trough
dropping down out of the northwest. There are still a lot
differences in the ensembles and therefor uncertainty in the
pattern.

&&

.AVIATION...Weather conditions were interesting at CEC as a line
of mostly elevated Thunderstorms moved over Southern Oregon and
Del Norte County this morning with VCTS being frequently
reported...starting around 5AM. An actual thunderstorm was
reported and impacted CEC from 6-7 am with as much/little as 0.10
falling. CEC also reported unusually coastal stratus with the
convection; brief Cigs lowered into IFR. A little bit of elevated
smoke also moved from the north. Elsewhere...Thunderstorms/showers
moved into or built over interior mountains which could cause
concern for local general aviation. Aviation along the Mendocino
coast was impacted by a stratus surge moving northward; stratus-
fractus was seen along the southern Humboldt coast in the
afternoon. Various model data indicating some coastal marine Cigs
over the North Coast overnight which has been somewhat
acknowledged in the TAFS. /TA

&&

.MARINE...Relatively light winds are forecast today. Northerly
winds are expected to increase on Wednesday afternoon. NW swell
will gradually subside through tonight. Northerly winds are
forecast to increase over the N outer waters by Wednesday
afternoon, with these winds expanding across much of the outer
waters by Thursday night and Friday. Eventually, another Small
Craft Advisory will be needed for the outer waters, but that's
still 36 to 48 hours out. /SEC

&&

.FIRE WEATHER...Isolated thunderstorms are expected across the
interior areas again this afternoon. These are expected to be
fairly dry again. Strike numbers are uncertain, but it looked like
there will be enough to warrant a red flag warning. In addition
there will be some slightly stronger than afternoon winds. These
are expected to be 10 to 15 mph out of the northwest with gusts to
25 mph over favored areas and higher terrain. These are expected
to come to an end with once the temperatures start to cool this
evening. Wednesday there is the potential for thunderstorms along
with hot and dry conditions. MKK
