Fire Weather Watch 1, NWS Eureka, CA

AREA FORECAST DISCUSSION...CORRECTED
National Weather Service Eureka CA
340 PM PDT Mon Aug 7 2017

.SYNOPSIS...An upper level low will bring a threat of
thunderstorms to mainly the interior mountains through mid week.
Otherwise seasonable weather with slightly above average
temperatures are expected to prevail through the week.

&&

.DISCUSSION...An upper level low meandering about over the area
will continue to bring a threat for mainly diurnally driven
storms through at least mid week. The highest chances will be
during the afternoon and evening hours across the interior
mountains where instability, moisture and lift have been the
greatest. The primary threat with these storms will be hail and
locally heavy downpours. Be sure to keep a watchful eye on the sky
if venturing into the interior. Be ready to take cover if
menacing clouds approach.

Storms will also be possible out toward the coast and over
the coastal waters, however confidence is by no means high.
The easterly and southeasterly flow pattern Tuesday and Wednesday
does look favorable for storms propagating toward the coast. The
GFS continues to be hot and heavy with the convective
development across western portions of the forecast area.
The NAM and other higher resolution models on the other hand,
indicate storms confined to Trinity county and NE Mendocino
county with very little or no chance for storms over the coast.
The BUFKIT profiles reflect this as well. For now will not rule
out the possibility of an isolated boomer over coastal areas.
The best chances look to be mainly north of about Orick Tue
through Wed.

In the meantime, coastal areas will continue to experience the
typical marine stratus. The layer was much more extensive offshore
today with only partly sunny skies as of 3pm. Thus, expect a
quick return this evening with low cloud cover spreading back into
the north coast river valleys through the night. Given the
boundary layer RH's from the high resolution models and the BUFKIT
X-sections, expect diurnal stratus and perhaps fog to persist for
the next several days.

Temperatures will remain near or slightly above seasonal normals
for most of the week. The latest guidance suggest some warming
through the week, however not crazy hot like last week where
Trinity and interior Mendocino county saw max temperatures of
109-115F.

An upstream kicker will eventually push out the pesky upper low
toward the end of the week, resulting in drier southwesterly flow
aloft and less potential for diurnal storms over the interior.
The GFS and ECMWF do suggest another shortwave trough swinging
across the area over the weekend. This s/w trough may trigger some
shower activity. It is interesting to note as we move into the
forecast for days 6-10, the models suggest another upper trough
dropping southward from the NW. This trough may end up bringing
some precipitation to the northern portion of the forecast area if
the surface front does not dissipate. The detail remain very
elusive at the moment. Both models have the 500mb trough offshore
the Pacific Northwest as early as Monday. This is probably too
fast and for now will keep temperatures and weather conditions
near normal for mid August.

&&

.AVIATION...The stratus has pretty much eroded for the interior
portions of northwest California but along the immediate coast it
continues to hang around keeping IFR conditions in place. We're not
expecting to see much in the way of clearing for the immediate coast
thus IFR conditions are forecast to prevail throughout the day.
Persistence forecasting suggests that the stratus will surge inland
once again tonight and creep through the river valleys. Ukiah will
more than likely remain clear all night but model guidance has
suggested that a few low clouds might make their way into the area.
Confidence is not very high in this occurring, thus it has not been
put in for KUKI.

The other thing to note for today is the chance for thunderstorm
activity. This will primarily be limited to Trinity County but may
extend into eastern Del Norte and Humboldt counties and northeast
Mendocino County along the Yolla Bollys mountains.

&&

.MARINE...Light to moderate northerly winds will persist
through today, with locally gustier winds near and south of Cape
Mendocino and out past 10 nautical miles. Winds are forecast to
increase slightly on Tuesday and beyond, but are not expected to
exceed 25 kt. As a result, seas will increase slightly in both
height and steepness, particularly across the waters south of Cape
Mendocino, but are still expected to remain 8 feet or less through
at least Friday. Stronger north winds and steeper seas will be
possible over the weekend. BC/KR

&&

.FIRE WEATHER...A fair amount of cloud to ground lighting was
observed yesterday...mainly over NE Trinity with a handful of
strikes over the Yolla Bolly wilderness area. Given the position
of the upper low off the coast the axis of instability will shift
slightly westward today and remain in the same general area for
the next couple days. A subtle increase in instability combined
with more midlevel moisture should give way to more thunderstorm
activity today and an uptick in lightning strikes. Thus a Red Flag
Warning was issued to cover the anticipated area of focus...Zones
203...204...283 and the extreme northeast portion of 211.
Forecast models have been in good agreement on some rainfall
associated with these storms but given the amount of lightning
expected to fall outside of the rain cores and how dry the fuels
are a warning seems prudent. The other factor is the current
wildfires in proximity to the area of focus. Outflow winds
certainly could have an impact as well as potential IA drawing
resources from current fires. The low driving the current weather
pattern remains quasi stationary for the next couple days thus
additional RFW's will likely be necessary each afternoon and
evening through Wednesday. The threat appears to diminish toward
the end of the week as drier more stable SW flow aloft develops.
The models have been hinting at another short-wave impulse
swinging through the region over the weekend. This s/w may
spark up a few more storms over the mountains, however confidence
is low on the coverage and intensity of any more lightning
activity for the weekend. Interesting note, the GFS and ECMWF
have a 500mb trough digging south toward the NORCAL coast early to
mid next week. This flow pattern resembles a similar event back
in August (25th) of 2013 when several interior stations in
Trinity county reported 0.3 to 0.5 of an inch of rain.
