Area Forecast Discussion
National Weather Service Eureka CA
359 PM PDT SAT JUN 11 2016

.SYNOPSIS...Inland temperatures will increase several degrees
throughout the interior tomorrow as a subtle ridge moves
overhead. Temperatures will fall once again next week as another
low pressure system approaches the region.

&&

.DISCUSSION...While temperatures will be on the rise to close out
the weekend, mild and unsettled weather is expected to return
Monday through the end of the week as an unseasonably deep low
pressure system approaches the NorCal coast. Before this occurs
though, a building low amplitude upper ridge will result in above
normal temperatures tomorrow afternoon across the region, with
afternoon temperatures likely to reach the upper 80s to low 90s
throughout interior valleys. Breezy northeasterly offshore winds
will also return to the region overnight tonight, affecting mostly
the exposed upper slopes of the interior mountains. This will have
fire weather implications for those regions affected, and more
details can be found in the fire weather discussion below.

Attention will then turn to an approaching low pressure system
from the Northwest, which is currently located in the Gulf of
Alaska. By Monday, height falls and a weak cold front associated
with this low will move onto the coast, resulting in cooler
afternoon temperatures and increasing cloud cover. Periodic
episodes of drizzle and a few light showers will be possible along
the Redwood Coast late Monday through Tuesday as well, but any
precipitation that falls during this period will be very light and
mostly inconsequential. By Wednesday, the center of the upper low
will dig southwards into our adjacent offshore waters, and
shortwaves pinwheeling around the larger parent low will begin to
move through the region. As a result, multiple periods of showers
will be possible from late Tuesday through the end of the work
week. Coverage will likely be very limited and restricted to the
eastern half of the Klamath Mountains through Wednesday night
given the generally unfavorable southwest flow regime, and
marginal forecast instability/lapse rates will preclude the
mention of thunderstorms for the time being. Better chances for
more widespread showers and accumulating rainfall appear to exist
on Thursday/Friday, as a vigorous shortwave and associated
unseasonably strong surface low is set to move onto the coast.
While this feature would be somewhat anomalous for this time of
year, and there remains some skepticism as to its validity, it has
been a relatively consistent feature in recent model forecasts. At
this point, it seems more and more likely that at least portions
of the area will see some late season accumulating rainfall with
this feature, and precipitation probabilities have been increased
accordingly. /BRC

&&

.AVIATION...VFR conditions and moderate, gusty winds will
continue at KCEC and KACV through this evening. VFR conditions and
light winds will prevail at KCEC and KACV overnight. VFR
conditions and moderate, gusty winds will occur at KCEC and KACV
on Sunday. VFR conditions and light winds to calm conditions will
continue at KUKI through Sunday.

&&

.MARINE...A strengthening offshore high pressure system combined
with an inland low pressure trough has increased the winds across
the region. Elevated winds and short period seas will persist
across the waters this weekend. The winds and short period seas
will gradually diminish Sunday night and Monday as a cold front
approaches the area weakening the pressure gradient. Northerly
winds will gradually diminish Tuesday through Thursday. Short
period seas will peak tonight and Sunday. The seas will gradually
subside Monday through Thursday. Gale warnings will be in effect
across the near shore waters through early Sunday morning. Gale
warnings will continue across the outer waters through Sunday
evening.

&&

.FIRE WEATHER...A strengthening thermal trough will result in the
return of breezy northeasterly offshore winds tonight throughout our
interior mountains. Much like last night, the locations most
likely to be affected by these winds will be the upper slopes,
where gusts to 20 or 30 mph can be expected. RH values in the
upper slopes will likely begin to recover this evening as
temperatures cool; however, as offshore winds increase overnight
and early tomorrow morning RH values will likely fall fairly
rapidly and remain low through the early morning. As is often the
case with nocturnal offshore wind events, this will have a high
degree of spatial and temporal variability throughout the region,
with rapid swings in humidity and winds possible depending on the
exact location. Meanwhile, most lower elevation valleys and
drainages should decouple and experience mostly light winds and
good humidity recoveries.

During the day tomorrow, a building upper level ridge will cause
temperatures to increase into the upper 80s and low 90s in the
valleys, with slightly cooler temperatures at higher elevations.
Moisture will remain low through the day, resulting in afternoon
RH values generally in the teens. Prevailing winds will
progressively shift from the northeast to northwest as the sea
breeze moves inland, with generally modest wind speeds expected.

While fuels continue to dry out as we head into the summer,
particularly fine fuels at lower elevations, their receptiveness
to large fire growth remains questionable. As such, a Red Flag
Warning does not appear to be necessary at this time. /BRC
