Area Forecast Discussion
National Weather Service Seattle WA
837 PM PDT Tue Jun 1 2021

.UPDATE...The current forecast remains on track and no changes are
planned for this evening.

Pullin

&&

.PREV DISCUSSION... /issued 300 PM PDT Tue Jun 1 2021/

SYNOPSIS...An upper ridge positioned across the area through
Wednesday with warm, sunny weather. Cooler marine air Thursday as
a weak front weakens over the coastal waters. A cool, showery
weather pattern for this weekend as a cold front arrives Friday
night into early Saturday with another system possible Sunday into
Monday.

SHORT TERM /TONIGHT THROUGH THURSDAY/...Skies over W WA remain
unblemished this afternoon as lowland temps are generally in the
upper 70s to low 80s both inland and along the coast.

The upper level ridge responsible for this will continue to meander
eastward into Wednesday as the ridge axis shifts over to E WA during
the overnight hours. The influence of this feature will remain into
Wednesday though as interior lowland highs will remain pretty
similar to what is expected today. The coast, however, will start to
get at taste of an onshore push that is expected to impact the
entire area on Thursday...but this only serves to lower highs there
by a few degrees into the mid to upper 60s.

Surface low pressure over E WA with high pressure over the Pacific
will see pressure gradients over W WA tighten Thursday, bringing a
significant onshore push to the area, which should knock temps back
into the mid 70s for most interior lowland locations with some
increase in morning stratus coverage before clearing up throughout
the day.

All in all, a fairly quiet short term forecast.  18

LONG TERM /FRIDAY THROUGH MONDAY/...An upper level shortwave will
entire into W WA early Friday but does not look to have any moisture
with it. Instead, looks like the next chance for rain will hold off
until at least Friday night as per both deterministic and ensemble
model data. Deterministic models do not show the front holding
together very convincingly...and that combined with the relatively
low QPF amounts from ensemble data suggests that this activity may
be more in line with showers than actual stratiform rain for most of
Saturday. Overnight Saturday may see a slight lull in activity
before the main upper low moves into W WA for Sunday. This system
seems to hold together at bit better potentially allowing rain to
linger into Monday...however there is a bit of uncertainty at this
point in the forecast. GFS brings the track of the low right into W
WA while the ECMWF keeps this low off the northern tip of Vancouver
Island, churning disorganized shortwaves around it and into W WA.
Ensembles seem to lean more toward the GFS solution but do indicate
some periodic lulls also. Opted to go with generally chance wording
during this time frame to indicate both the expected active pattern
as well as the degree of uncertainty.

One thing is clear though...the change in pattern will allow for
cooler temperatures. Highs Friday will still a little warmer than
usual with highs in the upper 60s to lower 70s in the interior,
around 60 on the coast. Saturday, Sunday and Monday will all be
below normal with temps in the lower to mid 60s inland, mid 50s to
around 60 along the coast.  18

AVIATION...Southwesterly flow aloft continues with light onshore
flow in the lower levels. Low level onshore flow will bring marine
stratus and resulting IFR to the immediate coast 09Z-18Z Wednesday
morning. Elsewhere, clear skies and VFR conditions will continue
through Wednesday.

KSEA...Clear skies. Northerly winds 8 to 12 knots becoming light
northeasterly late this evening.

MARINE...Strengthening onshore flow will persist into
Friday. Have issues a small craft advisory for the central and
southern inner coastal zones to reflect stronger northwesterlies
that have developed there this evening. Winds and seas will ease
around daybreak before picking up again in the afternoon and
evening, particularly in the Central and Eastern Strait of Juan de
Fuca. Strong onshore flow will produce possible gale force winds
Thursday evening in the Central and Eastern Strait with small craft
advisory winds in the adjacent waters. Small craft advisory winds
also possible over the coastal waters Thursday night as onshore flow
ramps up. A weak frontal system will reach area waters Friday night
and Saturday morning.

HYDROLOGY...The daily hydrology discussion has ended until the
start of the next rainy season; it will only be updated as needed
until then.
