area forecast discussion
national weather service seattle wa
842 pm pdt Thu aug 22 2019

Synopsis High pressure across western washington will be
somewhat suppressed by Friday as a low pressure system pushes
across central bc through Saturday. With a few showers around, the
weekend will be cloudier but with temperatures continuing near
normal. Next week a stronger ridge of high pressure will build
north into the region through mid week so temperatures will climb
above normal with more Sun and drier weather.

Short term tonight through Sunday The weak upper level ridge
over the region will flatten overnight as a weak system moves into
southern b.C. Dry conditions are expected across most of western
wa with mainly mid and high clouds aloft. The current forecast
looks on track. 33
previous discussion... A trough of low pressure will track well
north of the area on Friday, bringing the increase in cloudiness.

A few showers will skirt the far northern tier Friday but most
everywhere will remain dry with temperatures close to normal.

Heights will fall overnight Friday into early Saturday and the
main system slides east across central bc. A few showers may be
expected on Saturday but limited mostly to the coast, olympic
peninsula, and north cascades. Otherwise just cloudy skies and
temperatures cooling slightly below normal for Saturday. On Sunday
a strong ridge of mid level high pressure will attempt to push
northward as the trough over bc exits east. This will bring a slow
increase in 500mb heights late Sunday, but temperatures will not
respond and should remain near normal. Sunday will be mainly a dry
day with mostly to partly cloudy skies.

Long term Monday through Thursday Previous discussion... For
next week the continued theme will be for the attempted northward
building of the strong 500 mb ridge to our south. Its full
northward push will be somewhat thwarted by another trough pushing
through central bc in the mon-tue timeframe. What does appear a
good bet is a warming trend from Monday on through mid- week, as
500mb heights should peak in the 583-587dm range by late Tuesday.

The surface translation will be for temperatures well into the low
and mid 80s for most spots by Tuesday and Wednesday. The surface
pattern suggests a thermal trough and thus some degree of low
level offshore flow will be present to help boost temps as well.

Heights look to begin falling by Thursday as surface high pressure
also builds in, ending the offshore component of the flow. This
will bring cooling temps by Thursday. Next week looks to be dry
and warm to possibly very warm at times, and possibly into the
upper 80s south of seattle on Wednesday.

Aviation Weak high pressure over the region will flatten
overnight and Friday as a weak system moves into southern b.C. The
flow aloft is westerly, with onshore flow near the surface. There
is a patch of stratus on the lee side of the olympics, around
3000-4000 ft, which should dissipate this evening. Patchy low
clouds may develop along the coast overnight for MVFR ceilings,
otherwise expect mainlyVFR conditions in the interior. 33
ksea...VFR conditions expected with N wind around 5 kt. 33

Marine Onshore flow will continue across western wa tonight
with westerly winds rising through the strait of juan de fuca - a
small craft advisory remains in effect. A weak system will track
into southern b.C. On Friday. High pressure over the NE pacific
will maintain onshore flow through this weekend. The flow will
turn more northerly and offshore early next week as a thermal
trough forms along the coast. 33

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

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisory until 3 am pdt Friday for central u.S.
