Synopsis A strong upper level ridge with low level offshore
flow will result in one more sunny and warm day today with record
high temperatures likely. Onshore flow will bring marine air inland
tonight and Thursday bringing in clouds, moisture and cooler
temperatures. Light rain will spread northeast across the area
Friday marking the start of an active weather pattern through the
weekend. Temperatures for the remainder of the week will be near
normal.

Short term today through Friday A wide range of temperatures
across W wa this morning with lower 40s down in the south sound area
such at tacoma and olympia while sea-tac has already gone into the
60s with a current ob of 61 degrees. Skies over the area are
generally clear and thus providing favorable conditions for further
warming.

Given the type of winter experienced over the area... Feels almost
karmic that the start of astronomical spring... The vernal
equinox... Would be met with almost summer-like temperatures as today
looks to once again see widespread 70s for afternoon highs in the
lowlands. This looks like the end of the road for these sorts of
temperatures... For now at least. A shift to onshore flow this
afternoon might be too late to make a significant impact in high
temps this afternoon... But incoming stratus tonight as well as an
upper level low wrapping moisture up into the area tomorrow morning
will bring temps down closer to seasonal expectations... Although
still a few degrees above that with most lowland locations seeing
highs right around 60 Thursday. Although the aforementioned low does
wrap some moisture over the area... Precip chances look lackluster at
best. Inherited pops are mostly of a silent single digit
variety... Although some locations might creep right to that 10 pct
slight chance threshold. Best chance for rain looks to come with a
front that models prog to reach the coast right around noon on
Friday... Although this front has a hard time holding together once
it enters into W wa. There does look to be sufficient moisture to
maintain the inherited chance pops however temps should remain
pretty stable with highs still expected to be in the upper 50s to
right around 60. This front looks to be the kick off to an active
pattern that will extend into the long term.

Not really seeing anything that screams morning update... So will
allow inherited forecast to ride until 12z data comes in and even
then... Only expecting minor tweaks to come with fresh data. Smr

Long term Saturday through Tuesday From previous discussion... A
weak upper level trough behind Friday night's front will give
showers to the area on Saturday. The showers will gradually come to
an end Saturday night as high pressure aloft builds into the area
and surface high pressure builds northward into british columbia.

Sunday now looks dry with low level NE to E flow increasing ahead of
the next negatively tilted frontal system that will be approaching
from the southwest. Temperatures aloft won't be as warm as they have
been the past few days, so expect high temperatures on Sunday to
stay in the mid 50s to lower 60s. Rainfall associated with the next
frontal system will move into the area on Monday. Albrecht

Aviation Southeasterly flow will continue aloft with low level
offshore flow continuing into today. The air mass will remain dry
and stable. Easterly winds will increase across portions of the
southern sound near 18z. Winds generally east-northeasterly from 5
to 15 knots. Gusts up to 25 knots possible for ksea and khqm. Winds
will turn more onshore tonight with increasing cloud cover late
ahead of a weak frontal system.

Ksea...VFR conditions with northeasterly winds becoming easterly 10-
15 knots by midday. Winds expected to pick up again near 18z, with
gusts up to 25 knots possible at times. Increasing cloud cover
tonight with onshore winds generally following 09z. Jd

Marine Offshore flow will persist through this evening. Breezy
winds near the gaps of the coastal terrain - strongest easterly
winds will be along the central strait of juan de fuca through this
morning. Light onshore flow will develop on Thursday ahead of a
weakening front spreading into the region on Friday. Westerly swell
10 to 11 feet will begin to affect the coastal waters Friday night
rising to 12 feet at 16 seconds Saturday.

Hydrology River flooding is unlikely over the next seven days.

Sew watches warnings advisories
Wa... None.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
