Synopsis Onshore flow will continue this weekend as a weak
weather system passes mostly to the north of the region. The
onshore flow will weaken early next week as ridging strengthens
for warmer temperatures and more sun. A weak front is expected
around the middle of next week for a chance of showers and
somewhat cooler temperatures.

Short term today through Monday Onshore flow continues this
morning with several layers of clouds covering most of western
washington. Upper ridging from earlier in the week has retrograded
offshore as a weak weather system passes mostly to our north and
east. Apart from stubborn cloud cover and slightly below normal
temperatures, weak troughing over the region won't generate much
weather for us. There may be a few pockets of morning drizzle near
the coast and some weak convergence north of seattle this
afternoon, but that's about it.

The flow aloft will back from northwesterly to westerly on Sunday
as another weather system passes mostly to our north. Much like
today, the sensible weather conditions will be virtually the same
with perhaps a little better chance of some late afternoon or
evening clearing. Upper ridging builds over the area on Monday in
response to a deepening trough offshore. The low level flow will
turn weakly offshore by later in the day. This will spell earlier
afternoon clearing and high temperatures closer to normal.

Long term Tuesday through Friday
Upper ridging continues to strengthen into Tuesday as an upper
trough lifts northeastward well offshore. Light offshore flow will
turn rather quickly onshore by later in the day, but not before
much of the interior sees what will probably be the warmest day
of the week with areas from about everett southward getting into
the 80s.

Whatever is left of a weak front will move onshore on Wednesday.

The 00z model runs have backed off with pops for the midweek front
compared to their 12z predecessors. Given the model inconsistencies,
not much was changed with the midweek forecast. For the rest of
the extended period, zonal flow aloft and typical summertime low
level onshore flow make climo temps and dry conditions a safe bet.

Aviation Weak low level onshore flow continuing through the
weekend. Northwesterly flow aloft becoming westerly on Sunday.

A couple of cloud layers over the area this morning. One a
scattered to broken layer around 2500 feet and the other a broken
to overcast layer in the 5000-6000 foot range. Lower layer will
become more consolidated and lower down to 1500 to 2000 feet by
15z. The lower layer will scatter out 18z-20z with the higher
layer remaining intact throughout the day. With the low level flow
remaining light onshore lower layer reforming in the 1000-2000
foot range early Sunday morning.

Ksea... Ceilings around 3000 feet lowering down to 1500-2000 feet
by 15z. This layer will scatter out around 19z with ceilings
around 5000 feet for most of the afternoon into the evening hours.

Ceilings lowering back down to near 1500 feet early Sunday
morning. Winds southwesterly 4 to 8 knots. Felton

Marine Weak onshore flow will continue through the
weekend. Surface flow becoming light Monday and Tuesday with a
weakening front on Wednesday. Small craft advisory winds possible
over the coastal waters as the front reaches the area.

start of the next rainy season; it will only be updated as needed
until then.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
