Synopsis Another upper level low will drop south today with
showers increasing over western washington throughout the day. While
chances for showers and isolated thunderstorms will linger in the
mountains through memorial day... Drier and warmer weather is
expected for the lowlands starting Sunday and into next week.

Short term today through Tuesday Current radar this early
morning remains pretty quiet while satellite shows low clouds in
place over the area but the bulk of moisture hanging out over the
coastal waters and moving to the south.

Models show that southerly flow is what will bring another upper
level low down along the coast and associated showers reaching
inland. Precip chances will gradually increase during the morning
hours with more widespread pops expected to kick in by late
morning early afternoon. Nothing breaks the stride of this system
though... As it will be down to the or ca border by tonight... Taking
precip activity with it. As this system plunges further south and
then moving inland by Sunday afternoon... Some wrap around moisture
may allow for mountain showers Sunday afternoon and evening. The
lowlands however should be able to remain dry and daytime highs will
rebound back into the 70s.

Upper level ridging off the coast will be the major weather feature
for memorial day keeping the majority of W wa dry and lowland temps
in the lower to mid 70s... Perfect for outdoor activities. Wrap
around moisture from the aforementioned low will still be an issue
for the cascades... And enough instability might be present for the
prospect for an afternoon early evening thunderstorm. Tuesday sees
the coastal ridge start to nudge its way inland... Allowing for warm
and dry conditions to continue. Smr

Long term Wednesday through Saturday This upper ridging will
remain in place over the area for the bulk of the extended with dry
conditions persisting. Low level onshore flow for much of this time
frame will keep afternoon high temperatures in check... Although
lowland interior locations are still looking at high temps in the
lower 70s. An upper level trough will start to nudge into the area
as early as Thursday night or as late as Saturday... Models are in
some disagreement as to when the pattern change will occur. But the
prospect for showers to return seems to be in the cards for next
weekend. Smr

Aviation Westerly flow aloft becoming southerly later this
morning then easterly this afternoon as an upper level low moves
south off the coast. Flow aloft becoming northeast overnight as
the low moves into northern california late tonight. In the lower
level onshore flow will becoming light tonight into Sunday.

Ceilings over the interior in the 3500-4500 foot range lowering to
1000 to 2000 feet by late morning and remaining in that range
through the afternoon. Improving trend this evening with low cloud
decks dissipating leaving just mid and high level clouds.

Ksea... Ceilings near 3500 feet lower to around 2500 feet by 15z
then down to around 1500 feet by 19z. Ceilings improving tonight
to AOA 10000 feet by Sunday morning. Southerly winds 4 to 8 knots
becoming northerly 00z-03z Sunday. Felton

Marine Onshore flow today will weaken becoming light
tonight into Sunday. Gale force winds over the outer coastal
waters and small craft advisory winds over the inner coastal
waters will ease to 20 knots or less tonight. Westerly swell will
subside below 10 feet tonight.

Onshore flow will increase again on Monday and continue through
Wednesday with high pressure centered well offshore. Small craft
advisory westerlies are possible in the central and eastern strait
of juan de fuca each evening. Felton

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.
