Synopsis Dry northerly flow aloft developing tonight and
continuing into Thursday. The next frontal system will arrive from
the northwest on Friday. Another cool upper level trough will
follow the front for the weekend into the early part of next week.

Low snow levels will continue through the period.

Short term tonight through Saturday Showers will continue to
decrease this evening as an upper level trough exits. Dry
northerly flow will allow some clearing with a cold night ahead -
lows into the mid 20s to lower 30s. May see freezing fog in the
south sound. Thursday will be dry with highs in the lower to mid
40s.

Moisture will spread into the area on Friday as our next front
arrives. Initially, we may see reports of rain snow mix as snow
levels will remain low through the morning. We should see mainly
rain in the lowlands during the afternoon as onshore flow
increases. The best shot at seeing snow will be areas near the
cascades, over 1,000 feet. In fact, we may need winter weather
headlines for the cascades as the passes will likely see 4-8".

Saturday will be a cool and showery day as an upper level low drops
down from b.C. Snow levels are still low, around 1,000 feet, with
a rain snow mix expected on the higher hilltops. The afternoon
forecast high temperature is only 40 degrees which is 10 degrees
below normal. 33

Long term Sunday through Wednesday A few showers will linger
into Sunday as the cool upper level low slowly exits. Shower
activity is mainly isolated to scattered, but as mentioned above,
we may see a rain snow mix at higher elevations. The air mass
starts to dry out again as we move toward Monday, while offshore
flow strengthens. But this sets us up for the next round of
lowlands snow, possibly Tuesday or Tuesday night. By then we have
moisture moving up from the south with a warm front while the low
level air mass will remain cool enough for snow. The models are
not exactly aligned so overall confidence remains low. The ecmwf
is drier compared to the GFS at this point. We'll see how this
pans out over future solutions. Looking further ahead, a warmer
system may bring higher snow levels and warmer conditions toward
the middle of the week - back to rain in the lowlands. 33

Aviation There are still some clouds and scattered light showers
over western washington this afternoon. Northerly flow and drier air
will arrive tonight for clearing skies and it should be sunny on
Thursday. There will probably be a few patches of low clouds or fog
Thursday morning, but they will not persist too long.

Ksea... Skies will clear this evening. A north breeze will persist
into Thursday.

Marine Small craft advisories are up for the coastal waters for
the swell. Breezy northeast winds are expected to develop tonight in
the northern waters as high pressure builds over british columbia. A
cold front will reach western washington on Friday.

Hydrology River flooding is not expected for the next 7 days.

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.
