Synopsis Strong westerly flow aloft will prevail today. Weak
high pressure aloft will move over the region tonight. Expect a
pacific storm to impact the region Tuesday through Wednesday for
gusty winds and locally heavy precipitation.

Short term
There were scattered showers over the area at this time. The
showers were more numerous over the mountains. Expect small hail
to accompany the heavier showers on the lowlands today. The winter
weather advisory for the cascades in snohomish and king counties
was extended until 4 pm pst, today. This area could receive
another 3-6 inches of new snow by the end of the day.

Meanwhile, strong zonal flow aloft will prevail across the region
today. Look for a weak short wave ridge to move over the area
tonight. It looks like there may be a dry period across much of
the CWA tonight. Alas, another pacific storm will impact the
region on Tuesday for locally heavy snow in the mountains,
especially on the southwest facing slopes. A winter storm watch
may be needed for the cascades in pierce and lewis counties.

It looks like the cold or occluded front will stall as it becomes
parallel with the flow Tuesday night. Therefore, expect wet
weather with locally heavy precipitation to continue Tuesday
night through Wednesday. The snow levels will also rise into the
4500 to 5000 ft range across much of the area Tuesday night due to
warm air advection.

The cold or occluded front is anticipated to move across the cwa
late Wednesday afternoon or evening; although, the atmosphere will
undergo cooling ahead of the front as heights thicknesses lower.

Thus, anticipate snow levels to lower during the day Wednesday.

Long term from the prev discussion
Conditions will turn more showery Thursday as an upper level
trough moves into the region. This trough will be colder than
recent ones, with heights in the 530s. The snow level Thursday
night will fall to below 1000 feet in some areas, and overnight
low temperatures will be in the low to mid 30s. The upshot is
there could be a little lowland snow by Friday morning. Showers
will taper considerably later Friday and warm advection should
melt any snow on the ground.

The latest run of the GFS has periods of heavy rain over the
weekend, though not as much as in some previous runs. The euro is
similar. High pops with high temperatures in the 50s seem likely
Saturday and Sunday. Burke

Aviation A flat upper ridge axis will pass across western
washington this evening. As a result, shower coverage will be
diminishing, and the unstable air mass will become stable late
this evening. Overnight, easterly surface winds will develop and
dry out any remaining CIGS below about 030-050. A warm front will
arrive on Tuesday morning, bringing the arrival of rain and cigs
lowering mostly below 030 by late morning. Moderate westerly flow
aloft today will become strong southwesterly on Tuesday morning.

Ksea... With westerly flow aloft, the terminal will be near the
southern edge of an olympic rain shadow for the rest of today,
limiting any remaining showers today to short 10-15 minute
affairs. Most showers will be seen passing south of the terminal.

Any CIGS should be in the 035-050 range today. Showers will end
outright for the evening hours, and the development of a drying surface
easterly wind component will help to dissipate any remaining
clouds below 045 for the overnight hours. On Tuesday, a warm front
will spread rain across the terminal around 14z, and CIGS will
fall below 030 by late Tue morning.

Marine Moderate southerly onshore flow early this morning will
gradually ease through this evening. Small craft advisories
remain in effect for winds or seas along the coast and at the west
entrance to the strait through this evening, while residual small
craft advisory conditions continue over the strait and portions
of the puget sound.

A strong warm front will spread into the waters early Tuesday
morning, and a 985 mb low will pass northward out beyond 130w.

Easterly then southeasterly gradients will tighten and become
strong, so gales are expected starting early Tuesday morning over
the coastal waters, the strait, and up to near haro strait. Gale
warnings are now in effect to cover these zones.

Latest forecast models show a couple of small, but vigorous lows
rotating around an upper level low in the gulf of alaska and into
vancouver island on Wednesday and Wednesday night. Gales are
possible with these features, and seas in excess of 20 feet
developing on the south side of these lows will likely affect the
waters on Thursday.

Yet another in a series of strong systems will affect the waters
later Friday or Friday night into next weekend. Haner

Hydrology
The skokomish river in mason county was slightly above flood stage
at this time, and is forecast to fall below flood stage later this
morning. More rain Tuesday night could bring the skokomish river
above flood stage for another round of minor flooding.

Recent rainfall has brought the USGS landslide indices closer to
thresholds for shallow landslides, but the still thresholds have
not have been exceeded.

Flooding is unlikely on rivers other than the skokomish through
Friday. Some models showed heavy rain on the olympics and
cascades this weekend. This rain, if it occurs, could be heavy
enough for more widespread flooding. Burke 05

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.
