Synopsis Cool and unsettled weather will continue through the
end of next week. Next system arriving tonight into Sunday. Low
level onshore flow ahead and with the system will lift the snow
levels above the surface. A brief break in the action on Monday
before the next system arrives Monday night and Tuesday. A much
wetter system will arrive Wednesday night or Thursday.

Short term Satellite imagery shows upper level shortwave moving
into western washington early this morning. Low level onshore flow
has kept temperatures in the mid and upper 30s for the last few
hours with the exception of some cool air still trapped in
northeast portion of whatcom county.

Shortwave moving through western washington this morning. In
addition to the warmer temperatures dew points are in the lower to
mid 30s this morning. Outside of northeast whatcom county not
looking for any snow accumulations this morning in the lowlands
although with the heavier showers could see a rain snow mix.

Another inch of snow possible early this morning in northeast
whatcom county. Showers will decrease later this morning into the
afternoon hours with shortwave moving off to the east. In the
cascades another 4 to 6 inches of snow this morning will keep the
advisory up until noon.

Yet another in the series of weather system embedded in the north
northwesterly flow aloft moving into western washington late
tonight into Sunday. Good orographics with this system. Model 850
mb winds westerly at 25 to 40 knots with the stronger winds over
the central and southern cascades. A winter storm watch is up for
the cascades beginning tonight and continuing into Sunday. Will
stay with the watch in the morning package per coordination with
the portland office. If there are no changes in the 12z model run
look for the watch to get upgraded to a winter storm warning.

Onshore gradients increasing as the system approaches lifting the
snow level up to around 1000 feet. Kolm-kbli gradient peaking in
the early morning hours on Sunday near plus 6 mb so expect breezy
to windy conditions later tonight into Sunday morning. System
dropping south of the area Sunday afternoon with just scattered
showers over the area. Convergence zone developing Sunday morning
will continue into the afternoon hours. With westerly flow aloft
and strong southerly gradients expect the convergence to remain in
snohomish county. Highs on Sunday will be in the upper 30s and
lower 40s.

Cool upper level trough settling over western washington Sunday
night with shower activity decreasing. Convergence zone could sag
south Sunday evening as the flow aloft becomes more northwesterly
and the southerly surface gradients weaken. Snow levels lowering
back down to 500 feet or less but outside of the convergence zone
moisture will be limited. Lows Monday morning will be in the lower
to mid 30s.

A little bit of a break in the action on Monday with the cool
upper level trough to the south and northerly flow aloft over the
area. Can't rule out a shower at this point but if the trends
continue most of the area could squeeze out a dry day Monday.

Highs with some sunshine will be in the lower to mid 40s.

Long term Extended models in pretty good agreement this morning
with yet another system embedded in the northwest flow aloft
moving over the area Monday night into Tuesday. 00z model runs a
little wetter, warmer and stronger with the next front arriving
Wednesday night into Thursday. Cool upper level trough moving back
over the area Thursday night into Friday with another low snow
level scenario with showers. Felton

Aviation Moderate northwest flow aloft will continue today
before turning more westerly early Sunday morning. An upper trough
will move southeast across the area this morning. The air mass will
be moist, mainly below 10,000 ft. At the surface, moderate southerly
flow will continue.

Cigs this early morning generally a mix of MVFR to ifr
conditions... With clm and hqm proving to be outliers currently
reportingVFR conditions. As showers continue to move through the
area associated with the aforementioned upper level trough... Would
expect widespread MVFR to ifr conditions to persist through at least
the mid-morning. Late morning and afternoon should see improvement
into MVFR toVFR conditions as trough and showers exit the area. A
shortwave disturbance looks to enter the area tonight which may drag
cigs down slightly... With mostly MVFR conditions expected overnight
tonight.

Ksea... South to southwest winds this morning 10-15 kts with some
gusts up to 23 kts possible. Winds will ease into the 7-12 kt range
this afternoon and see direction shift somewhat to the west to
southwest... Returning to southerly in the evening. CIGS in ifr
conditions at the time of this writing as showers move through. May
see CIGS improve during dry gaps to MVFR conditions. More
substantial improvement will wait until the late morning or early
afternoon whereVFR CIGS will be possible. Smr

Marine Strong onshore flow will ease this morning. A strong
system will impact the region tonight and Sunday with gales
possible - gale watches are in effect. Seas will also build to 12
to 18 feet during this period. Weak high pressure will bring
lighter winds on Monday. Another cold front will arrive on
Tuesday. 33

Hydrology River flooding not expected in the next 7 days.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
