area forecast discussion
national weather service seattle wa
859 am pst Sat feb 24 2018

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 A weather system will exit the area this morning.

Snow over the mountains will taper. The winter weather advisory is
scheduled to end at noon today and that looks on track. A puget
sound convergence zone sagging south through central puget sound
should break up later this morning. Outside of the convergence
zone, the lowlands will be mostly dry today in between weather
systems. There will even be some Sun breaks.

Another frontal system will move into the area later tonight and
push inland on Sunday. Snow levels will be low but onshore flow
should keep it warm enough for just cold rain in the lowlands.

The cascades will get a lot of snow - probably one to two feet.

The winter storm watch will be updated to a warning this morning.

There will probably be another pscz behind the frontal system
later Sunday.

An upper trough will settle over the area Sunday night and then
push a bit inland on Monday. A threat of lowland snow will return
again late Sunday night early Monday morning as snow levels lower
to near sea level. However, most of the area will be dry by then
with just isolated showers. New snow accumulations, if any,
should be light and isolated. Schneider

Long term Previous discussion... 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 northerly flow aloft today will turn westerly
tonight. At the surface, onshore flow today will increase tonight
after a front moves through the region. The air mass will be moist
with scattered rain or mixed rain and snow showers. A convergence
zone over king county this morning will dissipate by noon.

Ceilings are generally MVFR or ifr over the interior, withVFR or no
ceilings over western sections. A weather system will bring MVFR
ceilings with rain to all areas tonight.

Ksea... CurrentlyVFR conditions, but a weakening convergence zone
just north of the terminal this morning could bring MVFR ceilings
and MVFR visibilities in a mixed rain snow shower. The convergence
zone will dissipate by noon.VFR conditions after that, becoming
MVFR after 06z as rain develops. Southerly wind 8-12 kt today
increasing to 15-25 kt tonight. Chb

Marine Onshore flow will ease today, then increase tonight after
a front moves through the area. Small craft advisories are in effect
for most waters this morning. A gale watch is in effect for the
coast and strait tonight through Sunday.

Weak high pressure over the area Monday will be followed by another
front on Tuesday. Chb

Hydrology River flooding is not expected for 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.
