Synopsis A weak cold front will spread light rain across
western washington this morning as it moves southeast. An upper
level trough trailing the front will bring a few showers this
afternoon and evening. A warm front will spread more rain and
mountain snow across western washington Saturday, then a slow
moving cold front will keep Sunday wet at times. After a minor
lull on Monday, a deepening low center should pass across
southwest b.C. On Tuesday, possibly bringing windy conditions and
heavy mountain snow. Drier high pressure will build across the
pacific northwest next Wednesday and Thursday.

Short term A weak cold front will gradually move southeast through
western washington this morning. This front will be most notable
for producing the first rain since early last week, albeit light
rain in places. Radar already shows light bands of rain spreading
southeast through northwest washington early this morning. The
front will exit by early afternoon. Some onshore flow behind the
front will keep a few showers going into this evening, mainly in
the cascades and in a diffuse puget sound convergence zone. In
terms of cooling, the mountains will see the most cooling after
such a long stretch of warm air aloft.

Some flat upper ridging will rebound over the coastal northwest on
Saturday. This will push a warm front onshore. Rain and mountain
snow will spread onto the coast on Saturday morning then spread
inland later in the day.

As the ridge flattens and retreats to the south on Sunday, an
east-west oriented cold front will slowly sag in from the north.

The tail end of a shortwave in strong west flow aloft will enhance
lift along the front. With the slow movement of the front and
strong west flow aloft, heavier precip amounts are likely with
moderate snow accumulation in the mountains. The front will
eventually reach southwest washington on Monday evening before
turning up stationary. Haner

Long term The weather on Tuesday bears a watchful eye. A strong
shortwave will travel east along the leftover front just to our
south. Cyclogenesis is expected along the front on Monday between
130w and 140w. Under the influence of strong upper divergence,
the low will rapidly deepen while it tracks east on Tuesday to
central or southern vancouver island. The 00z ECMWF deepens the
central pressure by about 20 mb in 24 hours, and the 06z GFS is
not far behind. GEFS ensemble means show similar trend, so
confidence is good at this point. The 00z ECMWF shows the low
continuing to rapidly deepen below 995 mb as it crosses the b.C.

Coast range and passes our longitude. The continued strengthening
is key, because such lows bring stronger wind and more wind
impacts than lows that are weakening. Again, this setup bears
watching for wind impacts. In addition to wind, heavy mountain
snow appears likely thanks to a sharply defined trailing cold
front that will move across the area concurrent with the large-
scale forcing and lift of a deepening parent low.

Very cold air aloft will follow Tuesday pm's front, with 500 mb
temps falling to -34c on Wed morning. So plenty of post-frontal
convective showers and snow levels down to 2000 feet or less will
follow.

Later Wednesday, an upper ridge axis around 135w will strengthen,
amplify, and spread toward the pac nw. The air mass should quickly
stabilize. By next Thursday, northwest flow aloft with 500 mb
heights nearing 570 decameters along the coast should lead to dry
weather. All 20 members of the GEFS ensemble system show no precip
at sea next Thursday, so dried out the forecast for all but the
mount rainier area. Haner

Aviation A weak low pressure system and cold front will move over
western washington Friday morning. The air will become moist with
areas of light rain or showers developing. Southwest flow aloft will
become northwest later today. Areas of light rain or showers
tapering off by evening except for showers in the pscz.

Ksea... Clouds will thicken up with lowering CIGS as light rain or
showers develop this morning. A southerly breeze could shift to
northerly around 22z with a weak FROPA but variable is a good bet too
through evening as convergence sets up with some shower activity.

Marine A 1020mb low and cold front will move over western
washington this morning. Small craft advisory northwest winds
will develop over the coastal waters behind the front and then
spread into the strait of juan de fuca by evening. A warm front will
move through the waters late Saturday night into Sunday. Some small
craft advisory conditions are likely across the waters, especially
Sunday, as flow aloft interacts with the area terrain.

A deepening low will move onto central vancouver island on Tuesday
then move east more or less along the canadian border. Widespread
small craft advisory conditions are expected with this system and
gale force winds are possible over some waters.

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