Area Forecast Discussion
National Weather Service Seattle WA
855 PM PST Thu Feb 9 2017

.SYNOPSIS...Temperatures will gradually cool tonight and Friday as
a trough of low pressure aloft moves toward the area. A 990 mb
over the offshore waters will fill to about 995 mb as it moves
onto the south coast of Vancouver Island. The low will give rain
and windy conditions to most of the area as it passes on Friday.
An upper ridge will build into the Pacific Northwest this weekend
with dry weather likely through early next week. A front will
approach the area on Wednesday.

&&

.SHORT TERM...Showers continue to stream northeast across the area
this evening behind this afternoon's frontal passage. The central
Puget Sound area is mainly rain shadowed by the Olympics. In the
mean time, windy conditions in the central Puget Sound region
continues but is starting to wind down somewhat.

A 990 mb low centered over the Washington offshore waters will
lift northeast onto southern Vancouver Island Friday morning as it
fills. The latest NAM and HRRR solutions show windy conditions
redeveloping as the low passes with the 925 mb winds sufficient to
give gusts to 45 to 50 mph along the coast during the early
morning hours and in the Puget Sound area during the mid morning
to mid afternoon hours on Friday as winds aloft mix downward. The
wind advisory for the coast and the Puget Sound area zones will be
maintained.

Snow levels in the mountains are falling as the air mass aloft
cools with the approaching upper level trough. Snow levels will
fall to 2500-3000 feet on Friday then to 1500-2000 feet Friday
night. At this time, it appears that snowfall amounts will average
just below what would be required to require a winter weather
advisory, especially in the passes.

A ridge of high pressure will gradually build into the area Friday
night and Saturday with showers gradually decreasing. Offshore
flow and ridging aloft will give dry conditions starting Saturday
night.

Current forecasts are in good shape. No updates are required.
Albrecht

.LONG TERM...From the previous long term discussion: The upper
ridge will be over the region Sunday. A weak system will move over
the north side of the ridge into British Columbia, but Western
Washington should have partly to mostly sunny skies. The ridge
will move slowly east over the region Monday for another day of
dry weather. As it moves further east Tuesday, the next Pacific
frontal system will approach the Pacific Northwest. It could bring
rain to the coast Tuesday, but the interior of the forecast area
should have dry weather again Tuesday with a chance of rain
Wednesday.

&&

.AVIATION...Strong S/SW flow will continue tonight with scattered
showers across the area. The air mass is moist and slightly
unstable with MVFR to low-end VFR conditions. An upper level
trough will maintain showers on Friday as it moves inland. Expect
strong S/SW winds at the surface with gusts to 40 kt possible.
Showers will taper off and winds will ease Friday night as this
system exits. 33

KSEA...Showers in the vicinity tonight with gusty S/SW winds at
the surface to 25-30kt. MVFR cigs possible. Winds will increase
by 15-18z Friday with gusts to 40 kt possible. 33

&&

.MARINE...The combination of high astronomical tide and low
pressure will result in 1-1.5ft tidal anomalies early Friday
morning for the interior coastlines - a Coastal Flood Advisory is
in effect.

A deep surface trough and associated 990-995 mb surface
low will cross the Coastal Waters late tonight then shift inland
Friday morning. Gales are likely across most waters. Expect strong
onshore flow through Friday as the low tracks farther inland and
weakens. High pressure will bring a period of lighter winds on
Saturday. The flow will turn offshore on Sunday and continue
through early next week. 33

&&

.HYDROLOGY...Rainfall with Friday's system is not expected to be
hydrologically significant, and snow levels in the mountains will
gradually fall to below 3000 feet on Friday and 2000 feet Saturday
night.

Recent rainfall caused rivers across the area to rise and several
rivers have experienced minor to moderate flooding. Once the
crests have moved downstream to the mouths of the rivers, no
additional flooding is expected across the area for the next 7
days. Albrecht
