Area Forecast Discussion
National Weather Service Seattle WA
1021 AM PST Wed Feb 1 2017
.SYNOPSIS...High pressure aloft with low level offshore flow will
keep conditions dry through Thursday. Expect a weakening warm
front to approach the area Thursday night for a threat of
precipitation. There is a possibility for brief light freezing
rain in the lowlands early Friday morning. The front will lift
north across the area later Friday morning. Warmer southwesterly
flow aloft through the weekend with a couple of systems moving
through the area.
&&
.SHORT TERM...Satellite imagery shows just a few high clouds over
Lewis county and southern Thurston and Grays Harbor counties
otherwise clear skies over Western Washington this morning.
Temperatures are recovering slowly from a cool start with mid 20s
to mid 30s common at 9 am/17z.
A couple of sunny days coming up for Western Washington with a
clear and cold night in-between. Upper level blocking pattern
continuing offshore with an upper level ridge off the British
Columbia coast and an upper level low near 37n/137w. At the
surface high pressure remaining over the interior of British
Columbia extending south over Eastern Washington. KBLI-CYWL
gradient down to near -11 mb at 17z. Models have the gradient
bottoming out around in the -13 to 14 mb range later today with
the gradient remaining below -12 mb into Thursday morning. This
will keep windy northeast winds going over the Northwest Interior
into Thursday morning. KOLM-KBLI gradient remaining between -3 and
-5 mb into Thursday as well for breezy Northerly winds for most of
the remainder of the interior. Highs both days even with the
sunshine will be a few degrees below normal, in the upper 30s to
mid 40s. Lows tonight will be cold with all locations below
freezing and the colder spots getting down into the teens.
Changes in the pattern taking place Thursday night as the upper
level high moves north and the upper level low moves northeast
towards Western Washington. Warm front spinning out of the low
approaching the area late Thursday night. Timing of the onset of
the precipitation associated with this feature will be critical.
If the precipitation arrives around 12z Friday there is a chance
of the precipitation being in the form of snow or brief freezing
rain. If the precipitation arrives later in the morning the air
mass will be warm enough for most of the precipitation to fall in
the form of rain. Current forecast more in line with the 00z model
runs with the precipitation starting in the south Thursday night
with a wintry mix of snow and freezing rain mix possible with the
precipitation spreading north into the Puget Sound area early
Friday morning. First look at the 12z NAM and GFS indicating a
little bit slower timing of the onset of the precipitation and
also less in terms of amount of precipitation. Will wait for the
12z ECMWF solution before making changes to the forecast package
but if the trend in the solutions continues will back off on the
extent of the freezing rain in the afternoon package. Air mass
warms up quickly on Friday with the precipitation type all rain by
Friday afternoon with the exception of perhaps Whatcom county.

.LONG TERM...Previous discussion follows. The weather pattern
will be wet and active during this period, and it appeared that
the mountains could receive significant snowfall. Temperatures
will be below normal.
&&
.AVIATION...Light to moderate easterly flow aloft will become
southerly on Thursday as an upper low approaches the Pacific
Northwest. Surface high pressure east of the Cascade crest and over
southern British Columbia will cause gusty northeasterly winds
through tonight. Strongest winds will be near coastal gaps, Cascade
gaps, and areas exposed to Fraser outflow across the north interior.
The air mass is dry and stable.
KSEA...Mostly clear today. North-northeasterly wind 10-15 knots with
gusts to 25 knots...except rising to 15-20 knots with gusts to near
30 knots for a few hours later this afternoon. dtm
&&
.MARINE...Northerly or offshore flow is rapidly increasing this
morning. Expanded Gale warnings to most waters through tonight.
Strongest winds will occur near coastal gaps, in the Strait of Juan
De Fuca, and areas exposed to Fraser outflow across the northern
inland waters. Winds more northerly in Puget Sound and Admiralty
inlet...rising to 15 to 30 knots this afternoon and tonight.
Offshore flow will begin to ease and turn more easterly later
Thursday as high pressure over British Columbia moves off to the
southeast. A frontal system will move through the waters Friday
and Saturday. Another surface trough will affect the waters on
Sunday. dtm

.HYDROLOGY...River flooding is not expected over the next 7 days.
