Area Forecast Discussion
National Weather Service Seattle WA
918 AM PST Tue Jan 14 2020
.UPDATE...Opted to not make any changes to the forecast this
morning, as the significant changes that the previous shift made
to the forecast are on track for now.
Water vapor imagery this morning reveals a few key things. A
fairly large shortwave trough can be seen digging around 150W and
45N, evidenced by strengthening jet dynamics on its upstream side.
Another, more subtle shortwave can be seen moving offshore the
northern BC Coast towards Haida Gwaii. Some moisture is being
picked up by model guidance in the 850-500mb layer along an
extensive sfc stationary boundary that lies roughly from offshore
the islands in the Haida Gwaii vicinity to just offshore Vancouver
Island and into the Olympics and South Puget Sound region of W
Washington.
Through the day today and into tonight, the aforementioned
shortwaves will begin to merge and push the layer of moisture
further along the frontal boundary. Moisture will increase rather
quickly along the frontal boundary later this as low pressure
also becomes enhanced along the boundary. Given that the boundary
is stationary initially this afternoon and cold air remains on
the north side of the front, enhanced precip will be snow.
Evidence of some decent WAA by this evening in the vicinity of the
Strait and Puget Sound, coupled by a strengthening LLJ will
likely allow for a band(s) of moderate to heavy snowfall along or
in the vicinity of the boundary. Hard to pinpoint exact locations
and this will likely become a nowcast event when the time comes,
but forcing appears to be strongest in the far northern King Co
and Snohomish Co area. Given the phased nature of the shortwaves
across the Pacific, a much stronger area of low pressure will
develop offshore in both the lower and upper levels, which will
push the boundary north as a warm front overnight tonight into
Wednesday morning, pushing the snow threat up towards the Canada
border.
Again, to emphasize in this update: Confidence is low on the
location of moderate to heavy snowfall, but there are good
indications of moisture becoming quickly enhanced along the
stationary boundary later this afternoon and into tonight. It will
be important to monitor the forecast closely into the afternoon
hours, particularly our social media feeds. Will refine the
details of the forecast in the afternoon package as well as the
upgrades to the Winter Storm Watch.
Previous discussion provides more details, with an update this
morning to the marine and aviation forecast.

.PREV DISCUSSION... /issued 322 AM PST Tue Jan 14 2020/
.SYNOPSIS...Light snow showers will continue this morning. A warm
front moving north across portions of the area will bring another
round of lowland snow through Wednesday morning. The next system
moves in Wednesday PM into Thursday with a chance for lowland snow
and gusty easterly winds through the Cascade gaps and foothills.
A trend toward warmer conditions and lowland rain will develop
late in the week and into the weekend.
&&
.SHORT TERM /TODAY THROUGH THURSDAY/...Latest hi-res guidance
keeps snow shower activity going through the morning into the
early afternoon hours. As has been the case overnight, it's going
to be scattered in nature. This means light accumulations where
showers form and no snow for others. Pinpointing exact
accumulations then becomes tricky/futile. But even a dusting on
untreated roads is enough to cause some issues, especially for the
morning commute. Social media and spotter reports reveal that
there's a layer of ice under dusting of snow in a lot of spots so
expect slick conditions to continue. Morning commuters may want to
leave themselves some extra time and prepare for road conditions
that can change rapidly over small distances.
A bit of a break for most places outside the mountains later this
afternoon though a few showers will continue. The next item of focus
becomes a warm front lifting north from parent low out over the
Pacific. Latest model trends are concerning and have made some major
changes to the forecast this morning. Still some disagreement
between hi-res solutions and ensembles on starting point of warm
front as it lifts north but general consensus is from just south
of the Strait of Juan de Fuca over to somewhere in northern King
or Snohomish counties during the evening hours, then lifting north
into Skagit, Whatcom and eventually BC Canada by Wednesday
morning. 6Z model runs aren't all the way in, but a quick peek
suggests the trend is even a bit further south of the 00Z runs
which obviously has implications for the Seattle metro area. As
the band lifts north, locations could see a pretty good burst of
moderate to heavy snowfall. This would have substantial impacts to
travel. Have upped precipitation amounts and resulting snow
forecasts but amounts could be higher than currently indicated,
especially in favored upslope areas along the Strait and if the
band starts out further south. Also could see some enhancement as
moist southerly air meets northeasterly cold Fraser outflow up
north. As such, will be issuing a winter storm watch for a good
portions of the lowlands from about Seattle northward and along
the coast and Strait. Near-term trends will need to be monitored
very closely today as uncertainty in heaviest snow placement
remains high and changes to the forecast will likely occur.
As cold Fraser outflow continues across western Whatcom and San Juan
counties, very cold wind chills will persist. South of the warm
front, dry weather is expected overnight.
Low pressure system centered around 50N and 135W then moves NE
toward the northern tip of Vancouver Island Wednesday into Thursday.
As a result, offshore flow and surface pressure gradients across the
Cascades strengthen. Current model solutions put the SEA-EAT
gradient between -11 to -15 mb. This would point to a bout of strong
easterly winds through the Cascade gaps into the foothills later
Wednesday into Wednesday night. Still some uncertainty in the
details but current forecast suggests gusts of 45 to 55 mph. This
would likely lead to power outages and tree damage, especially with
heavy wet snow currently in place. Outside of the winds, another
round of precipitation will rotate through the area. On current
track, bulk of moisture moves into Vancouver Island with
precipitation more showery in nature over Western Washington
Wednesday afternoon into Thursday. Downslope winds may limit snow
chances for portions of the Puget Sound lowlands. On the flip
side, this type of pattern also enhances snow in ares such as the
Kitsap Peninsula, Hood Canal and eastern slopes of the Olympics.
East winds may also lead to localized banding of snow as well even
in the lowlands. Snow levels remain a bit tricky and could
fluctuate between the surface and 1000 feet on Thursday. All this
sums up to the main message that snowfall accumulations with this
next system will be highly variable and forecast will change as
mesoscale details evolve in the near term. Regardless, area
residents should prepare for snowy travel at times with possible
power outages and tree damage for Cascade gaps and foothills.
Overnight lows on Wednesday and Thursday nights will be a bit
warmer but still near the freezing mark which would be quite
chilly for those without power.

.LONG TERM /FRIDAY THROUGH MONDAY/...Showers linger into Friday
morning as associated trough swings through the area. Any break
between systems will be short lived as next system moves through
the area into the weekend. Temperatures will warm substantially so
looks like a rain-maker for the lowlands. Rising snow levels are
expected so will need to monitor the potential for flooding if
heavy rain falls on existing snowpack in foothill locations and
below. Details will be refined.
CEO
&&
.AVIATION...A broad upper trough over the area will shift inland
today. A broad upper ridge will build over the area tonight with a
warm front lifting north through the area. At the surface, Fraser
outflow will weaken today then increase again tonight as the warm
front arrives. The air mass is moist and stable.
There will be a mix of low and mid clouds today with scattered
snow showers. A band of heavier snow will likely set up across
over the Olympic Mountains and Strait of Juan de Fuca into Central
Puget Sound late this afternoon or early this evening and then
lift north into Canada tonight and Wednesday morning.
KSEA...Low clouds today with a few flurries. A band of heavier
snow will develop north of the terminal this evening then lift
north. The best estimate for now is the terminal will see little
if any snow accumulation from this feature. The winds will be a
bit hard to pin down today - probably northerly for the most part,
then turning southerly tonight.
&&
.MARINE...An area of low pressure offshore is expected to
rapidly deepen from near 998 millibars tonight to near 975
millibars by Wednesday evening as it lifts northeastward. This
will generate strong winds across much of the waters with gale
force winds expected and possible storm force possible over the
coastal waters Wednesday night.
Coastal seas will build to 17 to 20 feet Wednesday night. Winds
will ease as the low moves onshore over Vancouver Island on
Thursday. A very active pattern will continue into the weekend.
&&
.HYDROLOGY...At this point, river flooding is not forecast
through at least Friday. Rising snow levels in combination with a
round of heavy lowland rain possibly moving into the region Friday
into Saturday may lead to sharp rises on some area rivers this
weekend. Continue to monitor the latest forecasts this week.
