207 pm pst Fri feb 15 2019

Synopsis An upper level trough over the pacific northwest will
give a chance of showers to the area through Saturday. Showers
will decrease later Saturday into Saturday night as the upper low
moves off to the southeast of the area. Weak high pressure aloft
will give dry but cool conditions to the area Sunday into Monday.

A series of systems will give precipitation with low snow levels
over the area Tuesday through the remainder of the upcoming week.

Short term tonight through Monday A deep and cold vertically
stacked low off of the oregon coast is spinning some showers
across the area this afternoon, and the air mass over the coastal
waters is unstable enough that a thunderstorm was observed at 130
pm off of forks. This upper low will move off to the southeast of
the area tonight. Another upper low dropping southward through
west-central british columbia will take a similar path to the
first one later Saturday and Saturday night, and will produce
another chance of showers across the region. Snow levels will
generally be low, but above most of the lowland locations through
Saturday.

A 1046 mb high over NE british columbia will drop into the central
interior of bc Sunday night into Monday. Northeasterly pressure
gradients increase again late Saturday night into Sunday and the
bellingham wa to williams lake bc drop to around -12 to -17 mb.

This will refresh the cold air over western washington Sunday into
Monday giving dry but cool to cold conditions. Some models show a
brief period of flurries with the boundary associated with the
leading edge of this cold air, and a trace to half inch of snow
can't be ruled out Sunday morning before conditions dry.

Temperatures will be cold enough Sunday and Monday mornings that
any daytime melting of snow could result in some black ice on
roadways during the night and morning hours. Albrecht

Long term Tuesday through Friday The extended period will
generally be unsettled at times and snow levels will remain low,
generally below 1000 feet, through the period. Highs will average
in the 30s to lower 40s and lows in the 20s to lower 30s. These
temperatures are well below what would normally be observed in
late february.

Models generally show a weak system bringing some light
precipitation to the area on Tuesday, but the heavier band of
precipitation will come with a short wave trough that will be
coming in from the north Tuesday night and Wednesday. Models
differ on exact precipitation amounts and snow levels, but there
is the potential for many places in western washington to see some
snow accumulation with this system Tuesday night or early
Wednesday before snow levels rise to up to 1000 ft or so. Another
system with low snow levels is possible around Friday. Forecasts
generally follow a blend of model solutions for now. Albrecht

Aviation Southerly winds will continue as low pressure system
moves into oregon into Saturday. Wrap-around moisture will keep the
chance of scattered showers going into Saturday, though not
everywhere will see precipitation. Ceilings will bounce around
betweenVFR and MVFR through tonight, with most locations going down
to MVFR Saturday morning.

Ksea... CIGS will continue to bounce around betweenVFR and MVFR this
afternoon and evening. A few spotty showers are possible but not
expecting widespread activity. MVFR ceilings possible again Saturday
morning. Winds generally S SW under 10 kts. Ceo

Marine A surface low offshore will gradually drift inland over sw
washington and oregon tonight. Small craft winds across the inland
waters will gradually ease this afternoon evening. Large swell
across the coastal waters will remain above 10 feet through
Saturday. Winds across the coastal waters will ease a bit tonight
before increasing again Saturday. Have extended current small craft
to cover hazardous seas tonight and hazardous seas winds Saturday.

Weak low pressure will drift south Saturday night, ushering in gale
force fraser outflow winds across the northern inland waters Sunday.

Ceo

Hydrology Precipitation that falls through Saturday night will
mainly be in the form of rain, or a rain snow mix. The
precipitation, combined with all the snow on the ground that will
be melting over the same period, will result in some ponding water
on roadways and yards, especially with snow and ice plugging
storm drains. In addition, melting snow is efficient at saturating
the ground and is increasing the threat of landslides more than
the rainfall-based indices would suggest. The sps for the
landslide threat will be continued through Saturday.

As far as river flooding, none is expected for the next 7 days,
albrecht

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.
