area forecast discussion
national weather service seattle wa
634 am pdt Fri mar 22 2019

Update this morning Patches of fog have formed over valleys
of the south interior and on portions of the kitsap peninsula. A
quick forecast update was made to account for this fog that will
dissipate by 10 am. Albrecht

Synopsis A weak front will lift northeast across the area this
afternoon and evening bringing an increase in clouds and some
light rain to the area. Breezy to windy conditions can be expected
with the front this evening. Cool weather with showers can be
expected on Saturday as a weak upper trough moves across the
region. Then it will be dry on Sunday. Another front will bring
precipitation to the area on Monday. Then unsettled weather will
continue into next week.

Prev discussion issued 254 am pdt Fri mar 22 2019
synopsis... A weak front will lift northeast across the area this
afternoon and evening bringing an increase in clouds and some
light rain to the area. Breezy to windy conditions can be expected
with the front this evening. Cool weather with showers can be
expected on Saturday as a weak upper trough moves across the
region. Then it will be dry on Sunday. Another front will bring
precipitation to the area on Monday. Then unsettled weather will
continue into next week.

Short term today through Sunday ... A negatively tilted frontal
system that connects a system moving into central california with
a deep low in the gulf of alaska will lift northeastward across
the region this afternoon and this evening. Expect clouds to
thicken and light rain to spread into the area from the southwest
mainly this afternoon and evening. Mesoscale models continue to
show breezy to locally windy conditions developing this evening as
southerly pressure gradients tighten with the front, but winds are
expected to remain below advisory criteria.

Behind the front, expect partly cloudy to mostly cloudy conditions
with showers on Saturday as a weak upper level trough moves across
the area. At this time it appears that instability and upper level
diffluence will be greatest over western oregon on Saturday, so
will leave thunderstorms out of the forecast for now.

Low level flow will tend to become north to northeasterly on
Sunday as high pressure builds over southwestern british columbia
and the next negatively tilted frontal system approaches the area
from the southwest. So the idea of a dry day on Sunday still looks
good.

Temperatures in the short term appear that they will be near
normal for late march with highs in the mid 50s to lower 60s and
lows in the upper 30s to mid 40s for the most part. Albrecht
long term Monday through Thursday ... Models are consistent on
Monday in showing another frontal system lifting into the area
from the south and southwest. This will result in more rain later
Monday followed by a showery pattern later Monday night into
Tuesday. Expect temperatures on Monday to be slightly cooler than
normal with the precipitation, then near normal temperatures are
expected on Tuesday with the showers.

The forecast Wednesday and beyond gets more challenging as models
develop a strong ridge over the gulf of alaska allowing cool high
pressure over the northwest territories of canada to drop
southward into british columbia and alberta. At lower latitudes, a
strong jet stream continues to move into central and southern
portions of california mid to late week. Western washington is
left between the two streams with possible offshore flow - but
also possibly a frontal system camped over the area. No changes
were made to the forecast from Wednesday onward for now. Albrecht
aviation... Cloud cover encompasses the majority of the area this
morning as a frontal system slowly approaches the region from the
west. Recent trends in observations actually depict clear skies from
hoquiam over to olympia, with partly to mostly cloudy skies to the
east and north. Ceilings are largely MVFR andVFR and this should
continue into thru the morning hours ahead of the front. Will likely
see a few breaks in clouds at times. Winds early this morning range
from calm to S SE around 5-6kts.

As the front approaches the coast by the afternoon, additional cloud
cover is expected-mostlyVFR but some higher end MVFR is possible as
well. Along with the clouds, rain will begin to spread across the
area and winds will begin to pick up towards 10-12kts. As the rain
along the front pushes west to east Friday evening and Friday night,
rain will decrease in coverage and give way to scattered showers.

Ceilings may also drop to MVFR behind the front. Winds will maintain
a southerly component with speeds dropping back below 10kts.

Ksea... GenerallyVFR through the evening hours, with a few breaks in
the clouds this morning ahead of the front. Front will push into the
area this afternoon and evening, bringing rain showers. Rain showers
will taper into Saturday with a chance for MVFR CIGS early Saturday
morning. Winds generally south at less than 5kts, then increasing to
near 10kts this afternoon.

Marine... Increasing southerly winds this morning will result
in small craft advisory conditions most area waters through this
evening, with small craft advisory westerlies through the central
and east strait this evening. In addition, significant westerly
swell - 10 to 12 feet - will reach the coastal waters and west
entrance Friday night through Saturday. Winds and seas will ease
Sunday.

Hydrology... No river flooding expected over the next seven days.

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisory until 5 am pdt Sunday for coastal waters
from CAPE flattery to james island 10 to 60 nm-coastal

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
