950 am pst Sat nov 17 2018... Corrected

Synopsis A dry weather pattern with areas of night and morning
fog will persist into early next week. Overnight temperatures
will be on the cooler side, dropping into the 30s and even upper
20s by Sunday morning at some locations. A series of weather
systems will bring wet weather by the middle of next week through
the holiday weekend.

Short term A strong ridge of high pressure will maintain dry
weather over the pacific northwest through at least Monday or
Tuesday of next week. Offshore flow will increase today with a
1038 mb surface high over southern british columbia extending east
of the cascades. The flow is more northerly this morning with the
pdx-bli gradient around -5 mb. Meso models show northely winds
picking up this afternoon, around 10 to 20 mph. Drier air is already
filtering into the area, with only patchy fog coverage this morning.

This will clear out over the next couple hours with mostly sunny
skies the rest of the day. Highs will reach the low 50s.

Little change in temperatures or the overall weather pattern is
expected through Monday. The flow will become more easterly tonight
through Monday, allowing the northerly breeze to ease. Radiational
cooling will be more efficient, with temperatures falling into
the 30s or below freezing in cold pocket locations like olympia and
shelton. While drier air is filtering into western washington,
cooler low temperatures should allow fog to increase in coverage the
next couple days. However, offshore flow and lower dew points will
hinder widespread development. Fog or freezing fog may be locally
dense in prone valleys, especially around the southwest interior and
the interior south puget sound. Highs Sunday and Monday will reach
the low to mid 50s with any morning fog burning off by early
afternoon. Mercer

Long term Previous discussion... Tuesday looks like the last dry
day for awhile. A weather system will approach the coast during the
day, and clouds will increase across the area. Highs on Tuesday will
again be in the low to mid 50s. The GFS and euro differ slightly
about when the rain will begin, with the euro a bit slower. It does
seem rain will start some time on Wednesday, so have kept the
forecast of rain likely for Wednesday.

Model timing varies quite a bit after that, and so do the forecast
tracks of the various fronts, with the euro sending most of the
energy into oregon and the GFS moving the fronts right through
washington. For now a the forecast is for rain at times, with high
pops but relatively low qpf, and there will be some dry periods
between fronts. Highs will be somewhat lower than what we have been
experiencing, mostly in the 45 to 50 range. The snow level will fall
to 4000 to 5000 feet, which means most ski areas and passes will get
snow at times. Burke

Aviation High pressure and offshore flow will lead to dry and
stable conditions across western wa. The flow aloft is northerly
with E NE winds at the surface. There is patchy shallow fog in
the interior this morning which will scatter out by the afternoon.

Otherwise, expectVFR conditions. Patchy low clouds will likely
reform overnight. 33
ksea... Patchy low clouds near the terminal this morning will
scatter out forVFR conditions. N NE winds to 8-12kt. Dry
conditions tonight. 33

Marine Offshore flow will prevail across western wa through
early next week due to strong high pressure east of the cascades.

Winds are N NE over the waters with small craft advisories in
effect, specifically for the west entrance and adjacent coastal
waters, northern inland waters, puget sound and hood canal. Winds
will ease late this afternoon. The next frontal system will
approach the region on Tuesday then split and weaken as it moves
inland on Wednesday. 33

Hydrology High pressure is expected to maintain the dry weather
pattern through around Tuesday of next week. A parade of frontal
systems will affect the region starting around Wednesday of next
week through the holiday weekend. Models show a progressive and split
flow pattern, which will tend to weaken these systems. Rain amounts
with each system do not appear to be sufficient to cause flooding on
area rivers. River flooding is not expected on area rivers through
the next 7 days.

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisory until 4 pm pst this afternoon for coastal
waters from CAPE flattery to james island out 10 nm-
northern inland waters including the san juan islands-west
entrance u.S. Waters strait of juan de fuca.

Small craft advisory until 5 pm pst this afternoon for puget
sound and hood canal.
