314 pm pdt Tue aug 20 2019

Synopsis An upper level ridge over the pacific northwest will
slide east through this afternoon as a front approaches the area.

The front will spread rain across western washington tonight
through Wednesday. Dry weather by Thursday afternoon with a weak
high pressure over the area. A series of systems will pass
generally to our north Friday into the weekend keeping
temperatures near normal and bringing a chance of showers mainly
to the coast and northern areas.

Short term tonight through Friday Satellite imagery shows
high clouds over western washington this afternoon ahead of the
next frontal system. Dry weather through this evening as the upper
level ridge slides east. Temperatures generally in the 70s to low
80s currently with a few mid 80s by this afternoon.

A fairly potent weather system near 45n 132w will move northeast
and track into the central b.C. Coast tonight. The front will
slide onshore a bit quicker than expected with showers chances
along the coast tonight pushing eastward into the puget sound area
by daybreak. Models still fluctuate on QPF amounts, but most
generally in the range of a quarter of an inch to possibly a half
inch in spots around the sound with around an inch along the
coast. The front will move quickly through western washington and
weaken over the cascades by evening. Mesoscale models highlight
the possibility for the development of a convergence zone over
snohomish king counties Wednesday night into early Thursday
morning. Drier weather expected with some sunshine by Thursday
afternoon as a weak area of high pressure builds over the area.

Temperatures will be cooler on Wednesday with highs in the 60s
with temperatures into the mid 70s on Thursday.

The upper level ridge over the area Thursday will become flattened
by Friday with the approach of another upper level trough.

Although the bulk of the energy with this system will generally be
north of the area, there will be a few showers possible across the
northern tier on Friday. Temperatures on Friday will be in the mid
60s to mid 70s across the area. Jd

Long term Saturday through Tuesday Another weather system
north of the area looks to bring a chance for pops on Saturday
with the GFS being a bit drier than the ecmwf. Onshore flow
expected through the weekend with temperatures near normal.

Guidance does suggest high pressure aloft building into the area
on Monday. Pattern change is possible heading into the middle of
next week if the current trends are maintained with higher
amplitude ridging over the pacific northeast and warmer
temperatures. Jd

Aviation An approaching frontal system has brought fairly
widespread mid and high level clouds this afternoon. Expect
increasing low level southerly flow most areas ahead of the front
late tonight. The front will reach the coast after midnight with
low clouds and rain spreading inland through the morning. Conditions
will remainVFR overnight with ceilings lowering to MVFR levels
along the coast after 06z followed by much of the interior 14-16z.

Ifr conditions are possible Wednesday morning at some locations as
rain moves onshore and inland.

Ksea... Mid and high level clouds withVFR conditions through
tonight. Ceilings will to MVFR levels after daybreak with rain as a
cold front moves into the central puget sound. Southwesterly winds 2
to 6 kt becoming 8 to 10 kt after 06z.

Marine Southerly winds over most waters tonight with weak onshore
flow through the strait. Increasing southerlies ahead of the front
will result in small craft advisory conditions most waters as the
front moves into the area tonight and Wednesday morning. Onshore
flow and westerlies will follow behind the front through the
remainder of the week with periods of small craft conditions
possible in the central and eastern strait. A weak front will brush
the area later Friday and Saturday with minimal affect on the
winds.

Hydrology The daily hydrology discussion has ended until the
start of the next rainy season; it will only be updated as needed
until then.

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.
