Synopsis
A warming trend will take place through Tuesday across the region
as a ridge of high pressure builds in. This will be brief as a
trough of low pressure pushes in from the pacific into central bc
and provides cooler temperatures and rain across the region
through Wednesday night. A weak high pressure will build back into
the region for the late week with temperatures near normal. There
may be a few showers around on Saturday, but otherwise it will be
a mainly dry stretch of weather to close out this week.

Short term tonight through Thursday
Clouds have been slow and stubborn to fully dissipate, although
most areas have at least developed Sun breaks at this time and
many areas have become mostly sunny. Temperatures are running from
near to slightly below normal at this hour with 60s and lower 70s
across the area. A mid level trough of low pressure will slide
northeast out of the pacific from later tonight into Tuesday.

Ahead of the system, increasing 500mb heights across western
washington will set the stage for a warmup tomorrow. Highs will be
a good 5-10 degrees warmer than today, with many low 80s
developing. Skies will be sunnier as well, but should steadily
cloud up from west to east in advance of this approaching system.

The system will bring rain to the coast by early Wednesday
morning and spread steadily east through the afternoon hours.

Heaviest rain totals will be on the olympic peninsula to the coast
with lighter amounts farther east. Temperatures will remain
mainly in the 60s on Wednesday with the clouds and showers. While
this system has plenty of moisture, it looks to remain progressive
as the trough axis crosses the area by late Wednesday afternoon
and conditions become just showery overnight Wednesday with
chances diminishing by daybreak Thursday.

Heights remain relatively high on Thursday and even begin to
increase again as a strong ridge over the eastern pacific builds
south of the area. The ridge will not make too much northern
progression this week however as a trough well to the north will
hold it at bay and keep more of a flat ridge or zonal flow in
place. This will mean Thursday should be near normal with
decreasing cloudiness.

Long term Friday through Monday
For the extended portion of the forecast, the zonal flow will
continue with a strong mid level ridge staying well south of the
area. Some indication of possible showers on Saturday but the
bulk of the system should remain north and so will include only
small chances of rain on Saturday. Either way, temperatures will
linger around normal through the weekend, in the upper 60s and
lower 70s. By early next week the focus will begin to shift on
northward expansion of the strong ridge to our south. This may set
the stage for an eventual return to hot weather to close out
august. Although this is a little past the current forecast
period, it is worth noting that CPC highlights the area for a risk
of excessive heat the last few days of the month. Will have to
continue to monitor this possibility but there is a lot of time
between now and then where the forecast may change.

Aviation Light low level flow into Tuesday morning. Westerly flow
aloft becoming southwesterly tonight and Tuesday.

Clouds continue to thin over much of the area this afternoon
although a lingering patch of stratus remains over portions of the
coast. Otherwise... All obs are indicating widespreadVFR conditions.

Given weak low level flow expected tonight and into Tuesday
morning... Extent of marine stratus will be limited to the coast
including hqm... Possibly extending to olm. The remainder of W wa
should see clear skies starting tonight and continuing into Tuesday.

Ksea...VFR conditions with continued gradual improvement as clouds
continue to scatter. Clear skies expected overnight. Southwest winds
will become northerly around 00z. Wind speeds will be generally
around 5 knots. Smr

Marine Light low level flow tonight becoming southerly and
increasing Tuesday as a front approaches the waters. The well
organized front will move through Wednesday with small craft
advisory southerlies still expected to occur ahead of the front over
the coastal waters, entrances to the strait of juan de fuca and
northern inland waters and post frontal small craft westerlies in
the strait. Models remain consistent in this feature... But as these
wind speeds still fall in the third period... Will leave headlines to
future shifts. High pressure will build over the coastal waters
behind the front Thursday. A weaker front will move by to the north
later Friday. Smr

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

Sew watches warnings advisories
Wa... None.

Pz... None.
