area forecast discussion
national weather service seattle wa
836 pm pdt Mon aug 19 2019

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 b.C. 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 Mild conditions in place
tonight with just few to scattered cirrus clouds aloft.

Temperatures will be a few degrees cooler Tuesday morning with
lows mostly in the 50s. The current forecast is on track. 33
previous discussion... 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 Previous discussion... 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 Dry conditions tonight and Tuesday with a ridge moving
into the pac nw. The flow aloft is southwesterly. Morning low
level stratus clouds will likely be limited to the coast.

Otherwise, expectVFR conditions. Rain may reach the coast late Tuesday
night or early Wednesday as a cold front approaches. 33
ksea...VFR conditions tonight with N NE wind around 5 kt. Winds
becoming S to 10 kt by 18z tues. 33

Marine Light low level flow will continue tonight. Southerly
wind will increase Tuesday night as a cold front approaches the
region. Expect small craft advisory winds over most waters. The
flow will turn westerly and onshore on Wednesday as the front
moves through western wa. High pressure will build over the
coastal waters on Thursday. A weaker front will move by to the
north later Friday. 33

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.
