830 pm pdt Fri aug 23 2019

Synopsis A trough of low pressure will slowly move across central
bc through the weekend bringing a few showers and near to below
normal temperatures to western washington. The trough will slide
east and high pressure will build in behind it by Sunday and into
early next week. Low level offshore flow will develop by mid week
and produce well above normal temperatures and dry conditions.

Short term tonight through Monday Current radar shows most of
the shower activity that had been in place over portions of W wa
this afternoon and evening... Mainly over skagit and whatcom
counties... Has moved eastward and as such precip over the area has
generally come to an end. The weaker echoes currently present on
radar at the time of this writing are likely low clouds as onshore
flow will continue to keep moisture over the area. This break in the
action is expected to be short-lived though as rain showers should
develop again off the coast late tonight and likely reach the coast
by sunrise on Saturday. There will be a low chance for showers
across the area on Saturday with the greatest chance being over the
olympic peninsula and coast earlier in the day. This activity will
not be significant but the showers and clouds will help to keep
temperatures below normal for many areas on Saturday. The troughing
will be slow to move east and leave the area open for a few more
showers Sunday across the far northern areas closest to canada. But
otherwise it will remain cloudy with highs lingering near normal.

A change in the pattern will take place overnight Sunday and into
Monday. The trough of low pressure will finally exit well east of
the area. This will permit a ridge of mid level high pressure
which has been lingering well south of the area to begin building
north. Heights will rise quite a bit overnight Sunday and into
Monday and so Monday will be a much drier day with temperatures
bumping up about 5 degrees from Sunday to reach near or slightly
above normal. Smr johnson

Long term Tuesday through Friday From previous
discussion... This warming trend will continue through midweek.

Heights will continue to climb and crest in the 585-588dm range.

850mb temps will climb as well to around 18-20c by Tuesday evening
with winds becoming more favorable for supporting low level warmth.

Highs on Tuesday are expected about 10 degrees warmer than Monday,
so should be well above normal with lots of Sun and lower to mid 80s.

Wednesday looks to be the hottest day at present as 850mb temps
crest in the +20 to +23c range with low level offshore flow. This
suggests highs in the mid to upper 80s with readings near 90
possible from seattle to the south for some late summer heat.

Current heat impact levels indicate some impacts for vulnerable
populations but not hot enough for more widespread concerns at
this time. Record highs for seattle on t-w-th are 88,95,91 and so
those appear to be safe.

Thursday looks set to be a cooler day, by at least a few degrees
if not more. Heights fall and 850mb temps do as well. There is
some suggestion of some precip even in the area so the temperature
drop may be even more than current forecasts indicate. At present
have shows the greatest cooling on the coast and a few degrees of
cooling inland but will have to monitor trends in the extended.

Friday at this point looks like it may remain above normal across
the interior so have left forecast highs in the 80s as the details
on breakdown of the warmer pattern looks to be a bit in question.

Aviation Westerly flow aloft will remain over W wa tonight and
into Saturday morning before becoming more northwesterly Saturday
afternoon as an exiting upper level trough continues to move
eastward. Onshore flow will persist near the surface.

Cigs over W wa mostlyVFR at the time of this writing and expected
to stay that way with only mid to high level clouds forecast for
most of the area tonight and into Saturday morning. The exception to
this will likely be hqm and olm... With low level stratus expected to
develop there with the combination of moisture and onshore flow in
place. Mid level clouds will increase late Saturday morning and into
Saturday afternoon with a passing dissipating front.

Ksea...VFR ceilings will continue tonight and through most of the
overnight hours. A few MVFR stratus may move into the vicinity of
the airfield by daybreak Saturday. Winds N NE tonight before veering
s SW by Saturday afternoon. Wind speeds expected to remain under
10kts. Smr

Marine Onshore flow will persist as higher pressure remains
located offshore and lower pressure remains inland... Giving rise to
the potential for small craft advisory level winds in the strait and
portions of the northern inland waters tonight. Obs not bearing this
out just yet... But winds at race rocks starting to get close... So
will continue to monitor but will leave inherited headlines in place
for evening forecast issuance.

Winds will ease across these waters Saturday morning tho there
could be an observation or two of small craft winds in the strait
between 12-18z . Onshore flow will continue with little change in
the synoptic pattern, although a weak front will cross the local
area. In its wake, a stronger westerly push down the strait is
possible. Winds in latest guidance are capped at 30kts or below so
will hold off on a gale watch but the evening and midnight shifts
may need to issue if gradients continue to look strong.

Onshore flow looks to continue through Monday before shifting to
offshore as a thermal trough builds north from california. The
offshore flow pattern may then last thru much of the week.
