What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis Increased marine clouds and cooler temperatures Thursday
and Friday will give way to warmer and sunnier weather over the
weekend before cooler and cloudier conditions return early next week.

Short term Tonight through Saturday... Water vapor satellite
imagery reveals a shortwave trough moving northeastward across
southwest oregon. Plenty of showers and thunderstorms developed in
advance of this feature across the oregon and washington cascades
earlier this afternoon and evening. Speed shear was rather meager
across the area today, which led to updrafts struggling to sustain
themselves. A thunderstorm in the southern lane county cascades where
0-6km shear was slightly greater likely contained the largest hail of
the afternoon based on doppler radar signatures. However, we have not
received any ground truth reports verifying whether or not large hail
was observed under any of the thunderstorms in which warnings were
issued this afternoon and early this evening.

Several convective allowing models including members of the href and
hrrr suggested thunderstorms were a good possibility for the portland
metro this evening. Several updrafts (in the form of towering
cumulus) went up around the portland metro during the time the sea
breeze arrived, but no individual updraft could sustain itself for
reasons not completely known at this point. A few models have
continued to suggest elevated thunderstorms are a possibility
between 8-11pm this evening as the marine layer deepens and is able
to interact with the instability still present above 5000 feet.

Given few signs this will materialize per latest radar and satellite
imagery, it appears the chance of thunderstorms is certainly
diminishing across most of the area. Will maintain a slight chance
of a thunderstorm through the late evening hours to account for the
uncertainty, though.

Otherwise, the marine layer is quickly spreading into the willamette
valley with temperatures already in the low to mid 60s in
kelso longview, mcminnville, salem and eugene. Expect marine clouds
to push well into the cascades by daybreak on Thursday with sunshine
returning in the mid to late afternoon hours. Temperatures will be
slow to warm with high temperatures likely only topping out in the
mid 70s. Expect a near repeat Friday before upper level high pressure
shifts over the region on Saturday and results in fewer morning
clouds and afternoon temperatures approaching 80f in the willamette
valley. Neuman

Long term Saturday night through Tuesday night... A surface thermal
trough strengthens along the n. Ca and s. Or coast Saturday night as
high pressure dominates inland, and offshore flow should keep marine
clouds off the coast Saturday night. A sunny start Sunday will allow
slightly warmer temperatures Sunday afternoon with high temperatures
remaining above the seasonal normals. Models are in excellent
agreement that an upper level trough will send a series of shortwave
troughs over the region Sunday night through Tuesday for increased
morning clouds and cooler afternoon temperatures. ~tj

Aviation Thunderstorms are starting to diminish across the area
this evening as cooler marine air fills into the interior. Will keep
vcts in the TAF for kpdx and khio for the next hour or so due to the
storm near khio, but suspect it will not impact either terminal.

Otherwise, the interior will see marine stratus continue to fill
into the valley tonight, with MVFR CIGS expected at all interior
terminals by 11z. Low stratus in the interior is expected to lift
early Thursday afternoon, with conditions becomingVFR by 21z.

Strengthening onshore flow will keep the coast socked in with marine
stratus tonight and Thursday. Will see predominately MVFR CIGS along
the coast the next 24 hours, but several hours of ifr CIGS are
possible late tonight early Thursday morning as high pressure builds
into the coast.

Kpdx and approaches...VFR conditions continue through late tonight,
with isolated thunderstorms possible for the next hour or so. MVFR
stratus around 2500 ft is expected to move into the terminal by 10z.

MVFR CIGS are expected to persist through early Thursday afternoon,
but should lift and becomeVFR by 21z. 64

Marine High pressure continues to sit over the NE pac, with
weak gradients over the waters through Friday. As the thermal
low starts to strengthen over norther ca this weekend, we could
see northerly winds ramp up to 20 to 30 kt over the weekend.

Seas remain around 3 to 5 ft through Friday as we remain under
relatively benign conditions. With winds ramping up this weekend,
seas may build up to 5 to 7 ft by late Sunday-early Monday, and
seas may become choppy. -mccoy
