Version 3.4
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 Today will be dry and any clouds should dissipate.

Onshore surface flow will increase tonight, bringing marine clouds
inland along with areas of drizzle Saturday. The pattern will remain
similar through memorial day. Next week will be a little cooler.

Short term There are clouds over most of the interior this
morning, but the coast, olympics, and northwest interior are mostly
clear. Most of the cloudiness will evaporate this afternoon and
especially this evening. Little if any drizzle will fall out of the
clouds today. Highs today will be 65-70 over the interior, with
lower 60s on the coast.

Onshore flow will increase tonight. Westerly gales are likely in the
strait tonight, and marine stratus will arrive over the interior
late tonight. The marine layer is likely to be thick enough to
produce areas of drizzle. High temperatures will again be in the 60s.

Onshore surface flow will weaken considerably Saturday night and
Sunday. This will mean fewer clouds and no drizzle on Sunday. With
plenty of sunshine, temperatures will be higher, with mid 60s on the
coast and low to mid 70s inland. Burke

Long term Previous discussion... Memorial day is still expected to
be dry, and temperatures should be about the same or slightly lower
than on Sunday. So, it still looks like a nice day for outdoor
activities.

The GFS and canadian models were now close to the ECMWF solution
in regards to the timing of the midweek system. Thus, the ecmwf
was the model of preference for this period (memorial day thru
Thursday). Expect onshore flow to strengthen on memorial day in
response to the approaching upper level trof. This trof will move
the area on Tuesday for cooler and cloudier conditions. The models
were drier with this system; therefore, decided to confine the
mention of showers to the puget sound convergence zone and the
north cascades.

The pacific northwest will remain under the influence of low
pressure aloft Wednesday through Thursday for below normal temps.

There will be a chance of showers over mainly the mountains and
within the puget sound convergence zone.

Aviation The tail end of a weak upper trough will brush by
western washington late today. This will strengthen low-level
onshore flow. Current marine clouds over the interior will burn
off around mid-afternoon. Expecting greater coverage of marine
clouds and somewhat lower CIGS on Saturday am. Moderate southwest
flow aloft today will become weak northwesterly on Saturday. The
air mass will be stable, with a moist marine lower down low and
dry air above.

Ksea... Stratus burnoff now expected around 21z. Winds will be
light and variable until 21z, then pick up a bit out of the north.

A turn back to light southerly wind is expected late this evening,
in the 05z-07z time frame. More marine clouds on Saturday morning,
with CIGS below 020 expected. Haner

Marine Moderate to strong onshore flow will continue through
the memorial day weekend. This will lead to near gale or gale
force winds over the central and eastern strait of juan de fuca,
mainly during the late afternoon through overnight hours through
this weekend. The strongest onshore flow is expected this evening.

Gale warnings are in effect for the central and eastern strait
during the normal diurnal peak this evening. Haner

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisory until midnight pdt tonight for coastal
waters from point grenville to CAPE shoalwater out 10 nm.

Gale warning until 3 am pdt Saturday for central u.S. Waters
strait of juan de fuca-east entrance u.S. Waters strait of
juan de fuca.

Small craft advisory from 2 pm this afternoon to 3 am pdt
Saturday for admiralty inlet-northern inland waters
including the san juan islands.

Small craft advisory until 9 pm pdt this evening for west
entrance u.S. Waters strait of juan de fuca.
