900 pm pdt Mon may 20 2019

Synopsis An upper level low off the coast will will continue to
bring scattered showers through Tuesday morning. A drier period is
forecast Wednesday and Thursday as a ridge builds, with showers
limited to the mountains. An upper low will bring more showers
Friday and Saturday, with another dry period Sunday and Monday.

Short term tonight through Thursday Persistent showers have
continued this evening and seem likely to last all night. As an
upper level low off the coast moves southeast into oregon, showers
will first move south late tonight, then end by noon Tuesday or so.

High temperatures on Tuesday will be in the 60s.

Wednesday and Thursday look like dry days, except for scattered
afternoon and evening showers in the mountains. Heights will rise a
bit, and under sunny skies high temperatures will rise well into the
70s both days, 60s coast. Burke

Long term Friday through Monday Previous discussion... A ridge
will continue to build into the area on Thursday, again allowing for
mostly dry conditions with the exception being the mountains.

Instability may again warrant the mention of isolated thunder. By
Friday, a subtle shortwave trough will pass through the area from
the north. This will likely allow for increased cloud cover and
perhaps the potential for slightly higher shower coverage-possibly
extending into the lowlands. As this low continues to pull south
into oregon on Saturday it is expected to become closed. This may
lead to continued shower chances through most of the weekend-at
least across the mountains. Ensemble data then argues for another
ridge to build into the area by Monday, which would lead to the
return of drier weather. Have leaned towards this ensemble solution,
as inevitably the deterministic guidance differs noticeably. Kovacik

Aviation Southeasterly flow aloft tonight will become easterly
Tuesday as an upper level low off the coast moves southeast into
oregon. The air mass is moist and slightly unstable with scattered
showers. Expect more showers across the region tonight, with rain
mainly affecting areas from seattle south on Tuesday as the low
slowly exits. Most ceilings areVFR this evening, but with abundant
moisture and light winds, expect pockets of MVFR to ifr conditions
through Tuesday morning. 33 chb
ksea... Showers continue this evening with a possible break early tue
morning. Winds NE 4-8 kt. MVFR ceilings likely after 08z. Chb

Marine Winds are a bit stronger than forecast on the coast, so
increased the forecast there to 10-20 kt over the inner coast, and
15-25 kt with a small craft advisory over the outer coast. A low
well off the columbia river will move southeast into oregon tonight
and Tuesday. After the low moves inland, moderate onshore flow will
develop Tuesday afternoon. This onshore flow pattern will likely
bring advisory level winds to the strait and possibly the coast each
evening. Northwest gales are possible on the coast Friday. Chb

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... Small craft advisory until 5 am pdt Tuesday for coastal waters
from CAPE flattery to james island 10 to 60 nm-coastal
waters from james island to point grenville 10 to 60 nm-
coastal waters from point grenville to CAPE shoalwater 10
to 60 nm.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
