830 am pdt Mon mar 25 2019

Synopsis A weakening front will move through the area from the
south this afternoon and evening. Post frontal showers will end
on Tuesday. Low level flow will become offshore as the next system
moves inland south of the area Tuesday night and Wednesday. An
upper level low off the oregon coast Thursday will dissipate
Friday. The next system will arrive late next weekend.

Short term today through Wednesday A front will spread areas
of light rain into the area from the south this afternoon and
evening with rain changing to spotty showers in the evening as
the front exits north. Isolated to scattered showers will linger
behind the front into Tuesday, especially over the mountains.

Showers should end entirely Tuesday evening as weak high pressure
aloft moves overhead. Most of the area is looking dry on Wednesday
as well. An area of diffluence downstream of an upper low off the
oregon coast will bring a threat of rain for areas south of
seattle later Wednesday. Temperatures will be near normal through
the period. Schneider

Long term Thursday through Sunday Previous
discussion... Extended solutions have a hard time coming up with a
consistent solution for the upper level low on Thursday with the
gfs moving the low to the northeast while the ECMWF has the low
barely moving east. Both solutions have the low close enough to
keep at least a chance of showers in the forecast. Shower activity
will be more widespread if the GFS solution is correct.

Model inconsistencies continue on Friday with the ECMWF weakening
the low and moving it inland over southern oregon while the gfs
has what is left of the low near astoria by Friday afternoon. With
the inconsistent solutions will have to stay with a broad brush
chance of showers on Friday. Both models have some upper level
ridging on Saturday for a dry day followed by a front sometime on
Sunday. High temperatures will remain near normal, mid 50s to
lower 60s. Lows will be in the mid 30s to mid 40s through the
period. Felton

Aviation Next frontal system arrives today in association with
large scale troughing located over the pacific with southerly flow
aloft. High clouds through the morning with mid level clouds by
afternoon as clouds lower in approach of the front. The air mass
will become moist and unstable as rain will spread across the area
from SW to NE late this afternoon into this evening. Rain will
become showery in nature overnight into Tuesday generally through
15z. Expect ceilings to beVFR through the evening with MVFR
possible tonight into early Tuesday. Winds will also be breezy as
the front pushes through. Southerly winds will generally be
sustained 10-15 kts with gusts near 20 kts possible.

Ksea...VFR conditions expected through this evening with high clouds
around. Rain spreads into the region later this afternoon into this
evening. Rain chances generally between 23z-04z becoming spotty in
nature. MVFR possible overnight into Tuesday following the front.

Light N NE winds this morning will become southerly later this
afternoon, following 23z, with sustained southerly 10-15 kts, gusts
near 20 kts possible. Jd

Marine Weak offshore flow through this morning will gradually
turn offshore during this afternoon as an area of low pressure moves
closer to western washington. Small craft winds will continue
through the strait and along the coastal waters. Winds will
transition to southerly this afternoon and increase as the frontal
system pushes through. Small craft winds are likely from the
interior waters and eastern strait, as well as the coastal waters by
late this afternoon. Winds will gradually ease through Tuesday.

Winds will likely turn offshore Tuesday night with a low pressure
system spinning well of the oregon coast. Jd

Hydrology River flooding is not expected for the next 7 days.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
