Aviation 27 00z TAF cycle... A surge of south winds and
ifr lifr fog has moved up the coast and coastal waters up to lane
county. This low stratus and fog will remain in the coastal waters
and move inland at the coast this evening, remaining through the
early morning.

All other areas will remainVFR through the TAF period with some
fair weather cumulus building tomorrow afternoon -sven schaaf

Prev discussion issued 320 pm pdt Fri may 26 2017
short term... Through Monday... Fog and stratus hovering along and
near the coast will be with us through the weekend as high
pressure builds over the area. Temperatures will warm through the
weekend from near normal values to 10 to 15 degrees above normal
Sunday into Monday. Be advised that area waterways, especially
rivers, are still quite cold this time of the year.

By Sunday there will be lots of instability, but moisture
sufficient for showers and thunderstorms will be limited.

However, there will be a slight possibility of a few weak
instability type of thunderstorms over portions of the cascades
and siskiyous due to local additional moisture and heat sources.

On Monday the combinations of diffluence aloft and flow
accelerating over the area due to an approaching slightly
negatively tilted upper level trough will combine with
instability and moisture to result in a possibility of showers and
thunderstorms across much of the area, centered on the cascades
and siskiyous. Persisting south-southeast flow of 15 knots or
greater over the siskiyous Sunday through Tuesday means that there
is a real threat for thunderstorms west of the cascades in oregon
Monday into Tuesday. Precipitable water values reach 0.80" to
1.10" late Monday afternoon. So, keep an eye to the sky Sunday and
especially Monday, and be prepared to take shelter in areas where
thunderstorms are in the forecast Monday afternoon and evening.

Instability parameters indicate that some of the storms could be
strong, and an isolated severe storm is possible. Btl
long term... Tuesday through Friday. The extended period begins
active with southerly low level flow continuing to feed unstable
air into the region. The GFS is indicating li's of
-4 over SW jackson SE josephine counties and -7 over the crater
lake area. In addition to the very unstable air mass and strong
conversion in the siskiyous and cascades with the southerly flow
meeting the afternoon upvalley flow a strong vort axis is also
indicated to move through shortly after MAX heating. Starting
Wednesday the GFS and ec veer apart with the GFS closing an upper
low and bringing it south into southern ca, and the ec indication
an open trough. With this I do not have high confidence in
convection on Thursday as the ec is indicating a weak ridge
building over the region. -sven
marine... .Updated 200 pm Friday 26 may 2017... No marine headlines
are currently in effect with a period of lighter winds and
lessening seas expected tonight that will continue through at
least Sunday. Seas right now are 6 to 8 feet at 10 seconds and
will lower to 4 to 6 feet by Saturday morning. The main weather
impact over the coastal waters this weekend will be the marine
layer stratus fog. Marine stratus eroded from the north in the
northern outer waters (beyond 10 nm from shore north of cape
blanco) this afternoon, where skies are currently clear. However,
the deep marine layer persists along the coast and farther south
where marine stratus and areas of fog are expected to continue
most of the weekend. A weak thermal trough will develop redevelop
Sunday night into Monday, but north winds will probably remain
below small craft advisory levels through Tuesday. Small craft
advisory level winds and seas are possible south of CAPE blanco
mid-late next week. -spilde
fire weather...

a chance of thunderstorms is expected the afternoon and evening of
memorial day across the area following a period of warm and dry
weather. While most of the thunderstorms are currently expected
along, south, and east of the cascades and siskiyous, moderate
southeast flow across the area means that some areas west of the
cascades could also be affected. The threat is expected to
continue into Tuesday. Btl

Mfr watches warnings advisories
Or... None.

Ca... None.

Pacific coastal waters... None.

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.
