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.

301 am pdt Thu may 24 2018

Discussion Current observations are showing a few showers in
the foothills of eastern douglas county and maybe a stray shower
along highway 140 on the crest of the cascades. These showers are
expected to linger for a couple more hours before a brief lull can
occur later this morning. This activity is due in part to a low
pressure system moving inland off the coast of san francisco.

As a result, high resolution models are showing an uptick in the
activity beginning on the east side again as early as 11:00 am,
and that's where most of the activity will begin tomorrow morning.

Today will be quite similar to yesterday, with isolated to
scattered thunderstorms over most of the area, with the highest
concentration occurring over the terrain. An isolated thunderstorm
could be possible west of the cascades, but will generally east of
grants pass. Thunderstorms today are not expected to become
severe, but could create occasional to frequent lightning strikes
and gusty winds up to 40 mph.

The showers will continue overnight with the thunderstorm threat
largely dissipating after sunset. A stray lightning strike will be
possible along the cascades and east. For Friday, CAPE values and
lifted indices seem a little weaker than for today, and will
concentrate the thunderstorm potential over the cascades,
siskiyous and to the east and south. That being said, Friday
appears to be trending wetter than yesterday or today. Once the
thunderstorm threat largely ends after sunset on Saturday, showers
will gradually decrease from west to east as the low moves
eastward into nevada.

A ridge will build in behind the system over the weekend, and
skies are generally expected to clear with the exception of the
marine layer over the coast and spilling into the umpqua basin.

Temperatures will be cooler on Friday and Saturday before
rebounding on Sunday and Monday.

This pattern is expected to continue for most of the week, but
another trough will likely begin to dig in from the north. With
moisture pooling over northern california, this system will likely
be mostly dry for oregon, but bring another round of shower and
thunderstorm chances for northern california in the extended
forecast. -schaaf

Aviation 24 12z... The marine layer has deepened, and
conditions at the coast and the western half of the umpqua basin
are generally MVFR and should stay MVFR through Thursday morning.

Gradual improvement after around 16z should allow some coastal
areas to briefly break out toVFR in the afternoon.

Farther inland, generally east of the line from the illinois
valley to roseburg, showers will gradually diminish overnight into
Thursday morning. Scattered thunderstorms are expected in the
same region on Thursday afternoon and evening. -schaaf dw

Marine Updated 230 am pdt Thursday 24 may 2018... Light
northerly winds today will increase tonight and Friday. Small
craft advisory level winds and steep seas are expected beginning
tonight and continuing on Friday for areas south of CAPE blanco.

Winds will weaken Friday night then increase late Saturday into
Sunday as a thermal trough develops along the coast. North winds
will strengthen further Sunday evening into early next week with
small craft advisory conditions expected over most the waters and
gales and very steep wind-driven seas possible for areas south of
cape blanco. -cc

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.
