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 A weak upper level trough will dissipate over western
washington tonight. An upper level ridge will build over the area
Monday and Tuesday. The flow aloft will become southerly midweek--
bringing some moisture up from the south with a chance of showers in
the mountains.

Short term A trough is over the west coast--what is left of it
over western washington is dissipating. Lows will be in the mid 40s
to mid 50s with clouds and some partial clearing. An upper level
ridge will build into the area Monday and Tuesday with warmer temps
and sunshine. Highs Monday will be in the 60s to lower 70s. On
Tuesday highs will range from the mid to upper 60s along the coast
and near the water in the north, to the 70s elsewhere--and maybe
touching 80 in the warmest spots under sunny skies.

Long term There will be a chance of showers around the middle
of the week as the remnants of an upper trough kick out from
california and nevada. Another stronger upper trough could bring a
better chance of showers and cooler temps next weekend. The general
trend of the forecast showing the warmest temps Tuesday and
Wednesday fading through the weekend looks about right--although
a shallow marine push could make Wednesday cooler with a rebound on
Thursday, before falling off again late in the week as the trough
arrives and onshore flow develops.

Aviation An upper level trough axis along the coast will slowly
move inland overnight tonight with northwesterly flow aloft. The air
mass remains generally stable and will gradually dry at the mid and
upper levels... Although marine moisture will remain close to the
surface.

Cigs still a mix ofVFR to MVFR conditions... Although pae remains
the lone station still in ifr conditions. With lifting cigs
elsewhere... Remain hopeful that pae will rebound by late in the
afternoon. As has been the pattern... MVFR conditions expected to
redevelop overnight as continued low level onshore flow brings some
low level marine cloudiness into the interior of western washington.

Ksea...VFR CIGS will persist through the afternoon and into the
evening. MVFR ceilings will likely redevelop after midnight tonight
as stratus pushes into the interior from the coast. Southwest winds
5 to 10 knots this afternoon will make a gradual shift toward the
northwest after 00z this evening. Smr

Marine High pressure offshore and lower pressure east of the
cascades will result in generally weak onshore flow for much of the
forecast period. Small craft advisory westerlies are likely in the
central and eastern strait of juan de fuca during the diurnal peak
late afternoon through early morning hours most days. As has been
the pattern... Inherited headline covers this expectation for tonight
and into Monday morning. Mcdonnal smr

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisory from 3 pm this afternoon to 3 am pdt
Monday for central u.S. Waters strait of juan de fuca-east
entrance u.S. Waters strait of juan de fuca.

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.
