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 An onshore flow pattern will prevail for the next
several days for night and morning clouds and partial afternoon
sunshine most days. An upper trough could bring some showers
around the middle of next week.

Short term An upper trough will move over the area Friday but
it looks dry. Low level onshore flow will continue for night and
morning clouds and partial afternoon sunshine. Highs will be near
normal. More of the same is expected for Saturday and Sunday with
low level onshore flow continuing. A weak upper short wave could
bring some drizzle Saturday morning. Temperatures will be near
normal Friday and Saturday. Rising upper heights and slightly
weaker onshore flow will allow highs to warm a few degrees on
Sunday. Schneider

Long term An upper trough will gradually settle over the area
for the first half of next week with low level onshore flow
continuing. There are no fronts or organized weather systems
expected but there will be slight chance of showers Tuesday and
beyond. By Thursday the models become quite inconsistent adding to
the uncertainty and justifying low chance pops for now. Schneider

Aviation Tail end of a weak upper level trough will brush by
western washington late Friday. Moderate southwest flow aloft,
becoming westerly on Friday evening. Low-level onshore flow will
keep advecting a moist marine layer onshore, with dry and stable
air above. Marine clouds will fill back into the lowlands late
tonight, burning off again around mid-day Friday.

Ksea... A light north wind will slowly develop over the next few
hours, but it will likely take until after about 04z for it to get
as strong as 6 kt. Once northerly wind develops, a northerly
component should continue into Friday evening. Cloudwise, late
tonight and Friday morning, a higher deck of marine clouds will
affect the terminal, with CIGS mainly between 025 and 030. Should
have no trouble burning off the marine clouds by mid-day Friday.

Haner

Marine Varying degrees of moderate to strong onshore gradients
and westerly flow will continue through the memorial day weekend
and into early next week. Forecasting high-end small craft
advisory strength westerlies through the strait this evening,
though gales are still possible. On Friday evening, uil-bli
gradient should peak around +3.5 to +4.0 mb, so forecasting
westerly gales through the strait Friday evening. High-end small
craft winds are expected during the late afternoon and evening
each day this weekend, though gales are certainly possible on just
about any evening. Haner

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.
