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.

224 pm akdt Thu jun 21 2018

Short term Very weak frontal boundary is moving slowly ne
through the eastern gulf early this afternoon. Main mid upper
ridge axis has shifted eastward from its position yesterday and is
now located over western bc.

Weak height falls have spread across the panhandle today and will
continue through this evening. This along with a low level marine
push along the gulf coast and southern panhandle, as well as some
mid level clouds over the interior channels has kept temperatures
10 to 15 degrees cooler than yesterday in some areas. The weak
front offshore will continue to shear apart as it comes inland
this evening, maybe sparking off a few isolated to scattered
showers as it does. Not expecting much in the way of rainfall
though as coverage should be rather sparse.

Surface ridge rebuilds over the gulf on Friday and the low level
flow will turn more w'ly or nw'ly. This will likely keep low
clouds hanging in along the coast. Some stratocumulus likely over
interior areas as well and while an isolated shower can't be ruled
out, lack of deep moisture and any substantial forcing will limit
rain chances.

More significant mid upper trough will move NE into the central
gulf on Saturday. Easterly flow will develop ahead of this system
especially over the central and northern panhandle. Main changes
were to keep things drier through Saturday, then slowly increase
precip chances through Saturday night as weak WAA commences ahead
of the approaching trough and its associated frontal band.

Winds will generally be 15 kt or less through tonight with the
exception of stronger s'ly winds in lynn canal this evening.

Increasing westerly flow Friday will lead to enhanced W to nw
winds in cross sound, clarence strait and around CAPE decision.

Thermal gradient will also lead to SCA conditions once again
Friday afternoon in northern lynn canal. Winds rapidly diminish on
Friday night with light winds continuing into Saturday. Overall
models are in good agreement on the general pattern with the gfs
used for any updates.

Long term Sunday to Thursday a closed lows in an upper
level trough will be moving northeast from the north central
pacific into the southeast gulf of alaska off roughly prince of
wales island or dixon entrance by Sunday afternoon the low weakens
and then move inland by Monday. The upper level flow patter looks
to continues to move in a zonal like pattern though mainly south
of the gulf to the pacific northwest or british columbia coast.

Various models solutions hint ridge over the gulf gulf Monday
night to Tuesday night. They also agree that there will be a
couple of upper level lows over the bering sea to russian far
east, but not exactly where by Tuesday night. The wpc solution
received this morning is a middle of the road solution and quite
usable. Most of the current forecast was close to what the newer
solutions were thinking so only made minimal changes to the
forecast.

Weather should be mainly dry until Saturday evening, when we
should see some rain spread into the panhandle as the low
approaches the southern and should continue into Sunday night, and
possibly taper off later Monday to Tuesday, before a northern
large frontal band starts to moves across the gulf towards the
panhandle on Wednesday.

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.
