Metlakatla, AK

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.

Short term Surface ridge continues to build over the gulf this
afternoon. Weak mid level wave with almost no surface reflection
will track through the panhandle tonight, bringing no more than
an increase in the mid to high clouds. Low level stratus and
stratocumulus has held tough in a few areas this afternoon but
many areas did see some breaks. Southerly winds have been elevated
a bit in lynn canal so included a SCA through early evening for
northern lynn where 20 to 25 kt southerlies will persist for a few
more hours.

Strengthening baroclinic wave seen on WV and IR this afternoon
over the npac south of 50n will drift north into the southern gulf
on Saturday. The low will weaken through Sunday and begin to slide
off to the east towards haida gwaii by Sunday night. Saturday
should be a fairly nice day most areas. Generally partly to
mostly cloudy conditions with some more breaks than today especially
over the north. Winds will be light as the southerly and westerly
pressure gradients collapse with the approach of the low to the
south.

Weakening warm frontal band will graze the outer coast Saturday
evening, most likely producing little more than a few sprinkles or
more likely an increase in clouds. A second weakening frontal band
will move onshore the southern panhandle late Saturday night and
likely fall apart as it comes north through the panhandle on
Sunday. Some rain is likely with this feature but amounts won't be
too significant. Scattered showers will likely continue in the
post frontal environment Sunday evening over the southern
panhandle as the mid levels cool with the approach of the upper
low. Winds will generally be 15 kt or less over the inside waters
with the exception of stronger 20 kt southerlies in clarence
strait Sunday and the typical afternoon southerlies in northern
lynn canal.

Long term Monday through Friday ... A mid-upper trough with a
closed low over the southeastern gulf will drift east Sunday. The
surface low weakens as it moves inland over haida gwaii by Monday
morning. Brisk southerly winds will be enhanced over the southern
panhandle especially into clarence strait Sunday morning through
Sunday night, but wind speeds should remain below SCA conditions.

A frontal precip band will also lift into the southern and central
panhandle Sunday morning, spreading northward as it diminishes
throughout the day.

The upper level flow pattern then looks to set up with weak
ridging over the gulf Monday and Tuesday, leading to more zonal
westerly flow over the eastern gulf Monday afternoon through
Tuesday. Most of the models are also suggesting an upper low near
the aleutians will set up a front in the western gulf by
Wednesday, which will move across the gulf towards the panhandle.

Overall the pattern for later in the week looks to be cloudy and
increasing chances of rain into Thursday and Friday.

Most of the operational models again have similar idea to what the
wpc solution has. Much of the current forecast continued inline
with the new wpc solution and only needed minimal changes.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
