southeast alaska forecast discussion
national weather service juneau ak
252 pm akdt Mon apr 23 2018

Short term A gale force front has made its way over the
panhandle today, before slowly moving off to the southeast. Rain
persisted throughout the panhandle, with some gusty winds in
yakutat, skagway, haines, juneau, and ketchikan salmon landing.

Several shortwaves will follow the front tonight into tomorrow.

The main focus for pressure adjustments was the next system- on
track to reach the northeastern gulf Tuesday night into Wednesday.

Winds will decrease as the front pushes through, followed by a
quick break. Another round of gusty winds concentrated over the
skagway northern lynn area is expected late Tuesday night into
Wednesday as the gradient tightens and the next system moves
southeastward. Wind speeds were blended to the namnest for
adjustments and local increases to marine winds. Pressure changes
were done through a ECMWF gfs blend.

The southern panhandle will dry out, as the main frontal band
pushes northeastward. Temperatures were mainly warmed over the
southern panhandle (using MOS guidance), as the precip pushes
through. Patchy fog may become a concern in the area encompassing
clarence strait to southern chatham tomorrow night with light
winds and some breaks in the clouds. Pop and QPF were both nudged
towards the gfs.

By Wednesday morning, greater model differences exist, but
agreement does well with individual shortwaves today and tomorrow.

Long term Wednesday through Monday as of 10 pm Sunday
made minimal change to long range forecast as it still looked
reasonable. Did make a slight eastward adjustment to pops for
wed- Thu as models suggested the precip would get further e.

Remaining parameters were left as is.

Wed and Wed night still look wet over the NW half of the area with
front just offshore. Then as front pushes inland and weakens,
should dry out during thu. There are some model differences on how
fast the precip diminishes thu, so later shifts may need to
adjust that some.

Still looks like some ridging will take over for Fri into the
weekend, but models differ on how strong the ridge will be and
whether any systems will get into the area. Kept pops on the low
side for now for that time frame.

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.
