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.

southeast alaska forecast discussion
national weather service juneau ak
621 am akdt Fri may 25 2018

Short term through Saturday night ... Friday morning is
beginning with light rain across much of SE alaska ahead of an
occluded front along the outer coast. Rain will continue to
spread inland throughout the day as an upper level wave drifts
eastward across the panhandle. Far southern portions including
prince of wales and ketchikan might catch a break from the wet
weather tonight, but the rain will return Saturday morning.

A broad area of low pressure south of the aleutians will
eventually wrap together and deepen as it moves from the northern
pacific ocean into the central gulf. The gale force front
associated with this system is forecast to be considerably
stronger as it impacts the area Saturday, moving from south to
north. Deeper moisture transport will clip the far southern
panhandle where could see 0.5" to 1.5" of total rainfall.

Model agreement is increasing with the track of Saturday's front,
while the exact placement of the low center is still unclear. Went
with a GFS canadian blend to handle this system, relying mostly
on the GFS for winds over the gulf.

Long term Sunday through Friday as of 10 pm Thursday what a
difference a day makes for the models. Yesterday the ECMWF was the
outlier, today it is the nam. The GFS continues to be the go-to
model. Used a blend of the ECMWF and GFS for Sunday-Tuesday, using
more wpc and ECMWF Wednesday-Friday.

The low coming in over the holiday weekend is still showing a
stronger signature. Increased winds in the gulf about 5 kts
Sunday and Monday, with SCA winds through Sunday night. By Tuesday
night winds should be 15 kt or less across the entire aor.

The 3 day weekend will end wet, but there is drier weather
developing over the area by mid week between systems. Most of the
panhandle will be dry by Wednesday evening as a ridge of high
pressure builds over the area. By Friday evening the ridge will
be weakening and rain will starts moving in along the entire
outer coastal areas and continue to spread inland overnight.

Lowered temperatures again for Sunday-Tuesday a couple of
degrees. Temperatures are still expected to remain in the mid to
upper 50s during the day and range into the 40s overnight. With
less clouds possible with the building ridge, temperatures should rise
a few degrees through mid-late week. Expect to also see a larger
diurnal swing between daytime highs and overnight lows. The other
concern will be fog Wednesday early morning and depending on
clouds and daytime drying, Thursday night could have fog
development as well.

Aviation Marginal vmc today across the panhandle due primarily
to low CIGS and a few locations with diminished vsby. Potential
for gusty winds as the front moves through, but overall am not
expecting winds to be an issue today or this evening. A stronger
front arrives tomorrow morning and this one will produce
turbulence and llws - especially along the outer coast south of
cape fairweather.

Ajk watches warnings advisories
Public... None.

Marine... Small craft advisory for pkz012-036-041>043-051-052.

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.
