southeast alaska forecast discussion
national weather service juneau ak
206 pm akdt Wed sep 19 2018

Short term Wednesday to Friday clear and dry remains the
general description for the eastern gulf and southeast alaska. A
ridge axis over the north pacific is tipping the northern edge
across the gulf. One stream of moisture with a short wave aloft
south of the gulf of alaska will be tracking eastward toward
northern vancouver island. Further west will be the system we are
watching that will be causing weather is approaching the western
aleutians Wednesday evening. That system is not expected until
the weekend in the panhandle.

Winds not expected to be that strong again in the forecast area
with winds mainly under 20 kt for the outer waters and the inner
waters. With a general light offshore flow in the north and lighter
westerly in the southern sections seas generally 5 ft or less
across the gulf.

Have reissued a frost advisory for the yakutat, kake and
petersburg areas again for tonight as it looks like those areas
may cool down to 30 to 34 degrees with light winds.

Local patchy fog may form near tidal flats and areas of lighter
winds towards morning. Forecast confidence is above average.

Long term Friday through Tuesday ... Confidence is increasing
for a change in the weather pattern within the extended forecast
as rain is looking more likely to return to SE alaska later this
weekend. An upper level ridge will slowly shift eastward into the
gulf, pushing an upper trough into the western us canada by
Saturday. A strong jet over the top of the ridge will help drive a
weather front across the gulf Saturday bringing rain to the ne
gulf coast and at least into the n'rn panhandle Saturday night.

The general upper level pattern of a trough in the bering sea and
a ridge over the gulf is progged to persist into early next week,
but model details really begin diverging Sunday onward. Better
agreement among the models though has allowed thinking of a return
to a more seasonably wet pattern to be possible. Operational
models along with wpc guidance was consulted to nudge pop in an
upward trend starting Saturday evening through mid-week.

Friday may be the last full day of dry weather and above normal
temperatures across the panhandle. A shortwave feature may try to
sneak in ahead of the ridge Friday night over the panhandle, but
likely only to increase cloud cover. More zonal, onshore flow sets
up over the gulf Saturday likely to persist through the long term
period. Forecaster confidence is average through the weekend.

Aviation No significant hazards pertaining to aviation
expected tonight and Thursday at this time.

Ajk watches warnings advisories
Public... Frost advisory from 1 am to 9 am akdt Thursday for akz017-026.

Marine... None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
