southeast alaska forecast discussion
national weather service juneau ak
223 pm akdt Tue mar 19 2019

Short term Underneath the sunny skies, record breaking
temperatures are already being reported across the panhandle. As
of writing, klawock is the warmest population center with a
temperature of 70 degrees. The biggest factor in the high temps
this afternoon, is the development of sea breezes. In areas where
sea breezes are unable to develop, record breaking highs are
possible. However, if a sea breeze develops, highs will likely be
limited to the 50s, which is still very warm for this part of the
year. Once the Sun sets this evening expect temperatures to
rapidly cool under the clear skies.

Tomorrow a very weak front will approach the panhandle with
precipitation expected along the outer coast by the late
afternoon or early evening hours. There continues to be variation
in how far south and how far inland the extend of the
precipitation gets, with only a slight chance in the forecast for
the southern panhandle. Also with cloud cover much more prevalent
tomorrow, highs will be unable to reach the magnitude that they
did today.

Thursday's forecast still carries some uncertainty as to how
rapidly the precipitation diminishes over southeast alaska and
how fast the next system pushes north over the gulf. Overall
forecast confidence remains slightly above average through the
short term.

Long term Thursday through Tuesday as of 10 pm Monday
good agreement in operational models and their ensembles that
fairly amplified and negatively tilted mid upper trough will be in
place at the start of the long range south of the aleutians with
strong ridging aloft over western canada. This pattern will
continue to direct a series of storm systems into the central and
northern gulf through the early part of the weekend. Strongest
moisture transport in this type of pattern typically favors the ne
gulf coast and far northern panhandle for periods of heavier
rainfall while the central and southern panhandle would see less
in the way of moisture. Warm temperatures will continue as heights
aloft remain high and there is strong deep layer southerly to
southeast flow in the low levels. Inherited forecast represented
this pattern well so few changes were made.

Beyond the weekend ensemble spread increases quite a bit. There is
some evidence for a general retrogression of the pattern aloft
leading to stronger ridging over the gulf with deep troughing in
the bering sea. This would lead to much drier but still warm
conditions for the panhandle so left the forecast for early next
week trending that way for now.

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.
