southeast alaska forecast discussion

250 pm akdt Wed may 22 2019

Short term Temperatures are pushing into the upper 60s once
again across the interior portions of the panhandle under sunny
skies. However, a quick pattern change will occur overnight as a
front over the central gulf pushes inland overnight. Precipitation
is more likely over the northern half of the panhandle, but
rainfall amounts will be low from this system. Conditions will dry
through the afternoon and evening hours of Thursday with some
post frontal shower activity likely persisting along the coast
into the early morning hours of Friday. The strongest winds will
be over the northern inner channels, but they are expected to stay
below small craft levels. Behind the system surface ridging looks
to rebuild Friday which will allow temperatures to recover into
the mid 50s and low 60s, especially, as skies clear during the
afternoon hours.

Significant changes were not needed in the short term. Pop was
increased along the northeast gulf coast and northern inner
channels late tonight and Friday morning, but QPF was kept low.

Overall forecast confidence is above average.

Long term Friday through Wednesday as of 10 pm Tuesday
upper ridge will build nne across the area fri-sat night. The
ridge should drift just E of the area by mon. Models diverge to
some degree on features after sun, but it does look like a
weakening occluded front will try to move into the area for
sun-mon. After that, operational model agreement is poor so
confidence in any one solution is low. Ensemble means between the
gfs and ECMWF are close on the large scale, suggesting that the
ridge will still be around just to the E of the area into
midweek. Decided to blend in latest wpc to handle things for the
most part from Sat onward.

Made mostly minor adjustments to the forecast. Put in a bit more
cloud cover to start on Fri with elongated upper shortwave moving
through and a w-nw low level flow. Appears that clouds will
decrease, especially over the inner channels, during the day fri
once upper shortwave moves past the area and allows a sharper nw
flow to develop. Tweaked temps downward some Fri as it will take
some time for the lower levels to respond to the warming aloft due
to some cloud cover early in the day. Does appear that Sat will be
a warmer day, but there is some model disagreement on how much
warmer it will get as they differ on how much the sub 850 mb
layer will warm. Also, slowed the eastward movement of pops sat
into Sun with ridging holding things off to the W more initially.

Think lowest pops sun-tue will be across the SE part of the area
given proximity of upper ridge to them.

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.
