southeast alaska forecast discussion
national weather service juneau ak
615 am akst Wed feb 20 2019

Short term Quiet weather Wednesday for southeast alaska as a
high pressure ridge gets moved through the area due to the
developing weather system that will move across the western gulf.

Wednesday night as the developing low moves into the northern
gulf a warm front feature stretch east to the northeast gulf
coast and the the cold front extends south and then southwest. By
early Thursday morning the front will have occluded itself before
the front moves into the panhandle. Think that the temperature
forecast will be the key feature to the upcoming event, right now
have everything just cool enough for much of the weather as snow.

The northern half of the panhandle have been blanked with winter
weather advisories and winter storm warnings, snowfall of the 4 to
6 inches and 6 to 8 inches respectively.

Winds over the inner channels were revised to be lowered through
the lynn canal area to 15 kt. After the low turns southeast
Thursday afternoon and evening, the gradient tightens between the
low near the coast and the higher pressure over the yukon.

Winds should increase to 30 to 35 kt going into Friday morning.

Long term Friday through Wednesday as of 10 pm Tuesday
long range period will be dominated by a big upper ridge or closed
off upper high over the gulf and interior ak. The developing blocking
pattern could last a week or more. There are some model
differences on how far W the ridge axis will develop this weekend
and its evolution next week. Prior to the big ridge building, a
strong shortwave trof will move SE and out of the area during fri,
with a weaker shortwave dropping SE through the area Sat as the
upper ridge to the W begins its amplification. The biggest
difference that result from the model discrepancies is how much
cold air will move into the area during the weekend into early
next week, and how much moderation might occur later on.

Did make some adjustment to pops during the period, moving out the
precip faster Fri into Fri evening, then basically going
completely dry for much of the remaining longer range period. Will
need to watch for some higher level clouds moving in from the N as
shortwave moves through sat, and will also need to monitor
potential for low cloud development later in the weekend and early
next week. This will depend on how warm it gets just above the
sfc, with the GFS warmer in the 925-850 mb layer than the other
models. If the center of the upper ridge high gets close enough,
could see possibility of fog development that becomes persistent
once formed. Did make some temp tweaks, mainly blending in latest
nbm with previous forecast, but also lowered nighttime temps in
some of the usual cold spots even more with decent amount of
snowcover enhancing radiational cooling. Will see some rather
large diurnal temp ranges during next week as Sun angle is high
enough to warm things somewhat during the day. In some places,
would not be surprised if the diurnal range reaches 30 degrees or
more. Forecast confidence is above average for pops, but a bit
below average for temps, clouds, and winds.

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.
