527 am akst Wed jan 23 2019

Short term through Thu night more fog is the main story of
the day, mainly for the southern panhandle, as a ridge builds over
the area. A lack of high level clouds overnight has lead to the
thickening and lowering of low clouds over the southern 2 3rds of
the panhandle with visibilities dropping to a quarter of a mile at
one point. Farther north, a greater concentration of high clouds
have limited fog formation with little to no fog observed north of
icy strait. Fog should dissipate through the day as southerly
flow increases and higher level clouds move in.

For the rest of the short range, a series of fronts will be
moving through the area. The first of which comes Wed afternoon
and night but will mainly affect the northern gulf coast and
northern panhandle as it fights through the surface ridge over the
rest of the area. Front itself is rather weak with mainly light
precip expected and MAX winds only reaching min gale force near
cape suckling with 25 to 30 kt winds elsewhere in the gulf. Main
question with this front is how far north the rain snow line will
be. Many places will be switching to a southerly wind through the
day and even lynn canal is expected to become southerly 25 kt by
this evening. That should be enough to shift the line up lynn
canal so that gustavus, juneau will likely be rain by the time
precip starts. Haines and skagway should warm up as well but may
start out as snow before turning over to rain in the evening. The
higher elevations of the highways will likely stay mostly snow.

Accumulation expected to be light as there is not much moisture
associated with this front.

Two stronger fronts follow the first, one on Thu and the other for
late Thu night. Both will be spreading gale force winds across the
gulf and bringing more precip (this time to most of the panhandle
rather then just the north). By this point most areas will have
been in southerly flow long enough that the precip will be in the
form of rain even up to skagway and haines as snow levels range
around 4000 feet in the south to 1300 feet in the north by thu.

The only areas that may see snow are the higher elevations of the
haines and klondike highways, however snow amounts may be limited
by terrain shadowing with only light accumulations expected at
this time.

Few changes made to the forecast overall, mainly addition of more
fog for the south and refining the timing of the fronts. Main
guidance used was the GFS and nam.

Long term Friday through Tuesday as of 10 pm Monday, the
weekend forecast remains wet with an atmospheric river impacting
the panhandle between Friday and Saturday. While it will be wet
across the panhandle, ensembles continue to point the bulk of the
precipitation at the southern half of the panhandle. Storm total
precipitation ranges between Friday and Saturday afternoon fall
between 2 and 4 inches for the southern panhandle. Strong warm air
advection will accompany this event brining lows well above
freezing for the panhandle this weekend, as high temperatures
push into 40s even over the northern panhandle Friday. Saturday
the system will shift southeast with a north to south drying trend
expected through the day (precipitation will still be heavy
Saturday morning over the southern panhandle).

Seasonable strong high pressure will build behind this system
through Sunday allowing the panhandle to dry. This will also
introduce a chance for foggy conditions over the northern
panhandle Saturday night into Sunday. Then early next week the
next system will push into the gulf, but timing remains
uncertain.

Overall the biggest changes to the forecast were an upward trend
in pop values with 100% values now introduced for portions of
Friday and Saturday. Additionally, temperatures have been trended
upward once again to account for the strong warm air advection on
Friday. Forecast confidence is above average through Sunday and
below average Monday and beyond.

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.
