southeast alaska forecast discussion
national weather service juneau ak
607 am akdt Fri mar 24 2017

Short term A low pressure system moving northward toward hecate
strait will be the main weather maker over the next 24hrs. Rain
began in ketchikan just after midnight and is slowly spreading
north this morning. Expect the rain to reach port alexander and
petersburg in the next couple hours but not quite get to juneau
by late afternoon. Some mixing is possible this morning, but no
accumulation is expected as this system is bringing in warmer air
from the south.

The low is progged to move NE across the southern panhandle and
into canada late tonight. Meanwhile an upper level trough will
move west across the gulf. This looks to take over as the main
driving force and will also keep most of the energy south of
juneau tonight. As the surface low moves ne, the area of clouds
and precip will shift to be more along the coastal mountains,
leaving the NE gulf coast out of precip chances. Think that
offshore flow at the lower levels from juneau north to
haines/skagway will limit rain/snow amounts with this system.

Therefore, have lowered pop and QPF for those areas.

Preferred the NAM for updates to this forecast package. Forecaster
confidence is above average.

Long term Models continue to indicate active upper level
pattern persisting through mid next week before a brief break late
next week.

This period begins with one shortwave moving inland resulting in
diminishing precip chances Sat night into sun. Persistent upper
low over the N gulf will maintain deep swly flow across the
region.

Precip chances will increase heading into Mon as another, near
gale, low moves into the SE gulf. This low will also bring
advisory level winds to the coastal waters and inner channels.

Ptype remains a challenge but maintained current forecast of
mainly ra for southern panhandle, sn/rasn over the central
panhandle in the overnight/morning before becoming all ra in the
afternoon and sn over the northern panhandle.

Model solutions and ensembles begin to diverge early next week but
maintain the active pattern through at least mid week as temps
moderate to near normal. This means continued mixed precip
overnight/liquid precip during afternoons for most of the panhandle.

Despite the divergent model/ensemble solutions, a period of dry
weather expected late next week as a short wave ridge amplifies
ahead of a low moving into the western gulf. Drier weather will be
brief as this low will result in deeper and longer SW flow to se
ak heading into next weekend.

Ajk watches/warnings/advisories
Public... None.

Marine... Small craft advisory for pkz012-041.

Small craft advisory due to seas for pkz042.

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.
