.SHORT TERM...The ridge which has been responsible for the drier
weather is rapidly decaying, bringing with it an end to the
extended duration of drier weather and clearer skies. A front
approaching the panhandle will stall offshore off the outer
coast by late Thursday, bringing chances of snow showers which
will slowly move into the panhandle through Thursday night and
into Friday. The exception is Yakutat, where the decaying low
associated with the front will bring a much more substantial band
into the Yakutat area, resulting in accumulating snow with totals
reaching 8 to 12 inches. The primary forecast challenge is the
exact placement of the band of snow. If the main band of heavier
precip shifts west, forecasted snowfall totals will be
significantly impacted and much lower.
.LONG TERM...A winter storm warning for Yakutat has been issued
starting Thursday night and continuing through Friday night. Light
snow will continue to taper off into early Saturday for the area.
Elsewhere across the panhandle, outflow conditions will keep the
inner channels relatively windy and cold heading into the weekend,
with enhancement of winds out of east/west channels and valleys.
Saturday there is a potentially complex pattern setting up. The
big picture is that a broad low pressure system will enter the
southern gulf and push a gale force front towards the outer coast.
This broad low will stay offshore and begin to weaken and fill
through the day Saturday and into Sunday. However, a smaller
triple point low is expected to develop further east, closer to
the southern panhandle. Depending on the track of this feature,
northerly outflow winds could be enhanced, preventing any erosion
of the entrenched surface cold pool and allowing for continued
overrunning and thus snow accumulation. This feature would also
serve to enhance the otherwise limited moisture transport over the
panhandle, increasing expected snow totals. With the overall
synoptic flow expected to be out of the SE and parallel to the
outer coast, highest snow totals and precipitation amounts are
expected along the SE portions of Prince of Wales Island as well
as Annette and Ketchikan as of this forecast issuance. With this
pattern, communities further inland will have a harder time seeing
appreciable snow accumulations. For more information on expected
marine conditions for the period, see the marine discussion below.
Stay tuned for further updates as we approach the weekend.
&&
.AVIATION...CIGs continue to be an issue this morning as most places across the
panhandle are seeing ceiling heights vary from MVFR up to VFR
depending on where you are. These low CIGs are expected to continue
through the TAF period. As we head towards the latter half of the
TAF period, the potential for snow increases, especially along the
outer coast. Areas that do develop snow will also see a drop in VIS
during that time. LLWS is also expected to increase as the system
bringing the snow to the area moves closer to the panhandle. But
this is more expected along the outer coast but will need to be
monitored as we head into Friday.
&&
.MARINE...Inner Channels: Outflow and offshore winds strengthen
through the day on Thursday as a front stalls near the outer
coast. Winds will reach strong breeze to near gale strength in
many of the inner channels, with gales Thursday night near Taku
Inlet. Winds will be somewhat lower in Southern Chatham and
Clarence Strait, reaching moderate to fresh breeze.
Outer Coastal Waters: Winds strengthen to gale force in many
areas, with wave heights approaching 20 feet by Thursday night for
the northern outer coastal waters, and 8-10 feet for the far
southern outer coastal waters. Through Friday and into Saturday,
wave heights build significantly in the southern gulf and southern
outer coastal waters, reaching up to 25 ft in some areas.
