.SHORT TERM...Satellite imagery reveals that the low south of
Haida Gwaii is STILL there. Surface progs are finally washing it
out, but upper level charts maintain a closed circulation through
the duration of the short range forecast period as is moves slowly
to the east and the British Columbia coastline, then northeast
and finally out of the area. Afternoon thunderstorm activity is
beginning as of early this afternoon from Central British Columbia
north to the Yukon. Easterly wave activity is carrying these
cells to the west and all seems on track for a slight chance of
thunderstorms on the U.S. side of the international border near
Taku Inlet, the far northern inner channels, and northern Lynn
Canal. After this evening, thunderstorm potential diminishes
pretty much all together as a ridge shifts east and pushes a
slightly more stable airmass over the Panhandle. Ridging will be
short lived as a front moves in from the west across the central
Gulf on Wednesday. Precipitation from this front is not expected
to arrive along the outer coast until Thursday, with showers
remaining in the forecast until then. Once the frontal
precipitation arrives, it will remain with us through the
remainder of this short range forecast period.

The brief period of ridging at the surface will act in conjunction
with lower pressure over the Yukon to create small craft
southerlies over northern Lynn Canal on Wednesday. Beyond then,
small craft winds associated with the approaching front will
spread west to east across the Gulf through Wednesday night.
East Gulf winds will peak late in the day Thursday with
southeasterlies up to 30 kts from offshore Cape Decision to Cape
Fairweather and again from Icy Bay west to Cape Suckling.

Clear skies over the central Panhandle today allowed some
locations to reach near 70 degrees, which is above normal for late
July. The situation will change tomorrow when increased cloudiness
will result in highs for the day from the upper 50s to lower 60s.
Overnight lows, however, will continue to trend slightly above
normal in the low to mid 50s due to the cloud cover.

.LONG TERM.../Thursday through Tuesday as of 10 PM Monday/...A
front moves into the Panhandle on Thursday, bringing increased
cloudiness, marginally cooler temperatures, and decent chances of
rain for the southern 3/4 of the Panhandle. The rain will become more
periodic in nature by the latter half of the weekend. The rain
looks to pick up again by Tuesday of next week for the southern
Panhandle as the same surface low that will have been meandering
and weakening in the southeastern Gulf that brought the front into
southeast Alaska approaches the southern Panhandle from the
southwest. By Wednesday of next week, that low looks like it will
continue to weaken into a wave and move ashore somewhere in the
southern Panhandle / Dixon Entrance area. There appears to be some
enhancement in IVT values with the approaching front, but nothing
that appears to be particularly impactful in terms of an
atmospheric river, so far.

The surface ridge that will have built in and sharpened over the
Panhandle looks to remain in place to a varying degree of
strength through the entire long term forecast period, helping to
bring general onshore flow and chances for showers to areas
outside of the primary influence of any nearby lows or fronts
through the period.

Winds of up to 30 knots are possible along the outer coast and
around the Dixon Entrance as the front approaches the Panhandle
around the Thursday timeframe of this week. Waves up to 11 ft are
possible along the outer coast with the strongest winds as the
front approaches the Panhandle. Winds look to remain relatively
light at around 15 knots or less for the majority of the Inner
Channels and Panhandle.

High temperatures look to remain mild across the Panhandle with
the highest values of the upper 60s to lower 70s across the
extreme northeastern Panhandle around the Skagway / Northern Lynn
Canal area. Recent model guidance and temperatures aloft at 850mb
appear to support this. That area has the lowest chances for
precipitation, highest chances for some breaks in the clouds through
the period. Generally, the farther south you go through the long
term forecast period, the higher the chances will be for cloudier
skies, rainfall, and more moderated/cooler surface temperatures.

Forecast confidence is around average for the long term as model
agreement was reasonable, but not perfect as there was some
divergence between the models on the location and strength of the
aforementioned surface low pressure center as time progresses
through the forecast period.
