.SHORT TERM.../Through Mon night/ Rather quiet morning across the
panhandle with low winds (except for Cross Sound, and Lynn Canal
where winds of 20 kt are blowing this morning), and generally dry
conditions. Scattered low clouds with ceilings of around 2000
feet are present, mainly for the northern and central inner
channels. Petersburg also has some fog this morning with
visibilities down to a 1/2 mile at times.

Main weather stories today are the increasing southerly winds for
today and tonight, and then the incoming front for late Sun night
into Mon. For the southerly winds, those are expected to peak this
evening with 30 kt blowing up Lynn Canal, and gusts to 50 mph
possible at Skagway and on the Klondike Highway. Little has
changed from the previous forecast for winds.

As for the front, there is little in the way of wind associated
with it so it will be more of a precip maker. Still, not a lot of
moisture with it though as its moisture source is in the mid
latitudes rather then the tropics. As a result qpf amounts will
only be around a half an inch total. As for ptype, temps are
expected to be warm (mid 30s or higher) for most areas so rain is
the dominate precip type. Only the Klondike highway will likely
see snow but even then it will only be around 3 to 5 inches total
for tonight through Mon night. Incoming cold air behind the front
Tue night (850 mb temps down to -9 and -10c) is expected to change
any remaining precip to snow but accumulation will be rather
light.

overall forecast confidence is about average.

.LONG TERM.../Tuesday through Saturday/ As of 10pm Saturday. Low
pressure meandering over the NE gulf for the first half of the
extended period will keep showers in the forecast most days.
Upper level CAA wrapping around the low from northern Alaska will
keep the potential for snow going, particularly during the
overnight hours. As the low eventually shifts away SE toward the
end of the week, winds through the inside waters will increase out
of the north and POP should diminish from north to south.

Models have differed from run to run on the strength and track of
the gulf low, and the latest runs are no different. The ECMWF has
been the most consistent and that, along with guidance from WPC
were similar enough to the forecast produced yesterday to only
make minor changes.

Some models are still showing another quick moving low track
across the gulf from the west on Thursday. This would give
another resurgence of moisture to the area before shifting off to
the SE a bit later (Saturday instead of Friday). Opted to
increase POP back up to chance across the northern panhandle on
Thursday to account for this.

Due to model inconsistencies, updates to the extended forecast
were smaller and there is lower forecast confidence overall.
