southeast alaska forecast discussion
national weather service juneau ak
559 am akst Fri feb 23 2018

Short term Friday morning through Saturday night ... As one
low exits, our focus has shifted toward a second gale force low in
the gulf on Saturday.

Showery precipitation has taken over across the central panhandle
this morning. Yakutat received 7 inches of snow over the last 24
hours and petersburg reported just over 5 inches as of early this
morning. Many locations have already changed over to rain or a
rain snow mix as pockets of warm air advection have moved in
behind the low, limiting snow accumulations to less than 1 inch at
the juneau airport. Winter storm warnings for both zones were
cancelled early as a result of the warmer than anticipated low
level air and a lack of heavy snow.

Changes to winds on the outside were confined to the Saturday
and Saturday night time period with a strong nudge towards the
06z nam. Net result was increased winds to high end gales over
the gulf. Cannot rule out storm force winds at this time.

Temperatures agreed quite well in both MOS guidance and model
spectrum spreads. Maximum temperatures over the coastal waters
were decreased for today and a slight decrease in temperatures for
most locations for Saturday. Not many changes to minimum
temperatures were made, as some clearing is expected tonight
before the next system moves in.

Pop and QPF were adjusted using the NAM and 3 hour gfs, as
agreement between these two models was relatively consistent once
again. This quickened the onset of precipitation to mid-morning
Saturday and ending late Saturday night for most of the panhandle.

Preliminary snowfall totals for Saturday are ranging from 1-2",
with the outer coast likely to see rain. This will shift us into
more of a showery regime, with CAPE values approaching 400-500
j kg. A possibility of lightning along the coast cannot be ruled
out completely.

Confidence remains about average. The general pattern has not
changed significantly overall, but it is the small scale
variations in these patterns that have limited the predictability
of these systems.

Long term Sunday through Friday... We'll start off the long term
on Sunday with a broad upper level trough positioned over the
panhandle and western canada and an upper level ridge building
over the western gulf. A weakening surface low associated with a
shortwave embedded within the upper level trough will continue to
traverse southeast across the panhandle, taking with it lingering
precipitation. This feature will also help to tighten the
pressure gradient between it and a weak high pressure near the
border with mainland alaska and the yukon. This setup may provide
a brief northerly outflow event, so we increased winds
accordingly through lynn canal. As the ridge of high pressure
strengthens over the gulf and pushes east Sunday night into early
Monday morning, this should help to fully clear out precipitation,
albeit briefly, before our next system moves in Monday.

Continuing with our progressive pattern trend, a shortwave with
an associated developing surface low will dig into the western
gulf Sunday night. A weather front with the low will lift across
the eastern gulf and impact the panhandle Monday continuing into
Tuesday. 700 mb model frontogenesis shows strengthening along the
front, which should help trigger the lift we need for
precipitation. Models also show significant moisture advection
ahead of the front on Monday, so we could see some substantial
precip amounts with this system. This may potentially be a tricky
system regarding precip type; model 925 mb temps show a relatively
cold air mass over the panhandle, so precip could start off as
snow and briefly transition to a rain snow mix or remain all snow.

We mainly focused on forecast updates for the early period in the
long term, which included the Sunday through Monday timeframe. We
chose a NAM gem blend, using NAM more for winds and gem for
precip elements. After this timeframe, we allowed wpc guidance to
remain and added in nbm for select elements, mainly temperatures,
which were adjusted down for later next week.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
