What forecasters said that day

The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Anchorage, AK wrote its last area forecast discussion before this gale warning went out at May 19, 5:59 AM AKDT, 9 hours 41 minutes earlier.

Area forecast discussion, May 19, 5:59 AM AKDT, 9 hours 41 minutes before

Southcentral and Southwest Alaska Forecast Discussion...CORRECTED
National Weather Service Anchorage AK
559 AM AKDT Fri May 19 2017

.ANALYSIS AND UPPER LEVELS...

A broad upper level low is centered over Kodiak Island this morning.
There is a dynamic upper level jet streak near 40N south of the
Central Aleutians with a large surface cyclone forming along a warm
front. There is also a weak shortwave ridge moving northeast ahead
of the upper trough. A region of DCVA (Differential Cyclonic
Vorticity Advection) along the leading edge of the trough, in
conjunction with semi-favorable mid-level upper diffluence, is
aiding upper level divergence and ascent over Southcentral. This is
spreading widespread cloudcover inland along with organized shower
activity along the North Gulf Coast and Eastern Kenai Peninsula.
There are also favorable shear profiles aloft for mountain wave
development with satellite imagery capturing an impressive lee-side
cirrus shield moving west off the Kenai/Chugach Mountains. While not
a classic downslope scenario, there is enough of a shadow effect lee
of the Chugach Mountains to keep most inland areas rather dry this
morning. Farther west, the low level flow component is also across
the mighty Western Alaska Range which is helping to keep shower
activity limited to the Bristol Bay region and Alaska Peninsula.

&&

.MODEL DISCUSSION...

The numerical weather models are in excellent agreement through
the short term period (next three days). The largest discrepancies
begin to develop after day 5 as a deep upper level trough carves
itself out over the Bering...ahead of an amplifying NE Pacific
ridge. As always, models struggle with the rapidly amplifying
patterns, so uncertainty quickly increases by late next week
regarding specifics. Otherwise, forecast confidence is high leading
up to that. The GFS and NAM hi-res were favored numerical guidance
owing to consistency and gap winds, respectively.

&&

.AVIATION...
PANC...Predominantly VFR conditions will persist although showers
this morning may briefly drop CIGS below 5000 feet at times. Gusty
southeast winds will increase by this afternoon and persist
through the evening before diminishing again overnight.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Expect another couple of days of cloudy and showery conditions.
The most widespread shower activity will be today as an upper
trough and old decaying front move overhead. Lingering cold air
aloft will promote at least isolated showers inland this afternoon
and evening. The last trough associated with this upper low
pressure moves through late tonight into Saturday, continuing the
light shower threat. While clouds will linger, there will be a
break in precipitation chances on Saturday before a frontal system
enters the Gulf from the east late Saturday night.

With the same lingering synoptic pattern, ridging along the coast,
the favored gap winds will have a diurnal pulsing. Turnagain Arm,
Knik River, and Copper River winds will peak in the afternoon hours
before weakening overnight. Temperatures will be slightly below
normal for this time of year.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA...
The low south of the Alaska Peninsula will slowly make its way
north and settle in over Bristol Bay Friday night. This setup will
keep showers over southwest Alaska until weak high pressure moving
in from the Bering pushes the low off to the southeast Saturday
night. Sunday afternoon and evening will then see more showers due
to afternoon heating in an unstable environment.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS...
Ridging will stay over the western Bering until Saturday when it
begins tracking to the east. This will leave the central and
eastern Bering and Aleutians under weak flow and minimal precip.
The ridge will then make it to the eastern Bering by Sunday but
will also be rapidly diminishing. A front associated with a
Kamchatka low will follow behind the ridging and similarly
dissipate as it moves into the eastern Bering Sunday afternoon.

&&

.LONG TERM FORECAST (Days 3 through 7/Saturday night through
Thursday)... A highly amplified pattern with support from a robust
subtropical jet over the North Pacific will lead to active weather
over the next week. Beginning Saturday night, a short-wave and
surface front lifting northward across the Gulf of Alaska will
spread rain to the north Gulf coast/Prince William Sound region by
Sunday morning, with clouds and showers spreading inland during the
remainder of the day. With deep southerly flow aloft (up the west
side of a western North American ridge) expect abundant moisture
transport leading to moderate to heavy rain along the coast.

Meanwhile, the strong subtropical jet will drive a trough eastward
across the Bering Sea, with the leading edge reaching Southwest
Alaska on Monday. There are some differences in the handling of a
cut-off low out ahead of this as well as with track of individual
short-waves moving through the long-wave trough. This produces a
blurry picture of what may happen over Southwest and Southcentral
Alaska Monday through Tuesday. However, most solutions point
toward a pretty wet scenario, with potential for widespread steady
rain over Southcentral.

As the initial trough exits, medium range solutions are now
trending toward the ECMWF, which has been depicting amplification
along the Aleutians, with a ridge building into Southwest Alaska
Tuesday and Southcentral Alaska Wednesday. If this does verify,
would expect a day of really nice weather. However, the next
trough will quickly follow bringing clouds and rain back into the
forecast.

For the Bering Sea and Aleutians, a continuous supply of short-
waves transiting the upper low/trough will produce unsettled
weather, with occasional rain and wind region-wide.
