Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
525 PM AKDT Mon May 10 2021

.ANALYSIS AND UPPER LEVELS...

A series of upper lows is bringing widespread low cloud cover
across much of the Bering/Aleutians, with scattered showers seen
over the eastern Aleutians near a weak surface low. Farther
east, southeasterly flow aloft is bringing light rain to the Gulf
coast. Much of the interior remains dry. Steady rain is also
observed over Kodiak Island with a long fetch of moisture
extending across the Gulf and along the Panhandle as shown in the
latest water vapor imagery.

&&

.MODEL DISCUSSION...

Models are in good large scale agreement. A compact low will
approach Prince William Sound Tuesday morning. The GFS takes a
slightly more southerly track, which would lead to stronger winds
in the Sound itself, while the NAM moves directly over the Sound
and therefore winds would be weaker. Although showers near higher
terrain are possible in the coming days, models are overestimating
the QPF and thus any shower activity would be light.

&&

.AVIATION...

PANC...Southeasterly winds are expected to increase this
afternoon, with gusts potentially approaching 30 kts. These will
gradually diminish though this evening. VFR conditions will
persist, though ceilings may briefly fall below 5000' this
evening.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...

A midlevel shortwave and surface low over the central Gulf this
evening is expected to move into the Prince William Sound Tuesday
afternoon. Another upper level wave currently over the AKPen will
get pulled into the Gulf by the aforementioned low, where the two
will then merge before moving into Southeast Alaska Wednesday
afternoon. This pattern will continue what Southcentral observed
over the weekend, with rain likely along the coast and a few
showers possible over the downslope regions from Homer north to
Palmer. The main difference will be a weak easterly wave to the
north of the upper level low center providing lift for rain over
the interior mountain ranges. This will begin over the Wrangells
tonight and move east into the Talkeetna Mountains and Western
Alaska Range Tuesday afternoon. As for the interior valleys, there
is a chance of rain along the Richardson Highway over and north
of Glennallen Tuesday afternoon. The same upper level wave is then
expected to swing into the Susitna Valley later on Tuesday with
rain likely to the north of Talkeetna.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3: Monday
afternoon through Thursday)...

Low pressure over the Bering and AKPEN will keep a chance of
showers through Tuesday, however coverage of showers will decrease
tonight and Tuesday. On Wednesday, high pressure will try to edge
in from the interior. This will cause some patchy fog to form
over the valleys Wednesday morning. However, a few mainly
afternoon showers will develop mostly over the higher terrain but
may drift over valley locations. On Thursday an approaching
occluded front will increase clouds with a chance of showers by
late in the day. Temperatures will warm slightly Wednesday and
Thursday into the 50s for highs which will be near or slightly
above normal for this part of May.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3: Monday
afternoon through Thursday)...

An elongated area of low pressure with several low centers will
affect the Bering and Aleutians. A weakening low near the
Pribilofs will dissipate tonight causing a few showers. While a
low near the Kamchatka Peninsula will move across the northern
Bering keeping unsettled weather across the western and northern
Bering. On Tuesday a frontal system will move into the Western
Aleutians with winds near 25 knots and areas of rain. This front
will move east Wednesday and Thursday across the Bering spreading
rain with winds up to 30 knots. The parent low of the
aforementioned front will move over the Western Aleutians
Wednesday and Thursday and slowly move east, but will have very
limited impacts other than rain. By Thursday a low over the North
Pacific will interact with the front moving near the Eastern
Aleutians and AKPEN. This will cause gale force winds near the
AKPEN into Bristol Bay and the eastern Bering with moderate to
heavy rain possible.

&&

.MARINE (Days 3 through 5: Thursday through Saturday)...

Bering: A broad complex low will be in place over the Bering
through Saturday. Southeasterly gale force winds are likely across
the eastern Bering on Thursday. Westerly gales are likely just
south of the Aleutian chain Friday as the low center moves into
the eastern Bering for Saturday.

Gulf of Alaska: There is increasing confidence a gale force front
will enter the western Bering Thursday morning. Gusty southeasterly
winds are likely through the usual places including the Barren
Islands, Shelikof Strait, and Kamishak Bay Thursday into Friday.
Gusty conditions are expected to taper by Saturday as the front
lifts inland.

&&

.Long Term Forecast (Days 4 through 7: Friday through Monday)...

The key feature in the long term is a broad upper level low
centered over the Bering with several upper level waves lifting
inland. This will keep a generally unsettled pattern across the
southern half of the state through the weekend. The leading front
associated with this large low will lift inland over Southcentral
Friday into Saturday. As the low center continues to drift over
the Eastern Aleutians late Saturday, rain and gusty winds can be
expected across much of the chain and the southern Alaska
Peninsula. Showers will also spread across Southwest through
Sunday afternoon as the low tracks into the Gulf for the early
part of next week. In the wake of the low, conditions will improve
over the Bering as a ridge of high pressure builds early Monday.
Cloud cover and scattered showers may remain across Southcentral
through Monday as residual upper level waves propagate inland.
