.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3: Today
through Saturday evening)...

Amplified high pressure stretching from the North Pacific over
the majority of interior Alaska continues to bring clear skies and
warm temperatures to Southcentral. Afternoon convection along
elevated terrain will allow for cumulus development each
afternoon and evening into the weekend. The Talkeetna Mountains
and the Copper River Basin remain most favorable for isolated
showers during the evening hours, but coverage should remain
minimal.

Expect afternoon sea breezes for coastal locations and an
elevated Turnagain Arm wind by tomorrow evening as a coastal ridge
builds in. Temperatures will continue to warm through the end of
the work week with temperatures in the 70s expected for many of
the valley / lower- elevation locations, with 60s anticipated
closer to coastline. Increased onshore flow should bring slightly
cooler weather on Saturday, but sunny and comparatively (to the
last several weeks)-warm weather remains on deck for the weekend.

.SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS
(Days 1 through 3)...

Dry conditions will continue across Southwest Alaska through the
end of the week, with exceptions along the Kuskokwim Delta coast,
Nunivak Island, and the Western Capes who will see continued rain
showers through at least tonight.

A new low pushes out of the North Pacific crossing the Aleutian
Chain into the Southern Bering Sea tonight into Friday morning.
Its front brings a reinvigorated round of precipitation to the
Eastern Aleutians and southern Alaska Peninsula as well as a swath
of southerly small craft winds with areas of gales through the
Eastern Aleutians and southern Alaska Peninsula. Small craft to
gale force winds will move north, spreading along the Southwest
coast on Friday. Gusty southerly winds to continue for areas such
as Cold Bay and out of northern gaps and passes of the Alaska
Peninsula.

A Special Weather Statement remains in effect for prolonged
southerly flow into coastal Kuskokwim Delta. Gusty southerly winds
are pushing additional water towards the coast, potentially
raising water levels higher than the normal highest tide line.
This pattern will persist into the early weekend, and as the front
approaches the Southwest coastline on Friday, onshore winds may
increase, decreasing by the late weekend.

.LONG TERM FORECAST (Days 4 through 7: Monday through
Thursday)...

Models are in fairly good agreement with the synoptic setup
through midweek next week with the lowest confidence being toward
the low center over the Bering Sea. High pressure will generally
remain across the mainland of the state. Meanwhile, a closed low
will linger over the Bering Sea and another in the Gulf of Alaska.
A North Pacific low drifting east along the Aleutians towards the
Gulf will merge with the main Gulf low by late Monday. The two
main upper lows over the Alaska waters may phase, keeping
unsettled weather across much of the Gulf of Alaska, Bering Sea,
Aleutians, and the Alaska Peninsula. Strong high pressure will
block any significant movement in the weather pattern for most of
the next week, but embedded shortwave troughs may allow for
smaller, meandering features to resolve with rainfall and
breeziness. Over the mainland, easterly waves emanating from the
Gulf low could mean afternoon showers or thunderstorm development.
Toward midweek, the ridge appears to build further, suppressing
both lows, and leaving warmer and drier conditions more likely for
most of Alaska. While confidence is high with the overall
pattern, confidence is low for the weather associated with finer
features near coastal communities due to slight variations in low
centers.

.AVIATION...

PANC...VFR conditions will prevail. The sea breeze from this
afternoon will likely end by midnight. Gusty, southerly winds
will likely return to the terminal Friday evening, peaking late
Friday night to 15 to 25 kt.
