Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
407 PM AKDT Tue Jun 10 2025

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

A high pressure ridge pushing in over Southcentral Alaska is set
to bring some of the nicest weather we have seen so far this
summer! Skies will continue to clear as a low pressure system in
the Gulf of Alaska pushes south. Temperatures will steadily rise
over the next couple days with highs in the upper 60`s to low 70`s
by Thursday. Afternoon and evening showers may develop on the
slopes of the Talkeetna Mountains while shortwave perturbations
being spun up from the low in the Gulf will aid in enhancing
afternoon thunderstorms in Copper River Basin. High pressure looks
to stick around through Friday night, so look forward to mostly
clear and calm weather for the next few days!

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3)...

A weakening front stretched over the Eastern Aleutians/Southern
Alaska Peninsula to Nunivak Island, bringing widespread rain and
small craft winds to the region. There`s a small corridor of gale-
force winds currently near the Pribilof Islands shifting northward
tonight as the front continues to weaken. Tonight, a new low
pressure system will enter the Western Bering, phasing with the
previous low pressure system, re-initiating precipitation across the
Western and Central Aleutians as well as maintaining the
southwesterly winds. The new front will similarly sweep the Aleutian
Chain through Wednesday into Thursday night bringing periods of
light-to-moderate rainfall across the area. The Kuskokwim Delta
Coast and Nunivak Island have the best chance to see rain while the
rest of Southwest remains on the drier side, though cloud cover
will gradually spill into the rest of the Southwest mainland over
the next few days.

Expect steady onshore flow into the Kuskokwim Delta coast to persist
beyond midweek. This will coincide with the full moon and
astronomical high tide, potentially resulting in coastal waters
rising slightly higher than the highest astronomical tide line. This
pattern may persist into the early weekend, and as the front moves
over the Southwest coastline by late Friday, onshore winds may
increase.

.LONG TERM FORECAST (Days 4 through 7: Saturday through
Tuesday)...

Not much change from yesterday`s long term discussion. Expect
generally unsettled weather as several lows move across the region
late this week and into early next week. The worst conditions
during this 4-day span will likely be focused along the Eastern
Bering Sea, Alaska Peninsula, Southwest Mainland, and Kodiak
Island as a robust North Pacific low moves north along the
Southwest Alaska coastline through Saturday. Increasing
confidence in the low track means that there is also increasing
confidence in gusty winds winds through the gaps and passes of the
Alaska Peninsula, as well as through Kamishak Gap and into
interior Bristol Bay. Additionally, periods of moderate to heavy
rain will also be likely along the Pacific side of the Alaska
Peninsula given the plentiful moisture advection associated with
this storm. As the low will move through rather quickly, total
rain accumulations shouldn`t be too excessive. Another storm
grazes the Central/Eastern Aleutians and Southern Alaska
Peninsula Saturday afternoon through Sunday, then slides south
into the North Pacific through Monday. With the storm track
remaining further south, the worst conditions will remain
offshore. For the western Bering/Aleutians, fairly quiet weather
with winds expected to remain below 25 kt and areas of rain
showers.

Shifting gears to Southcentral ALaska, easterly waves emanating
from a retrograding upper low will lead to more widespread rain,
and a transition away from the warmer and drier conditions earlier
in the week. The placement of the upper low continues to vary
greatly among the models, leading to uncertainty with the timing
and extent of rain.
