Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 426 PM AKDT Thu Apr 17 2025

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3: This afternoon through Sunday afternoon)...

Few changes to the forecast. Expect improving conditions through tonight, then fairly benign conditions from tomorrow through Saturday. By Sunday, a gradual transition towards more active weather as an occluding front moves over Kodiak Island and approaches Mainland Southcentral. Forecast confidence is good, though there's minor uncertainty with the timing of showers from now through tomorrow.

A highly amplified pattern, one more akin to fall than spring, will shift east over the weekend, bringing a steady end to precipitation and wind to most of the region by Saturday. However, breezy conditions and widespread rain/rain showers will persist through tonight as the main upper level trough and a few attendant shortwaves move over the area. The flow aloft will be largely out of the south, focusing more the moderate precipitation on the eastern Sound (Valdez/Cordova) and to a lesser degree Seward.
Inland areas will see rain spread southwest to northeast through the day and into the evening as a few shortwaves move overhead.
Snow levels will slowly fall below 1000 feet by tomorrow morning as cooler air moves in from the west.

For tomorrow, most of the upper level forcing for precipitation will have moved into the Gulf, leaving behind a weak low in the northern Gulf and a more unstable airmass. The low in the Gulf may keep some areas around the Sound, particularly near Valdez and Cordova, a little on the wet side while the instability inland yields shower development near south and west facing mountains.
These showers should follow a diurnal cycle, with snow falling above approximately 800 ft in elevation. It may make it down lower in a few areas, but little to no accumulation is expected during the afternoon hours at or near sea level.

Saturday appears to be the nicest day of the week, with shortwave ridging bringing in some sunshine for many areas. A weak shortwave trough embedded in the flow is expected to move over the Alaska Range, which may lead to some showers or cloudier conditions over the Susitna and Copper Valleys, but from the southern Mat-Su south through the Inlet and into the PWS should be sunny or at least mostly sunny. This looks to extend into the first half of Sunday, but clouds and precipitation will slowly push back in to Kodiak by Sunday morning and then into Southcentral late Sunday into Monday morning.

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

The low pressure system moving inland into Southwest Alaska has continued to bring widespread rain and snow across much of the region this afternoon. Rain has become the predominant precipitation type across much of Southwest except for the Kuskokwim Delta Coast and Western Capes as they remain in the cold air advection regime. As the low continues to weaken as it exits to the east, precipitation will begin to clear out through this evening and overnight. Expect any lingering precipitation throughout tonight and the early morning hours of Friday to transition back to snow as colder air on the back side of the trough spreads back over the region. Gusty westerly to northwesterly winds along the Alaska Peninsula will also continue to decrease throughout this evening and tonight as weak ridging currently over the central Aleutians slides to the east. This strengthening ridge will make its way over Southwest Alaska for the weekend, leading to drier and warmer conditions through Saturday.

A weak front currently passing over the central Aleutians continues east to the Eastern Aleutians before falling apart Friday morning, bringing light precipitation to the island chain and ushering in a warmer airmass. By Saturday morning, a North Pacific low lifts across the western and central Aleutians into the Bering, driving a front into the central/eastern Aleutians by Saturday afternoon, bringing increased wind speeds and precipitation mostly in the form of rain. The front pushes into the Southwest mainland by Sunday morning, with precipitation falling in the form of rain apart from the Kuskokwim Delta coast where precipitation may begin as a rain/snow mix before quickly transitioning to rain.

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

A broad upper level low dominates the Alaska Weather map moving from the Bering to cover Interior Alaska by midweek and flexing through the end of the forecast period. A few upper level low centers and several shortwaves moving through the flow keeps the overall pattern fairly unsettled, but most of the active weather will occur across the Southern portions of the state. A well clustered mix of GFS / ECMWF / UKMET and Canadian models support large scale feature movements and strengths, with the greatest uncertainty bundled in the smaller surface details.

On the surface, a large area low center in the West-Central Bering extends a front across Southwest Alaska and the Alaska Peninsula into the Gulf of Alaska on Monday. Areas of snow or rain mixed with snow move over the Northern Bering and Southwest Alaska, with all rain spreading over Kodiak Island, Southcentral Alaska Coast and the Gulf of Alaska on Monday. This low weakens as it moves into Bristol Bay and dissipates early Tuesday. A low forming South of the Aleutians picks up the slack Tuesday, bringing another round of rain across the Gulf of Alaska and Southcentral Alaska through Thursday. Developing in the West, a strong North Pacific low pushes a front over the Western Aleutians and Bering Tuesday. Locally heavy rain and gusty winds spread Eastward through Thursday.
