Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 504 AM AKST Fri Jan 28 2022

ANALYSIS AND UPPER LEVELS.

An upper level low digging southwards across Bristol Bay towards Kodiak today will inevitable cut off forcing for precipitation across western Southcentral, with snow beginning to taper off by the mid morning hours. The system then skates across the southern Gulf towards the Southeast Coast by Saturday night. Meanwhile, a series of shortwaves within the inverted trough moves across the North Gulf Coast and Prince William Sound areas, leaving them stuck in prolonged periods of precipitation through tonight. The weakening surface low lingers in the Gulf through late Saturday night before moving off to the southeastern Gulf by Sunday morning.

Out west, most of Southwest to the Central Bering are trapped under an upper level ridge, sweeping in cold Arctic air from the Interior. A strong vertically stacked low is pushing towards the Western Aleutians and into the western Bering through tonight before shifting northwards, moving off towards the Kamchatka Peninsula early Saturday morning. The front off another separate North Pacific low moves into the southern Bering by Sunday morning.

MODEL DISCUSSION.

Models are in good overall synoptic agreement through the short term. There are still some light discrepancies with the low meandering in the Gulf, mainly with a couple models wanting to develop a triple point low near Kodiak later today. Another North Pacific low is being tracked through the eastern Gulf before eventually reaching the North Gulf Coast. There is some struggle with pinpointing the center location but they are in relatively good agreement on low strength. Further west, models are handling a large low east of Adak quite fairly well as it enters the western Bering before shifting north towards the Kamchatka Peninsula.

AVIATION.

PANC . MVFR to IFR conditions are expected to persist through mid morning or once the snow begins tapering off. Cloud decks should lift to 5000' by late morning and continue improving beyond that.

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

The cold upper level low is dropping southward along the Western part of the Alaska Range this morning. As it heads southward and cuts off, it will end the snow in the inland parts of Southcentral leaving just some rain and snow along the immediate north Gulf coast. That remaining precipitation is the result of a weakening surface low in the northern Gulf as well as onshore flow around this low.

In general it looks like the snow is pretty much over for Anchorage and points farther north. Due to the location and interaction of the upper level low and the surface low, the western Kenai Peninsula will continue to see snowfall through the morning. The snow bands that have been oriented north-to-south for the overnight period will pivot to have a more northwest-to- southeast orientation as the morning goes on. This will likely push the back edge of the snow west of Kenai early this morning, but keep the snow persisting south of there and through Homer for most of the morning. Winds are also picking up along the Inlet so kept the Winter Weather Advisory out until noon today for the Western Kenai Peninsula. The main concern is for snow and blowing snow along the Sterling highway south of Soldotna.

Looks for a clearing and cooling trend through the weekend across Southcentral as northerly flow and high pressure move over the area.

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

Clear and cold conditions will continue through the short term with gusty winds expected today. An upper level low over Bristol Bay will dive south bringing colder air today. This low will pull moisture from the low over the Gulf and bring a chance of light snow to eastern portions of Bristol Bay mainly near Iliamna and south towards Katmai National Park. Gusty winds will continue Saturday across the Kuskokwim Delta, but will weaken over Bristol Bay. A few clouds may hang around Bristol Bay on Saturday, but overall clear and cold conditions will continue. On Sunday it will warm a bit as the winds weaken with temperatures a few degrees warmer than previous days.

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

Gap winds will continue south of the AKPen through Saturday morning as cold air moves south with storm force gusts expected. Meanwhile out over the western Bering and Aleutians a low pressure system will bring a swath of Gales with small pockets of storm force winds near the low through Saturday. In between these two systems from the northern Bering towards the eastern Aleutians high pressure will prevail with quiet weather conditions expected through Saturday. On Sunday another low pressure system approaches the central and eastern Aleutians with Gale force winds expected.

MARINE (Days 3 through 5 - Sunday through Tuesday).

Gulf of Alaska:

A weak trough persists across the Northern Gulf through Tuesday. Weak high pressure moves across the Southern Gulf through Tuesday. Forecast confidence is good. A front enters the Western Gulf for Tuesday. Gusty winds ahead of the front. Seas to 15 feet over the Southern Gulf through Tuesday. Seas to 20 feet behind the front along the Alaska Peninsula Coast for Tuesday.

Bering Sea/Aleutians:

A well developed low exits the Western Bering by Tuesday. Gales diminish over the Western Bering, with 22 feet seas subsiding Monday. Forecast confidence becomes mixed with the approach of two low centers and their development through Tuesday. A well developed low crosses the Central bering Monday and moves to the Western Bering to dissipate Tuesday. Another well developed low moves to the Southwest Bering by Tuesday. Gusty winds over the Bering increase to gales with areas of storm force winds near the lows, spreading into the Northern and Eastern Bering by Tuesday. Seas building to 20 feet over the Bering through Tuesday. Seas to 20 feet on the Pacific side of the Eastern Aleutians and Alaska Peninsula for Tuesday.

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

The present Omega block pattern breaks down and gives way to a broad upper-level gyre over the North Pacific and Bering, with ridging to the east across the Gulf of Alaska and the southern mainland for next week. Several shortwave troughs are expected to rotate through the upper-level gyre, bringing periods of gusty winds and a mix of rain and snow to the Bering/Aleutians. Despite uncertainty in the timing and placement of any specific synoptic- scale feature, the longwave ridge looks to progress slowly eastward as each successive front pushes closer to and eventually inland across Southwest Alaska. As a result, expect a gradual transition to warmer temperatures and more active weather with the potential for precipitation type issues across Southwest.

Southcentral looks to remain colder and drier with ridging remaining in place for longer. However, there is some agreement that a weak disturbance enters the Gulf of Alaska on Tuesday, which could produce some brief precipitation, primarily snow, for Southcentral. Toward the end of the week, a warmer, wetter regime makes a potential return, with chances for rain and mixed precipitation type across Southcentral as stronger shortwaves begin to make it further east.
