Southcentral and Southwest Alaska Forecast Discussion . CORRECTED National Weather Service Anchorage AK 1024 PM AKST Sun Feb 16 2020

ANALYSIS AND UPPER LEVELS. The jet stream is in the process of amplifying and extends northeastward across the Aleutians into the southwest mainland before cutting southeastward to over the eastern Gulf and into the North Pacific. The amplifying jet stream will allow for the predominant low-track to be across the eastern Bering/Aleutians and into the southwestern mainland. A complex low pressure system with its dominant area of circulation located 100 nm east of Shemya continues to move eastward as this low is being steered by the aforementioned jet stream. Upper-level ridging currently extends over the Alaska mainland with the surface high centered in Yukon Territory. Radar imagery shows a band of light snow currently moving northeastward along the AKPEN.

MODEL DISCUSSION. Models remain in good agreement with the overall synoptic pattern through Monday afternoon. Models begin to diverge over the North Pacific Monday night with the next low pressure system that is expected to move into the central Gulf. Models are similar with the general track of this low but significantly vary in the intensity of the low. Tuesday onward, models show significant differences with the intensity and placement of lows, thus forecast confidence remains low at this point.

AVIATION. PANC . VFR conditions and light winds will persist through this evening. Conditions could drop to MVFR in light snow later tonight and continue into the late the morning hours. VFR conditions are expected beginning late Monday morning, but LLWS should develop as winds aloft increase.

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

A weak warm front is sliding across the southwest Gulf of AK this evening. This will bring a quick shot of snow to Kodiak Island before it transitions to all rain. This front will then make its way into the southern Kenai Peninsula later tonight before pushing into the Prince William Sound by Mon morning. As it makes landfall along the coast, precipitation will initially start as snow with some light accumulations expected. There could be pockets of blowing snow through the Portage Valley and Turnagain Pass on the leading edge of this front early Monday. However, as the winds push in, warm air will accompany them. This should cause the snow to mix with rain, especially at lower elevations and coastal sites. Further inland over the Susitna Valley, the air will remain cold enough to support all snow.

A strong developing low over the eastern Bering will propagate another front on a nearly identical track across the Kenai Peninsula and into Prince William Sound. There will be great amounts of precipitation for many of the coastal locations due to the abundant moisture and deep southerly flow. This system will bring strong southeast winds to the Turnagain Arm, the Anchorage Hillside and parts of the Matanuska Valley. These winds are expected to push in during the day Monday and eventually into the Anchorage Bowl late Monday night. Warmer temperatures will accompany these winds as they serve to mix down some of the warmer air aloft. The winds will also serve to downslope many of these same areas keeping them mostly dry. The western Susitna Valley will remain cold air, however, as southerly flow will create impressive snow rates. Several inches of new snow accumulation are expected there through Tuesday morning.

Following this, a cold front will enter the area from southwest Alaska late Monday into early Tuesday. Deep southerly flow will allow for widespread moderate to heavy precipitation to continue across much of Southcentral, especially in coastal areas. As the cold air moves in, this should change all of the precipitation to snow. There could be significant accumulations through Turnagain Pass, the Susitna Valley and Thompson Pass. Winds will remain gusty in some locations, so blowing snow will also remain a threat. This setup will also provide the Anchorage Bowl its best chance for accumulating snow. For now, winter weather products were issued for the Susitna Valley and Thompson Pass for conditions on Tuesday. Stay tuned for forecast updates.

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

A broad upper low over the western Aleutians will be the general focus in the short term. A surface low in the eastern Bering associated with a shortwave of the parent low is swinging a warm front across the Southwest Mainland. Snow has started along the Bering Sea coast, from Toksook Bay to Egegik. South flow behind the front will transition precipitation to rain or a rain/snow mix in the low lying parts of the Greater Bristol Bay area tonight.

Over the Kuskokwim Delta, a Blizzard Warning is in effect starting at 6 PM today for areas west of Bethel. With deep cold air in place and steady gradient-driven offshore flow, expect significant visibility impacts particularly to the Kuskokwim Delta coast north of Kipnuk. Conditions will briefly improve late tonight. Another secondary low currently centered roughly 140 miles south of the central Aleutians will quickly track north into the Bering Sea. This will bring another healthy round of precipitation Monday to the Southwest Mainland, as snow or a rain/snow mix in the Bristol Bay area and snow in the Kuskokwim Valley/Delta. Blizzard conditions will return to the Delta by mid-morning. With this second punch, winds will likely be stronger and snow heavier. Gusts up to 45 mph are expected along the coast, with 4 to 6 inches of snow in the Kuskokwim Delta. Again, the worst conditions will be along the coast, but there will be potential for blizzard or near blizzard conditions farther inland (e.g., Bethel) Monday morning. Meanwhile, as the low continues its track north, cold air wrapped around the backside will bring a return to snow to the Bristol Bay area. This changeover should occur Monday afternoon/evening.

The low will weaken and shift inland Tuesday, and surface winds will diminish and become more southwesterly. Snow showers will persist over the entire Southwest Mainland, but precipitation rates will have a significant drop-off.

SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2).

A broad upper low over the western Aleutians will continue to bring snow showers and gales to the western Aleutians tonight. Meanwhile, a secondary low centered over the Pribilof Islands will continue to bring snow and increased winds to the Pribilof Islands/eastern Bering. Snow may briefly change over to a rain/snow mix, but should switch back to snow this evening as the low tracks north. Another secondary low currently located roughly 140 miles south of the central Aleutians will quickly track north late tonight Expect gales along its south side. with an embedded swath of storms force winds. A High Wind Warning is in effect for the AKPEN, including Cold Bay and King Cove for late tonight. This low will bring a healthy shot of precipitation to the eastern Aleutians and AKPEN. The low will track east of the Pribilof Islands, triggering another round of precipitation early Monday morning which looks to be all snow. While much will depend on the exact track of the low (which has some uncertainty), it's looking more and more likely that the heaviest snow and strongest winds will stay west of the Pribilof Islands. So, while there may be periods of reduced visibility in blowing snow, significant impacts look unlikely at this time. However, if the low tracks farther east than expected this could change. The ensemble spread indicates that this feature bears watching.

In any case, as the low weakens and tracks northeast towards the mainland, expect broad north flow over the Bering Tuesday, the area of gales on the backside of the low diminishing throughout the day.

MARINE (Days 3 through 5 Wed through Fri ). A low over the western Aleutians Wednesday morning will slide eastward, reaching the Gulf Thursday night and Friday. Gale force winds are expected with this system. Some storm force winds are possibly Wednesday and Wednesday night around the Aleutians.

LONG TERM FORECAST (Days 4 through 7 Thu through Sun). On Thursday morning the pattern will consist of an upper low over the Bering Sea, with an associated trough extending southeastward across southwest Alaska. The trough will very slowly slide northeast across southern Alaska through Sunday as the main upper low retreats northward. An upper level Ridge is expected to move into the Aleutians and southern Bering as the low moves north on Friday and Saturday. An upper level low just west of the Aleutians on Friday will move into the western and central Aleutians Friday night through Sunday, though the exact path and timing of this feature is somewhat uncertain.
