Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 449 PM AKDT Mon Mar 18 2024
.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)...
Light snow and sea-level rain will continue to diminish this evening as the responsible low dissipates in the Gulf of Alaska. A ridge of high pressure will amplifying across southcentral Alaska today and tomorrow and remain in place through midweek. This will result in generally quiet weather for the area.
The biggest forecast challenge in the short term will be the extent of lingering low stratus and/or fog across Cook Inlet and the Copper River Basin tonight into Tuesday morning. There is also the potential, if low clouds and fog do linger, for pockets of freezing drizzle from Kenai to Anchorage Tuesday morning. Forecast confidence in this scenario is low; however, there continues to be support for this in forecast model soundings.
.SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS (Days 1 through 3)...
Rain, snow and gusty winds will persist in the Bering Sea through tomorrow as a strong front continues its northward progression.
Observations on the Central Aleutians showed a changeover to rain earlier today at Dutch Harbor and Cold Bay with wind gusts in the 30 to 40 mph range. Strong southerly winds in the North Pacific and Bering Sea will continue through Wednesday evening. Gap winds are forecasted to range from 50 to 60 mph in the Eastern Aleutian Islands; fastest from Dutch Harbor east to Nelson Lagoon.
Snow and wind gusts ranging from 30 to 40 mph that created blizzard conditions in the Pribilof Islands this afternoon are slowly diminishing. Warmer air will continue to flow into the area increasing temperatures above freezing and change the lingering snow showers to rain. Wind gusts also continue to diminish quickly this afternoon. Looking ahead across the Bering Sea and Aleutians, southerly to southwesterly wind flow is expected to continue through mid- week with decreasing winds after Thursday.
Later tonight, snow and wind gusts ranging from 30 to 40 mph in will arrive in Toksook Bay and northward along the Kuskokwim Delta coast. A blizzard warning is in effect this evening through tomorrow morning in this area. Snowfall amounts here are forecasted to reach 5 inches and combined wind gusts as high as 40 mph, will create visibility reduction to a quarter mile at times.
.LONG TERM FORECAST (Days 4 through 7: Friday through Sunday)...
A highly amplified pattern, featuring deep troughing over the Bering Sea and Aleutians and a strong ridge across much of Mainland Alaska and the Gulf remains throughout the period. This large scale weather pattern will favor above average temperatures across all of Southern Alaska. While drier weather and mainly calm conditions are expected for Southcentral Alaska under the ridge, a warm and stormy pattern is in store for the Bering Sea, Aleutian Islands, and Southwest Alaska as multiple waves and storms move through. The biggest challenge in the long term will be honing in on the track and evolution of these storms, and the timing on when the ridge begins to break down, allowing for any moisture to make its way into Southcentral Alaska.
The first major storm complex will be on Friday as models show a sub-980 mb North Pacific low/low complex moving north and crossing the Aleutians sometime Friday into Saturday. However, confidence in the exact details of the low(s) itself still remains low, leading to high model variability in the location and timing of the heaviest precipitation and strongest winds. The GFS and various ensemble members show a single strong, occluding low, while the EC/Canadian begin to form a low complex with multiple precipitation and wind maxima.
Forecast confidence continues to decrease by Saturday, with the question of whether the aforementioned low and troughing is strong enough to begin to break down the ridge extending across much of Alaska and the Gulf. Due to the single low, the GFS/GEFS keep the ridge in place continuing drier and calmer conditions across Southcentral, while the Canadian/EC and some of their respective ensembles push a front from the easternmost low eastward, bringing stronger winds and widespread precipitation into Southcentral.

AVIATION
PANC...The MVFR-level stratus in upper Cook Inlet is expected to persist around the airport for the overnight hours and may lower to IFR for the early morning hours. With this low stratus and a very dry midlevel airmass moving in, there is a chance for some periods of freezing drizzle to develop late tonight into the early morning hours. This is not a sure thing by any means, but the atmospheric set-up is conducive for freezing drizzle, especially if the stratus does thicken and lower late tonight.
The other big question is if the stratus will finally clear out Tuesday afternoon or mainly stick around into Tuesday night.
