.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)...
This mornings satellite imagery shows the elongated trough over the Bering has pushed through the Aleutians and into the North Pacific as the southern end starts to deepen. On the eastern periphery of this trough, a compact low is quickly progressing northward towards Kodiak Island...dragging with it a modest moisture plume. Winds have rapidly strengthened across the western Gulf, especially between Kodiak Island and the southern Kenai Peninsula where easterly winds are already gusting between 40 to 50 mph this morning. With a new upper low developing on the southern end of the Bering/North Pacific trough, and the amplified ridge over the eastern Gulf and western Canada, the pressure gradient will continue to tighten over the western Gulf. Storm- force winds expected this afternoon and evening from near the Barren Islands to Kamishak Bay with a large swath of gale-force winds over the western Gulf continuing into Friday morning before the gradient begins to slacken.
In addition to strong winds, moderate to heavy rainfall will impact Kodiak Island today and tomorrow. Models remain in good agreement with the front stalling near Kodiak through Thursday...possibly into Friday...before parent low starts to lift north and the front moves towards the northern Gulf coast. Increasing PWATs at Kodiak per the 12Z raob indicates the moisture plume has arrived, and combined with semi-consistent upslope over the next few days, will result in efficient precipitation processes. Still decent confidence that lower elevations on the east side of Kodiak could see anywhere from 3 to 5 inches of rainfall through tomorrow night. Given that ground temperatures are still fairly cold, will likely see some ponding of water, especially in low-lying areas.
Temperatures should remain warm enough that the lower elevations will see all rain. The southeast quadrant of the Kenai Peninsula will also see moderate precipitation with up to several inches of rainfall for lower elevations and modest snow accumulations for higher elevations across the Kenai Mountains. Conditions also look favorable for rainfall to work into Kachemak Bay, and combined with gusty winds, will make for a wet and blustery few days.
Looking ahead to the end of the week and into the weekend...the low will remain parked over the southwestern Gulf with showery conditions lingering for Kodiak, the eastern Kenai, and western Prince William Sound areas.

.SHORT TERM FORECAST SOUTHWEST ALASKA, THE BERING SEA AND THE ALEUTIANS (Days 1 through 3)...
A low pressure system south of the Aleutians will continue to bring southeasterly winds to portions of the Bristol Bay region into this evening. Wind gusts overnight were recorded in New Stuyahok and Koliganek ranging from 35 to 45 mph. Today, the highest wind gusts will drift just south of New Stuyahok as the front moves northward along Kodiak Island this afternoon and evening. Gusts as high as 70 mph are possible this afternoon in areas just south and east of New Stuyahok. Precipitation overnight has ranged from rain and snow to a rain/snow mix throughout many places. As temperatures rise today, mostly rain will fall. However, pockets of snow or a rain snow mix are possible through late this morning.
Persistent northerly winds today will bring a band of snow showers to the Eastern and Central Aleutian Islands as well as Kuskokwim Delta coastal areas. Total accumulation of this snow range from 5 to 10 inches through later this morning with amounts ranging from 6 to 12 inches in the Eastern Aleutians through late tomorrow morning. Wind gusts reaching as high as 55 mph could reduce visibility to as low as one half mile at times today, too.
Unsettled conditions continue until the end of the week.

.LONG TERM FORECAST (Days 4 through 7: Saturday through Tuesday)...
A moderately strong area of high pressure over the the Northern Canadian Provinces extends a ridge across Mainland Alaska through the forecast period. The strength of the ridge weakens, but holds its orientation across Interior Alaska. In the Gulf, a persistent closed low remains nearly stationary linking up with a second low in the Bering. The Gulf low will also weaken through the weekend as the Bering low is expected to drift over the Mainland ridge into the Arctic through Tuesday. The Gulf low moves into a bigger loop through Tuesday. A North Pacific low moves over the Aleutians for the beginning of next week.
A front connecting the Gulf low with the Bering low provides the stream for an extended period of wet weather from the Southern Kenai Peninsula across Kodiak Island into the Alaska Peninsula.
Widespread rainfall will continue with locally heavier periods of rain will bring several additional inches through the weekend. A trough swinging around the low spreads rain over much of the Southcentral coast. Southwestern Alaska may see mixed rain and snow to the West of the vertically stacked trough, with snow expected further North along the Western Coast.
