Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 435 PM AKDT Tue Apr 16 2024

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)...

An upper level ridge centered over the ALCAN border continues to slide eastward, allowing a trough over the central Bering to deepen and stall, strengthening a North Pacific low south of Kodiak and the western Gulf. This new low will remain in place for several days. While most of Southcentral will experience a slight warming trend, this system is expected to bring moderate to heavy rain to Kodiak Island and portions of the eastern Kenai Peninsula lasting through Friday. In addition, gale to storm-force winds winds will develop across the western Gulf and Barren Islands tonight through Wednesday.

Several shortwave troughs on the southern periphery of the longwave trough will lift north towards Kodiak Island and into Southcentral. The heaviest period of precipitation is expected on Wednesday around noon. Temperatures may initially be cold enough at lower elevations to begin as a rain/snow mix on Kodiak, but should quickly warm and change over to all rain by Wednesday afternoon.
Moderate to heavy rainfall looks to persist into Thursday, but could see showery conditions linger through Friday. Models remain fairly consistent with rainfall amounts of about 4 to 6 inches along the southeast side of Kodiak and up to several inches for lower elevations along for coastal areas for southeast Kenai Peninsula. Elsewhere precipitation is expected to be light to dry.
No measurable precipitation expected for the rest of the week from Soldotna to the Mat-Su Valley.

.SHORT TERM FORECAST SOUTHWEST ALASKA ,THE BERING SEA/ALEUTIANS (Days 1 through 3)...

A decaying front draped over the Y-K Delta this afternoon continues to be the focus for areas of mixed rain and snow from Aniak to Toksook bay. This front will continue to weaken as it remains nearly stationary overnight, replaced by an inverted trough extending northward from a North Pacific low advancing toward the Alaska Peninsula. Moisture associated with the low will stream northwestward, along broad southeasterly winds aloft. The moisture will concentrate along the trough axis, wringing out over the Kuskokwim Delta overnight and into Wednesday morning. Winds near the surface will turn a bit more northerly, allowing enough colder air to advect at lower levels for the precipitation to fall mainly in the form of snow, especially from Bethel west. The heaviest snow is expected over the Kuskokwim coast, right along the trough axis. 5 to 10 inches of snow is possible before warmer air works back in Wednesday afternoon, allowing for a mix with rain. Farther south across Bristol Bay, enough warmer air and a southeasterly wind should allow for precipitation to fall mainly in the form of rain.

As the low lifts north tonight, the pressure gradient between it and a stout ridge anchored over the Alaska Panhandle will tighten.
The result will be an increase in winds through Kamishak Gap and across interior Bristol Bay, where wind gusts could peak around 70 mph by Wednesday morning. Farther along the coast, winds will not be as strong, but gusts of 45 to 55 mph are not out of the question.

For the Bering and Aleutians, precipitation from the trough will likely extend southwest from the Kuskokwim Delta to the eastern Aleutians. Colder air on the west side of the trough will allow temperatures to drop to around freezing overnight. A second shortwave diving south from east of the Russian coast will advect colder air in aloft for Wednesday just as the moisture axis pivots toward the Aleutians. The result looks to be moisture moving into an increasingly cold and unstable airmass, with the potential for heavy snow over the eastern Aleutians. Places like Unalaska / Dutch Harbor could see several inches of snow, the current thought is 6 to 12 inches, along with northerly wind gusts of 50 to 60 mph for Wednesday. The moisture axis looks to stay just to the east of the Pribilofs; however, if there is any westward jog in this system, snow may accompany the gusty winds across Saint Paul and Saint George Islands as well.

The unsettled conditions will continue into Thursday and Friday; however, winds will slowly diminish from their peak Wednesday and precipitation will become more showery and not as widespread.

.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. 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.
