Marine Weather and Tide Forecast for Perryville, AK

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

A transient high pressure ridge moves across the Bering Sea towards Southwest Alaska through tonight. Light lingering rain showers are expected through this afternoon for the southwest Mainland that should taper off tonight as the weak ridge passes through. Out west, a large, gale force low moves into the western Bering Sea. The associated front moves over the Western Aleutians this morning, bringing rounds of rain showers and gale force winds. The front weakens as it tracks across the Aleutians, with winds remaining below gale force as it moves east of the Central Aleutians, though rain is expected to track as far as the Southwest Coast through the weekend. There will be an area of colder air filtering along the backside of the low that will allow gale force winds to continue across the Western Aleutians through Saturday night. Winds are expected to diminish to small craft Sunday morning and below small craft by Sunday afternoon.

.LONG TERM FORECAST (Days 4 through 7: Sunday through Wednesday)...

A broad upper level low stretches from Siberia across the Bering before angling into the Gulf of Alaska. Several shortwaves help the low centers slip through the pattern as the low becomes more organized over the Eastern Bering and Western Mainland by the end of the forecast period. The most persistent low anchors over the Gulf of Alaska through midweek. Models favor the GFS through the new week maintaining strengths and tracks of features.

Lingering showers are expected over the Southern half of Mainland Alaska through Wednesday. A rain-wrapped low and front pushing across the Central Aleutians and Bering brings moderate rain and locally gusty winds into the Alaska Peninsula and Southwest Alaska through Monday. The low sweeps into the Gulf of Alaska, spreading the rain into Southcentral Alaska and North to the Alaska Range until Wednesday. Snow is expected over higher elevations, diminishing Tuesday. In the West, a well developed North Pacific low and front does a drive-by over the Western and Central Aleutians for Tuesday and Wednesday before curving back into the North Pacific.
