Marine Weather and Tide Forecast for Ugashik, AK

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

The pattern of persistence across Southwest Alaska and the Bering Sea continues with minimal changes through the middle of the week. The blocking ridge will remain anchored over the western Aleutians deep into the week while northerly flow remains ever present. Southwest Alaska remains clear, cold, and dry through the first half of the week, while elevated northerly winds continue to promote intermittent blowing snow and reduced visibilities along the Kuskokwim Delta coast. Continued troughing in the Gulf of Alaska will similarly allow winds elsewhere across the Alaska Peninsula and the eastern Bering to remain gusty, leading to areas of heavy freezing spray in coastal waters along the ice edge and the Pacific-side of the Alaska Peninsula.

Through the remainder of the week, reinforcing shots of cold air advection across Southwest Alaska will trend temperatures colder once again with overnight and morning wind chill values falling into the -20s to -30s. Across the Bering Sea, weak shortwaves rounding the ridge will promote brief periods of snow showers for the Pribilof Islands and portions of the Aleutian Chain.

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

The long-term period begins with stubborn high pressure persisting across the western Bering Sea and Western Aleutians through Thursday. There are indications that this high pressure system will slowly move eastward to the central Bering and Central Aleutians through the end of next weekend. This would open the door to moisture from a series of North Pacific fronts making it over the Western Aleutians while the Central Aleutians remain relatively quiet.

Meanwhile, the Eastern Aleutians, the Pribilof Islands, and Alaska Peninsula (AKPEN) will continue to be within cold northerly flow coming off of the Bering through the long-term period.
Therefore, in this northerly flow pattern, expect snow showers from time to time across the locations mentioned above through the long-term period. Mainland Southwest Alaska looks to mainly stay dry and cold as the current pattern persists. Any snow showers will remain confined to the mountain ranges.

Out east towards Southcentral Alaska, a low pressure system will remain in the Gulf of Alaska through the long-term period. This will help to maintain enhanced gap winds through the favored terrain and passes. Expect the majority of precipitation, in the form of snow, to remain across the coast and coastal mountain ranges of Prince William Sound, the Eastern Kenai Peninsula, and the southern facing slopes of the Chugach Range along the north Gulf Coast. Most inland locations look to remain on the dry side with maybe portions of the southern Copper River Basin seeing some snow showers from time to time making it across the Chugach; especially Thursday and Friday.

AVIATION

PANC...VFR conditions are expected to persist into Tuesday with a trough of low pressure to remain southeast of Anchorage through the latter half of the week. The pressure gradient on Monday will favor northerly winds gusting up to around 30 knots. Winds will peak in intensity by late this evening, before diminishing into the 15 to 20 knot range on Tuesday.
