Synopsis. We are moving into a very quiet and slightly cooler period across the forecast area. Temperatures in the Arctic falling into the 20s to 40s below, while the West Coast and Interior will see temperatures in the from 5 below to 30 below Sunday, then a little warmer Monday. Temperatures will rise nicely during the day with mostly clear skies across the area. Winds will be picking up on the Northwest Arctic Coast, West Coast, across the Brooks Range, and around Delta Junction Monday. Potential for ground blizzard on the Northwest Arctic Coast as winds increase Tuesday so will keep a close watch on it.
Models . The 28/12Z set of solutions is very agreeable today for the short term. The diverge starting around 72 hours on the handling of a low moving west over the Gulf of Alaska. Solutions are handling the increasing winds on the West Coast, in the Arctic, and around Delta Junction well, so will use a blend, but will be leaning on the HIRESarw solutions as it captures the stronger winds well in the short term. Not much precipitation to talk about until Tuesday, and even then just some shower on the West Coast. Next significant precipitation will be moving up the West Coast Wednesday, then east across the state Thursday and Friday.
Aloft . At 500 hpa . A trough associated with a 486 dam low over Prince of Wales Island in the Canadian Archipelago lies over the Yukon Territory to a 514 dam low over the Copper River Basin to a 515 dam low over the Gulf of Alaska. Thr trough will continue to swing southeast to lie over Yakutat, then south to a 511 dam low 300 nm south of Yakutat. A weak trough will persist south of the Alaska Range. Ridging that was over Siberia west of the Gulf of Anadyr has moved to the Dateline and extends north to the high Arctic, and west over the Arctic Coast. Ridge will continue to slide east to the Bering Strait extending north over the Arctic, and West over the Brooks Range by Sunday afternoon. Troughing will persist over the Gulf of Alaska Coast and Northern Bristol Bay. By Monday afternoon the ridge will lie from Cold Bay to Nuiqsut and north with a 545 dam cutoff high over Nuiqsut. The high moves to MacKenzie Bay by Tuesday morning with the ridge axis extending south over Kodiak Island as a longwave trough moves over the Western Arctic and West Coast At 850 hpa. -10C isotherm is south and west of the forecast area this afternoon and the -20C isotherm lies over the Eastern Brooks Range then north from Cantwell to Deadhorse. Temperatures will generally be slowly warming as the the low over the state moves southeast and high pressure to the west moves to the Bering Strait. By Sunday afternoon the -20C isotherm will be over the Upper Tanana Valley then northeast from Delta Junction to MacKenzie Bay, while the -10C isotherm will be over the Western Interior extending north over Utqiagvik. Temperatures will continue to slowly warm through the week.
Surface . A low that was over the southwest mainland has moved to the Gulf of Alaska at 993 mb and will continue to move southeast. High pressure has moved to the northwest Arctic with a 1034 mb high 100 nm northwest of Wainwright, and a 1032 mb high has moved over the Chukotsk Peninsula near the Gulf of Anadyr. High pressure will continue to build over the state as the low moves southeast and by Sunday afternoon high pressure will extend west from a 1038 mb high near the Yukon/Northwest Territories Border across the Upper Yukon Flats to a 1038 mb high near Ambler, then southwest to a 1025 mb high near Nunivak Island. A 1030 mb low will develop in leeside troughing north of the Brooks Range with a tight pressure gradient developing across the Eastern Brooks Range producing gusty south winds near passes. The pressure gradient will also tighten across the Eastern Alaska Range with strong north winds developing near passes. The high pressure will persist in generally the same area through Monday.
Arctic Coast and Brooks Range . Winds continue to blow around Kaktovik, but will be settling down with improving conditions this evening. Wind chill will continue to be a problem so see advisories for zones 201 and 204 for specifics. Strong gusty south winds developing in Eastern Brooks Range passes Sunday night may create some travel problems. Temperatures will be warming slowly starting Sunday.
West Coast and Western Interior . Pretty nice for the moment in most areas. Strong north winds in the Norton Sound Region and Bering Strait Coast will be settling down this evening. Winds will start increasing on the capes Monday as low pressure pushes east. Temperatures warming slowly.
Central and Eastern Interior . Another cold night, but mostly clear. Warming temperatures starting Sunday. Some gusty winds north of Fairbanks so have issued a Special Weather Statement for drifting snow and wind chill along the highways and on summits. The Tanana Valley Jet is kicking along today and winds gusting to 30 mph extend from west of Dot Lake just east of Tanana. North winds will be picking up in the Eastern Alaska Range Passes so expect some blowing snow and gusts to 55 mph and visibility less than one half mile at times.
Coastal Hazard Potential Days 3 and 4 . None.
Extended forecast for days 4 to 7 . A weather system will move up the West Coast bringing a mix of precipitation to the area Wednesday, then moves northeast across the state Thursday and Friday as it weakens and dissipates near the AlCan. Another system will move into the Bering Sea by Friday evening, but models diverge on when it will make it to the coast at this time.

Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.
