Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 447 AM AKST Sat Dec 16 2017 .ANALYSIS AND UPPER LEVELS... A sprawling upper level low encompasses the eastern Bering and southwest mainland this morning, promoting widespread shower activity across much of the region as broad and relatively unstable onshore flow remains focused over Southcentral AK. A strong front is pushing inland along the North Gulf Coast, bringing steadier rain to coastal locations and initiating a brief push of gusty southeast winds into the Anchorage and Palmer areas as the down inlet pressure gradient is quickly reversed by a meso low moving up the inlet. Farther west, more snow is beginning to mix in with the abundant showers over the central Bering as colder air filters into the region on the back side of the low. && .MODEL DISCUSSION... Models remain in excellent short term agreement as the low shifts eastward into the Gulf by Sunday, continuing the recent cooling trend across the southern mainland. Shower activity will also trend down across the region by late Sunday into Monday as the low pulls off to the east and transient ridging moves in behind it, initiating a brief offshore flow regime. Attention then turns to a strong front sweeping across the Bering from west to east on Sunday as deep low parallels the Kamchatka coast. Primarily used the NAM for the morning package given the strong overall agreement, but also blended in some GFS for the next Bering system as it depicts slightly stronger winds along the front. && .AVIATION... PANC...VFR conditions are expected to prevail through most of the TAF period in a showery southwest flow regime, however occasional MVFR conditions will remain possible through this evening as any showers move over the terminal. A departing front will bring a brief window of gusty southeast winds to the terminal early this morning, with winds diminishing somewhat by mid morning and then continuing to trend down through the afternoon as the pressure gradient weakens. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)... The upper low along the west coast of Alaska will move east through Sunday night, with its axis centered near the Kenai Peninsula around noon Sunday, and south of Yakutat late Sunday night. The front along the north Gulf coast will move inland and dissipate today, with winds diminishing over most land areas. Showers will continue over southern Alaska as the trough traverses the area. This will also usher in a colder air mass, with snow levels dropping to the surface this afternoon and tonight. A ridge will build into the area later Sunday and Sunday night. This will set up an offshore flow regime at the surface, with the usual areas (such as Whittier and Seward) seeing gusty winds. Showers will end from west to east Sunday afternoon through Sunday night. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)... Low pressure along the eastern Bering keeps ongoing showers across the Southwest through Sunday night then slides across to the gulf. Precipitation will mainly be snow with cooling temperatures aloft, however a slightly modified air mass along coastal Bristol Bay may bring a brief period of rain showers during peak heating today. Gusty south winds shift to the west and north late sunday as the surface low departs. The next front moves to the southwest coast early Monday bringing strong southerly winds and snow as it pushes eastward. There is still a bit of uncertainty with this system for precipitation types, but it looks like a warmer air mass changes snow over to rain along the much of the southwest coast and just inland across Bristol Bay. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)... An active pattern continues through Tuesday night as low pressure over the east Bering exits to the Gulf and is quickly followed by a stronger North Pacific storm system. The first system currently spinning over Nunivak Island advects colder air from eastern Russia which pushes across the Aleutians and Alaska Peninsula tonight. Weak short waves rotating about the upper level low will bring snow showers along the northern waters through Sunday, with a mix of rain and snow along the southern waters changing over to snow tonight. The next powerful storm system moves to the western Aleutian Chain late tonight and quickly spreads precipitation and strong gusty southerly flow to the central Bering by Sunday afternoon. Precipitation along the front may start as snow, however this warm core system changes the type quickly over to rain as a strong subtropical jet amplifies across to the northern Bering. Gusty southerly flow continues through late Tuesday as the storm center remains organized as it slowly fills on a northerly track toward the Bering Strait. && .LONG TERM FORECAST (Days 3 through 7...Mon through Fri)... The weather picture for next week is starting to become clearer. There are 2 major features to focus on. The first will be a very deep low over the Western Bering Mon and its associated front. The low will bottom out somewhere in the 945 mb range late Sun into early Mon. But its trek across the Bering will impact the whole area to start the week. Along the front, storm-force winds and moderate rain should be expected through the Aleutian chain as it pushes from west to east. Behind the front, expect widespread showers (transitioning from rain to snow) and gusty winds as cold air wraps around. As the front impacts SW AK, it will start out as snow with some gusty winds. This could create some difficult travel conditions, so stay tuned to this portion of the forecast. But with warm air and onshore flow, the snow should transition fairly quickly to rain. Today models have come into better agreement that this feature will hold together long enough to make it into the Cook Inlet region. If a few ingredients hold together, this could have the making of a decent snow event for the Anchorage area. But there is still a lot of time and variables that have to match before there is much certainty in this solution. The second major feature will be a building ridge over the North Pacific to end the week. There is still abundant uncertainty as to exactly where this feature will establish itself. On its western edge, it will bring moderate to heavy precipitation and warm and windy conditions. Underneath the ridge axis, it will likely be cold and foggy. Stay tuned to the forecast to see exactly how this pattern unfolds and what the sensible weather will be at the surface as we move towards Christmas Weekend. && .AFC WATCHES/WARNINGS/ADVISORIES...
