Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 519 AM AKST Sun Nov 11 2018 .ANALYSIS AND UPPER LEVELS... A very active morning weatherwise is unfolding across much of southern mainland Alaska. A strong low centered over the Bering is producing storm force winds along the Southwest Alaska coastline, with widespread gales ongoing over much of the rest of Bering, as shown by an 0808 UTC ASCAT pass over the area. A secondary low is developing over the North Pacific, which is helping move a strong atmospheric river of moisture eastward. The dry slot from the first low is moving over Southwest Alaska, which is temporarily allowing the precipitation to diminish over Bristol Bay, while a secondary dry slot is evident on satellite over the southern Gulf. This second dry slot will help slide the plume of moisture eastward, keeping the best moisture and heaviest rain over eastern Prince William Sound and the central and eastern Gulf. Numerous Winter Weather Advisories for freezing rain are in effect across the area, as warm air associated with the plume of moisture and dry slots is expected to begin transitioning the ongoing snow to freezing rain and then plain rain during the day today. However, thus far most stations have either reported plain rain, snow, or a mix of the two. The 12Z Anchorage sounding shows there has in fact been considerable warming over the lower atmosphere from just 12 hours before then, but the "warm" air is only now just starting to get above freezing at about 1500-2000 feet above the ground. Radar shows steady moderate to heavy rain ongoing along the Gulf Coast. Bands of precipitation, which for now are mostly falling as snow, are moving inland across the western Kenai Peninsula, Anchorage, and the Mat-Su Valleys. Some bright banding is evident approaching the Kenai-Soldotna area, which may be the start of Southcentral's transition from snow to rain. Southwest Alaska radars for now are much quieter relatively speaking due to the aforementioned dry slot moving over the area. The leading edge of that dry air is pushing one last band of snow northward across the Lower Kuskokwim Valley and the Kuskokwim Delta. Warm air at the ground is roughly correlated with where the dry slot air is across Southwest Alaska, as every station in Bristol Bay is above freezing, and Sparrevohn in the Lower Kuskokwim Valley has been reporting plain rain for much of the night. With colder temperatures likely in the valleys, this is a good setup for freezing rain in the Lower Kuskokwim Valley as frequently the cold air gets trapped in the valleys with nowhere to go. && .MODEL DISCUSSION... The models have different areas of agreement and disagreement this morning. They are all still consistently showing warm air spreading northward across all of southern mainland Alaska during the day today, which should change the precipitation over to all rain. Beyond that, disagreements are significant and numerous. Among the many challenges this morning continues to be timing of when (or if) any of the precipitation changes over to freezing rain on its way over to a plain rain. Many sites around the area are within a few degrees of freezing, and the warming caused by freezing rain should help to boost temperatures above freezing in a hurry, which then reduces the threat of significant ice accumulations. So far, all the stations that started out as snow and then changed to rain did not have a period of freezing rain in between, but warm air moving in aloft is in most of the models, which means it may just be delayed. Precipitation type is by far the greatest point of uncertainty with the forecast for this morning. Synoptically, the low currently affecting the area is expected to interact with multiple other waves of energy, which themselves are likely to develop into areas of low pressure over the next two days. All of the models show these multiple areas of low pressure are likely to interact with one another, leading to spiraling paths. Since much of this activity is expected to occur over the North Pacific, where there are very few, if any, observations, the model solutions on how and where each of these lows will be, even as soon as 36-48 hours from now remain highly divergent. This introduces large uncertainty into the forecast as regards wind speed and direction in any one coastal location, in addition to timing any areas of rain associated with them. As a result, forecast confidence is very low, with one of the only points of agreement being that temperatures are very likely to warm over the next few days such that most areas are well above freezing by this time tomorrow. && .AVIATION... PANC...The main point of uncertainty with the TAF continues to be timing the transition of snow over to rain over the airport. The snow thus far has been more robust than expected, and with warm air just getting into the area as seen on the sounding, it is likely to occur later this morning. Until then, MVFR to IFR conditions are expected in the light snow. Rain or freezing rain will follow the snow as temperatures warm throughout the atmosphere. The rain will continue through the day, becoming a bit more scattered by tonight. Winds are likely to remain relatively uniform throughout the TAF period out of the north, with potential for gusts from time to time. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)... An atmospheric river continues to bring a stream of moisture and warm air through the Gulf and into Southcentral Alaska. The heaviest of the precip is being hung up on the north Gulf coast but areas all throughout Southcentral Alaska are or will be getting some precip. Conditions are warm enough for areas along the north Gulf coast to see rain through Monday. Areas beyond the coastal ranges have started as snow but should transition over to rain throughout the day. The challenge will be if areas around Cook Inlet through the Susitna Valley will be able to hold onto freezing temperatures at the surface allowing for freezing rain as warmer air overrides the cold surface airmass. At this point it does look likely that there will be a brief period of light freezing rain this morning transitioning from south to north over the area. There is higher confidence that the Copper River Basin will see freezing rain today with a better setup to hold onto freezing temps at the surface as warm air moves in aloft from the south. This area will also see the transition from snow to freezing rain to rain move from south to north today. Further south, Thompson Pass blizzard conditions look to continue through the early morning before temps increase and winds weaken. Precip will lessen somewhat Monday morning before another trough swings through bringing another round of rain to the north Gulf coast. With this trough, areas beyond the coastal mountains will stay out of much of the heavier precip. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2...Sun and Mon)... The pattern will stay very active to start the week. The first in the series of disturbances has cleared through most of the area. We were watching this very closely overnight to see how temperatures and visibilities responded to some warm air advection and the potential for blowing snow. There was enough warm air across the area to push most of Bristol Bay over to rain after a few hours of snow. There was also enough warm air to keep visibilities (so far) from dropping much below 2 miles along the coast of the YK-Delta. We used all of this information as the jumping off point for the forecast. As the next wave takes shape today and starts to trek from south to north across the area, expect a very similar day to Sat. Gusty northeast to southeast winds will resume as precipitation overspreads the area once again this afternoon and evening. There will still be some potential for blowing snow across the area, but the best bet remains along the coast of the YK-Delta. The biggest change to the overnight forecast was the issuance of a Winter Weather Advisory for snow and freezing rain across the Lower Kuskokwim. Warm air will move over the region just above the surface this morning into the afternoon. As it does so, it will create an environment where the precipitation can melt into liquid. But then, as it falls back through the below-freezing temperatures near the surface, it will have the potential to refreeze on contact. This, combined with several inches of snow, will lead to a hazardous weather day in the valley. By late Mon, most of the area will see drying as the system starts to move into the Bering. Another weaker system will queue up to move into Bristol Bay on Tue. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2...Sun and Mon)... The Bering will be divided into two weather patterns to start the week. First, over the Western Bering, expect strong northerly winds, snow showers, and cold temperatures. Out over the Eastern Bering, look for several low pressure systems spinning through the area. Each of these will bring rapidly shifting wind directions, warm air, and mixed precipitation. The interaction between this two Worms's will lead to a fairly healthy swath of storm-force (initially) winds driving from north to south from the Pribilof Islands down through Dutch Harbor. The duration and fetch under these winds will lead to seas climbing to near 30 feet. Conditions will generally improve late Mon as some weak ridging slides in from the east. But this will be short lived as another system slides into the Eastern Aleutians from the Gulf by Tue. In general, northerly flow will persist over the Western Bering. This will continue to allow cold air to trickle down from the Chukchi Sea/Bering Strait. && .LONG TERM FORECAST (Days 3 through 7)... The long-term forecast begins Monday night with an active pattern remaining across much of the forecast domain. The main feature is a large upper-level low centered south of the AKPEN and stretching from the central Aleutians and southern Bering through the Gulf. Multiple embedded shortwaves are pinwheeling around the main trough, with the first well-defined feature situated south of Kodiak Island, the second over the North Pacific well south of the AKPEN, and the third moving across the eastern Aleutians from the north. With the trough axis primarily over the AKPEN and two surface lows in the western Gulf, southcentral Alaska will be under the influence of a southerly fetch bringing a mild, subtropical airmass from the Pacific into the region. Moving through the week, both the deterministic guidance as well as their ensemble counterparts are in relatively good agreement in keeping this broad trough in place. The differences are in the timing and position of the shortwaves and the surface features. In terms of the big picture, the EC, NAM, and GFS all kick the low in the northern Gulf toward the Alaska Panhandle on Tuesday while the low in the southern Bering weakens and becomes absorbed into the main surface low near Kodiak Island. This low then weakens as it drifts southwest on Wednesday. Farther south, both the EC and GFS develop a new north Pacific low, moving it toward the Gulf on Thursday. Here the models diverge greatly, especially with the timing of the low, as the GFS brings the low into the northern Gulf by Thursday night while the EC delays the northward progression by a good 12 hours or so. Either way, it will remain fairly active across southcentral through next week with wind and rain along the coast and mixed precipitation for interior locations. Farther west, both the GFS and EC develop a ridge over eastern Russia, keeping a cold, northerly flow over the Bering. Guidance also develops a low west of Shemya midweek with a front swinging north across the Aleutians by late week. && .AFC WATCHES/WARNINGS/ADVISORIES...
