Area forecast discussion, Nov 20, 4:53 AM AKST, 10 hours 28 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 453 AM AKST Tue Nov 20 2018 .ANALYSIS AND UPPER LEVELS... A vertically stacked, occluding low spins at the center of a long wave trough that encompasses a vast majority of the Gulf of Alaska. Cooler, drier air is wrapping around the low which is enhancing the occlusion process. Scattered showers are seen on radar pushing across the Gulf Coast rotating around the top of the surface low. Clearer skies are present further inland leading rapid surface cooling and fog development over portions of the Copper River Basin, the Anchorage Bowl, and the Western Kenai Peninsula. A second long wave trough is over western mainland Alaska and the eastern Aleutians. This trough stems from a vertically stacked low north of Mekoryuk Island. Behind the trough, northerly flow is advecting cold air over the Bering and AK-PEN. At the surface, a shortwave trough is embedded within the flow of the larger, main western trough. A north-south oriented front sits over the AK-PEN and eastern Aleutians. High pressure is building quickly over the western Bering. && .MODEL DISCUSSION... Models are again in decent agreement this morning with the development and progression of the synoptic level features. There are some differences by Wednesday/Thursday regarding a broad trough over the Gulf and how several weak surface lows interact with each other, though the only differences in the sensible weather revolve around the magnitude of the northwesterly outflow winds coming out of Kamishak Bay. && .AVIATION... PANC...Clearing skies overnight has lead to the enhancement of a surface inversion and consequently fog development over the Knik Arm, which has advected east over the terminal. The fog/stratus will do the typical ebb and flow through the morning before slowly burning off around noon, though low stratus may linger in the area through the afternoon. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)... A fairly well organized low over the Gulf drifts to the eastern Gulf coast tonight then weakens and retrogrades west Wednesday. A weak deformation zone with rain and snow over the western Susitna Valley will slowly weaken through today. Locations along the North Gulf Coast will see the lions share of precipitation (mainly showers) with the low skirting the northern Gulf through Wednesday. Inland areas, except for the aforementioned western Susitna Valley, will generally see a mixed showers through today, with a nudge toward snow snow will slightly cooler air. Showers will diminish over most inland areas tonight and Wednesday. Patchy fog is expected in may areas this morning across the Cook Inlet Region as well as the MAT-SU and Anchorage Bowl. May see a recurrence tonight, but not on such a large scale. Westerly gales over the offshore Gulf waters will diminish through today. Winds over the northern marine coastal waters will see some increase today and tonight and may approach gales, but should be on a weakening trend Wednesday morning. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3)... Two weak fronts keep higher chances for snow in the forecast through Wednesday morning, then a cold dry pattern sets up through Thursday night. The first front moves inland across Bristol Bay this morning bringing light snow as it moves east across the Aleutian Range this afternoon. At the same time, a second low dives south along the coast crossing over the Alaska Peninsula tonight. Only trace accumulations are expected as dynamics remain weak for these two systems. Patchy fog across the region is expected through Wednesday morning then winds become northerly on the backside of the low pulling a cold air mass across the region. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3)... Low pressure along the eastern Bering will advect a colder air mass toward the Alaska Peninsula bringing snow and rain showers through Wednesday afternoon; then the upper level low moves southeast to the Gulf. To the west, the next strong front moves to the western Aleutians late tonight bringing max gale force easterly winds and rain along the frontal boundary. This front begins to weaken on takes a slow northeast track on Wednesday. However, a re-enforcing North Pacific low will kick this system into motion Wednesday night with gale force winds and rain spreading across to the Alaska Peninsula and Pribilof Islands by Thursday night. && .LONG TERM FORECAST (Days 4 through 7: Friday through Monday)... The long-term forecast remains an uncertain one during the Friday through Monday time frame. While all the models have a good handle on day 4 with seasonably cold and quiet weather across mainland Alaska, the uncertainty develops behind where a strong low tracking eastward along the Aleutians goes, how strong it gets, and how quickly it moves. Each of the models has a different solution to this. As a new low over the north Pacific approaches it, the low is expected to deepen as the two lows merge. The GFS and EC both keep the low drifting eastward, while the Canadian tracks it faster into the Gulf. In addition, there is significant uncertainty by Sunday and Monday as to exactly where the cold air sets up, with the GFS by far the warmest, the Canadian the coldest, and the EC in the middle. Most of the models agree the seasonably cold and quiet weather for Thanksgiving and Friday turns warmer and wetter by the weekend over Southern mainland Alaska, but how much so remains a question with significant uncertainty. && .AFC WATCHES/WARNINGS/ADVISORIES...
