Southeast Alaska Forecast Discussion National Weather Service Juneau AK 553 AM AKST Wed Jan 27 2021
SHORT TERM. /Through Thu night/ Strong northerly outflow continues this morning with gale force winds blowing down Lynn Canal, Stephens Passage, and out of Taku Inlet this morning. Gusty winds have also been seen out of Cross Sound, and down Chatham Strait. The Taku winds have been active in downtown Juneau and Douglas as well overnight.
The main story for the short range is continued outflow winds today that will diminish into Thu as the Yukon high weakens and moves into northern BC. Not many changes to the forecast with most things staying on track for winds. The wind chill advisory for White Pass continues until midnight tonight. Observed wind chills have reached -32 overnight at White Pass. The one notable change was a warm up of temperatures in areas where there was wind due to mixing not allowing the overnight inversion to set up.
As the outflow diminishing Thu focus shifts to the front coming in from the west Thu into Thu night. Winds along it in the central and northern gulf have been increased to gale force as the system is trending stronger in recent guidance. Snow will also be starting up at Yakutat Thu with advisory level snow rates expected. Snow totals will likely reach about 6 inches for the period from Thu morning through late Thu night. The rest of the outer coast will likely see precip start up Thu night. Precip could travel farther inland then that, but confidence is rather low once you get into the inner channels due to some easterly outflow still present. Conditions will be cold enough that most precip will fall as snow in most places with light accumulation expected through late Thu night.
LONG TERM. With an upper low firmly entrenched over the western Gulf of Alaska and our heavy-duty ridge responsible for all of our dry and cold weather this week shoved into western Canada, energy associated with the North Pacific storm track jets forward to the south of us. This effectively slows the threatening surface front offshore, all but preventing moisture incursion through the Inner Channels. Not only does the action to the south hinder forward progress of the precipitation, but it also helps preserve the cold air and very low freezing levels throughout most of the Panhandle Friday into the early weekend. The bulk of precipitation then should fall as snow uncharacteristically for coastal communities and the south, rather than the typically snowier northern Inner Channels.
This pattern persists later into the weekend, except that the lowest heights migrate to the south of us rather than the west. Cold continues, yes. But chances of precipitation should fall as we head into early next week with increasing offshore flow. With this in mind, there should be periods of outflow winds, stronger in the northern Inner Channels, and much of the time period, northerly winds dominate.
Sometime early next week, a North Pacific storm well to our west begins to accelerate the train of synoptic features--including ridges and troughs--to the east once again. Thus, a ridge rebuilds early next week, but just as quickly folds into Canada as frontal action sweeps into the Gulf of Alaska. Therefore, precipitation pushes back into the Panhandle. For now, we see little reason to believe that much of it will fall as snow. But temperature confidence by mid-next week falls, and thus p-type as well.
