Southeast Alaska Forecast Discussion National Weather Service Juneau AK 707 AM AKST Fri Nov 27 2020

SHORT TERM. Friday is off to a rather quiet start. The only issue is the presence of patchy fog across portions of the central and southern Panhandle, which is supported by the near calm winds and the decrease in cloudiness. Visibilities as low as 1 mile or less have been experienced across portions of the central and southern Panhandle. The ridge of high pressure that promoted this nicer weather will begin the push toward the east of the Panhandle Friday.

The models finally came into agreement for Friday's weakening low positioning. It should come ashore to the west of Yakutat Bay Friday afternoon. It will bring chances of light precipitation to primarily the northern Panhandle Friday afternoon into the night.

The short lull in active weather will quickly come to an end on Saturday when an approaching 965 mb storm force front approaches southeast Alaska. A tight pressure gradient will be present with this system across the region. Model winds at 925 mb are at around 70 kt over the Panhandle for Saturday. Winds are expected to gust up to 60 mph with sustained winds up to around 30 mph for Gulf coastal land areas from the Dixon Entrance to Salisbury Sound as well as the Juneau area. A High Wind Watch is in effect for these areas. Sustained gales up to potential storm force winds with higher gusts are expected along the outer Gulf coast on Saturday. It will remain rather breezy behind the front for about 12 to 18 hours as the pressure gradient relaxes.

The Saturday system will also be a wet one with heavy precipitation anticipated for much of southeast Alaska with enhanced PoPs and QPF values across the area. The precipitation will primarily be liquid for much of the Panhandle. Enough cold air will be in place for the Haines Highway and Klondike Highway areas to stay primarily snow. For the Klondike Highway, around 1 inch of snow is possible for Friday night and up to 6 inches during the day on Saturday. For the Haines Highway to the Canadian border crossing, around 1 to 2 inches of snow is possible Friday night and around 6 to 8 inches on Saturday.

It looks like storm systems will continue to approach the southeast Alaska in quick succession for the foreseeable future. The onslaught continues.

LONG TERM. /Sunday through Friday night/ . The first of three strong fronts laden with a low of PW will be over Southeast Alaska at the start of this extended range forecast period. The others will impact the region on Monday night through Thursday morning and then Thursday night through Friday afternoon. Some locations may see a break from the relentless precipitation Sunday night and Monday morning but after that. anybody got an ark handy? The front that will being to affect SEAK Monday night has indications that it may be a training event with a wave working its way along the frontal boundary, causing it to waiver north and south across the Panhandle before giving way to the follow on low and associated front Thursday night. At present, locations north of Cape Ommaney and Frederick Sound will received the majority of this precipitation. Low level onshore flow and temperatures as well as mid and upper level thickness values all point to these fronts being predominantly rain makers (vice snow) for all of Southeast Alaska except possibly the far northern inner channels - Skagway, Haines, and the associated highways. By Tuesday night, the only potential left for snow will be at higher elevations along the highways.

The eastern Gulf and inner channels will get a break from the gales and small craft conditions that have been quite common for the past several days. until Monday night. At that time, the next high end gale force (possibly storm force) front will push across the eastern Gulf. Those winds winds may last as long as Wednesday night as wave rides north along the front and re-invigorates the front. At least one long range mode is suggesting that more high end gales are possible Thursday night, but we'll see what happens.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. 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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
