Southeast Alaska Forecast Discussion National Weather Service Juneau AK 548 AM AKST Thu Feb 20 2020

SHORT TERM. Upper level jet with a core of 140 kt aimed at panhandle drifts southward through the day and weakens. The jet had been driving the short wave supporting the surface front across the gulf to the panhandle. The front moving through during the day will support strong gusty winds from 40 to 60 mph. Have posted a Warning for the Yakutat area this morning, and for the Juneau area this afternoon. Most of the remainder of the panhandle will have strong wind headlines this afternoon or evening.

Winds are expected to diminish tonight, though along the northern canal and Skagway regions the stronger winds will continue through tonight.

Precip starting as snow in the Yakutat area this morning but should be shifting over to rain in the next couple of hours. Across the panhandle, rain or a mix possible to start, that should also transition to rain. Exception to the rain will be higher elevations, where it should be snow. Have continued the Winter Storm warning for heavy snow, and blowing snow in gusty winds through the White Pass region of the Klondike Highway.

Calmer weather for Friday, with onshore flow and fairly widespread showers. The cooler airmass will begin to move into the region in earnest Friday so showers may be snow or a mix by later in the day.

LONG TERM. /Saturday through Thursday as of 10 pm Wednesday/ Rather complex and shifting pattern for the long range forecast. Saturday starts out with a broad upper trough over Alaska with the jet stream flowing through the northern Pacific into the Southern Panhandle and Western BC. A small split flow pattern develops in the jet W of Haida Gwaii Sat night with the northern branch going over the northern panhandle and the stronger southern branch heading into Vancouver Island. Feature proves to be very transient as a ridge builds over the AK Peninsula then moves over the Gulf Sun and Mon. At the surface, colder weather and snow showers will be the norm over the weekend and early next week from both the W onshore flow and some weak lows moving through as a colder air mass moves in from the west. 850 mb temp forecast to be negative 6 to negative 9C over the panhandle during this time but the lower levels will be modified from its time spent over the gulf before it gets here. Some snow accumulation is possible during this time with varying amounts due to where the heavier showers set up.

Beyond this point, guidance diverges past Mon on where the ridge in the gulf early next week then moves with solutions ranging from a cut off high over eastern Russia to more attached ridge extending from the eastern gulf to the Arctic. Resulting weather forecast is rather uncertain with differences in the upper ridge position effecting how much cold air makes it to the panhandle from the N late next week, and the timing of a strong front coming up from the south at the same time. Currently, the GFS and ECMWF are at odds with the GFS gunning for a weaker warmer Yukon high with the front moving in by Tue, while the ECMWF favors more substantial cold air that completely blocks any fronts from the gulf making it to the panhandle until at least Thu. Ensemble and WPC solutions have been favoring the warmer of the two possibilities though they have been trending slower with the front coming up from the south over the last few days. Favored the ensemble and WPC for updates today.

AVIATION. Strong winds due to the frontal band. Expect some widespread turbulence near terrain in the really strong winds. Handful of locations also favorable to low level wind shear. The moisture and lower freezing levels, there may be localized icing to day as well. Situation improves after the front goes through for the wind items, but Marginal clouds ( or lower) likely to persist.

MARINE. Storm force winds along the outer coast and gales and small craft winds for the inner channels as the incoming front moves through the panhandle. Seas in the mid to upper teens following the main frontal band.

AJK Watches/Warnings/Advisories. PUBLIC . Strong Wind from noon AKST today through this evening for AKZ026- 027. High Wind Warning from noon today to 6 PM AKST this evening for AKZ025.
