Southeast Alaska Forecast Discussion National Weather Service Juneau AK 635 AM AKDT Sat Oct 23 2021

SHORT TERM. /Through Sunday night/A strong gale force low in the central gulf, arguably farther west than progged 36 hours ago lifts west northwest into the western gulf through this afternoon. High pressure then begins to build across the Coast Mountains this afternoon and then shifts into northwest Canada tonight. Sunday, a powerful low well south of Haida Gwaii presses into Vancouver Island. And this will result in northerly gradient through the Inner Channels Sunday into Sunday night.

A trailing front extending from the north central gulf into the central and southern Panhandle yielded some strong winds and gales overnight. Strong winds are dying around Sitka, but Saturday will still be a relatively breezy day across the central and southern Inner Channels. Showers, too lift northward with the front. What we watch today is a trowel of colder air lifting northeastward behind the front. Mid-level lapse rates rise to 7 C/km plus; and vorticity aloft passing across the area in southerly flow tonight may be sufficient to produce lightning in heavier showers. We feel the dynamics may be strong enough to last into this evening.

Showers begin to dissipate especially across the Inner Channels as they retreat to the coast late Saturday night into Sunday morning. Stability increases as well, ending the thunderstorm threat as southerlies transition to northerlies across the region. With clearing and increasing stability there is a threat of patchy fog developing Sunday morning and again Sunday night/Monday morning. But while northerlies will not be strong, 20 kt winds through the Inner Channels could be sufficient mixing to inhibit its formation in all but a few very sheltered locations. But for now, we keep it in the forecast for all but Downtown Juneau/Douglas Monday night.

There is a weak Taku set-up that may occur late Sunday. As cull sets up over the central Panhandle from BC during this time. With presumably clearer skies and more cold air forming across the Canadian border, we may have more of a chance of Taku winds than the last couple of opportunities. Also, the fact that ingredients set up during the afternoon of Sunday, when mixing is prime, raises confidence. Because of this, we did add some gusts to 40 mph Sunday night.

We did warm temperatures a little, especially across the south Sunday as a weak thermal trough is enhanced from downsloping. There could be some snow mixed in with isolated showers along the Haines Highway or even in some other northern Panhandle communities, but 850 mb temperatures are not bullish on this idea. all in all, Sunday appears to be a beautiful day across much of the Panhandle with temperatures warming between 45 and 50 degrees. Lows fall successively cooler though from this morning to Sunday morning to Monday morning. By Monday morning, widespread 30s are expected across the Inner Channels with some upper 20s in parts of the northern Panhandle.

LONG TERM. / Monday through Saturday as of 10 pm Friday / Flow pattern aloft for the weekend and next week looks like the following. An upper-level trough over the eastern Gulf with a closed 500 Mb low West of Vancouver Island Monday lifts into the panhandle Monday evening. A second trough moves into the eastern Gulf of Alaska and then lifts onshore across the panhandle Wednesday. The end of the week is more of the flow becoming more SW to Westerly, while a stronger low is suggested by model solutions to track into the Gulf at the end of the week and next weekend.

The weakening front/trough associated with the Vancouver Island low moves into the southern panhandle and spreads light precipitation in later Monday evening. A new surface low will track across the Southern Gulf of Alaska and to the southeastern portion of the Gulf Tuesday evening. The upper-level flow will steer the low and associated precipitation through Southeast Alaska and into Canada. The westerly flow will keep the onshore flow for the end of the week. Looking at the long-range pattern, and believe in the fair model agreement that a well-organized front will sweep in to the central Gulf right before the weekend.

Monday's weather starts with a break in the rainy weather, as much of the forecast area has a reprieve from the typical fall rains. Cooler temps are anticipated in the northern sections Monday and Tuesday mornings. Kept the area of patchy that was in the forecast for early Monday.

Overall no significant weather feature is expected for the Eastern Gulf of Alaska and Southeast Alaska until the end of the week, where a big system may be making an appearance. Confidence is average for the extended forecast.

AJK WATCHES/WARNINGS/ADVISORIES. PUBLIC . Strong Wind until 7 AM AKDT this morning for AKZ023-026. MARINE . Gale Warning for PKZ036-043-051-052-310. Small Craft Advisory for PKZ021-022-031>035-041-042-053.
