SHORT TERM
A near-gale force frontal system has moved into the eastern gulf early this morning and will bring precipitation and high winds to the panhandle through today. Up to 35 knot winds are expected in the eastern Gulf and channel entrances as the front moves through the area, with 25 to 30 knot winds possible through the inner channels and southern coastal land areas. Winds diminish through tonight as the low moves inland and the pressure gradient relaxes before the next system enters the gulf tomorrow. Total rainfall of 1 to 2 inches is expected for a majority of SEAK with peak values in southeastern regions. Ketchikan has already received 1.2 inches of rainfall within the past 6 hours. Temperatures remain near normal with lows in the lower 40s and highs in the lower 50s.
The active weather pattern will continue through the week with the next front expected to reach the outer coast of the panhandle by Wednesday.
LONG TERM
/Tuesday through Sunday/ SE AK weather for the long range will continue to be a cool wet pattern. Upper levels keeping either a low or trough over the region, mainly advancing from a main low anchored over the Bering.
While there are short periods of ridging tracking in there are just no foreseeable long or substantial breaks in the next week, and from CPC outlook likely the next two weeks. Tuesday rain showers are one of those few times that breaks in precip may occur as the previous low / front moves inland and a ridge moves in.
Tightening pressure gradient increasing NS channel winds. Onshore flow keeps some shower activity Tuesday with next low/front moving in that evening. For now parent low stays further west so winds along this front reaching gale force. Still some model differences on position and timing so not enough confidence to fully commit on details. EFI puts more heavy precip into the region with long fetch of moisture from the south. Hydrology concerns with this next batch of heavy rain, especially if the earlier system rivers rises remain elevated. Rain lasts into the weekend as the parent low reaches the Central AK Gulf. Little change to previous forecast as it either remained in line with new model runs or there is still enough spread in operational model that a national blend still covers the gist of the long range.
AVIATION
Mixed bag of VFR down to IFR flight conditions this morning as a low in the eastern Gulf extends a front into coastal and interior SEAK, overspreading showers, elevated winds, and LLWS across the panhandle through Monday. Gradual improvement through mid morning post-front to widespread predominate MVFR to low-end VFR flight conditions with CIGS AoB 5000ft and intermittent vsbys down to 3SM within heaviest showers, continuing through Monday evening as the aforementioned low pushes inland. Winds will remain elevated across the southern panhandle TAF sites and for the usual suspects like Haines and Skagway through Monday afternoon with sustained winds up to 25kts and isolated gusts up to 35kts.
Main aviation concern for today will be flight conditions for coastal and southern panhandle TAF sites, with southeasterly LLWS turning southwesterly around 1000 to 2000ft near 35kts through Monday afternoon as front pushes inland.
MARINE
Outside: A near-gale force front will bring sustained near gale force winds (28 to 33 kts) and up to 17 ft seas with a southwesterly swell today. The majority of the gulf will see between 10 to 14 ft seas through tonight, with the highest wave heights impacting the outer coastline of Baranof Island. Winds in the northern gulf will switch from easterly to westerly as the low moves onshore.
Inside: NS oriented inner channels will see up to fresh breezes (17 to 21 kts) sustained as the near-gale force front moves over the area through tonight. Channel entrances are expected to see sustained strong breezes (22 to 27 kts) with gusts up to 30 kts.
The Easterly winds in Icy Strait are expected to switch westerly as ridging moves over the panhandle into Tuesday morning, with highest speeds in Cross Sound. Light northerly winds in Lynn Canal will switch southerly through Monday morning and will steadily increase to fresh to strong breezes (17 to 27 kts) through Tuesday as the approaching front causes the gradient to tighten. Wave heights peak at 4 ft for a majority of the channels, while channel entrances may see up to 10 ft seas through this morning.
