SHORT TERM
/Through Tuesday night/ SEAK will see a break in between systems today, though scattered precipitation will continue through Tuesday. Winds for a majority of the panhandle will diminish through the day before steadily increasing as the next system moves in Wednesday. A ridge of high pressure is building over the panhandle, tightening the pressure gradient in the northern Lynn Canal region. This increased gradient is expected to bring high wind speeds and gusts potentially reaching 40 mph, prompting a small craft advisory until Tuesday night. The pressure field will relax as the low in the gulf approaches, bringing winds down. Temperatures remain close to normal, with lows slightly warmer and highs slightly lower than usual. The active weather pattern will continue through the week with the next front expected to reach the outer coast of the panhandle Wednesday.
LONG TERM
/Wednesday through Monday/ The first days of May are expected to be rather unsettled in terms of expected weather conditions courtesy of multiple low pressure systems and moist onshore flow from the Gulf. Cool wet weather pattern SE AK weather for the long range. Aloft, a broad upper low is expected to be in place across the Bering for the middle to end of the week, and then pivoting to the Gulf by next weekend and next Monday. 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. Low/front moving in early Wednesday with gale force winds developing along the Eastern AK Gulf. Some model differences on position and timing so but some more confidence details for the front position and reaching the NE Gulf / Northern panhandle first. 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 due to the earlier systems causing some rivers rises and the record and or record rainfall for the month of April. Periods of rain lasts into the weekend as the parent low reaches the Central AK Gulf but rates and overall coverage diminishes. Updated previous forecast with some more detail on front for Wednesday but overall 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
/Through 12z Wednesday/...
Predominate MVFR to IFR flight categories this morning as surface low weakens and dissipates inland with weak ridging moving in aloft, resulting in widespread CIGS AoB 2500ft and intermittent visibilities down to 2SM to 3SM across the panhandle.
Anticipating widespread precipitation with MVFR flight conditions or worse to continue through Tuesday morning. Shower coverage dissipates with gradual improvement to low-end VFR to upper-end MVFR flight conditions through 00z with CIGS AoB 5000ft, best flight conditions expected across the southern panhandle. A weak upper level wave will move into the far North Gulf Coast through Tuesday afternoon, keeping Yakutat locked into continual light precipitation, reduced visbys, marginal LLWS, and CIGS AoB 3000ft Tuesday night into Wednesday morning.
Main concern for today will be elevated winds for Skagway and Haines TAF sites with sustained winds up to 30kts and isolated gusts up to 40kts possible 18z through 00z this afternoon.
Elsewhere across the panhandle, winds should remain around 15kts or less, however, can't rule out a rogue gust up to 25kts.
MARINE
Outside: Onshore flow continues as a ridging pattern sets up for a near-gale force low moving through the gulf. Moderate to fresh breezes (11 to 21 knots) in the eastern gulf will steadily increase as the next front approaches. Wave heights remain around 7 ft with light southwesterly swell through Tuesday before increasing to upwards of 11 ft Wednesday.
Inside: Southwesterly winds will slowly increase and swing southerly through Tuesday into Wednesday as the next front approaches. Lynn Canal will be the exception to this, as they are expected to see heightened southerly strong breezes (22 to 27 kts)
with potential for gusts up to 45 kts through Tuesday morning, peaking through the afternoon. Winds will steadily decrease into Wednesday as the pressure gradient relaxes. Icy Strait winds are expected to flip easterly as onshore flow diminishes with the approaching front. Wave heights reach up to 4 ft in windiest areas, with channel entrances potentially seeing up to 6 ft.
AJK WATCHES/WARNINGS/ADVISORIES
PUBLIC...None.
