SHORT TERM
/through Tuesday night/...

Key Points: -Some breaks in the showers through the short term but with continued onshore flow, rain showers will continue to dot the landscape.
-Strong wind gusts upwards of 40 to 50 mph are likely in Skagway and the Klondike highway, some potential for 55 to 60 mph wind gusts.
-Above normal overnight low temps, below normal afternoon high temps.

Details: Surface low pressure is tracking eastward this Monday afternoon.
This low has been keeping the rainy and cloudy weather over the panhandle today. As this low moves east, the rain and rain showers will continue through Tuesday, though some breaks in the rain is likely, especially for those closer to the coast. The farther inland you are, the fewer the breaks.

As the previously mentioned area of low pressure exits the panhandle, a ridge of high pressure will build over Southeast.
This ridge will start increasing the pressure gradient in the northern Lynn Canal area. To the west of this expected ridge, will be a front that will tighten the pressure gradient even more as it approaches Tuesday into Tuesday evening. This tightening of the pressure field will cause the wind speeds and wind gusts to increase. The pressure field looks to relax Tuesday night, which would decrease the wind gust speeds.

For now, confidence is high that wind gusts will reach 40 to 50 mph but this weather pattern has produced wind gusts upwards of 55 to 60 mph in the past. Right now, there is about a 30% chance of wind gusts being at or above 55 mph. So there is some concern for high wind gusts near 60 mph but confidence is not high enough to issue an official product at this time. We'll continue to assess the weather data and update as needed.


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 Tuesday afternoon/...Marginal visual conditions will continue unabated for this short term period with instrument conditions at times. There's no getting around the fact that this is not the normal Spring flying weather SEAK is accustomed to experiencing. Freezing level is still well below normal and an ongoing issue for departing and arriving instrument traffic, as indicated indicated in PIREPS today. Mountain obscuration across all or Southeast Alaska will not be going away soon either. LLWS persists into the evening for the outer coast and is reflected in the Sitka and Klawock TAFs.

MARINE
Outside: For tonight, the recent gale force low will continue to track eastward. This puts wind direction in the gulf in an onshore pattern with the strongest winds, upwards of 25 to 30 kts, in the far southern outside zones. Lighter winds of 10 to 20 kts will be found elsewhere. Tuesday, another front will move west to east through the gulf, swinging winds to the south at 15 to 25 knots.

Seas are up to 10 to 15 feet, as of Monday afternoon, with a near 10 second swell in the southern gulf with those higher waves moving east, bringing wave heights down to to around 5 to 8 feet with a 2 to 4 second swell by Tuesday morning. As the next front approaches tomorrow, waves will slowly build to near 10 feet with a 3 to 4 second swell.

Inside: Inner channel marine concerns can be broken up into two sections: tonight in the south and tomorrow in the north.

For tonight, as the recent gale force low tracks east, the westerly winds will be rushing through the inner channels at a decent clip, upwards of 15 to 20 knots from a general west direction. But as the low exits the area, a ridge will build, which will swing winds to the south at around 10 to 15 knots.

For the north, as the ridge builds, it will tighten the pressure gradient in Lynn Canal. So southerly wind speeds upwards of 20 to 30 kts are likely beginning Tuesday morning and lasting through Tuesday evening. Afterward, wind speeds will decrease.

The next round of elevated winds in the inner channels will be late Wednesday into Thursday as the next gale force front moves through, increasing winds to 15 to 25 knots.
