Southeast Alaska Forecast Discussion National Weather Service Juneau AK 257 PM AKDT Fri May 10 2024

SHORT TERM
/Through Saturday night/ Quiet short range forecast today as the panhandle will be in between systems through Saturday night. Last night's system has completely cleared the panhandle and we are currently left with some clouds, onshore flow, and few light rain showers for the north. Some breezy southerly winds are still blowing through Skagway and northern Lynn, but those winds should continue to diminish into tonight.

Main concern for Saturday will be how cold overnight lows get across the north and if any fog will develop. For gardeners in areas around Hoonah, Gustavus, and the Chilkat Valley near Haines, lows Saturday morning look to dip into the mid to low 30s just enough for possible frost formation. so have decided to issues some frost advisories for those areas. For the Mendenhall Valley and Yakutat currently think that temps will just be warm enough to avoid frost, but there is still a chance clouds could break up enough to allow temperatures to drop overnight. Fog is also a possibility for many inner channel areas for Saturday morning due to the moist ground from yesterday and light winds. Thus patchy fog has been added to the forecast. Complicating the forecast is that if fog does develop, or clouds linger, temps may stay warm enough in the north to avoid frost altogether.

Into Saturday night, clouds and rain start to return and winds will be increasing as a new front moves in from the west. No atmospheric river influences this time so the rainfall should be mostly light.


LONG TERM
Wet and cool weather will continue for the long term period as low pressure continues to persist over the N gulf and southern Interior. The front will continue to impact the area bringing more rain to SE AK. Behind this front, we will see a break in precipitation before the next system starts to bring impacts to the area by late morning to early afternoon on Monday.
Behind this system, we will continue to see an active weather continue to impact the panhandle with more rain and winds as low pressures continue to work to the north and east from the N Pacific. The system that is expected to impact the area by midweek will need to be watched through the weekend as there is the potential for some heavier than normal rainfall for the S panhandle. Confidence in this idea is still low and will need to be watched for potential impacts. Getting into the extended long term, CPC guidance continues to show us still in a cooler than normal and wetter than normal pattern as we head into the middle to end of May.

AVIATION
Significant breaks in the largely elevated cloud deck will remain across the panhandle through Saturday before cloud cover begins building back in Saturday night through Sunday morning ahead of the next system. Largely MVFR and VFR conditions are likely to be interrupted in some locations Friday night through early Saturday morning as fog develops, producing sharp reductions in visibility and ceilings which could approach ground level. What fog does develop is likely to have largely dissipated by 9 AM Saturday morning.

MARINE
Mostly quiet marine forecast for the inner channels through Saturday featuring mostly lighter winds. Winds are not expected to start picking up in the inner channels until Saturday night with 20 kt southerlies for a wide area by late Saturday night. Slightly different story for the gulf waters where the incoming front will bring SE winds to 30 kt for most areas as early as Saturday. Seas will also be increasing with up to 15 ft seas for parts of the northern gulf by Saturday afternoon and night.
