.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3: Tonight through Monday night)...
Generally expect precipitation to continue today, with improving conditions tomorrow. By late tomorrow through much of Sunday, however, a low will bring widespread precipitation and windy conditions. The biggest concern will, once again, be focused on area mountain passes, where temperatures could be cold enough to support appreciable snow accumulations over the course of the day on Sunday.
Diving into the details... an upper trough sliding east across Southcentral will continue to bring precipitation to Mainland Southcentral, with steadier precipitation for Prince William Sound, and showers from Kenai Peninsula north to Mat-Su. As the trough begins to transit out of the area from tonight through tomorrow, showers will become more infrequent before eventually tapering off.
Enjoy tomorrow's weather while you can, as stormier weather will soon be on the way by early Sunday morning. Forecast confidence is steadily growing that as a front in the Bering Sea moves over Southern Alaska, a weak surface low will develop near the southern tip of Kenai Peninsula and move east along the north Gulf coast.
Given the moisture associated with this front, most of Southcentral will likely see some precipitation with this system.
Still, the greatest amounts will likely be focused along the north Gulf coast, and likely along Susitna Valley due to upslope southwesterly flow. As the surface low strengthens, winds aloft will likely be strong enough to induce downsloping in Anchorage and parts of Kenai Peninsula, where precipitation will be lighter.
The biggest challenge with this storm will likely be precipitation type, especially at lower elevations. There's not much warm air aloft, so precipitation type will likely rely more on lower-level processes. Something to watch will be the coastal ridge that develops ahead of the low late Saturday into Sunday, which will likely kick up gusty southeasterly winds through Turnagain Arm, Knik Arm, and Copper River Valley. With these winds strengthening overnight and with increasing cloud cover associated with the approaching front, this may keep temperatures warm enough overnight that much of the precipitation will fall as rain, especially for Anchorage and Mat Valley. Still, given the time of year and the fact that we're not quite out of winter's grasp, it remains possible that some light snow accumulations may be squeezed out of this system in the morning before things melt and change to rain in the afternoon.

.SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS (Days 1 through 3)...
Currently, mid to low stratus linger across areas east of the Pribs and across the Southwest Mainland, including the Alaska Peninsula. To the west, the unseasonably strong North Pacific low we've been speaking to the last few days has moved north, with its low center now located between Attu Island and Adak - its cloud shield covering the western Bering, as far northeast as the Pribilof Islands. Gusts 50 to 60 mph will not be uncommon for the next 36 hours from Atka west and across the western Bering as the low moves north before losing some of its core strength. Shemya will receive the strongest winds, which are expected to gust up to 70 mph for a short period this evening. Precipitation may start as mixed before transitioning to all rain as warm air advection moves in. The low will slowly move east over the weekend. The leading front will bring a potential for blowing snow across the Pribilof Islands overnight tonight and the Aleutian Chain Saturday through early Sunday, before temperatures warm. The leading front will progress rapidly east bringing blowing snow conditions to the Kuskokwim Delta Saturday and Sunday as the front pushes inland. Winter weather products have been issued across the Delta for reduced visibilities in blowing snow over the period.
Despite the warm air advection in front of the low, cold air will wrap around the back of the low, allowing for higher instability and showery precipitation to form over the Bering as the low moves east. Looking ahead to next week, an Arctic trough dips into Southwest Alaska, potentially dropping low temperatures into the teens and single digits across the Southwest Mainland beginning Monday night. These temperatures combined with lingering precipitation from the strong low means widespread snowfall is possible Monday onward.
AB/JAR
.LONG TERM FORECAST (Days 4 through 7: Tuesday through Friday)...
A shift toward cooler and more unsettled weather is expected across much of Alaska through the upcoming week. A pattern dropping in from the north will bring colder air along with periods of snow showers across the interior and Alaska Range.
Meanwhile, a weakening but still impactful storm over the southern Bering sea will continue to create hazardous marine conditions, including gusty winds and steady precipitation across the Aleutians, Alaska Peninsula, and Southwest Alaska.
By early to mid next week, attention turns to Southcentral and Southeast Alaska as a developing system pulls in a deep surge of moisture. This will likely bring several days of rain and snow, with heavier snow totals possible across the Alaska Range and through higher elevation passes, along with increasing winds.
There is also a strong North Pacific low being monitored. While current projections keep it south of the state, any northward shift toward the Gulf of Alaska could lead to another round of impactful weather late next week.

AVIATION
PANC...Scattered rain showers will continue across Anchorage through tonight as a trough pivots across the area. A full array of ceilings currently exists from IFR heights up through VFR. Generally however, ceilings are expected to be in the MVFR range today before degradation to IFR CIGs overnight. Snow may mix in with rain tonight with any showers. Winds will remain light.
