Marine Weather and Tide Forecast for Adak, AK

.SHORT TERM FORECAST SOUTHWEST ALASKA AND BERING SEA/ALEUTIANS (Days 1 through 3)...

Weak ridging is present over the East Bering and the Southwest Alaska mainland, allowing for light winds and low chances for precipitation. Skies are clearing out over the mainland, but low stratus is present in the Alaska Peninsula and the Kuskokwim Delta. Meanwhile, two upper lows between a thin ridge in the Bering are pushing a "nose" shaped glob of precipitation and small craft winds eastward. The lows combine forces in the eastern Bering Tuesday afternoon and reinforce a surface low that continues moving eastward. The glob of precipitation and winds will impact the Eastern Aleutians and Alaska Peninsula through Wednesday. Gale force gap winds will also be present during the same time period for those regions. The low will drive moisture into the Southwest mainland, allowing for precipitation for all regions late Tuesday into Wednesday.

A weak ridge will follow the low, briefly decreasing precipitation chances and wind speeds first in the Bering Wednesday afternoon, then in the mainland Wednesday night into Thursday morning. There will still be enough moisture and lift in place in the mainland for scattered showers Wednesday afternoon.
This lull will not last long as another low will quickly push in from the west, driving a front through the Bering and into the mainland through Thursday afternoon. Once again, the mainland will see increased precipitation chances and wind speeds everywhere.
Looking a bit ahead shows that the aforementioned pattern may repeat itself with a ridge, then another low moving into Southwest Alaska over the weekend.

AVIATION

PANC...A low stratus deck (mostly in MVFR range) that developed earlier today appears to finally be eroding this afternoon with daytime heating, allowing ceilings to predominantly return to VFR range. Showers along with a gusty Turnagain Arm wind will return to the terminal by tomorrow afternoon. Cloud bases are expected to mostly remain in VFR range through tomorrow afternoon, but lower ceilings/visibilities down to MVFR will be possible at times in heavier rain showers.
