Valid 12Z Fri 12 Jun 2026 - 12Z Tue 16 Jun 2026


...Stormy/Wet Gulf to SouthCentral Alaska by the weekend...


...Guidance Evaluation/Preferences...

Latest guidance solution clustering remains better than normal 
over the next week in a pattern with above normal predictability.
A favored model/ensemble mean/machine learning blend offers a 
solid forecast basis that mitigates much of the lingering smaller 
scale system differences as consistent with individual 
predictability. WPC product continuity is well maintained.

...Weather/Hazards Highlights...

The pattern will remain highlighted through this period by a slow
moving Arctic Ocean closed upper low/trough as slow moving closed
lows gradually lift/rotate from the North Pacific to over the 
Gulf of Alaska. Much of Mainland Alaska will be sandwiched in 
between in generally benign weather under a warming upper ridge.

Meanwhile, expect periods moderate rain/showers across the 
southern portion of the state with energies wrapping around the 
northern periphery of Pacific cyclones. Expect an emerging heavy 
rainfall threat from the weekend into early next week with 
wrapping moisture/enhanced inflow from SouthCentral Alaska to 
Kodiak Island given protracted proximity to a slow to 
lift/stalling Gulf of Alaska low and deepened triple-point low.
