Alaska Extended Forecast Discussion National Weather Service College Park MD 516 PM EDT Thu Jun 5 2025 Valid 12Z Mon 09 Jun 2025 - 12Z Fri 13 Jun 2025 ...Guidance Evaluation/Preferences... The WPC Alaskan medium range pressures, winds, PoPs, and QPF were mainly derived from a composite blend of well clustered guidance of the 12 UTC GFS/ECMWF/UKMET/Canadian models early on, with some ensemble mean contribution from the EC/NAEFS late. Other grids were more reliant on the 19z NBM. This solution maintains reasonable product continuity in an active pattern with above average predictability. Guidance offers reasonably similar larger scale flow evolutions into next week with a cold low dropping out of AK, leading to building ridging across the interior, while a deep layer cyclone haunts the Aleutians and southern Bering Sea. ...Weather/Hazards Highlights... A concentrated area of heavier rainfall is expected along the southern coast and into the Southeast this weekend, but fades next week as the cyclone drops south and fills from late Sunday onward. Snows in the Brooks Range should also be on the decline during the medium range period. Some gales are expected with a low moving near the Aleutians next week. Rain should pick up across portions of the Aleutians and AK Peninsula as well.
