Alaska Extended Forecast Discussion NWS Weather Prediction Center College Park MD 533 PM EDT Sat Jun 11 2022 Valid 12Z Wed Jun 15 2022 - 12Z Sun Jun 19 2022 ...Overview and Guidance Evaluation/Predictability Assessment... The guidance shows rather good agreement, both amongst the deterministic and ensemble mean guidance, which also resemble one another. There are some minor details such as the ECMWF being stronger with a cold low moving towards the AK Panhandle early on, and the strength of a system aloft and at the surface impacting the Aleutians late next week. Used a blend of the 12z GFS, 12z UKMET, 12z ECMWF, 12z Canadian early on for the pressures, fronts, winds, and 500 hPa heights -- which should take care of the above issues -- before shifting slowly in the direction of the 00z ECMWF and 00z NAEFS ensemble means once we get past the end of the UKMET's run. This solution kept reasonable continuity. ...Weather and Hazard Highlights... An upper low scrapes northwest Alaska, and with moisture available to stream northward from the Gulf towards this system, much of central and southern Alaska can expect showers throughout much of next week, with portions of northern AK overall the least cloudy. Some local enhancement is possible across favored terrain. A deep low moves near the Aleutians/AK Peninsula later next week and offers a maritime threat, with some increasing rain chances into the Aleutians and AK Panhandle and with gale-force winds with rain amounts of 2-4" of rain expected. Interior and Southern AK should remain mild to warm, with cooler readings in the usual spots along the coast, the Aleutians, and the North Slope. Roth No significant hazards are expected over Alaska during this forecast period.
