Alaska Extended Forecast Discussion NWS Weather Prediction Center College Park MD 540 PM EDT Tue Jun 14 2022 Valid 12Z Sat Jun 18 2022 - 12Z Wed Jun 22 2022 ...Overview and Guidance Evaluation/Predictability Assessment... The guidance shows reasonable agreement, both amongst the deterministic and ensemble mean guidance, which also resemble one another. The guidance agrees on the track of the mature/weakening cyclone moving from the AK Peninsula,towards the AK Panhandle between late this weekend and early next week. Used a blend of the 12z GFS, 12z UKMET, 12z ECMWF, and 12z Canadian early on for the pressures, fronts, winds, and 500 hPa heights before shifting slowly in the direction of the 00z ECMWF ensemble mean 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... Shortwaves brushing by northwest Alaska reinforce a front across north and northwest AK which remains quasi-stationary until an occluded cyclone approaches late this weekend into early next week, lifting it into the Arctic Ocean. Moisture is available to stream northward from the Gulf within the southwest flow aloft, much of eastern and southern Alaska can expect showers from late this week into next Monday. Some local enhancement is possible across favored terrain. A deep low moves from the AK Peninsula towards the AK Panhandle this weekend into early next week with a decreasing maritime threat with time other than previously generated swell. Overall, southern and eastern should be wettest this period, though drying is noted early next week. Better chances for clearing skies are in northern portions of the state and early next week down south. 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.
