Alaska Extended Forecast Discussion NWS Weather Prediction Center College Park MD 330 PM EDT Mon Apr 01 2019 Valid 12Z Fri Apr 05 2019 - 12Z Tue Apr 09 2019 Models and ensembles reasonably agree that a positively tilted upper trough across western and northern Alaska will deepen as it retrogrades into the Bering Sea. A cooling trend will bring below normal temperatures across much of northern Alaska as well as the higher elevations of southern Alaska, while above normal temperatures continue over southwestern Alaska. Active storm track will stay mainly south of Alaska through the medium range period. The consensus of the ensemble mean solutions agree reasonably well that old occluded cyclones will decay as they head toward the Gulf of Alaska. The next significant cyclone should likely impact the western Aleutians by early next week. The WPC product suite was primarily derived from a composite blend of the 00z bias-corrected NAEFS mean, 00z ECMWF ensemble mean, 00z ECMWF, 06z/12z GFS, and 12z GEFS mean. Precipitation will be mainly limited to parts of the Aleutians closer to the storm track, along with the Alaska Panhandle and southern coastal Alaska.
