Alaska Extended Forecast Discussion NWS Weather Prediction Center College Park MD 357 PM EDT Tue Apr 02 2019 Valid 12Z Sat Apr 06 2019 - 12Z Wed Apr 10 2019 Models and ensembles generally agree that a positively tilted upper trough across western and northern Alaska will deepen as it retrogrades into the Bering Sea. Smaller scale details have been run to run inconsistent, but overall this favors a cooling trend for this medium range period across much of northern and interior Alaska as a front settles down toward southern Alaska. Meanwhile, an active storm track will stay mainly south of Alaska through the next week. A consensus of guidance solutions show that the main occluded cyclones will decay as they head over the Gulf of Alaska. The threat also exists for a significant cyclone to impact the western Aleutians by early next week. The WPC product suite was primarily derived from a composite blend of the latest GFS/ECMWF and GEFS/ECMWF ensemble means Saturday through Monday and then just the ensemble means day 7/8 in a period of quickly increasing guidance forecast spread and uncertainty. Heavier precipitation will be mainly limited to the Aleutians closer to the storm track, along with into the Alaska Panhandle and southern coastal Alaska.
