Alaska Extended Forecast Discussion NWS Weather Prediction Center College Park MD 350 PM EDT Sun Apr 07 2019 Valid 12Z Thu Apr 11 2019 - 12Z Mon Apr 15 2019 Troughing well southwest of the Aleutians will lift northeastward into the Bering as ridging builds ahead of it into the Gulf and eventually into the Beaufort Sea. Models/ensembles still struggle with the specifics of how the system comes together with a trend toward less consolidation. However, still expect the parent low to linger for a couple days as the triple point low and frontal system push through the Gulf and into the Panhandle. This will spread rain/snow to the AKPen, Southcentral, and points eastward. The North Slope and eastern interior will stay largely quiet and mostly precipitation-free. Though the ensemble means were relatively close to one another, the deterministic runs were not, but added details via the 12Z FV3-GFS and 00Z ECMWF/Canadian/UKMET as appropriate--though none exhibited a preferred evolution. Next system of interest would be over the weekend into next week as a system heads out of the central Pacific and along or just across the Aleutians. 12Z GFS offered the closest track to the largest ensemble clustering, though the 00Z ECMWF/Canadian were not too far from that consensus.
