Alaska Extended Forecast Discussion NWS Weather Prediction Center College Park MD 336 PM EDT Sat Apr 20 2019 Valid 12Z Wed Apr 24 2019 - 12Z Sun Apr 28 2019 ...Guidance/Predictability Assessment... The 12 UTC GFS/ECMWF now offer a reasonably similar solution Wedensday into early Thursday. The 12 UTC GFS trended strongly toward a solution in line with the 00/12 UTC ECMWF that suppresses a main Pacific storm track well to the south of the state. The 06 UTC GFS was the most recent GFS run to act as a much further north outlier in initialization sensitive model flow. Model and ensembles solutions diverge thereafter though, but the 00 UTC ECMWF ensemble mean and to a lesser extent 00/12 UTC ECMWF runs cluster better through late next week and maintain more WPC continuity than recent GFS/Canadian and GEFS/NAEFS runs. ...Weather Highlights... The pattern next week is not very active with a main storm track well south of the state, but seems highlighted by periodic/persistent but limited surface low formation and meandering into the northern Gulf of Alaska. Expect light to moderate rounds of daily precipitation will wrap inland into southern and southeastern sections of the state as enhanced over favored coastal terrain. These lows will be supported by a cooling mean upper closed low/trough over the Gulf whose position will be reinforced from upper trough energies digging from an unsettled southwest Alaska, the Alaskan peninsula and southern Alaskan Interior.
