Alaska Extended Forecast Discussion NWS Weather Prediction Center College Park MD 208 PM EDT Sun Apr 21 2019 Valid 12Z Thu Apr 25 2019 - 12Z Mon Apr 29 2019 ...Guidance/Predictability Assessment and Weather Highlights... The weather pattern is not very active over the next week with main storm tracks well south and well west of the state. Moderate surface low developments over the northern Gulf of Alaska will support modest periods of precipitation inland into southern/southeastern Alaska as enhanced over favored coastal terrain. These lows will be supported by a mean Gulf of Alaska upper closed low/trough. The WPC Alaskan medium range product suite was mainly derived from a blend of the 00 UTC ECMWF ensemble mean and to a lesser extent the compatable 00 UTC ECMWF. This blend maintains good WPC continuity and offers detail consistent with a pattern with slightly below normal overall predictability. Recent GFS/GEFS runs have not offered stellar continuity, but latest 12 UTC GFS/GEFS runs have trended from outlier solutions to at least more in line with that preferred by WPC.
