Alaska Extended Forecast Discussion NWS Weather Prediction Center College Park MD 545 PM EDT Fri Apr 22 2022 Valid 12Z Tue Apr 26 2022 - 12Z Sat Apr 30 2022 ...Guidance/Predictability Assessment... The WPC Alaskan medium range product suite was mainly derived from a 12 UTC GFS/ECMWF/UKMET/Canadian composite for Day 4/Tue that increasingly transitions Wednesday into Thursday to completely the more compatible 12 UTC GEFS/ECMWF ensemble means by days 7/8 amid growing forecast spread and uncertainty. While model system variances are less than stellar even early into the medium range time scales, there are some predictable components to justify inclusion of model input for at least through midweek. The resultant blended solution along with the 19 UTC NBM maintains reasonable WPC product continuity. ...Overview Weather/Hazard Highlights... Lingering low pressure systems over the eastern Gulf of Alaska next week will continue some light to locally terrain enhanced moderate precipitation across the southern Coast, but mainly the Panhandle. Activity should wane with time as the lows weaken and lose influence. Moderate precipitation will also progress across the Aleutians and the Alaskan Peninsula/Kodiak Island with a couple of frontal systems/main lows through the period and as amplified upper low/troughing focus gradually transitions outward from the southern Bering Sea to the western Gulf of Alaska. Much of the Mainland should remain dry next week. However, uncertain but potentially amplified upper impulse/trough developments and terrain may favor some very localized enhanced snows for northern Alaska/the Interior. Schichtel Hazards: No significant hazards are expected over Alaska during this forecast period.
