LONG TERM FORECAST (Days 4 through 7 - Saturday through Tuesday)

Upper-level troughing centered over the northern Gulf of Alaska will extend south into the Northern Pacific, with multiple shortwaves rotating around the trough. Some model differences in the position and track of resulting surface lows lifting into the Gulf will continue to keep the precipitation forecast confidence below average for the long term. A lean towards the GFS ensembles brings a shortwave over the Western Aleutians by mid to late week with a shot of colder temperatures dropping southward out of Northeast Russia and into the western Bering. Strong northwesterly flow and cold air advection will lead to the potential for strong gap winds across the Barren Islands and Southern Alaska Peninsula. While forecast confidence is low with regard to where surface features and precipitation ultimately develop, forecast confidence is high that both Southwest and Southcentral Alaska will continue to see below normal temperatures through the end of this week.
