Alaska Extended Forecast Discussion NWS Weather Prediction Center College Park MD 321 PM EDT Sat Nov 02 2019 Valid 12Z Wed Nov 06 2019 - 12Z Sun Nov 10 2019 An upper high will center near the Bering Strait next Wednesday through the weekend, favoring troughing around its periphery with a storm track beneath the Aleutians and into/south of the Gulf. The models/ensembles were in good agreement through the period on the longwave pattern but continued to struggle with the smaller wavelength features. Overall, there was still little change to the surface fronts from 24 hrs ago with an emphasis on the ensembles by the end of next week. A varying multi-model/ensemble blend among the 12Z GFS/00Z ECMWF and the 06Z GEFS mean/00Z ECMWF ensemble mean was used as a starting point. Trended toward more weight to the ECMWF with the ECMWF ensemble mean as the GFS drifted from that better clustering. Rain/snow should mostly be confined to coastal and near-inland areas from the Aleutians and across Kodiak Island into the Panhandle as systems track beneath the Arctic drape across British Columbia. Temperatures will remain near to above average over much of the state, especially the North Slope and southwestern Alaska/Southcentral. The exception will be over the eastern interior beneath high pressure and over the Panhandle where the slipping Canadian high will funnel in cooler temperatures on easterly flow.
