Alaska Extended Forecast Discussion NWS Weather Prediction Center College Park MD 618 PM EDT Fri Jun 26 2020 Valid 12Z Tue Jun 30 2020 - 12Z Sat Jul 04 2020 ...Overview and Weather/Hazard Highlights... A series of organized systems from the Bering Sea should move east across mainland AK along with slowly weakening surface fronts Tue/Wed and generate unsettled/showery conditions with passage. Elsewhere, a more deepened low pressure system crossing the North Pacific is forecast to work from the southern to eastern Bering Sea Wed-Fri as a lead associated front sweeps east across the Aleutians toward Southwest AK. A second deepened low may follow quickly behind it into the southern Bering Sea next Fri/Sat. Showery conditions along with gusty winds should accompany these system across the Aleutians, and perhaps into portions of the AK Peninsula as a warming downstream upper ridge slowly builds in advance up into AK. ...Guidance/Predictability Assessment... The WPC Alaskan medium range product for Tue-Thu (Days 4-6) was made from a composite blend of well clustered solutions from the 12 UTC GFS/ECMWF and GEFS/ECMWF ensemble means along with the 19 UTC National Blend of Models. Opted to use the still reasonably well clustered ECMWF and ensemble means Days 7/8 (next Fri-Sat). This maintains decent WPC continuity.
