Alaska Extended Forecast Discussion NWS Weather Prediction Center College Park MD 313 PM EDT Fri Mar 29 2019 Valid 12Z Tue Apr 02 2019 - 12Z Sat Apr 06 2019 Closed upper high will slowly retreat from mainland Alaska northwestward toward northeastern Russia later next week, maintaining troughing along 45N well south of the 49th state. Compact closed low currently over Southcentral will rotate clockwise over the AKPen then around/over the Alaska Range and back into the Gulf near Prince William Sound around Tue-Wed before lingering in the col between ridging over southwestern Canada and troughing over northwestern Canada and south of the Gulf. Main storm track will be well south of the area and blend of the 12Z FV3-GFS with the 00Z ECMWF added some details to the 06Z GEFS mean and 00Z ECMWF ensemble mean. This mostly kept any intrusion of lower heights over/east of the AK/Yukon border unlike some earlier runs of the GFS/ECMWF/Canadian--for now. Pattern would allow such an evolution to occur but predictability is low. Precipitation will be limited to parts of the Aleutians and increasingly over the Panhandle with onshore flow ahead of a system south of the Gulf late next week.
