Alaska Extended Forecast Discussion NWS Weather Prediction Center College Park MD 313 PM EDT Mon Jul 08 2019 Valid 12Z Fri Jul 12 2019 - 12Z Tue Jul 16 2019 The anomalous upper level ridge that has been anchored over Alaska the better part of 2 weeks will continue weaken and shift a bit westward during the extended period. Model guidance, including the ensemble means, support this pattern although mid-level heights will be lower than they are currently. The broad low near the western Aleutians will slowly track east over the next week with multiples disturbances tracking through the Gulf of Alaska. The chosen blend for this forecast consisted of the CMC/GFS/ECMWF/GEFS mean/NAEFS mean/ECWMF mean with increased weighting of the means by the later periods. With the ridge weakening/shifting, temperatures across the state will in the 70s and 80s for much of the interior and a bit cooler near the coasts. A few daily temperature records may be tied or broken early in the period. Afternoon showers and storms may develop across portions of southern Alaska, and also across the central Aleutians as the Pacific low passes by the region.
