Bermuda sfc high pressure remains over the wrn Atlantic Ocean with mid-upper level ridging over the ne CONUS through at least Sun. ECMWF starting to come more in line with the GFS model solution of tracking a low pressure system into the Southeast coast/Carolinas Fri night-Tue. Expect increasing clouds and wraparound moisture moving into areas along/south of the VA/NC border from the SE during the second half of Sat...with a return to more dismal rainy/cloudy conditions anticipated Sun-Tue. Thunderstorms will also be possible each aftn/evening during this time. Overall, the GFS has been much more aggressive than other long range models and have therefore trended the forecast twd a SuperBlend/WPC blend for POPs and a SuperBlend/WPC/MOS blend for sky cover. Low temps should remain fairly unchanged with readings in the 60s. High temps are expected to trend downward for Sat/Sun with highs in the lower 80s (low-mid 70s beaches), and even lower for Sun with highs in the 70s (upper 60s Atlantic beaches). && .AVIATION /12Z WEDNESDAY THROUGH SUNDAY/...
