.AVIATION /01Z SATURDAY THROUGH WEDNESDAY/... VFR conditions will be commonplace through the holiday weekend. A building ridge aloft should limit any shower development to the Allegheny Front today. Otherwise, the forecast remains dry through Saturday. Some patchy fog development is possible on Saturday morning, mainly west of the TAF sites. By Sunday, an approaching area of disturbed weather lifts northward from the southeastern U.S. coast. While any impacts should stay well south of the area, some uptick in cloud cover is possible on Sunday. Initial northerly winds today will give way to south- southeasterlies this weekend as high pressure moves off the coast. Generally expecting VFR conditions through the long term period. However, each day will come with an increasing chance of afternoon/evening thunderstorms. This will bring a chance for restrictions at any of the terminals.
