.AVIATION /07Z SATURDAY THROUGH WEDNESDAY/... Mainly clear skies will prevail through Saturday morning as high pressure sets up off the Mid-Atlantic coast. VFR clouds will increase west to east as a shortwave tracks across the northern periphery of this high pressure & its concurrent ridge Saturday afternoon/evening, bringing scattered showers with any flight restrictions looking to be brief and unlikely outside of any locally heavier showers. A few thunderstorms may develop across the Allegheny Plateau (KBFD/KJST) where the HREF mean MUCAPE values are around 100 J/kg. As precipitation progresses eastward, height rises and increasingly stable conditions will result in a downtrend in activity. As the shortwave exits our area during the evening, ridging will continue to build across the region, resulting in residual low-level moisture becoming trapped beneath a subsidence inversion. As a result, MVFR/IFR restrictions are expected to develop after 22Z-23Z Saturday across the Allegheny Plateau (KBFD/KJST), with lesser confidence in evening/overnight flight restrictions east of the Alleghenies due to downsloping flow and less antecedent moisture. Outlook... Sun-Tue...Mainly VFR. Patchy A.M. fog. Isolated P.M. shower or t-storm possible. Wed...Restrictions probable through Wednesday night with showers/storms along CFROPA. &&
