.AVIATION /12Z SUNDAY THROUGH THURSDAY/... Widespread VFR (VSBYS and CIGS) noted across much of PA this morning with variable amounts of mid and high level clouds drifting ESE across the Northern 2/3rds of the state. Convergence axis between low level south/southwesterly flow was located just to the west/NW of Chesapeake Bay and was leading to the formation of an area of MVFR stratocu clouds that was drifting northeast over portions of the Lower Susq Valley, mainly to the east of RT 15. This area of strato cu will advect further North/Northeast and impact KMDT, KCXY and KLNS through the late morning hours, with CIGS AOB 2000 FT AGL at times. Tempo groups for bumps up in the CIG heights by several hundred feet or more are currently in place at KMDT and KLNS from 14-16Z today as the low level wind direction veers a bit more to the SW and vertical mixing deepens with drier air being entrained into/eroding the cloud deck. Overall for today, a light sfc W/SW wind of 5-10 kts develops across Central PA. Any MVFR cigs over the Lower Susq Valley should lift/mix out by 16Z. A few SHRA or TSRA could develop later in the day, esp across northern PA as an upper level disturbance slides SE from the Great Lakes region, but most of the day should be dry. Outlook... Mon-Thu...Scattered SHRA/TSRA with brief restrictions possible; morning fog possible. &&
