.AVIATION /14Z MONDAY THROUGH FRIDAY/...
N/NE'erly surface winds will guide drier/continental air 
southward across much of the Commonwealth through Monday 
morning, with dewpoints trending down into the 50s areawide. 
Although conditions will trend drier near the surface, lingering
moisture aloft will blanket much of the area in mid/high clouds
(VFR), with sub-VFR ceilings favored throughout the day along 
the Allegheny Ridge terrain (mainly MVFR for KJST/KAOO, and 
perhaps IFR at KJST). Moreover, periodic MVFR is possible 
through Monday morning at KMDT/KLNS downwind of the Atlantic 
Ocean.

Another round of rain will gradually overspread the southern 
2/3rds of the Commonwealth throughout the day on Monday as a low
pressure drifts across the Mid-Atlantic, with a stout 1030-1040
mb high pressure over southern Canada looking to keep the 
Northern Tier (KBFD) mainly dry. Surface winds will trend 
E/NE'erly at the surface Monday night and bring marine air back 
into much of our area, with mid-level (850 mb) SE'erly flow also
helping to slowly bring moisture back north. This looks to 
favor a trend towards MVFR-IFR across all terminals Monday night
as moisture rebounds.


Outlook...

Tue-Thu...Restrictions possible from -SHRA/BR and low ceilings,
mainly S.

Fri...VFR favored as a developing coastal low looks to bring subsidence
overhead, though -RA and lower cloud ceilings associated with this
system may reach our eastern terminals.
