.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
The steadiest rain has exited Central PA early this afternoon 
as the best synoptic-scale forcing has moved over New England. 
A cold front will continue moving eastward across the 
Commonwealth this evening, with flight restrictions improving to
VFR regionwide later today (primarily between 23Z Wednesday to 
01Z Thursday). A narrow corridor of instability (MLCAPE up to 
around 100 J/kg) has been projected to develop ahead of this 
front over Eastern PA (KMDT/KLNS), though a downtrend in 
destabilization has been observed on latest CAM runs (e.g. HRRR 
& 3km NAM). As a result, brief visibility restrictions to around
5SM are possible underneath any heavier showers, with thunder
remaining unlikely.

Overnight, clearing skies and light winds will favor fog 
development & low-lying frost across the Northern Tier (KBFD). 
Even the pessimistic NAM keeps possible fog development largely
contained to the Northern Tier, with lower fog probabilities across
East-Central PA with surface winds closer to 5 kts. Otherwise, 
regionwide VFR is expected through the end of the TAF period.

Outlook...

Thu...Patchy morning fog across Northern Tier. Otherwise, VFR 
with some spotty afternoon/evening -SHRA.

Fri...VFR with some spotty afternoon/evening -SHRA.

Sat...Restrictions possible in -RA.

Sun...VFR favored early, with restrictions becoming more likely
in the afternoon as cold front moves SE. -SHRA with isolated 
-TSRA possible as cold front passes through.

Mon...VFR favored, with restrictions possible SE from lingering
-SHRA/-RA.
