.AVIATION /15Z WEDNESDAY THROUGH SUNDAY/...
Surge of low level moisture from south to north will likely 
bring MVFR ceilings into parts of the southern PA airspace 
into at least early this afternoon, esp in the KJST area and
across the Lower Susq Valley (KMDT to KLNS area) where low 
level convergence zones associated with weak troughs (and a 
warm front across SE PA) will combine with the highest
Precipitable Water values to focus lower convective cloud 
bases. 

Cigs most likely trend back to higher end MVFR to low-end VFR 
for the mid to late afternoon. Best odds for a brief heavy 
downpour and localized MVFR/IFR visibility appears to be in the 
KMDT/KLNS vicinity this afternoon. Confidence is generally low 
regarding precip trends. Humid and stagnant airmass tonight 
suggests favors lowering flight cats toward MVFR into early 
Thursday morning. 

Outlook... 

Thu-Sun...Pockets of fog in the morning. Scattered showers/isolated
t-storms with heavy downpours and localized restrictions.
