.AVIATION /08Z WEDNESDAY THROUGH SUNDAY/...
An area of low pressure will move northeast over the Ohio River
Valley and cross Central PA late this afternoon through early
tonight. 

Gradually lowering Cigs and Vsbys will precede and accompany a
broad area of rain near and to the north of the low's track. 

Look for LIFR conditions at KBFD through the mid-late morning 
hours at KBFD likely improving slightly to plain IFR CIGS and
VSBYS for the afternoon and early evening today. In the moist 
upslope flow in the wake of the rainfall tonight, cigs will 
likely drop several hundred feet - back into the LIFR range 
while vsbys fall into the IFR category. 

KJST has seen the best CIGS and overall conditions (VFR) so far
as they're residing in a narrow warm sector with a light SSW 
breeze. 

Elsewhere, slightly cooler air and a light east-southeast wind
was leading to widespread MVFR Cigs, but mainly VFR vsbys.

Removed low vsbys as the cloud cover should help to maintain a
few to several deg F temp/dewpoints spread with MVFR vsbys
through at least this morning, prior to the onset of the
steadier rain arriving from the SW later this morning and early
this afternoon. The brunt of the steadier rain will fall in a 6
to 8 hour window at most airfields. 

After the aforementioned sfc low heads to the NJ/Southern New
England coast tonight, the leftover llvl moisture and light 
NW/upslope breeze will cause lowering Cigs and Vsbys into the
LIFR range across the Western Mtns of PA and MVFR to IFR
elsewhere. 

Outlook...

Wed...MVFR/IFR favored due to low cloud ceilings & rain 
overspreading the region. A few -TSRA are possible across 
Southern PA this afternoon, but they weren't included in any 
TAFS as a result of the fairly low probability and generally 
weak instability to support their development.

Thu...VFR/MVFR in the morning as rain ends west to east, 
becoming VFR in the afternoon.

Fri-Sat...Mainly VFR with brief restrictions possible in 
showers.

Sun...Restrictions possible northwest in -RA and possibly some
-SN.
