.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
VFR conditions continue through the mid morning hours today across
the Western Mtns of PA, until the early afternoon hours
throughout the Central Mountains and likely through the mid 
afternoon hours over the Lower Susq Valley. 

In the meantime, Central and Western PA airfields will feel the
impact of a southerly Low-Level Jet leading to Low-Level Wind
Shear. The longest periods of LLWS will be at KBFD, KJST, KAOO
and KUNV - through 18-20Z today. Peak southerly winds around the
2000 FT AGL level will be between 45-50 kt at KBFD during the
mid to late morning, and in the low 40 KT range from KJST to
KAOO and KUNV with values between 35-40 kts over the Susq
Valley.

Cigs drop to IFR by 20-21Z over the airfields of KJST and KBFD
and around dusk (01Z Wed) at KUNV. The airfields of KAOO, KIPT,
KMDT and KLNS should only drop to MVFR - CIG-wise. 

The probability for showers today will vary from 60-75 percent 
over the Central and Western Mtns to 40-55 percent over the
Lower and Mid Susq Valley respectively. 

For tonight/early Wednesday, conditions will deteriorate to IFR
with areas of LIFR Cigs and fog across the Western Mtns of PA 
after midnight.

Outlook...

Wed...MVFR/IFR favored due to low cloud ceilings & rain 
overspreading the region.

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

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