.AVIATION /15Z SUNDAY THROUGH THURSDAY/...
Flight categories and LLWS will improve from west to east across
the Central Ridge and Valley region of PA through this afternoon
in the wake of a cold front. 

MVFR ceilings are moderately likely (50-60%) to persist into the
mid afternoon 19-20Z at KUNV and KAOO as colder drier air works
in, while mainly VFR CIGS are expected to persist at the tail
end of an area of rain and afterward across the Susq Valley. 

Conversely, deepening cold air and the approach of an upper
level trough will combine with orographic lift to increase the 
chc for SHRASN this afternoon and evening at KBFD and KJST with 
IFR to MVFR CIGS. 

MVFR to briefly IFR CIGS will occur tonight into Monday at KBFD
and KJST with ocnl -shsn. Variable MVFR to low end VFR bkn cigs
will continue tonight acrs the Central Mtns with VFR at the 
Susq Valley Airfields. 

Wind gusts from 270-290 deg later today and tonight could exceed
30 KTs at times, as the colder air pushes in beneath the
subsiding (left rear) portion of an upper level jet max.  

Outlook...

Mon...Breezy and cooler with MVFR N/W and VFR elsewhere, with 
scattered rain/snow showers possible.

Tue...Mainly VFR with a few rain/show showers.

Wed-Thu...VFR.
