.AVIATION /09Z SUNDAY THROUGH THURSDAY/...
Typical westerly postfrontal upslope flow pattern stays locked 
in through Sunday morning with IFR to LIFR conds at KBFD/KJST 
and MVFR conds at KUNV/KAOO/KIPT. Periods of drizzle are likely 
in the central and western mountains through daybreak. Frequent
wind gusts 20-25kt from 260-300 degrees are expected through 
Sunday. Improvements to VFR are expected by late Sunday morning
as low-level moisture clears out, giving way to sunshine with 
some high clouds for the afternoon.

Another upper-level low will swing across the Northeastern US 
Sunday night through Monday and bring a return of lower clouds 
and -SHRA across our area. Flight restrictions will be most 
likely at KBFD (MVFR to IFR) and KJST (mainly MVFR), with 
intermittent MVFR possible across the Ridge and Valley region 
(KAOO/KUNV/KIPT) and VFR favored across the Lower Susquehanna 
Valley (KMDT/KLNS). Over NW PA (KBFD), cold air aloft may even 
support graupel in a few showers during this timeframe. 
Additionally, wind shear may approach LLWS thresholds across 
south-central PA (primarily KJST/KAOO/KUNV) Sunday night as 
westerly winds in the lowest 1000-1500 ft approach 35-40 kts.

Outlook...

Tue-Wed...Mainly VFR with SW to W winds gusting up to around 
15-25 kts during the daytime.

Thu...Leaning sub-VFR with rain and snow possible into late next
week.
