.AVIATION /12Z TUESDAY THROUGH SATURDAY/...

Overnight fog and low stratus will have mixed out regionwide by
13-15Z today, when S-SW flow will pick up to around 10-15 kts 
ahead of a progressive low pressure system sliding across the 
Great Lakes. A few showers may move across the Northern Tier 
(KBFD) during the morning and afternoon as the system passes to 
our north. There is too low confidence on afternoon showers to 
include in TAFs. Otherwise, little to no precipitation is 
expected across our area, as supported by upper-level 
suppression under the right-exit region of a jet streak. This 
jet streak will likely introduce LLWS concerns across the 
airspace between 00Z and 12Z Wednesday up to 40 knots and then a
continued risk of 30-35 knots after 12Z for the morning. This 
low level shear will persist through the overnight hours 
tomorrow until the exit region of the jet has lifted northeast.
Mostly VFR conditions expected through the day, but may see 
some drops down to MVFR or IFR for the northern sites (KBFD and 
KIPT) as lower ceilings move over the area early Wednesday 
morning.

Outlook...

Wed...Restrictions from low ceilings and -SHRA possible as the
front moves southward across the Commonwealth.

Thu...A period of VFR is favored behind the front, with a chance
for restrictions and -RA later on Thursday as the front 
oscillates back northward.

Fri...Scattered -SHRA and isolated -TSRA could bring 
restrictions across the region with cold FROPA. W-NW winds may
gust up to around 25-35 kts behind the front.

Sat...Localized restrictions possible early due to post-frontal
stratocumulus and lake-effect -SHRA/-SHSN, primarily across the
Northern Tier. Otherwise, VFR prevailing with NW-NNW wind gusts
up to around 25-35 kts possible regionwide.
