.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
VFR conditions are favored at all TAF sites through the rest of
the night, though recent satellite imagery does show some patchy
valley fog beginning to form across northern PA. Mainly clear
skies and light winds should allow for the fog to continue to
expand, potentially getting close to BFD and IPT over the next
few hours. 

A weak shortwave moving overhead during the day will bring the
chance for a few showers to the region. The wave will have
relatively little moisture to work with for this time of year,
so showers are expected to remain isolated to scattered at best.
BFD has the best chance for seeing rain, so the PROB30 has been
maintained there. Some guidance suggests that some rain could
make it to JST and UNV as well, but confidence in coverage is
too low to mention the potential in the TAFs for now. Winds
during the day tomorrow will be out of the west at 5 to 10 knots
with a few gusts to 15 knots possible, especially at BFD and JST.

Chances for fog are slightly higher Wednesday night into
Thursday morning as surface dew points begin to climb ahead of a
more energetic shortwave trough that will move through for
Thursday. Increasing mid and high clouds ahead of this feature
may mitigate the fog threat somewhat, so we will hold off on
introducing any visibility restrictions for now. Showers and
possibly a thunderstorm or two associated with this disturbance
will begin moving in from the west after 06Z.

Outlook... 

Thu...Periods of showers and perhaps some t-storms focused 
across the southern half of central PA. 

Fri...AM fog, otherwise trending VFR.

Sat-Sun...Scattered to numerous showers/t-storms likely especially
on Sunday.
