Area Forecast Discussion
National Weather Service Pittsburgh PA
416 AM EDT WED JUL 27 2016

.SYNOPSIS...
Warm and dry weather can be expected until the approach of low
pressure on Thursday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Whatever is left of the weak boundary over West Virginia will
continue to wobble under the zonal flow aloft. Each small
juxtaposition is caused by the passage of upper level energy in
the aforementioned flow. With daytime heating, and its resultant
atmospheric destabilization, spotty convection could fire over the
southern edge of my forecast area. The good news for most of us is
the real juicy air will remain shunted to the south, and allow for
warm but comfortable conditions.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/...
POPs will be on the increase with the approach of low pressure on
Thursday. For now, highest POPS and QPF resides over the
southeast portions of the forecast area where the track of the low
should progress. Still seeing model differences in the path of
surface wave and the upper level support which will enhance it
Thursday afternoon and Thursday night.

System will slowly exit Friday decreasing pop and cloud coverage.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
A series of shortwaves and development of a broad, but shallow
trough over the Eastern CONUS is forecast to support periodic rain
chances and seasonal temperatures through the weekend. Ridging
should return dry weather by the middle of next week.

&&

.AVIATION /08Z WEDNESDAY THROUGH SUNDAY/...
MVFR visibility restrictions possible early this morning at
DUJ/FKL despite dewpoints in the 50s where limited cloud coverage
will allow for temperatures to approach dewpoints before sunrise.
VFR conditions are expected south of I-80 where mid-level cloud
coverage should lessen radiational cooling. MVFR/IFR conditions
are possible south of the PA border closer to a stationary
boundary where lower levels are near saturation.

.OUTLOOK /WEDNESDAY NIGHT THROUGH SUNDAY/...
Low pressure should return potential restrictions late Thursday
and Friday, with upper troughing maintaining periodic restriction
chances through the weekend.

&&

.PBZ WATCHES/WARNINGS/ADVISORIES...
MD...None.
OH...None.
PA...None.
WV...None.
