Area Forecast Discussion
National Weather Service Pittsburgh PA
636 PM EDT THU JUN 16 2016

.SYNOPSIS...
Crossing low pressure will bring showers and thunderstorms to the
Upper Ohio Valley Region today.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
...Heavy Rain Threat Continues This Evening...

The severe thunderstorm watch has been cancelled as the main line
of convection and best shear depart to the southeast. As this
occurs, we will quickly be transitioning into a flash flood
threat environment over the next few hours. Available instability,
while unimpressive, remains sufficient to generate some convection
activity, especially with nearly moist adiabatic profiles and some
unremarkable positive area. Also, given mesoanalysis trends
suggesting the instability ridge continues to ride into western
Pennsylvania while model shear profiles weaken drastically as the
upper low transitions southeastward, it would seem the movement of
additional storm cells will become progressively slower through
the evening. Combining this with the preferred corridor for ascent
likely falling in a NW-SE oriented deformation zone that will be
dropping across the urban area this evening with skinny CAPE
remaining through the night with a near-zero shear environment
throughout the evening and into the overnight, the threat is very
real for heavy rainfall in successive rounds. When you combine
this with the fact that flash flood guidance values are only
around 0.60 inches in an hour over portions of the metro
Pittsburgh area, flash flooding is a very real threat going
forward over much of western Pennsylvania. Thus, a flash flood
watch remains in effect for most of the area from generally the
northern panhandle of WV eastward. Fries

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY/...
Building high pressure will improve conditions rapidly behind the
exiting low. Expect Friday and Saturday temperatures near the
average with more comfortable humidity levels as per lower dewpoints.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
That high is progged to maintain dry and seasonal weather into
early next week. Northeast flow in the boundary layer may
initially limit temperatures to near, or a few degrees above the
averages, but rising heights aloft are signaling a rapid
moderation with temperatures for the period expected about 5 to
10 degrees above the near 80 average.

As mid week approaches, the models indicate frontal encroachment,
with passage currently slated for Tuesday. Rain chances have been
increased, and the temperature prognosis eased for that
eventually.

&&

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
Rounds of thunderstorms are expected over the next 9-12 hours as
low pressure approaches and crosses in an unstable atmosphere.
Tried to give 2 hour TEMPO windows in TAFs to time best threat,
but expect IFR or even LIFR impacts from storms are possible at
any time into this evening. Strong wind gusts are likely and will
attempt to amend with details as the threat develops. Activity
will begin to die down after 06Z, although low clouds and fog of
at least MVFR intensity are expected overnight until past sunrise
on Friday. VFR conditions are expected to be reestablished by
midday.

.OUTLOOK /FRIDAY THROUGH MONDAY/...
VFR conditions are expected through the weekend.
