Area Forecast Discussion
National Weather Service Pittsburgh PA
1240 AM EDT Wed May 23 2018

.SYNOPSIS...
High pressure will build in the wake of this evenings cold front
and provide a few days of dry weather and seasonable temperature.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
Precipitation associated with a prefrontal trough are exiting to
the south currently, after producing some flooding in a few
spots. Remaining showers along the dewpoint gradient just north
of Pittsburgh should remain isolated as that boundary drops
across, such that only isolated showers should remain in the
southeast counties by dawn. Temperatures/dewpoints are in good
shape and made only minor tweaks.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH FRIDAY/...
A pattern shift is in the works for the latter part of the week,
bringing drier weather areawide. In the wake of tonight`s cold
front, showers will have all but dwindled by Wednesday morning.
Dry high pressure will maintain dry weather through Friday.
Temperatures will steadily climb back up to well above average
by Thursday and Friday, with higher humidity levels returning by
the weekend.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
As quickly as the dry weather arrives this week, it appears it
will come to an end heading into the holiday weekend. Moisture
gets pumped northward around a potential Gulf tropical system,
and shortwave trough moving over the flattened ridge will
provide support for several rounds of precipitation.

Temperature are expected to be moderated by the clouds and rain,
but will remain at least a few degrees above average.

&&

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
MVFR/local IFR is expected behind a crossing cold front. The
stratus/stratocu cigs should lift with mixing and heating this
morning, and eventually scatter out with VFR for the rest of the
TAF period under building high pressure.

OUTLOOK...
Restriction potential returns with weekend low pressure.

&&

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