Area Forecast Discussion
National Weather Service Pittsburgh PA
333 AM EDT Mon Aug 22 2016

.SYNOPSIS...
High pressure will provide cooler and drier conditions through
the first half of the week.

&&

.NEAR TERM /THROUGH TONIGHT/...
As a mid-level trough exits the region to the east, some lingering
clouds have remained across the forecast area, but the clouds
should depart by the afternoon. With high pressure dominating the
central United States, northwesterly flow is expected across the
region. Not only will this bring cooler temperatures, it will
bring drier air. Instead of dewpoints in the 60s and 70s,
dewpoints will only be in the 50s. Clear skies and light winds
will allow for the coolest night in at least two weeks, with all
locations dropping into the 50s and isolated areas dipping into
the 40s.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
As high pressure eases east, winds will shift from the northwest
to the southwest, bringing a return to warmer air across the
region. Highs will rise back into the mid 80s by Wednesday. The
weather will be dry through at least Wednesday, before the first
isolated showers in advance of a cold front bring a chance for
rain to western counties late Wednesday night.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
The main weather maker this period is a cold front currently
expected to cross on Friday. Humidity will continue to increase
ahead of it, with shower and thunderstorm chances returning for
Thursday and Thursday night. The situation may be similar to the
front which just crossed our region, since the main shortwave will
likely remain off to the north like this past system. Dry weather
returns Friday night and continues through the weekend with the
return of high pressure. Temperatures will remain near or just
above seasonal levels through the period.

&&

.AVIATION /07Z MONDAY THROUGH FRIDAY/...
VFR is expected tonight for most ports, though a crossing upper
trough should bring stratocu ceilings overnight from PIT north.
Areas north of I 80 have the best chance at seeing MVFR ceilings
in NW flow. CU rule indicates a diurnal CU layer for Monday with
possible MVFR ceiling heights in the morning, though mixing and
building high pressure should return VFR conditions to the area by
afternoon.

.OUTLOOK /TUESDAY THROUGH FRIDAY/...
Restriction potential returns with the approach and passage of a
cold front Thursday and Friday.
