Area Forecast Discussion
National Weather Service Pittsburgh PA
924 AM EDT Fri Sep 22 2017

.SYNOPSIS...
High pressure will maintain warm and dry weather through the
middle of next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Very little to discuss as we welcome Autumn`s arrival this
afternoon. High cirrus, best seen on the GOES-16 cirrus band,
will continue to stream in from post tropical cyclone Jose.
These clouds will be quickly shunted to our south by this
afternoon as drier air works in from the north. While the clouds
will initial hamper surface temperatures, lack of airmass
change and clearing this afternoon will ensure our temperatures
stay summer-like.

Clearing again tonight will promote the production of valley fog
in what is essentially a persistence forecast. Lows will stay
above average.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY/...
Upper ridge will continue to build across the eastern half of
the country between a large trough in the western United States
and a decaying Tropical Storm Jose. Temperatures should continue
to average 10 to 15 degrees above seasonal levels.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
Dry weather continues through most of the long term. At this
point, ensembles not really hinting at much rainfall until late
in the period with the passage of a cold front. Temperatures
will stay above average until the front passes.

&&

.AVIATION /13Z FRIDAY THROUGH TUESDAY/...
High pressure will maintain VFR and light wind with exception
for peri-dawn fog. Fog may be less dense and less widespread
early this morning, as high cirrus clouds are expected to
increase.

.Outlook...
No widespread restrictions are expected with high pressure over
the region.

&&

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