Area Forecast Discussion
National Weather Service Pittsburgh PA
129 PM 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. A lack of airmass change and clearing this afternoon
will ensure our temperatures remain 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-level ridge will build further, while slowly shifting
eastward over the region. This will keep the forecast dry and temperatures
well-above average through the early part of next week. Highs
will regularly push near the 90 degree mark across the lower
terrain.

&&

.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 /18Z FRIDAY THROUGH WEDNESDAY/...
-- Changed Discussion --
VFR conditions are expected under high pressure, with the
exception of valley fog in the hours around sunrise. Overall, think
that fog is likely to be more widespread/thicker south of PIT
where higher dewpoints may reside. Any fog will burn off by
14Z, with a resumption of VFR conditions.

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