Area Forecast Discussion
National Weather Service Pittsburgh PA
730 AM EDT Fri Oct 20 2017

.SYNOPSIS...
High pressure will maintain dry and warm weather through the
weekend.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
High pressure at the surface and aloft will again spread
eastward across the Upper Ohio Valley today. Another day of dry
and warm weather, with plenty of sunshine.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY/...
High pressure will remain anchored through the weekend, keeping
it warm and dry. Despite an increase in cirrus and the ridge
axis shifting east late Saturday, increasing southwesterly flow
will allow temperatures to climb further and by Sunday readings
will be about 15 degrees above average.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
High pressure ridge shifts east Sunday night into Monday as the
broad western CONUS trough trudges eastward. Models differ
slightly in the evolution and timing of the trough, but despite
these timing differences, a pattern change will occur early
next week, bringing rain and eventually much cooler
temperatures.

&&

.AVIATION /12Z FRIDAY THROUGH TUESDAY/...
Outside of some early MVFR fog at ZZV and DUJ, VFR conditions
are once again expected through the period underneath high
pressure.  Winds will remain light out of the southwest.

.Outlook...
Restrictions are likely with a Monday cold front.

&&

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