Area Forecast Discussion...UPDATED
National Weather Service Pittsburgh PA
113 AM EDT Fri Oct 20 2017

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

&&

.NEAR TERM /THROUGH TODAY/...
Overnight period is in good shape, no changes needed.

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 /TONIGHT 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 /05Z FRIDAY THROUGH TUESDAY/...
VFR is again expected through the forecast period. Building
high pressure will also ensure light surface winds.

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

&&

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