Area Forecast Discussion
National Weather Service Pittsburgh PA
530 PM EDT Wed Oct 18 2017

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

&&

.NEAR TERM /THROUGH THURSDAY/...
No major changes were needed as high pressure continues to
suppress rain chances. Insolation and weak warm advection will
drive Thursday highs nearly 10 degrees above averages.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
The building high pressure dome will continue to moderate
temperature through the weekend. Expect afternoon highs
approximately 15 degrees above average as the dry spell
continues.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
High pressure will push east allowing a cold front to reach the area
late Sunday night into Monday, with a second cold front pushing east
by Tuesday.  Models also indicate an upper level trough should build
across the region late in the period.

Expect precipitation chances will increase from the west Sunday
night with unsettled weather through the remainder of the period.

Temperatures aloft will become quite cool/cold with the trough
building in.  However, surface temperatures should act to keep the
precipitation in the form of a cold rain.

&&

.AVIATION /22Z WEDNESDAY THROUGH MONDAY/...
High pressure will maintain VFR and light wind into Thursday. By
afternoon, a somewhat tighter pressure gradient will support
gusts around 15 kts.

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

&&

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