Area Forecast Discussion
National Weather Service Pittsburgh PA
903 PM EST Sun Nov 19 2017

.SYNOPSIS...
Remaining snow showers will diminish as the night progresses.
Dry and seasonal conditions are expected until the approach of
another cold front late on Tuesday.

&&

.NEAR TERM /THROUGH MONDAY/...
The late eve update included adjustments to hourly trends as
snow showers are on the wane for most areas as sfc wind is
backing to the west.

The embedded shortwave in NW flow aloft will depart late
tonight with inversion levels falling and suppressing remaining
activity upslope off the Lakes and over the I 80 corridor.

Building high pressure will ensure a dry Monday with some
moderation in temperature due to insolation and warm advection.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
High pressure will remain in control through Tuesday, with highs
getting closer to seasonal norms ahead of an approaching cold
front, progged for passage Tuesday night. The models have been
hinting to a slightly more amplified shortwave passage, but this
would still keep moist of the lift focused over the northern
half of the region. Kept PoPs rather consistent for now, with
adjustments needed as guidance comes more in line with a
solution.

Temperatures will cool back down - and run about 10 degrees
below average Wednesday.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
Broad troughing pattern will remain in place through the weekend
with fast moving systems progged Friday and Saturday. Similar
to Wednesday, most of the lift remains situated north so other
than some continued colder than average temperatures, PoPs were
kept rather low.

&&

.AVIATION /02Z MONDAY THROUGH FRIDAY/...
Scattered snow showers will gradually diminish tonight, although
MVFR, to low-end VFR stratocu will persist into the predawn of Monday.
Improvement is forecast thereafter with building high pressure.

.Outlook...
Restriction potential returns with a Tue cold front and subsequent
upper troughing through mid week.

&&

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