Area Forecast Discussion
National Weather Service Pittsburgh PA
641 PM EST Tue Jan 17 2017

.SYNOPSIS...
While a cold front crossing the region will bring
temperatures closer to normal on Wednesday, the entire 7 day
forecast period will have above normal temperatures. The next
time for widespread rain will be Friday.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
The cold front is currently in progress moving across the
region with a line of heavier showers shifting from west to east
across the northern half of the forecast area. Rain will also
continue across areas near Morgantown during the afternoon.
Although conditions will temporarily dry out during the evening,
an upper low will race across Ohio and Pennsylvania around
sunrise. Have stuck with chance pops for that time period so far.
Cannot rule out a lingering shower into Wednesday afternoon, but
the bulk of any rain that develops will have moved east by then.
Tonight`s low temperatures will actually remain slightly above
normal high temperatures for mid January, with only a minimal
rise in values on Wednesday.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY NIGHT/...
High pressure will move into the region from the southwest and
allow for dry weather Wednesday night and Thursday before another
low pressure system brings precipitation late Thursday night
through Friday evening. While precipitation may start as snow
from Pittsburgh north, current forecast keeps any accumulation
less than an inch. Temperatures will be about 10 degrees above
normal.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
An upper low will develop over the Southern Plains Saturday
and slowly move up the East Coast through the extended forecast
period. This system should bring rain to the region by Sunday and
keep rain in the forecast through the rest of the forecast. Warm
weather will continue, with temperatures between 10-15 degrees
above normal.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
A brief period of VFR conditions is expected during the evening
hours. Conditions will deteriorate to MVFR and then IFR overnight
as an upper low approaches from the west, along with another
period of scattered showers. Some improvement to MVFR is possible
past sunrise, but restrictions will continue overall. West to
southwest winds of around 10 knots are expected.

.OUTLOOK...
Expect general VFR from late Wednesday until the next system
moves in on Friday.

&&

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