Area Forecast Discussion
National Weather Service Pittsburgh PA
307 AM EST Wed Jan 18 2017

.SYNOPSIS...
Temperatures will remain well above normal into the weekend, with
rain showers from time to time.

&&

.NEAR TERM /THROUGH TONIGHT/...
Shortwave/closed low moves across the region this morning with
scattered showers. With weak cold advection, temperatures will
not recover much from morning lows, but will still remain well
above seasonal averages.

The mid level low is progged to shift southeast by late Wednesday
morning and building high pressure will help diminish
showers as the day progresses. Temperatures will have a small
rebound from morning readings, as weak cold advection continues.

Dry with relatively mild temperatures tonight as a mid level ridge
begins to build across the region.

&&

.SHORT TERM /THURSDAY THROUGH SATURDAY/...
Dry and mild weather will continue Thursday under mid level ridge,
before a closed low over the Central Plains opens and lifts
northeast for Friday. This will bring a round of rain and
continued mild temperatures. Heights will then rise again for
Saturday as this system exits, with a dry and mild start for the
weekend.

&&

.LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/...
Models differ on timing and placement of a strong upper low that
will develop over the Southern Plains and move northeast Sunday
into early next week. Using a general model blend for the system
brings period of rain Sunday into Tuesday with temperatures
between 10-15 degrees above normal.

&&

.AVIATION /08Z WEDNESDAY THROUGH SUNDAY/...
MVFR forecast at most ports, but FKL and DUJ look to hang around
in the IFR cat. Its very possible, especially around dawn, that
ports with MVFR cigs will see a brief period of IFR. Have covered
this risk with a tempo group. Forecast soundings are indicating
that winds could gust from 15 to 20kts at any time, so have
increased winds from previous forecast.

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

&&

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