What forecasters said that day

The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Pittsburgh, PA wrote its last area forecast discussion before this winter storm warning went out at Feb 17, 1:00 AM EST, 57 minutes earlier.

Area forecast discussion, Feb 17, 1:00 AM EST, 57 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Pittsburgh PA
100 AM EST Sat Feb 17 2018

.SYNOPSIS...
A quick moving system brings snow to most locations Saturday
afternoon and evening. Next week should be warm and wet.

&&

.NEAR TERM /THROUGH TODAY/...
No changes to the overnight period.

Moisture starts to increase from the southwest today. This
will allow for mid and high clouds to increase from the
southwest this morning. This will allow for temperatures to
remain in check going into the latter half of the day as deeper
moisture again increases.

A short wave trough looks to shift through the lower Great
Lakes by the end of the day with the right entrance region of
the upper jet set to track straight through the area. A
bifurcated frontogenetical maxima field suggest one weakening
areas of 850-700 mb frontogenesis translates northeastward
across the eastern CWA through the late afternoon and early
evening hours while a second and much stronger one follows the
redeveloping surface low across the Appalachians. This results
in a heavier swath of QPF across the far southeastern portion of
the CWA. It is in this area that the forecast gets the
trickiest and thermal profiles come into play quite strongly.

NAM and GFS thermal profiles aren't a lot different going into
the afternoon and evening hours. They would suggest that enough
warm air creeps into the boundary layer west of the terrain to
at least mix with rain in places like Morgantown, Uniontown, and
Parsons. However, farther west and in the terrain itself,
precipitation would be mostly snow. That said, the ground isn't
that cold anymore after all of the rain, and temperatures will
be marginal. Snow ratios have been adjusted accordingly, and
accumulation potential, especially during the daytime hours, has
been held back significantly other than in the highest terrain.
Even with that in mind, snow amounts from this afternoon into
the evening will likely yield at least widespread advisory
accumulation in the terrain, with possible warming criteria on
the highest peaks.

&&

.SHORT TERM /TONIGHT THROUGH MONDAY/...
Deeper moisture departs to the east tonight. This yields a
questionable moisture profile as the dendritic layer dries out,
upslope flow remains, and precipitation is still probable to be
falling. This may yield a period of freezing drizzle, however
given the proximity of the lifting profile to the bottom of the
dendritic layer, it would seem poorly formed flakes are more
likely in the terrain than freezing drizzle at the moment.

Dry weather Sunday and most of Sunday night, with the bulk of
precipitation waiting until Monday to move into the area from
the west. Temperatures will be on the rise through the period,
with highs in the 40s on Sunday and 50s/60s on Monday.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
Upper level pattern should allow for the chance of precipitation
to continue through much of the week. The warmest temperatures
should occur on Tuesday before a cold front moves through on
Wednesday, with locations from Pittsburgh south likely to reach
70 degrees ahead of the front.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
The broken to overcast stratocu layer will take most of the
night to dissipate as subsidence helps to erode the clouds from
the northeast. Ongoing restrictions will ease by dawn, with
light winds expected.

Clouds will increase this afternoon as moisture surges nwd
ahead of an approaching disturbance. Snow will impact many
terminals by afternoon with some rain possible around MGW.

OUTLOOK...MVFR conditions will continue Saturday night and again
Monday into Tuesday.
