The episode as NWS PBZ wrote it up.
Low pressure tracked from the Plains to the upper Midwest on February 20th, before transitioning to a coastal system by the morning of the 21st. This low pushed a warm front northward across our region. Widespread precipitation was generated by deep moisture and an area of strong lift that accompanied the warm front. Precipitation started mainly as snow, but transitioned to a mostly brief period of mixed precipitation as warmer air moved in aloft. By late evening on the 20th, the passage of the warm front allowed all precipitation to change to rain.

Area Forecast Discussion
National Weather Service Pittsburgh PA
1240 AM EST Wed Feb 20 2019
.SYNOPSIS...
Snow will move in from south to north after midnight, with
mixed precipitation expected across the region on Wednesday
before transitioning to rain Wednesday night.
&&
.NEAR TERM /THROUGH TODAY/...
Adjusted sky cover for the latest update, with clouds
overspreading the area.
Previous Discussion...
Snow will move in from south to north after midnight, with 1-3
inches possible between midnight and sunrise south of Interstate
70.
The mixed bag of precipitation will start Wednesday morning,
with warmer air moving in aloft before warmer air moves in at
the surface. This will result in a transition zone of icy
precipitation for a couple of hours, with primarily freezing
rain but sleet also a possibility. By noon a small area of snow
should remain across the northeast, there will be a wide area of
multiple precipitation types, and all rain from Wheeling to the
south and west. As the afternoon continues, most locations
should transition to all rain, although freezing rain will
likely hang on a bit longer across northeastern counties and
across eastern Garrett county.
No changes were made to any of the headlines that were
previously issued. This includes an Areal Flood Watch primarily
from Interstate 70 south; a Winter Storm Warning for Garrett,
eastern Tucker, Fayette Ridges, and Westmoreland Ridges; and a
Winter Weather Advisory for the rest of the forecast area.
All locations will end up with at least a glaze of freezing
rain, while the warning counties could receive over a quarter
inch of freezing rain.
&&
.SHORT TERM /TONIGHT THROUGH FRIDAY/...
Freezing rain could still persist a little bit across northeast
counties and eastern Garrett county Wednesday evening, but
generally all precipitation should be falling as rain, possibly
transitioning to snow as it comes to an end Thursday morning.
Thursday afternoon, Thursday night, and Friday should all be dry
as high pressure moves into the region. Temperatures will be
seasonable during the daytime with highs in the 40s, with 30s
expected Wednesday night and 20s for Thursday night.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
A large storm system will develop across the eastern United
States Saturday into Sunday, with precipitation starting to move
in Friday night and Saturday, with widespread rain continuing
Saturday night and temperatures starting to drop as a cold front
moves through Sunday. As the low pressure center moves east
Sunday night into Monday, showers may change over to snow. The
next system could bring some light rain or snow showers on
Tuesday. The warmest time period will be Saturday night and
Sunday, with temperatures rising into the 50s before falling
back towards freezing Sunday night.
&&
.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
Precipitation onset, in the form of snow, is expected to occur
between 08Z and 12Z from south to north, with a fairly rapid
deterioration to IFR/MVFR conditions. IFR conditions will then
persist as a mix with freezing rain and sleet occurs, and then
followed by a change to rain at most sites by/during the
afternoon. DUJ has the potential to hang on to this wintry mix
the longest, potentially beyond 00Z Thursday. As a low level jet
develops ahead of an advancing warm front during the afternoon,
low level wind shear will also become a possibility.
.Outlook...
Widespread restrictions will continue through Wednesday night
with the crossing warm front. Restrictions and gusty wind are
expected Thursday with the passage of a cold front. Restriction
potential returns with weekend low pressure.
