Winter Storm in Maryland, March 2 to 4, 2019
An upper level shortwave moved through the Pittsburgh County Warning Area the evening of March 3rd/early morning of March 4th. Models from this event suggested that a coupled jet, saturation up through the dendritic growth zone, and frontogenesis across our area would support decent snowfall accumulations.

What happened
The episode as NWS PBZ wrote it up.
An upper level shortwave moved through the Pittsburgh County Warning Area the evening of March 3rd/early morning of March 4th. Models from this event suggested that a coupled jet, saturation up through the dendritic growth zone, and frontogenesis across our area would support decent snowfall accumulations. While the Pittsburgh region accumulated just above three inches, the higher elevations got near 6 inches.

.SYNOPSIS...
Dry but cold today. Widespread snowfall is expected with Sunday
low pressure.
&&
.NEAR TERM /THROUGH TONIGHT/...
Another shortwave trough will skirt north of our region today,
with scattered snow showers possible this afternoon across
northern counties and ridges where soundings indicate weak
instability. Otherwise, weak cold advection will keep temps just
below seasonal averages.
&&
.SHORT TERM /SUNDAY THROUGH MONDAY/...
A large scale winter storm is still progged to move across the
Deep South and into the Mid-Atlantic Sunday into Monday morning,
producing accumulating snow across our region. A Winter Storm
Watch remains in effect for higher elevations Sunday into Monday
morning where better confidence in higher totals exists.
Elsewhere, there remains uncertainity regarding the location of
the highest accumulating snow. However, model indications of
coupled jet support, saturation up through the dendritic growth
zone, and frontogenesis across our area provide support for
decent snowfall accumulations area-wide.
Snowfall end timing Sunday evening will be determined on
location and magnitude of deformation zone and how quickly it
will pass through the area. Generally, accumulating snow should
end before midnight across most with the exception of the ridge
zones where snowfall may linger into the early overnight period.
Dry weather is anticipated Monday under building high pressure.
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
The first half of the week will be characterized by well-below
average temperatures due to consistent upper-troughing.
Moderation is expected thereafter in southwest flow and warm
advection.
&&
.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
Stubborn MVFR/local IFR cigs are still expected to improve to
low-end VFR this afternoon with passage of a weak reinforcing
frontal boundary. That boundary will veer wind slightly to the
west and maintain speed nr 10 kts until evening.
Otherwise, condition deterioration is confidently forecast on
Sunday as a strong shortwave trough spreads snow over the
region.
.Outlook...
Cig restrictions are then possible through Wed with broad upper
troughing and cold advection.
