What's an "active cold front"?

This morning's BOSC FA says:

SYNOPSIS...ACTIVE PTN CDFNT OVR ERN CSTL WTRS VA/MD/DE WILL MOVE
OVR INTL WTRS 12-15Z. OTRW..STNR BNDRY ACRS SWRN OH VLY THRU PD.
HI PRES WILL DMNT NERN PTN. BTR.

What does "active" mean in this context? Is there such a thing as an
"inactive" cold front, or is that just another way of saying stationary
front? Is there any difference between a "stationary boundary" and a
"stationary front"?

An active cold front would be one with frontal 'activity' associated with
it. Most likely there were some thunderstorms present.

Hi Roy

Ryan described an active cold front. An inactive cold front could
refer to a cold front that moves through dry air and causes no weather
at all. A stationary boundary and a stationary front are pretty much
the same.
