LWX is using the cutoff low verbiage, though it might not be the prototypical, meandering cutoff low that we see over the sw states...
.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
The long term begins with a strong upper level trough digging across
the Mississippi Valley on Saturday. Recent model runs have the
trough digging deeper and moving slower bringing impacts later in
the weekend. Saturday will be mild with high temperatures in the 40s
for most (30s at higher elevations) and clouds clearing in the
afternoon, and breezy conditions throughout the day. As the trough
approaches from the west, a cutoff low develops over the southeast
and begins moving up the east coast. There is still a good bit of
model uncertainty regarding the timing and placement of the cutoff
low.
Model guidance is trending slower with precipitation reaching the
forecast area early Sunday and persisting throughout the day. As far
a wintry precipitation, model guidance is showing temperatures
staying above freezing east of the Blue Ridge. Those along and west
of the Blue Ridge have the highest chances of seeing snow, but cold
air aloft could infiltrate heavy precipitation bringing some snow to
the rest of the area. With this event being five days away, it`s too
early to tell in the way of wintry precipitation. We will continue
to monitor this system as it gets closer.
Current guidance shows the cutoff low exiting the area into the
Atlantic by Monday afternoon, but it`s too early to say with the
slower trend in guidance. Upper level ridging will build over the
area in the wake of the area of low pressure brining warmer and more
mild conditions.
