On the parallel topic...have there been any trends with the 12Z parallel correlating to what the 00Z GFS OP will show? Just curious/interested on the timing and any connection?

ILN:

QUOTE
The large-scale weather features for Thursday and Friday continue to
be handled fairly well by the models, but specific details over the
Ohio Valley have seen some significant adjustments across the last
few GFS/ECMWF runs.
A period of warm advection will begin late
Thursday, before wave of low pressure is expected to move across the
southern Great Lakes, eventually ending up near or just south of the
region by Friday. Precipitation may not be significant with this
system, but the southerly push will likely result in cooler max
temps on Friday than previously forecast -- and this has been
adjusted.

Beyond this boundary setting up in the vicinity, the forecast
specifics through the weekend become very uncertain, with GEFS
members completely losing phase/amplitude continuity of the 500mb
pattern by Saturday night. Downstream and south of strengthening
upper flow, cyclogenesis is expected to occur somewhere upstream of
the region, with precipitation chances increasing Saturday. It
remains very unclear where any surface low may actually track, and
thus both the precipitation and temperature forecasts are notably
subject to change from this point of the forecast forward.

CLE

QUOTE
LONG TERM /THURSDAY THROUGH SUNDAY/...
Considerable uncertainty remains with the forecast late this week
and into the weekend. Quasi-zonal flow on Thursday will transition
to more of a fast northwest flow by Friday with a series of
clippers sliding through the region. Models have made some
sizable changes over the last 24 hours, likely in response to
better sampling of the trough along the west coast.
The first
clipper is progged to pass near or north of the forecast area on
Thursday night, followed by another passing to the south on
Saturday night. Trended temperatures down Friday into Saturday
as models have trended towards more of a trough aloft. Forecast
will continue with chance pops through much of the extended as
confidence is low on timing and precip type associated with
these features.

Yeah, but after this winter, I'm not sure any of us have any positive expectations for wintry weather...If we catch lightning in a bottle, great!...if not, oh well, we're used to it & spring is right around the corner.
