The Canadian and German had the best looks for last night but its hard to beat the UK/Euro combination. Really hard.

The Euro's 500mb prediction could be spot on, but it be 2 or 3 too warm at the surface and it's showing a significant ice-storm.  Even verbatim, it's showing .1 to .2 falling by 10am Sunday morning with temps below freezing down in to the upstate.

 

Unlike the last non-event we had a few weeks ago with a similar set-up. It appears likely  this time we're going to get solid precip moving in quickly to take advantage of wet-bulbing. Temps on most of the modeling Sunday at 1am are around 32/10.  WAA isn't super strong and mid-level temps aren't torching either. 

If a meso/insitu high can develop from the precip over-running the cold dry air, and thus keep southerly surface flow at bay then it could be a solid freezing rain/sleet event.  Too early to determine how that will play out though.

Agreed. It's not out of the realm of possibility, I just find it doubtful.

Even Boone wouldnt be all snow on the Euro. The UKMET was even further away from anything significant.

My goodness, where is the cold air when you need it, and it doesn't have to be no where near as cold as a couple of weeks ago, just marginal.

NWS GSP discussion from early this morning:

Quote

.LONG TERM /SATURDAY THROUGH TUESDAY/...
As of 315 AM Wed: On Saturday, high pressure will once again
drift off the East Coast, and a shortwave trough will begin to
approach it from the west. However, this event looks to pan out a
little differently for our area than the one in the middle of the
week. The models have come into reasonably good agreement on its
evolution. The shortwave will induce cyclogenesis along the warm
front near the western Gulf Coast, and the developing system looks
to pass across or south of our CWFA on Sunday. The high will be in
position to support the possible development of an in-situ wedge
as precip spreads in from the west Sunday morning. Accordingly
model thermodynamic profiles and partial thickness trends suggest
a full range of p-types are possible Saturday night and Sunday
morning. Temps are still expected to warm enough for a change to all
rain for the afternoon, though guidance may not yet be taking the
full effect of the wedge into account. As the low begins to move up
the East Coast Sunday night, the wraparound moisture and CAA could
re-introduce snow over the mountains and NW NC Piedmont. Confidence
is still low on any snow or ice accumulations, though we are getting
into the part of the year in which freezing rain is climatologically
unusual. Nonetheless a large portion of the area could be impacted
Saturday night into Sunday with snow and sleet; current model QPF
suggests appreciable travel issues if p-types pan out as expected.

The canadian continues to be rock steady and tracking the low through northern GOM and off the SE coast. GFS is locked in on a well inland track through the interior of the SE. Probably how both models are handling the pac ridge and its net effect on the energy as it comes down, hence Can and Icon take a deeper dive which equals better results. For now because the Can has been more consistent along with the ICON to a degree I would lean in its direction before Id put my trust in the GFS. Ukmet and Euro will be interesting the next few cycles and probably come in somewhre between theCAN/Icon v/s GFS solutions.

The pattern is still gonna be northern stream driving/ almost independent through Feb. So gonna have to root for vorts to amp just right in this fast flow. Not gonna get alot of help from stj.

GFS vs CMC with surface temperatures Sunday morning at 7AM.  Plenty of precip on both, but temps are different.  GFS farther north with storm track

About 6 degrees different IMBY, could have bid ramifications, if CMC is right, and I think it's better with temps most of the time!

@griteater Good to see world's difference imo regarding GFS vs CMC, as well all know GFS does not handle 2m and cold all too well. Looking forward to the NAM getting in its range. I do worry how amped the GEFS is as franklin had pointed out. 

Edit: Although it does buck the trend this year of more sheared out and squashed pieces of energy, so I am not sure I firmly believe the GEFS at this point.

CMC isnt really that good though for anyone in NC or even VA for that matter.....

This looks good for NW NC and SW VA till you look at temps for the same frame

This wont get it done.....too warm at the surface everywhere pretty much

Seen some good wet snows at 34. Heck even 36. West of 77 and north of 40 looks good on this storm.

Keep in mind the wedge is underdone a lot of times. Probably why GSP is harping this early
