I suspect we'll see ISW's going up over the next few hours. I guess RAH could make an argument for staying at an advisory, but that seems a bit of a stretch. Every model I've seen on the 12z or later runs are showing warning criteria zr in the triad. For fun, check out the new Euro at 144........ let the trend begin.

Just dropped to 30.9 here in Colfax. NAM has us bottoming out at 29 tomorrow morning. Will be interesting to see what NWS does about advisories/warnings for later tonight and tomorrow morning.

Why are we not getting the true CAD wedge? For instance, the maps above show Durham more at risk than Mt Airy. Seems if a true CAD, Hickory to Mt Airy should be the heart of the freezing rain.

I remember a devastating ice storm up in Wytheville back in the mid 90's or so. Every yard I drove past had some sort of tree damage. Probably at least an inch of ice or so.
TW
Just keep in mind, we've seen alot of doomsday ice forecasts over the years that really just don't pan out - maybe due to sleet, maybe it's a bit warmer, maybe the precip is a bit lighter. Hopefully that's the case here.

Very interesting that the NAM shows the wedge retreating around daybreak on Saturday, but then digging back in as the morning wears on. I"m not sure I've ever seen that. Maybe the low is transferring to the coast and negating the surge of warm air?
TW
Burrel,
I think you're pretty spot on there. I liked the Euro except that I think it is missing the redevelopment off the SC coast. I think that redevelopment will reduce the surge of warm air and help lock the cad in a bit more.
TW
The low is about 6mb weaker and a bit further south (or maybe just slower?) and the hp is just a bit stronger, maybe 1mb. Definitely a trend to a colder more wintry possibility.
TW
The canadian is showing more of what I think will transpire with a low a bit further east that will transfer to the coast a bit quicker. At this time of year, I don't expect to see a surface low run up the tennesee valley as far as some models are showing. A much quicker transfer to the coast will happen (miller b style).
