I agree, although with the caveat that delayed storm development has been a consistent issue this winter. Could turn out more of a coastal threat. The good news about the 6z GFS is the high is in a great position. The only reason it warms so much is the LP is weak, there's hardly any precip and it's mid-day as the low is pulling away
Models are converging reasonably well considering we're still 4.5 days out. I feel pretty good about the spread at the moment, with the caveat that a moderate/heavy all snow event is definitely a bit of a long shot
Duration is the biggest factor. Most significant ice storms are at least 12 hours of precip and usually not particularly heavy, but consistent. So overrunning events tend to be the highest potential
The cold push is pretty stout, with a dry airmass (this a few hours before onset) This would yield a wet bulb temp of 30 degrees with cold continuing to push in
Some of the disagreement about in-situ CAD comes down to different Climo dictating the outcome. Pretty good setup for ice in the Western Piedmont/SC upstate (although probably more moderate than major ice storm), much more marginal for our many wake county posters
Yesterday the placement was looking better. Just look at the trend on the GEFS. Any amount of amplification will push the cold out in a hurry.
If the low can slow down and remain to our South like the Euro depicts however, mid levels may not torch so much and we may stay frozen (at least in the Western Piedmont)
Euro gets frozen precip in the area, but about 24 hours later, so not nearly as good a look with the high having retreated to the east significantly more than the GFS
One thing to keep in mind is the radical difference between the way the GFS and Euro handle the next frontal system (at around hour 84). I have a feeling the Euro won't look anything like the GFS due to the downstream implications. It's going to take a while to iron this one out
I wouldn't say I'm excited, but this is a weather board and I'm interested in weather, regardless of the degree to which I enjoy it. Ice storms are fascinating from a meteorological perspective, even if they are the saddest of frozen precip types
The Euro on board with the storm idea. Model consensus at the moment is mid-levels will be a struggle, but as others have said, CAD may rear it's ugly head
I know RDU Climo sucks, but crazy that 3"+ storms only occur about every 2-3 years.
Question: how did you compile the data for multi day storms? I've been meaning to do a similar analysis for Greensboro, but only find day snowfall data out there.
