I'm really surprised no one here is commenting on short range models...

 

Still kind of far out, really.  Precip is still 18+ hours of range for most of us, so the short-range models do not cover it.  In addition, they are usually pretty flawed out in the 10+ hours range, it seems.  I'm sure we'll be focusing more on them tomorrow morning.

 

Anyways, eyes now turn towards the Euro.

Yeah it's maybe a .10 lighter on precip. Snow map seems to have the snow a little farther south but need to check on temps.

 

CLT and RDU are icy on this run.

 

Looks like we get a thump of snow to start, though it is impossible to say how much with the 6-hr panels.  Looks like we're at about 1/2" QPF compared to 0.6" last run, IIRC.

 

The Euro is definitely a low outlier on precip, it seems.  We'll see what happens.  Looks like the Euro lightened up some in C VA, too.

2-3" maybe? The 850s line is in VA on the 6z Tuesday panel so I'm assuming we probably only hold on a couple hours after 0z. It seems a little lighter on the precip everywhere but really for anyone who doesn't have access to maps just look at what was posted for 12z. It's not meaningfully different in any way.

Yeah, I would speculate that.  Looks like we warm up to +2C at the highest at 850 mb, so we probably stay sleet rather than freezing rain.

 

Who knows what will happen?  Some large differences in QPF exist across the modeling with the Euro showing ~.5" while some models show ~1".  I'd probably say that ~0.8" is most likely, as the SREF mean had.

It's definitely not Apps Running, so put that fantasy to rest.  It's basically identical at hr 21.  Maybe a hair colder... as in by like 5 miles, so not really. :lol:

not to say the RAP and HRRR correct, but conceptually it makes sense. I hope all the other models are right though. not leaning on RAP and HRRR till tomorrow.
