Wintry December 28-29th Possible Winter Storm

Poor Larry gets NAM'd yet again on this run. Even if you cut these numbers in half in coastal GA, still talking at least 0.25" of ice, more than enough to start leading to widespread power outages... Some ZR even makes it to the Macon area

We have done this song and dance from the 12z run....but It is a pretty big upswing in the qpf shield, but def. an upswing in qpf amounts from 18z run. Again its the nam.....prob. all on its own, but we shall see if there is any other support for it.

Yea we'll see. Regardless, I think it'll be hard to rule out (barring temps don't end up warmer than forecast near verification or this storm doesn't get suppressed a lot more) that some patchy light freezing drizzle or light freezing rain showers are abound in your neck of the woods. Those are nearly impossible (even for 1km models like the Swiss) to resolve this far in advance, much less at just about any time until it's almost on top of you...

I agree. I still think a nice little glaze is possible here. It won't take much.

Wowzers and 0.60" IN Charleston...lesser in the inland coastal counties...whoa
 
The last breaths of the 28th system for most of forum in next few runs...

Although tonight's system definitely makes you wonder...

NAM and GFS are barely different at 850mb and 700mb, yet the NAM sharpens up the coastal front and pops a 1015mb low where the GFS has no SFC reflection.

hey it will snow when it snows! model watching is just ridiculous! again it will snow/sleet/zr when it does! period!
 
all this model watching is soooo stressful! imagine before all these models how it must have felt to just look outside and see snow when you haven't spent days stressing over weather it would happen or not I think that kinda of surprise is the best
