beanskip Posted January 8, 2011 Share Posted January 8, 2011 Main difference between 0z at 48 and 18z at 54 is 0z is about 100 miles faster (east). Link to comment Share on other sites More sharing options...

FoothillsNC Posted January 8, 2011 Share Posted January 8, 2011 Atlanta is right in the heart of it at 60, with very heavy snow rates it looks like. Already .75" and cold enough for snow on this run, the 850 is far south.. Looks like a tight gradient on the north shield Link to comment Share on other sites More sharing options...
packbacker Posted January 8, 2011 Share Posted January 8, 2011 I am sure this was pointed out, but I couldn't find it, on the 18z GFS the 850 low looks to be in a better position at 72 than compared to 18z NAM or 12z GFS. Worlds different. 18z GFS 18z NAM at 72 Link to comment Share on other sites More sharing options...
QC_Halo Posted January 8, 2011 Share Posted January 8, 2011 Come on now, you know that isn't allowed. She has 2 posts so maybe she doesnt. With these events there are always new posters who dont know better. Probably best to send them a PM and for mods to reiterate the rules in the thread from time to time. I think they do a good job and for the most part things stay on track. back to lurking. Link to comment Share on other sites More sharing options...
phil882 Posted January 8, 2011 Share Posted January 8, 2011 Strange that the nam started out more amplified but then really dampened things out as it went later on into the run... not sure if I buy that, especially since the 500mb low to the northeast is further out of the way, which should allow for more amplification, not less.

Wow Posted January 8, 2011 Share Posted January 8, 2011 0z NAM a rotten egg for NC. s/w weaker and less amplified. that's the kill shot for NC. Link to comment Share on other sites More sharing options...

FoothillsNC Posted January 8, 2011 Share Posted January 8, 2011 Not much precip makes it to NC this run, atleast through 69 hours. This area is about .10" and theres a little more toward extreme sw NC near the GA border. Link to comment Share on other sites More sharing options...
DaculaWeather Posted January 8, 2011 Share Posted January 8, 2011 That's so pretty. But... it appears the heavy precip is further south than the previous runs. Link to comment Share on other sites More sharing options...
beanskip Posted January 8, 2011 Share Posted January 8, 2011 No kidding. I looked at the 700 RH first and said to myself -- hey, this is going to look just like the 18z. Then ... not so much. 0z NAM a rotten egg for NC Link to comment Share on other sites More sharing options...
FoothillsNC Posted January 8, 2011 Share Posted January 8, 2011 This run looked further south with everything, slightly. LIke Wow said, rotten for most of NC. Major snow for Atlanta and Birmingham and just north of those areas, but tapers quickly. Link to comment Share on other sites More sharing options...
Gastonwxman Posted January 8, 2011 Share Posted January 8, 2011 Erk. Someone dropped the death bomb on the precipitation before it got to NC it looks like. Still, like Phil said, it doesn't look right with the way it gets dampened out so quickly. Link to comment Share on other sites More sharing options...
jburns Posted January 8, 2011 Share Posted January 8, 2011 No kidding. I looked at the 700 RH first and said to myself -- hey, this is going to look just like the 18z. Then ... not so much. If the GFS and Euro come in tonight showing the same thing I think those of us up here in NC are going to have to face the reality that this will not be our storm.

Lowpressure Posted January 8, 2011 Share Posted January 8, 2011 Not buying the precip stops at the NC/SC border for 12 hours. Something doesnt look right, should amplify a bit more than shown Link to comment Share on other sites More sharing options...
Wow Posted January 8, 2011 Share Posted January 8, 2011 No kidding. I looked at the 700 RH first and said to myself -- hey, this is going to look just like the 18z. Then ... not so much. It's all in how fast the s/w dampens out. Though if it's too strong, then you get into mid level temp issues. Link to comment Share on other sites More sharing options...
MotoWeatherman Posted January 8, 2011 Author Share Posted January 8, 2011 0z NAM is still a fantastic run for GA. But we get another shift with another run. 18z NAM shift north and juicier on QPF while 0z pulled the heaviest back south just a bit. But still plasters the entire metro area and all areas north of Newnan/Lagrange with 6+" inches or snow. The bulk of precip looks like snow.

beanskip Posted January 8, 2011 Share Posted January 8, 2011 Look at how far the s/w moved between 42 and 48 hours -- from then on, it was just flat (in more ways than one). Link to comment Share on other sites More sharing options...
Pilotwx Posted January 8, 2011 Share Posted January 8, 2011 Folks, in NC a system this size does not just disappear ! The models are not catching on in the later time frames. Every run or the past 2 days the moisture over TX has expanded and lots more QPF. Tomorrow afternoon runs will be the ones I'm waiting for to see if a north and west trend start! It may not trend north and west but that has been the trend so far this year. Link to comment Share on other sites More sharing options...
Huffwx Posted January 8, 2011 Share Posted January 8, 2011 Not buying the precip stops at the NC/SC border for 12 hours. Something doesnt look right, should amplify a bit more than shown The SW dampens out, but there are also MAJOR dry air issues east of the appies.

MotoWeatherman Posted January 8, 2011 Author Share Posted January 8, 2011 NAM sounding for ATL supports snow thru 10am Monday with a change over to sleet sometime before 1pm. But by that time the bulk of the precip will have happened as snow. Link to comment Share on other sites More sharing options...

MichaelJ Posted January 8, 2011 Share Posted January 8, 2011 If the GFS and Euro come in tonight showing the same thing I think those of us up here in NC are going to have to face the reality that this will not be our storm. Yeah we had two chances at some snow, tonight and Monday, and tonight's is a fizzle and Monday is not looking good for the Old North State. Oh well, at least someone in the south will get a good storm. I am surprised how fast and complete the s/w dies off though Link to comment Share on other sites More sharing options...
FoothillsNC Posted January 8, 2011 Share Posted January 8, 2011 The upper levels warm around midday MOnday in southern NC near the SC border so if we don't get our snow by then, (and it is precipitating lightly then), we won't get much snow , on this run. Definitely not a good run for NC, but very good for SC and points west/southwest, with a big snowfall in Atlanta and northern Ga to Alabama.
