Collegestudent11 Posted December 24, 2010 Share Posted December 24, 2010 Through 18 hours the NAM is already drastically different with the northern stream. Can you please elaborate? I see the slight phasing between the two streams, if that is what i am seeing and you are noting. Link to comment Share on other sites More sharing options...
tornadojay Posted December 24, 2010 Share Posted December 24, 2010 Through 18 hours the NAM is already drastically different with the northern stream. yea, you're right.. it is further southwest, stronger, and looks to be oriented in such a fashion to dig more.. let's see if it continues that way Link to comment Share on other sites More sharing options...
CooL Posted December 24, 2010 Share Posted December 24, 2010 The northern stream is diving in much faster than 18z thru hr 24.. Link to comment Share on other sites More sharing options...
earthlight Posted December 24, 2010 Share Posted December 24, 2010 yea, you're right.. it is further southwest, stronger, and looks to be oriented in such a fashion to dig more.. let's see if it continues that way Yeah. The northern stream is much further southwest this run...hundreds of miles difference. The shortwave over TX is also a slight bit slower..and the ridge out west is stronger as well. Will it have a big impact? Probably not..but any changes in the positive direction are good considering we are walking a fine line between nothing and something at the moment.

Probably not..but any changes in the positive direction are good considering we are walking a fine line between nothing and something at the moment. Certainly substantial difference- wouldn't be surprised if this looked like 18z GFS. Link to comment Share on other sites More sharing options...
Dsnowx53 Posted December 24, 2010 Share Posted December 24, 2010 To be fair, if we saw these drastic changes on the GFS, it would mean more. On the NAM, we further away from a good solution for coastal areas than we are on the GFS. Link to comment Share on other sites More sharing options...
earthlight Posted December 24, 2010 Share Posted December 24, 2010 A small piece of the southern stream shortwave already phased in at 21 hrs...but by 27 hrs the main shortwave is still very far southwest and the northern stream might leave it behind if it doesn't get a move on.

Yeah it almost looks like the main shortwave becomes strong enough to just do it's own thing and lag behind instead of riding around the trough.

greg ralls Posted December 24, 2010 Share Posted December 24, 2010 Thanks bro, didn't realize there was another retro Eagles avatar out there. Sorry to copy, but it's really cool. I was just remembering the other day the kelly green Eagles coat I had in the 80s with the hood that unzipped and laid flat on the back and the embroidered logo on the front. Here's to a faster phase at 0z! No, I think it's totally cool. I loved the kelly green as well - wish they would go back to it, actually. Anyway, to get back on topic, I'm definitely hoping for that with the next model runs as well! Link to comment Share on other sites More sharing options...
Edge Weather Posted December 24, 2010 Share Posted December 24, 2010 Sharper ridging and stronger upper level low over Texas on this run. More interesting definitely. Link to comment Share on other sites More sharing options...
_AR_ Posted December 24, 2010 Share Posted December 24, 2010 now at 39, it almost is looking like it did last run again Compared to 18Z, trough is wider and heights are slightly higher along the east coast. Link to comment Share on other sites More sharing options...

_AR_ Posted December 24, 2010 Share Posted December 24, 2010 Wider trough? That doesn't sound better. Actually it might just look that way due to the higher ridging on both sides. It isn't much broader. Link to comment Share on other sites More sharing options...

earthlight Posted December 24, 2010 Share Posted December 24, 2010 It's going to try to catch it with the second northern stream feature at 48 hrs, I can tell you that much, but I don't know how much good it will do anybody away from the Cape or coastal New England.

_AR_ Posted December 24, 2010 Share Posted December 24, 2010 It's trying, man. It really is. Hr 42 higher ridging along east coast continues. Link to comment Share on other sites More sharing options...
ctsnowlover Posted December 24, 2010 Share Posted December 24, 2010 western ridge sharper at 42 hrs, may still be OTS but will come further north i think Link to comment Share on other sites More sharing options...
dryslotted Posted December 24, 2010 Share Posted December 24, 2010 the trough looks deeper and more neutral (at least less positive) than at hr 48 on the 18z or at hr 54 on the 12z Link to comment Share on other sites More sharing options...

Ridingtime Posted December 24, 2010 Share Posted December 24, 2010 Is anyone bothered by the obvious lack of precipitation with the southern wave at 48 hrs compared to the 18z? Link to comment Share on other sites More sharing options...
Snow_Miser Posted December 24, 2010 Share Posted December 24, 2010 NAM looks... weird... I'm not sure I buy this model run, or not. Link to comment Share on other sites More sharing options...
Edge Weather Posted December 24, 2010 Share Posted December 24, 2010 Yes, and is just seems to me that on every run it looks really good until out of the NAM's best range of around 42-48 hrs, then it dampens that southern stream wave, possibly too much? This run is so tantalizing..look at the vort max in the southeast states at 57 hrs Link to comment Share on other sites More sharing options...
tornadojay Posted December 24, 2010 Share Posted December 24, 2010 This run is so tantalizing..look at the vort max in the southeast states at 57 hrs that'll help bomb it out by dispersing the height contours and lowering the pressure.. I'm worried about the track. It still seems so far east. Link to comment Share on other sites More sharing options...
