mitchnick Posted March 2, 2013 Share Posted March 2, 2013 Don't know if its useful to compare runs from different models. lol I know 90% of what we do is not useful and don't know about the other 10% Link to comment Share on other sites More sharing options...
WinterWxLuvr Posted March 2, 2013 Author Share Posted March 2, 2013 but too slow is bad I recall at least one, and pretty sure there were two, systems this year that slower was better but then it slowed too much and a GL low showed up on the scene a tough 100 hrs to come on this one I just hope it makes up its mind early on so I don't waste my time with it The NAM is slowing things down. Most people in the know here don't place any stock in the NAM at that range, but it does raise an interesting question. Does slower make an earlier phase more likely? I'm sure slower is probably better wrt the ne ull. Link to comment Share on other sites More sharing options...
Scarlet Pimpernel Posted March 2, 2013 Share Posted March 2, 2013 Bored, my friend. And anxious... For sure...aren't we all! If the 18Z GFS was at least in the ballpark of the 12Z solutions, we'd all be breathing a bit easier. But that really threw a monkey wrench into things after such good agreement in all the 12Z models, and after the GFS itself trended toward what the Euro was showing.

yoda Posted March 2, 2013 Share Posted March 2, 2013 GFS looks pretty similar through 48 on 00z compared to 18z with some minor differences on h5 lil slower at 57 and the the ULL is a bit further SE -- 00z compared to 18z Link to comment Share on other sites More sharing options...
wxmeddler Posted March 2, 2013 Share Posted March 2, 2013 Looks good so far, vort max comes near my favorite spot. Southern wave looks a bit faster this time around. Link to comment Share on other sites More sharing options...
Porsche Posted March 2, 2013 Share Posted March 2, 2013 How's the block looking compared to 12z? Link to comment Share on other sites More sharing options...
clskinsfan Posted March 2, 2013 Share Posted March 2, 2013 This times about a billion. If we assimilated no observations into the 18z assimilation, it would show the EXACT same solution as 12z. That's how it works, we don't start from scratch, we combined a model state with observations. For 18z, we have a ton of observations, notably satellite-based, surface and aircraft based sensors (domenstic passenger and cargo planes from various vendors). A 120-h forecast from 18z will almost always be better than a 126-h forecast from 12z. Great info. Thanks for posting it! Is the model run with the same resolution on all model runs?

yoda Posted March 2, 2013 Share Posted March 2, 2013 00z has the h5 low a bit broader at 75 than it was at 18z... but basically in same place in NE. Southern energy in just about same place Link to comment Share on other sites More sharing options...
wxmeddler Posted March 2, 2013 Share Posted March 2, 2013 How's the block looking compared to 12z? Stronger by a smidge but the vortmax is stronger and slower. Link to comment Share on other sites More sharing options...

WinterWxLuvr Posted March 2, 2013 Author Share Posted March 2, 2013 Looks to be more ridging in front of the 500 low. Someone who knows more can speculate what that does. Also slowing. Link to comment Share on other sites More sharing options...
clskinsfan Posted March 2, 2013 Share Posted March 2, 2013 The gradient in that storm was ridiculous-- 4" DCA to 11" Silver Spring to 19" Rockville to 35" (!!) Front Royal. Sounds good. Lock that up please. Link to comment Share on other sites More sharing options...

PDIII Posted March 2, 2013 Share Posted March 2, 2013 the 500 MB heights look to have the upper level low a little more closed off and slightly more north at 75 as compared to 12z Link to comment Share on other sites More sharing options...
lsukev Posted March 2, 2013 Share Posted March 2, 2013 ULL placement looks a lot like 12z so far to me. Less nosing towards the Great Lakes. I would think that would keep the NS vorts from not washing out. Link to comment Share on other sites More sharing options...
PhineasC Posted March 2, 2013 Share Posted March 2, 2013 On the whole debate on 18Z/06Z... I have been watching models for a long time and I am pretty sure those "off-hour runs" do more weird things than the 12Z/00Z runs. Yeah, maybe the folks at the NWS have stats that show at 500mb they are nearly as good as 12Z. And the UKMET is almost as good as the Euro even when it shows the low headed to Spain. For us weenies who look at the surface maps it isn't all that. Link to comment Share on other sites More sharing options...

WinterWxLuvr Posted March 2, 2013 Author Share Posted March 2, 2013 Huh?? I'm just looking at height lines. Look how much further south the 540 line is vs earlier runs. I'm not saying its bad. Truth is, I don't know. Link to comment Share on other sites More sharing options...
