There's no way the radar's going to look like that in 4 hours when it's ragged and showery as it is now south of us. Sorry, but that looks over done. As does the inv trough. The NAM's been over done all through this storm, why wouldn't it be now?

could not agree more-plus there's dry air being pulled in from the northeast....precip is going to have a slow battle moving north and especially northwest...

Until the hi res models lose this ,no one should throw it out.

 

Anth , I dont think you just toss it , but keep in mind the NAM just came off some really big runs in the last few days showing a pretty significant round 1 today  , and at 12z today the day of  , it backed off .

Its not about only the hi res seeing it , the NCEP short dated models prob run with the same capacity and close enough algos  ( im sure there are diff initial points ) but they are all updated only a certian amounts of times a day .so im not sure to what extent the NCEP short data differ .

 

RGEM I cant speak too ,

The Euro is updating all day , all nite . The Euro is somewhat has  hi res capacity , just because it has a long term feature its pretty good at picking up meso scale features a day away . AND IT DOESNT , see it to this extent . Its really a better tool  if it doesnt have it , you need be careful.

2 things to remember  Norluns love New England , they dont like us .

Secondly they usually arent as robust in size as the NAM is progging  , its usually very narrow and very intense

 

Just M O .

Nam is similiar to the ARW. SREF has about .50. That seems more likely.

for tonight, another .5 with the trough, storm total is close to 1"

 

it seems that besides the EURO we have consensus for around .5" liquid tonight from the coastal, however, I can't be 100% onboard without the EURO...

I fell for that with the 2/6/10 storm. The simulated radar looked great, especially out in PA, making it look like the heavier stuff would get into our area. And of course we know it didn't

The NAM verbatim is a MECS with this event.

So over the past day NAM has forecasted 30" for NYC. Bring back the ETA. NAM is just awful. 

Not a great performance for either the GFS or NAM here. NAM was way too juicy and looks to continue being that way, and the GFS continuously suffered from feedback problems and cut precip back too much as a result. But honestly, looking at the radar, the GFS seems closer to being right. It doesn't look that great over southern NJ right now and the crazy radar the NAM shows for tonight looks way overboard.

Upton cut back on their precip amounts from tonight into Friday. They have 4-6 inches areawide.

 

So they dont believe there own model 24 hours away  ? ... That should make you  feel confident .

Just be careful without the Euro . There arent too many smart guys out of the regional offices not buying that solution , thats  all im saying

Euro has 3-6 inches until Friday so they might be going with the Euro.
