Ian Posted November 27, 2012 Share Posted November 27, 2012 It's not a storm until mitch posts the water vapor loop. back in the day of vortmax, wv loops were the only guidance from 3 days out. every now and then you find howard off somewhere trying to do that too.

mitchnick Posted November 27, 2012 Share Posted November 27, 2012 Let the radar hallucinations begin . meh, it will just be more rain, but the bulk of the precip does seem to be focused south of where the NAM has it Link to comment Share on other sites More sharing options...
Ian Posted November 27, 2012 Share Posted November 27, 2012 meh, it will just be more rain, but the bulk of the precip does seem to be focused south of where the NAM has it the nam is bunk. at least for those up north getting excited. it's probably nam'ing up the precip as usual. cut it in half and divide by 8.

ravensrule Posted November 27, 2012 Share Posted November 27, 2012 meh, it will just be more rain, but the bulk of the precip does seem to be focused south of where the NAM has it Might give us a chance of a stray flake if we can get in the heaviest precip.

psuhoffman Posted November 27, 2012 Share Posted November 27, 2012 sref doesn't really support it .. maybe a few spots to .5ish .. keeps main bulk south of long island etc. it's sort of on its own tho im sure some are throwing hour long parties in other subforums. not sure I agree... the latest SREF definitely juiced up some and trended north. If I was in places like Reading PA I would be on the lookout for a surprise...somewhere in there could get 6" I think. Over towards NYC not so sure...surface is really warm.

If I was in places like Reading PA I would be on the lookout for a surprise...somewhere in there could get 6" I think. Over towards NYC not so sure...surface is really warm. i only looked at the last sref.. don't think it's quite what the nam is and was also referring to the northern areas that have much less support right now like SNE/NYC etc. that whole se pa area has been much more under the gun consistently in modeling. it's not unprecedented for a storm to over-perform to the north of here so it's not like the NAM can't be right but i would at least want to see other 0z guidance go there first.

Ian Posted November 27, 2012 Share Posted November 27, 2012 GFS is .25"+ but no 1/2" areas looks wetter than 18z.. i think the nam is probably onto some maxes getting into a certain area but good chance it's too widespread in coverage etc. Link to comment Share on other sites More sharing options...

BaltimoreWxGuy Posted November 27, 2012 Share Posted November 27, 2012 This is a program called weatherscope...Created the map myself....Basically my thinking is, south of the red line (dewpoint 32F line), your already done for the chance of snow accum...this will likely still rise north...Best chance of accum will be north of wet bulb line 32f (green) that will probably drop slightly south.
