weatherwiz Posted January 10, 2011 Share Posted January 10, 2011 I think GFS is going to be slightly more amplified based on 24 hour prog so far... Already neutrally tited with the trough at 24HR Link to comment Share on other sites More sharing options...
Clinch Leatherwood Posted January 10, 2011 Share Posted January 10, 2011 GFS and NAM in basic agreement with the height lines through 24 far as I can tell. Link to comment Share on other sites More sharing options...

Clinch Leatherwood Posted January 10, 2011 Share Posted January 10, 2011 GFS and NAM in basic agreement with the height lines through 24 far as I can tell. By 30 we're starting to see some differences at 500 particuarly up north...GFS not quite as robust by the PA/NY border and west by the lakes it's slightly further east. At least at 30 it's not as amplified as the NAM. Link to comment Share on other sites More sharing options...
Chrisrotary12 Posted January 10, 2011 Share Posted January 10, 2011 How come on 0Z NAM the 850 0 c temp line never reaches Chatham? Link to comment Share on other sites More sharing options...
weathafella Posted January 10, 2011 Share Posted January 10, 2011 MSLP about 100 miles south of HSE at 39 hours. Slightly SE of 18z position but it seems more of a timing issue and again...not huge differences as of yet. Link to comment Share on other sites More sharing options...
Clinch Leatherwood Posted January 10, 2011 Share Posted January 10, 2011 36 less amped than the NAM, but better than the 18z GFS with heights anyway. It's actually a little weaker in terms of distribution of peak units at 500. Who knows? Link to comment Share on other sites More sharing options...

MattdWX Posted January 10, 2011 Share Posted January 10, 2011 this is sort of off topic and I am not spamming but pretty much everyone on here is a lover of winter weather and FYI the Legend Paul Kocin is the banquet speaker at the Lyndon State College Storm Conference this year which is being held in March.

weatherwiz Posted January 10, 2011 Share Posted January 10, 2011 Looks a bit faster through 36 than the NAM...looks a bit more flat upstream too but the trough is slightly negatively tilted. Link to comment Share on other sites More sharing options...

Bostonseminole Posted January 10, 2011 Share Posted January 10, 2011 very similar to 18z, as you said Jerry, maybe a little SE.. Link to comment Share on other sites More sharing options...
Clinch Leatherwood Posted January 10, 2011 Share Posted January 10, 2011 Yikes by 42 heights are a lot lower than the 12z GFS... EDIT: As others said little better than the 18z GFS. Compared to the NAM placement etc very similar, just slightly lower heights. But this is the NAM witching hout so lets see Link to comment Share on other sites More sharing options...
Chrisrotary12 Posted January 10, 2011 Share Posted January 10, 2011 The low occludes before it comes ashore. And the 540 line sits on the canal. Which is further south and east than it was on 12/26 and I never flipped to rain or sleet here. Link to comment Share on other sites More sharing options...

Max Posted January 10, 2011 Share Posted January 10, 2011 Even if this run were to verify I'd be pretty nervous living in the CT Valley, low-level wind fields and sfc winds are mainly out of the N/NE...if you look north of us there is a pretty good amount of dry air; 2M dew points are around -10C or lower, 2M RH values aren't bad...between 85-90%, 925mb RH values the same but up at 850mb you have values less than 40% and a real sharp gradient of the more moist air and the really dry air. I'd be worried here if these winds would draw in some of this drier air and cut back on precip just a bit in the CT Valley. Why does everyone always want to bash on the Connecticut River Valley, it's not like there are 2000' mountains on either side of it in Ct. Ryan if you could, is the Ct Valley really a screw zone more often than not or is this just a myth? Link to comment Share on other sites More sharing options...

40/70 Benchmark Posted January 10, 2011 Share Posted January 10, 2011 I don't think it's early to be posting maps depicting 8-12"...that is very likely. GFS slaps the NAM down, as we thought; EURO to follow suite. Link to comment Share on other sites More sharing options...
