LeesburgWx Posted January 20 Share Posted January 20 So ICON, GGEM, UKIE against GFS so far 5 Link to comment Share on other sites More sharing options...
DDweatherman Posted January 20 Share Posted January 20 If the euro does at 12z what it was cooking at 6z when the run ended, it’ll look similar to those UK maps. 4 Link to comment Share on other sites More sharing options...
Eskimo Joe Posted January 20 Share Posted January 20 12z UKMET is a legitimate HECS regionwide, just wow. The GFS really seems to be on its own thus far. It's over 24" for @HighStakes, @wxmvpete, @psuhoffman and @mappy. 5 Link to comment Share on other sites More sharing options...

winter_warlock Posted January 20 Share Posted January 20 If euro and Euro AI show what ukie showed them I think it's safe to say the GFS and it's partner the AI are outliers Link to comment Share on other sites More sharing options...
adelphi_sky Posted January 20 Share Posted January 20 4 minutes ago, LeesburgWx said: So ICON, GGEM, UKIE against GFS so far It comes down to does the GFS lead trends or follows? But I think going from around an inch of QPF to zilch in one run? Would this be the mother of all blips when other models are consistent? Link to comment Share on other sites More sharing options...
NorthArlington101 Posted January 20 Share Posted January 20 Ending my brief crashout - unless the EURO comes in and scares me. GEFS is fine. Drier. No real south shift. 10 1 Link to comment Share on other sites More sharing options...
WxUSAF Posted January 20 Share Posted January 20 Euro, EuroAI, GGEM, Ukie, and Icon are all phasing in the northern shortwave with some or all of the Baja low. So you get this extended duration event with coastal redevelopment that enhances snow in the RIC-PHL corridor and then lets NYC-BOS join the party. 11 1 Link to comment Share on other sites More sharing options...

It's a de-amplified run. To see the ensemble mean push 6"- 10" regionwide as a "fail" is still a sign of a potentially healthy event. 6 Link to comment Share on other sites More sharing options...

TSSN+ Posted January 20 Share Posted January 20 Anyone have the link to model verification? I want to see how bad the gfs is on a chart. Their used to be an ncep link but the one I have says it’s temporarily unavailable. Link to comment Share on other sites More sharing options...
MillvilleWx Posted January 20 Share Posted January 20 As @Eskimo Joealluded to above, the fact the GEFS is still showing warning level snowfall on a mean after what we saw from its deterministic partner is a positive attribute to have at this lead. The other guidance seems steady with its presentation which should also solidify the prospects for a MECS. Models can have hiccups and the GFS is no stranger to them. This is still a very good looking setup with some important pieces still not even fully materialized yet. We’ll see some model discontinuity on occasion until every player is on the field of North America and it begins to play out. If the EC suite comes in similar in its presentation last succession of runs, then it’s all systems are a go, still. 8 3 Link to comment Share on other sites More sharing options...

If you look at the ensemble members it's easy to see what's happening. The majority look a lot like the UKIE, CMC, etc. (although not quite as amped). But there are a handful of members that give us basically nothing - they all kind of look the same. I'm assuming these are the ones leaving the energy stuck back in the SW and missing any kind of phase. Those members are really skewing the average quite a bit. 2 1 Link to comment Share on other sites More sharing options...

One other item worth mentioning is that as we near an event, the "extreme" solutions tend to fade. If that happens, you see the few rogue 20"+ ensemble members come back to reality and that can tweak the ensemble mean downward. This translates to people thinking the event is "falling apart" when in fact it's just leaning towards a moderate/significant incident versus and major/historic. 2 Link to comment Share on other sites More sharing options...

GEFS didn’t really move apart from noise level changes. Op was probably one of the few members that held the sw back too much. 3 Link to comment Share on other sites More sharing options...

No real south shift. I was also having a bit of a crash out from some Feb 20th flashbacks with that GFS run. Though with the GEFS still looking that solid we're fine unless the Euro tries to ruin our lives. Just want to see the GFS move back to us at 18z and we'll be all good. 2 Link to comment Share on other sites More sharing options...

But generally I’d put the bar at 18”. The old rule of thumb is top 10 snowstorm on record. 1 Link to comment Share on other sites More sharing options...
