yesterdays 12Z and the total snowfall - to gain any confidence we need consistency - a few runs in a row of the same solution

0Z Euro - yesterdays 12Z GFS was similar in amounts BUT we need a few runs in a row of this from more then 1 model to gain any confidence in coming days IMO

0Z GFSv16

0Z GFS north again for next weeks event - no real redevelopment before it encounters any blocking

The EPS and GFS both showing around 10 inches in the same location - interesting............

problem is that 2nd wave gets shoved south by the block - at least the models have reintroduced the idea of significant blocking and a stronger HP in southern Canada

Good idea - FWIW the 12Z EURO has an initial wave for Monday and then another to follow

yes different then both GFS and CMC with the temps especially

12Z GFS - just for fun --- and then the not so fun CMC

yes to try to get it right 200 hours in advance is a great challenge BUT as we close in on it it will get less and less challenging IMO - we have been through this many times since these forums started a long time ago

ok then to be fair why not trust the 12Z CMC - a complete miss to the south ?

and the 12Z GFS threaded the needle perfectly

and it does redevelop and slide off the coast

12Z GFS Continued you would think at this point with the LP encountering resistance from the blocking it would redevelop off the coast

12Z GFS

The models are all over the place with next weeks event - was surprised that the EURO went from a miss to the south at 12Z yesterday - to last nights 0Z lakes cutter agreeing with many other models that the block is basically a non factor with no redevelopment south of us along the coast.And then the EURO ensembles are south ?? Also the timing start is questionable - is that 12 pause in the event even real on the surface maps of some models ? Along with the early Monday morning start time ? Too many questions here and not enough answers yet IMO. Won't even get into precip type issues as the track of the storm being a major question mark at this time will basically decide the main precip type in any given location around the metro. I think just a general winter storm thread covering the 25th thru 27th with a details to follow description headline is an idea IMO - also there will be several adjustments in the details as the week wears on IMO....

0Z GFSv16

0Z GEM

we are still slightly above normal in the metro so far only need a few inches the rest of the month to stay above normal for the season - also note the lack of lake effect snow this year caused by the lack of any real arctic air so far. Also below normal so far in parts of the Ohio Valley .

12Z Euro looks like Canadian - a miss south mostly

12Z GEM basically a miss to the south for most of the metro - GFSv16 hasn't started running at 12Z for whatever reason as of 11:59 am

12Z GFS -redevelops off coast but too warm

corrected it to PD 1 - also that was a La NADA season El Niño and La Niña Years and Intensities (ggweather.com)

ALSO WELL KNOWN AS PD 1............and up to that point NYC had accumulated close to the same amount around 10 inches as they have had so far this season....
