There seems to be a consensus among the GFS, NAM and ECMWF that the best time for accumulating snow at TTN is 0Z-3Z as the lower end of the deform band swings through... this is similar to what happened on 2/5/01 where essentially the same thing occurred, though a few hours earlier.

Quick question: is this a sign of things to come, or is it like '08 when we got that October snow and then nothing the rest of the year? I haven't had a ton of time this year to check out winter prognostications--i.e. La Nina/El Nino/teleconnection forecasts and the like.

We had two significant snowfalls afterwards...early Feb and early Mar. It wasn't really "nothing" considering the prior winter sucked.

October snow has little correlation with the rest of the winter. 79-80 was "ok" -- 02-03 (which had snow) was great, 08-09 was normal.

We even had a trace in October '72...the "snowless" winter.

TTN had 2.5", their biggest storm of the winter.

It does seem as though most October storms are followed by average winters at best.

Latest models show intensification around LI- would account for deformation band swinging through our area.

There were some winters in the 60's that did well...it's not a clear cut correlation.

Trenton got screwed a good bit in 08-09...but it wasn't an utterly awful winter for Philly or Lee. whistle.gif

The three Octobers with measurable snow at PHL, subsequent snowfall those winters were 18-29". Didn't snow at PHL itself in '08, but that winter too was within that range.

In my database for Chester County since 1894...only one October (1925) had snow = 3.5"

Would seem we have a shot to surpass that tomorrow. Kinda unfortunate I am here in Sea Isle at less than 10 feet above sea level....not thinking I see a flake here. Don't plan on being here for any "in winter" storms this year!! I know Greg (WhiteMtn) is looking out for the higher spots in Chesco and will keep us updated

I will update the Wxsim for NW Chesco in a couple hours

Should be fun tracking over the next 24 hours

Will do Paul. I sit @ 700' and can walk to 1000'. That might make a big difference early but if we catch that def band like Glenn seems to suggest in that forecast graphic, elevation won't matter as much. My property is somewhat rural and the area is heavily wooded so that is my primary concern. Electric often is lost and we're among the last to get it back. Either way I'm sure pics will be in order tomorrow!
