apologies if you’ve already done this but since you have 30 yrs of seasonal totals, would it be possible to make a 30-yr average?

I only have 25 years and it's on the site. I still gotta go back and not only fix and update all the seasonal maps but do ones for 94-99. Season total maps are pretty much non-existent pre 2008 so i have nothing to base it on except the COOP data and climate sites. They are rough and just meant to give a general idea of the season. 

But i did do an average for 25 years when the archive only went back to 2000. 

There's also NWS maps for each climo 30-year period.

I'm fully caught up on the archive for this current season with 12 3"+ events and every single event mapped out in the snowfall maps sections if it didn't make the main archive.

I set up a dedicated page for Winter 25-26. The SNE snowfall maps page has 23 events so far that required a map (>1" for an area)

Also all the season to date stuff is on that page as well, probably do one more final update to that in April or early May.

Didn't realize i missed a very large coastal storm that clipped SE MA before Boxing Day 2010. I didn't know about that one. I'll have to do that one and add it

Have you gone through the old box saved map and text archives to make sure you didn’t miss any?

That 2010 storm before Xmas was actually a retrograde job. Backed in from almost the E or ENE. Got us a white Xmas in ORH. Cape got croaked but we had something like 2” or so.

Yup looks like it was separated into two parts on the 20-21st and the 23rd. The pns lists it as two separate events even though it was part of the same system.

I did. I used that as a guide back to 2008 and also used the F6 for EWR BDR BDL and ORH. And then checked pns and coop/cocorahs for those dates that showed snow and my memory as well. 

Oh and Ray's winter storm archive

I think i just didn't include it in the main archive bc it didn't affect CT with any snow >3". I am going back and filling in all the missing storms in the SNE snowfall maps pages (every N MA, E MA, S NJ only storm). There's a lot.

Working on a weather analysis for the late Feb to early March 2023... Checked out your site, but did not see a map for a Feb. 27-28, 2023 event; appears to have been widespread 4 to 6 inch amounts across FF and NH counties in CT...

? It's there not sure how you could miss it

It's in the main archive and all the snowfall maps pages

[The 4 Seasons]

That was the only widespread adv snowfall that season

You can miss it when you accidently click on 2002-2003 instead of 2022-2023... lol   Also, a function of trying to concentrate on writing reports after 8 PM!  My apologies... As always, nice work...

Yep. Clinch Leatherwood was notable…he was the original Messenger on WWBB. RIP…we lost him in 2015 but his legacy lives in everytime we mention the Messenger Shuffle. 
 

I also recognize so many names that just drifted off the board over the years but were pretty consistent posters on here.

Fyi here’s the old snowstorm PNS/map list from BOX if you want to cross reference to make sure you have all of the events

I found the one from OKX that they deleted as well. Can't click on the links but i can at least see them

i finally found this stat! i always remembered and referenced these numbers but never knew where i saw them. Boston is about 1/3 seasons for a 12"+ event, ORH is about 1/2 and BDL is 1/4 and NYC though not on that list is about 1/5. I'm sure these went up considerably since 1992, probably by a lot.

They are up a ton since those were published. I have a spreadsheet I did that goes I think through 2018 or 2019. I’ll post the frequencies when I’m back on my work laptop. I think I did them for BOS and BDL too. 
 

I think ORH averaged roughly one 12”+ per winter in the last 30 years or so. That basically doubles the previous frequency. To be fair, that 1992 cutoff is brutal in the old averages….youre including the 1980s and those early 1990s years in there without the benefit of having those big 1990s years in there.

Wow to Both. Christ where did you find that old link, @dendrite? I’ve been looking for that.

Almost the whole internet is saved on archive.org. Just enter a site and click the old links that the search crawlers saved back in the day. I just picked a random year and date and clicked through to the climo section.

Unfortunately the saved forum data is hit or miss. But there’s some eastern and wwbb threads in there if you dig. 

[CCHurricane]

Just getting around to seeing this thread. Phenomenal job.

Should you ever need assistance with web-hosting costs, please let the forum here know. Myself and I'm sure many others would be happy to pitch in.

I found ORH from our discussion above...I don't have BOS or BDL at my fingertips but I know it's somewhere. They follow the same general pattern but just lower frequencies. 

 

Frequency = # of events per winter

2 foot+ per season in ORH is wild, they really do grow on trees there.

How do you calculate this? And what i mean is how do you know when an event 3+ or 6+? Say for example if the daily climate data had 5.9 on one day and 0.3 the day before? Is that 0.3 from an unrelated snow shower early in the morning or was it 0.3 just before midnight and connected to the same storm. Is it a 3-5.9" event or 6+ event? I know a lot of storms are spread across 2 days, sometimes 3 so im curious how you'd figure that out. unless you are using your memory and cross checking radar and other stuff...i feel like this would be difficult to do beyond what one can remember.

Just doing daily X-amount is easy, but by "storm" its a lot more difficult...unless you're keeping track in real time except for the 50s-70s.

Most of these systems were able to be found in PNS data if they were recent. For stuff prior to 1997 (which is when PNS data cutoff on the old BOX page), I'd generally use 2 day totals if I wasn't sure, but I did remember most of the late 80s to mid 1990s events so I'd know if they were separate ones (like December 6-7, 1996 for example). Most of the time, your numbers won't be affected if you solely used 2 day totals....you might get a rare instance like the Dec '96 example....but most of the time your bin won't change if it's adding a rogue few tenths from a snow shower...the only way it would matter is if it made a 5.8" storm into like a 6.1" or something like that....but even then, you aren't really going to be that far off the mark if you accidentally included a 5.8" event in the 6-11.9 bin. 

 

Most long duration events I already knew about too....late Feb 1969, Nov 10-12, 1987, Dec 20-22, 1975, etc.

The internet archive is a beautiful thing and total non profit organization like Wikipedia. It crawls the entire web, you can even find our little site on there and see the progress and how its changed over time.

I never even thought to look at it for these past events pages that have been taken down over the years from OKX and BOX. It's shame the NWS don't have the server capacity to keep them up. That's why a lot of their stuff is offloaded onto IEM (Iowa State) where you can find pretty much every product from the past.
