30-year Winter Storm Archive

[The 4 Seasons]

I'm very excited to share this massive project i've been working on since the end of last winter. I was going to wait until it was basically done but Seymour Snow kinda let the cat out of the bag yesterday, which is totally fine...the site's been live. We now have a winter storm archive with every moderate 3"+ event from last season back to 1994 complete with snowfall maps for Southern New England, Tri-State and CT as well as a full radar animation and surface and H5 maps. There's over 270 storms in the archive. I'm currently in the middle of the 95-96 season and updating the site almost daily. 

Winter Storm Archive

The significant (12"+) storms have their own page to easily view at a glance if you only want to see the big ones and don't remember when they were in the archive. I've added additional related images, satellite, radar and more to these larger events. 

Historic Storms Archive

There's also a section for only the snowfall maps sorted by region then by winter season (back to 94-95). Just go to the area you want to view, Southern New England, Tri-State Area or CT then click on the winter season you want. There's additional snowfall maps here that aren't in the archive that are either less than 3" or ones that only affected northern MA or southern NJ. Here you can also sort by 12"+, 24"+ or early/late season storms. 

Snowfall Maps Archive

25-26 events and maps will be added to the archive as they happen for the upcoming season. There's already 2 minor events in the Southern New England section. Will was a huge help with providing some archive sites like NCEP and Cornell Climodv2. All maps use data from COOP, cocorahs, NWS PNS and here. Everything is free and we don't run any ads. There's a download button on the images if you want to save them. As i mentioned the site is continuously being updated and added to. I'll probably do a thread like last year for all the SNE snowfall maps for all events. This was a huge passion project that i started years ago but really ramped it up this year so i hope yall enjoy it and find it useful.

Five star review.
 

Love being able to check out any storm or winter season with the click of a button.

Thanks, one more thing i wanted to mention. The radar from 2003-present is from IEM (Iowa State) where you can create and save to a gif but 2002 and earlier is from NCEI interactive radar that cannot be saved and you can only view one still snapshot in time. So to make those i had to capture images, frame by frame import them into photoshop, crop and sort them and make an animated gif or .mp4 video file from those frames, which was the most tedious thing you can imagine....each storm is 100-200 frames (Mar 4-6 2001 is 400 frames). But i think it's really cool to see the radar of these old storms, that were once lost to time, in an animation.

Truly excellent work. Thank you!

Amazing job! Thanks guys

I respect the effort. It takes a long time doing an analysis on one storm. You did it for 200+ events and manually conducted/plotted an interpolation. That's wild.

Hats off to you and your team for putting this together!

Even from NNE, that was good to click through and see.  Graphics are great and that must've taken a ton of work to make happen.  Kudos.

[HIPPYVALLEY]

Wow, amazing!  Thanks for all the hard work! 

[Chrisrotary12]

This is unbelievable. Thank you for doing this.

[CoastalWx]

I’ll have to check it out. Thanks for posting this!

This is amazing.  Even putting the titles on each storm reference represents a lot of work, and is super helpful.  High regards to all involved - great job!

This is great. Thanks!!

Wow, this is very impressive. Thanks for putting this together. I only had enough ambitions to do some seasonal maps and a few bigger storm maps. Doing most major storms for this long of a period is not only very impressive, but it excellent for preserving good records of storms. As the memory of those storms fade (and sadly the people who remember those pass on), we only have whatever was archived to look back on.

This is awesome!!

Wow, i did not expect this amount of overwhelmingly positive feedback. It makes it worth it to know how many people enjoy it and find it useful. I started this project back in late 2022 but only focused on Connecticut. At the end of last season i found two sites that archived radar, as well as the NCEP/daily weather maps site for sfc/h5 and with the recently made SNE/Tri-State maps i knew what i wanted to do. Got to work in February and this is where im at now, mid 95-96 season. I'll be adding a lot more stuff, including the current season and finishing back to 1994.

Thanks man. That Cornell climod2 site is priceless especially since it pulls from cocorahs, coop and others. i recently found this upgraded version xmACIS2 that donsutherland1 sent me and im using that now. You can view the station type, station coordinates, elevation, county and more with this version, it's super helpful.
