Cold Miser Posted Tuesday at 12:42 PM Share Posted Tuesday at 12:42 PM On 2/5/2026 at 4:15 AM, The 4 Seasons said: @CoastalWx @Chrisrotary12 I updated all the maps for April Fools '97 as well as added a new Lower Northeast view map with all the climate sites on it. I also added that radar loop from BOX you posted in the other thread for this storm, and i sped it up a bit. Also refreshed all the maps for the March 3-4th, 2019 and December 1-3rd, 2019 storms + added the northeast maps for those as well. I think that Dec 2019 is one of the craziest looking maps i've ever done, quite a gradient and really cool to see that bending of higher snow totals towards the CTRV/91 https://www.jdjweatherconsulting.com/apr-1-1997 https://www.jdjweatherconsulting.com/mar-3-4-2019 https://www.jdjweatherconsulting.com/dec-1-3-2019 I loved that storm. I just moved into my apartment in West Roxbury the day before. Woke up to this epic storm. I think we ended up with 30". It was my first day taking the train to Boston from West Rox. I was surprised that the train was on time...until I was told that the train I boarded was 2 hours late from earlier. Link to comment Share on other sites More sharing options...
vortex95 Posted Tuesday at 06:24 PM Share Posted Tuesday at 06:24 PM I'll dig out of my archives soon booklets I have that summarize all snow events for SNE from the early 1970s to the mid 1990s. I'll take pix of the more significant ones, and send them along. Link to comment Share on other sites More sharing options...
The 4 Seasons Posted Wednesday at 08:26 AM Author Share Posted Wednesday at 08:26 AM Hey @H2Otown_WX could you help me out with something? There is notorious missing data from BDL from 1996-2002 on the F6 and climo data. However, i have this theory and suspicion i wonder if you could verify or deny it. There are a lot of reports from around that time on the PNS from BOS during significant snow events and almost always lists East Granby. Kind of strange that during that missing data time East Granby is always there but Windsor Locks is not. Did BDL once report from East Granby? When i checked on google maps Bradley International spans over both towns. So it would make sense that it was once reported as "East Granby" instead of Windsor Locks. Though that still doesn't explain why a lot of data is missing. Just a theory, thought you might know or could find out. Thanks. 1 Link to comment Share on other sites More sharing options...

Hey Dylan, I'm not sure what the situation was back then observing wise...I know in the 2000s and early 2010s we were at the terminal which is in Windsor Locks. In 2012 we moved to Signature Flight Support on the west side of the airport which is indeed in East Granby. I have no idea who would have been doing those measurements at that time though...probably wasn't a contract weather observer if I had to guess. Could it have just been DOT or something or airport operations people? I'll ask my supervisor about it. He started in 2000 I think so he might know.

I'm curious about that because like every PNS has East Granby as an ob, which after those missing years you rarely see. 1 Link to comment Share on other sites More sharing options...
dendrite Posted yesterday at 12:48 AM Share Posted yesterday at 12:48 AM That late 90s period was messy with the ASOS transition and observers were reduced. I’m pretty sure East Granby would be the BDL obs. The airport property runs into E Granby anyway. Link to comment Share on other sites More sharing options...

That was my suspicion as well, though it is never noted on any of the PNS from BOX during that time and the data is missing in the now data F6. Do you think it would be fair just to label those as BDL on the maps im doing for that time? Ill wait to see what @H2Otown_WX says Link to comment Share on other sites More sharing options...

The 4 Seasons Posted yesterday at 12:48 PM Author Share Posted yesterday at 12:48 PM I remapped and updated Feb 2013 Blizzard, Jan 2000, Feb 2007, Dec 2010 (Boxing Day) and Jan 2022 as well as added new L. Northeast maps for all events. 2 Link to comment Share on other sites More sharing options...
The 4 Seasons Posted yesterday at 01:12 PM Author Share Posted yesterday at 01:12 PM Just wanted to shout out similar archives that have snowfall maps for many significant storms that i never knew even existed until i started working on this last year, except Ray's which is very prominent. A lot of them were helpful in finding additional snowfall reports for past storms. I will add this to the first post on this thread as well. Snowstorm Archives Ray's Winter Storm Archive - NJ Mercer Co (PHI/OKX) focused, 1993-2013 Rutgers State Winter Storm Archive - NJ State (PHI/OKX) focused, 2002-present Steve LaPointe's Weathernet6 Archive - NY Capital Region (ALY) focused, 1993-present Eric Webb's Archive - NC (RAH) focused, 1885-present NWS Snowstorm Archives OKX Significant Weather Events BOX Significant Weather Events ALY Significant Weather Events PHI Significant Weather Events Significant Storms Reanalysis Tomer Burgs PolarWx Archive - Reanalysis of past storms 2 Link to comment Share on other sites More sharing options...
PhiEaglesfan712 Posted yesterday at 01:19 PM Share Posted yesterday at 01:19 PM Can you do 1992-93 and 1993-94, as both were really good snow seasons? The archive would feel incomplete without the Blizzard of 1993. Link to comment Share on other sites More sharing options...

The archive would feel incomplete without the Blizzard of 1993. It's here: https://www.jdjweatherconsulting.com/historic-storms That's what the historic storms section is for (one reason anyway) for big storms pre-1994. I'm going to go back and touch it up at some point. The reason i stopped at 94-95 is because NEXRAD WSR-88D is unavailable before Jan 1, 1995. So i stopped the seasons at 94-95. Technically there is one event in the 94-95 season, Nov 1994 that doesnt have radar because of that fact. On top of that there is no PNS reports from around 95-97 and earlier depending on the forecast office so reports are thin and it's basically just COOP data so i dont really feel that good about the maps before that time...they are rough and coarse. 13 hours ago, codfishsnowman said: This map is the best one yet for this storm. Your attention to detail is exceptional. Thanks. I do the best i can with hand made maps, it's never going to be perfect and there will always be small discrepancies depending on what reports you use or keep out. I try to use every resource available and throw out the bad data. It's all just one persons interpretation thats why you're never going to see two maps that look identical to each other for the same storm. The best ones are the computer generated ones that get fed data and spit out a hi resolution contoured map and factor in terrain. Tomer Burg probably has the best maps out there in my opinion. The NWS maps are also great but they don't filter out a lot of obviously bad data that gets ingested. Link to comment Share on other sites More sharing options...

It sure is, I was just looking at stuff from the 80's and 90's, all very well done for my neck of the woods. Link to comment Share on other sites More sharing options...
ORH_wxman Posted 1 hour ago Share Posted 1 hour ago The old East Granby reports are definitely BDL. At least most of them are I’d think of not all of them. There wasn’t an active coop there either. Link to comment Share on other sites More sharing options...
