The 4 Seasons

thanks for posting this 8 years ago today. The fifth and last snowstorm of the season. A low end warning event for most of CT and Tri-State after the 4 nor'easters of March 2018. https://www.jdjweatherconsulting.com/apr-2-2018

29 years ago today. I posted these updated maps a couple months ago when we were discussing this storm a lot. Here's the link to all the maps and other images related to the storm. Also have a few radar animations https://www.jdjweatherconsulting.com/apr-1-1997

The majority of the historic storms have been updated with these new maps https://www.jdjweatherconsulting.com/historic-storms

With this dead March we've been having i had some time to work on the website and archive. I've updated about 70% of the historic snowstorms section and added new Lower Northeast view maps for those. I also created a new page for L. Northeast that will have all the events in that wide view. 2026 is up and 94-25 will be updated throughout the year. There's also a filter for contours only, all historic storms and storms >30" Website updates https://www.jdjweatherconsulting.com/historic-storms The 4 major storms of the 14-15 season

rough. dont feel bad i missed Feb 2013. And not only was that a major storm for CT, i am pretty much ground zero jackpot in that storm...

It's a pain to update these maps even for the most minor of changes but i couldn't let this be for Orange county. Razor sharp cut off https://www.jdjweatherconsulting.com/jan-23-2016

any report from Jan 26-27, 2015? @snywx as well

I'm very curious to hear from Middletown @snywx that would help

Yeah that is a very close measurement for a storm like that with wind and moderate to long duration.. that's kind of why I assumed it was you. You can get variations of 3-4" in a storm like this in the same town if one person is just taking the average depth at the end and someone else is doing 6hrly clearing and both are valid. So i was surprised to see it so close.

The PNS has 11.6 for Highland Mills, i am assuming that was you. I have it on the map. Are you sure about 11.2?

Jesus 0.4 from Campbell Hall to 11.2 in Highland Mills

@snywx @CPcantmeasuresnow

I figured id get some comments from orange county folks. I had to almost completely guess over there as there were hardly any reports. I can add your 0.4 and if I could get more from the other Orange country posters that would help

do you remember the snow event before the big storm? I had no idea that was even a thing, i just assumed (wrongly) that there was even an accumulating event before Oct 29-30th. Only far northern Connecticut in the hills picked up accumulating snow. Norfolk 2SW 2.5" Oct 27th, 2011

I updated several storms in the 97-00 period, i've been going back and forth on whether to include E. Granby for Windsor Locks ob. I decided to just label it with asterisk for that period. About half the storms in the Historic Snowstorms section have been updated and have new L. Northeast maps. https://www.jdjweatherconsulting.com/historic-storms

I updated one of our favorite storms of this sub-forum, and one of mine as well. Got into the meat of it in the CT band that rotated and pivoted overhead with a final of 14.4". Only 24hrs before hand we holding out hopes that the NAM & RPM were right. But last minute positive trends turned this into a major storm for 95 and a historic storm for the NY/NJ metro area. https://www.jdjweatherconsulting.com/jan-23-2016

lol

Another thing i just discovered is that there was a moderate event BEFORE the major halloween snow bomb of 2011. I can't believe that. I have to re-do that storm completely because a lot of the coop and cocorahs data i used overlapped for both events. When i've been doing these extremely anomalous late or early events in Oct/Nov or Apr/May i usually assume there is no storms that overlap on almost the same day or day before/after. Clearly i was wrong to assume that. On Oct 27th 2011 there was a 0-7" interior event that covered the Worcester hills, Berkshires and bled into NW CT in the Litchfield hills.

The official number for BDL for that storm is 12.3" in the climo data. The PNS has 20.3 lol, which i threw out. I'm just using whats in the F6 which is 12.3 for that date. So do you think i should or should not use E. Granby for BDL from that period 96-00 when BDL is missing? It sounds like the answer is no.

it's just they release these to the public whom take this very literally.

well this didn't age well

advisory is an average of 3" over a county and warning is 6". For Litchfield it's 4 and 7" respectively.

Yep, i noticed that as well. Winthrop COOP was identical to BOS in virtually every event. Same thing with BDR for a long time, over a decade. The Trumbull COOP was identical to BDR which means the BDR ob was not taken in Stratford itself i guess and actually in Trumbull? Or vice versa. It's impossible for me to know for sure where these obs are taken at each airport and how they've moved or changed over the years, so i just place the ob right over the town that the airport is in and for BDL that's Windsor Locks and BDR is Stratford.

Yeah, would way rather have it this way than the other. On paper 17-18 was good but the majority of the snow fell from Feb-Apr. Same with 04-05. 10-11, 13-14 and 20-21...also very good winters that had a dead March. Last good March we had was 2019 that was right at the beginning. 2018 was the last real banger.

really? that's a high bar. I think i got the significant wording from the benchmark that the NWS has used forever. 6+ = warning snowfall and the wording in the watches and warnings usually includes "significant". And before they switched to "light, moderate, heavy" accumulations in the zones it used to be "significant" for anything that would meet warning criteria. So i personally use moderate for advisory and significant for warning level or higher which that storm in Dec definitely was. It's all subjective and personal opinion though.. Yeah Jan 03 sucked here, there was a tight gradient in CT though. Similar to the christmas blizzard. Dec 03 and Jan 05 i lump into the same bucket of a long duration shredded radar mess. They were both pretty bad. Dec 05 was wild but still way better out east about 6-12 for most of CT
