The 4 Seasons

CC:

5 years ago. The December 17-18th moderate snowfall. A pretty much pedestrian and forgettable event but this time of year it's worth noting and something i'd kill for right now. I'd also kill to have this great radar back and not the abortion they're currently using (RIP flash).

2.2 puts me at #1 on the list for CT, i'm gonna bask it now since this rare circumstance won't last long lol

41F with some light rain here and there.

Man this storm really took a big fat dump on the subforum. At least i was never in the game, so there's that. We're off to good a start.

I'm definitely in that mindset that has been expressed here, if it aint gone snow and/or there's no pack to preserve, i could care less if its 40 or 60. XMas/Mas Eve 2014, 2015 and 2020 were in the 50s and 60s. Looking back i can't believe it was 69 in 2015, almost hit 70 on Christmas Eve, now that's a torch, tiger.

This is the one-year anniversary of the December 16-17th nor'easter that affected the tri-state area and New England. This storm was a major snowstorm and listed as a Cat 2 on NESIS. Snowfall ranged from 10-16" across most of CT and NYC. But the most notable thing about this storm is the huge positive bust the occurred over upper New York state, VT, and NH. Right up to the beginning of the storm many models had very low snowfall in areas that would end up receiving 2-3 feet or more. The highest totals also were reported in this area due to very high ratio snow in the deformation zone. Model trends in the 36-72hr range pushed the storm a bit closer to the coast and the eventual track would end up being inside the 40/70 benchmark. Here are some selected reports across the Northeast. The highest total reported was 44" in New York and New Hampshire. New York City (KNYC): 10.5" Newark (KEWR): 11.4" Hartford (KBDL): 12.3" Bridgeport (KBDR): 9.4" Boston (KBOS): 12.7" Worcester (KORH): 12.1" Albany (KALB): 22.9" Concord (KCON): 25.6" This was a somewhat long duration event with H5/H7 lows closing off. Precipitation began as snow at around 6PM across southern CT and slowly pushed northward. Moderate to heavy snow began a few hours later and encompassed all of Connecticut with rates approaching 3" per hour. After this initial thump pushed through a dry-slot engulfed the state as mid-levels dried out and as precipitation lightened up. Snow changed to sleet and freezing drizzle for much of the southern half of the state. The radar began to fill in again after 2-3AM and mixed precip changed back to all snow. Most of the accumulating snow ending shortly after sunrise as low pressure moved northeast. But it wasn't over yet for Connecticut. Gravity waves moved through in the early afternoon hours and dropped another quick 0.5-1.0" for many towns in southern CT. After these heavy snow showers moved through the state, accumulating snowfall would come to an end. The total duration of the storm was approximately 6PM to 1PM or 19 hours. Forecasting. Under most circumstances i would wait until approximately 2-3 days out to issue a first call on a winter weather event. However, this was the first time i would put out one 3-4 days out. Nearly all global models were very consistent with each other on a widespread 1-2 foot event and on top of that run-to-run consistency was also very high. That, coupled with the fact this was a pretty straight forward setup with plenty of cold air in place, made this an easy decision. From what I recall it was only myself and AMWX user 40/70 Benchmark that issued a map at this time lead. Because of this, a post I made on FB went viral with thousands of shares and likes in 24 hours. This was a few weeks before we launched our business, so it was just my personal Facebook account. The final call I issued was kept as-is with 12-20" for the entire state, emphasizing lower totals near the coast/SE shore and highest in the NW part of the state. This proved to be the case; however, totals were a bit lower than forecast. The state received 10-16 with 6-10" along all of the shoreline. This nor'easter ended up being one of the biggest December snowstorms on record for BDR and BDL. Locally in North Haven, it was the biggest I have witnessed since 2000 and possibly since I've been alive (Dec 30th, 2000, was close).

Huh? How so? i lived in the bay area, there is no interesting weather there. There's no severe weather at all. No canes or tropical systems. It never snows there. It's pretty much the same temperature all year long besides an occasional dry heat wave. Unless you're into rain storms in the fall/winter or maybe an earthquake, which isn't technically weather, I'm not sure how you could argue otherwise.

Right, and they'll get 10-12ft drifts on 3-6er event. lol

Coastal CA, like the bay area San Fran, LA or pretty much anywhere outside of the mountains has the most boring weather on the planet. It's like groundhog day all year round. If you're into weather or a met that lives there you probably want to poke your eyes out with knitting needle.

The SLP is clearly quite a bit north from 00Z but the run is overall colder, esp with the frontend thump in CT

did you call NCEP and tell them to fix that for the 6Z run?

I found one at 10K feet thats even more ridiculous. 89-115". And thats only for the first storm, to the end of the warning. Earlier i saw one at 12K feet that i didn't save but it was 118-155". I used to live in South Lake Tahoe and it this is a lot, even for them. A historical event.

CT State snowfall totals for the Dec 8th, 2021 event.

lol i just finished the map and saw this, i have to go back and change the overlays now, but thanks for the report im glad theres another 2+ report in the little blob area i made around north haven.

I'm doing a snowfall accumulation map for this little event so if you have final numbers please send them to me or @ me. Reports are sparse since it was a minor event, OKX didn't even put out a PNS, BOX and ALY did but they are very limited with only a couple reports. I can check CoCoRahs, they have some but i'd like to get the members on here. I combed through the last few pages and already have DIT, Ginx, Sugarloaf, FlashFreeze and Thunderblizzard. If @tavwtby @metagraphica @EastonSN+ @Mr. Windcredible! @WinterWolf @Spanks45 @WxWatcher007 and anyone else from CT i can't think of off the top of my head has any, lmk in the next few hours if u got em, thanks.

2.2" final North Haven, CT

It just wants to snow today. Thought that band was dying out thats been hanging out over North Haven all day but looks like its reintensifying the last few frames. Big flakes right now but its pretty light. 1.0" 31F First inch of the season.

coming down good now.

At least it looks like winter out there for the holidays, even though it wont last long. 0.7" 32F

I'm already closing in on 1. This small band is expanding a bit and slowly pushing west over the North Haven/Madison area.

0.5" light to occasionally moderate snow. Everythings white now, roads mostly wet but starting to get white.

Epic, bought to take a weenie drive to east haven to see the slightly heavier white rain and wet roads.

Steady snow picking up a bit on intensity. White rain mostly though, roads are wet. Non paved surfaces starting to stick. Getting ready to hunker down. 34F

lol damn I've been in the low 20s multiple times so far. 22 coldest day this season, occurred last week and this morning.
