OBS and nowcast for a widespread 2-6" event significant impact event, mainly midnight-Noon Friday morning January 7, 2022

[CPcantmeasuresnow]

4.0 inches on the nose here in Highland Mills as of 8:20.

25° and snowing lightly. Probably about done here accumulation wise.

[lee59]

LaGuardia reported 8.4 inches.

[the_other_guy]

Interesting snowfall.

 

Approaching 6 inches but I noticed much less on my asphalt driveway. Maybe 4

 

Unusual for a very dry powdery snow

I am definitely thinking HREF is the best...  in short range. However not perfect. It lagged the past two events and yesterdays 12z is below. AXIS excellent but amounts a little low, probably due to banding,

Maybe also incorrect snow to liquid ratios? I'm not sure how accurate the measured liquid precipitation values are, but NYC stations aren't reporting huge numbers. They're all around 0.4". So if HREF is using 10:1, that matches up really well with those maps.

Just over 8.5” in wading river, LI north shore.  Still some light snow falling.  Nice quick hitter!

2N Smithtown, NY 9.1" as of 8:30am

Still snowing 28°

Looks like about 6" here.  Testament to all the monster storms of the 2000s/2010s that I didn't even measure.  I've turned into my parents/grandparents who poo-pooed every "storm" in the 80s (other than showing respect for 2/83), having the 60s and late 70s still fresh in their minds.

The snow was definitely more dense and difficult to shovel than expected (yeah, I know, advancing age), but seriously the bottom inch was liquid slush.  Didn't seem like the ground would have been warm enough for that to happen.

It must have really accumulated impressively for awhile.  Sanitation is here no earlier than 5AM yet almost all the accumulation was on top of the tossed lids rather than under.  When I observed it at 6AM I thought "moderately-heavy" but must have been better than I thought.

Anyway, enjoy the snow everyone.

I tried the look up... couldn't quickly find what we both wanted to know.

Still... there is no question this HREF is a good model.  I also think the Canadian did well... NAM3K, not so good  through the day cycles yesterday...actually disappointing.

CoCoRaHs numbers. I'll add the two days up tomorrow and post a final on the associated threads. Click the image for more detail. Now off line all day.

Thought the NWS and other forecasts did well - I'm sure there were some misses, but no significant busts I've seen. Not worth pasting the full list yet, IMO, as it's very preliminary, but it looks like a fairly uniform 4-6" in most of SNJ/CNJ/NNJ, except for Sussex/Warren/Morris, which were more like 2-4", as expected, and most of E PA was in the 3-5" range, except the Poconos/Lehigh Valley, which were more like 2-3". NYC/LI/CT were more like 5-8" with the winner looking like LGA Airport at 8.4" (still snowing on E LI /CT though).

5.7" final here...very fluffy snow

[MJO812]

Sun is trying to come out here

[jm1220]

Last few flurries here. I’m going with 8”. 

[nycwinter]

winter storm warning should have been put out by the nws for nyc last night we fell into that criteria when all is said and done..

[Byrdhousebv]

Finished up with 5.5". Just finished clearing the driveway, and what a beautiful morning outside!

[Rtd208]

Nice storm here. Picked up around 4.0"-5.0" of snow. 

[Euripides]

Full sunshine right now in south Old Bridge

[Yanksfan]

6 inches in Nutley. Good storm.

The areas of black top and concrete must still be fairly mild in temperature as they seem to have about half of what is on car tops and grass.

Temp was 35 degrees at my house last night before the snow started so ground temps were above freezing, hence the much higher accumulations on the colder surfaces. Had 6-7 inches on the cars, picnic table, etc but only about 3-4 inches on the sidewalk/driveway. 

[EasternLI]

Still light snow here. Waiting for it to stop to get a final measurement. 

[FPizz]

4.75" here in Branchburg.

Absolutely. Same thing

A few snow pics, including nighttime snow, a shot of the pond across the street, our house showing my fine shoveling (and the town already having plowed our street by 7 am), and the snow angel I made.
