The Allsnow Blizzard of 2026

[donsutherland1]

The ground is coated from the light snow in Larchmont.

light snow here 32

[UKWeatherGeek.]

Measurement will be tricky but think most are being conservative here. Models often struggle with detail of bands, that combined with 1:11-1:12 ratios, the 12-18” estimations for metro are underdone. I’d say 16-22” is more accurate.

Combine the threads - Storm Discussion should include obs.  Just my 2 cents

36/36

[SnoSki14]

The light precip and rain/mix for most will continue until around 4PM and then temps crash after that when the real storm arrives. 

Using the HRRR mostly from this point on.

Hrrr took a step back

@SACRUS was Jan 26–27, 2011 (– 19.0") the storm that shut down parts of Monmouth/Ocean County with totals around 30 inches?

[My notes show 17.75 inches, here in Perth Amboy.]

@weatherpruf @RU848789 Do you guys remember it? My sister lived in Bradley Beach and could not get out of her property for days.

I believe 12-15” is a good call for nyc itself

Yeah I don’t like the split in threads gotta go back and forth 

[Prue11]

Places will bust low and places will bust high. Get under the right band and you’ll do good

[Snowman92]

Same , need to keep 2 tabs open

[BoulderWX]

Anyone have a good national or regional radar

I think 18”-22” is a better call for Nyc. The NWS is predicting 20” and I think they might be playing it slightly conservative. I think Nyc is going to score on this one

Current - the 32 F isotherm line roughly runs from western Passaic County westward to the Poconos.

Deformation zones will see 36+ with outside it half the amount.

36 is a stretch. I don’t believe these big totals are as widespread as forecasted

a bit east which affects western sections

[kat5hurricane]

Some of the models have cut back a bit but it's noise at this point, this is still a really big storm with 12-20 areawide.

I’m one of those western sections in this storm

and I’d take that and run!

It’s an interesting forecast where I am near the Delaware River with only the short term Mesos calling for big snows here (12-18”) whereas the globals and some mesos are calling for 8-12”.  The IVT will be the key out here for me and other NW areas.  The cutoff will be right through my general area I believe.

12z HRRR concurs with the Delaware River cutoff for the big snows.

Again ratios for a good 6-8hrs will likely be higher than 10:1

I'm playing it conservative but trust the NWS too. 

This is one instance where an overperformance wouldn't surprise me. How often do we see a 970mb low inside the BM.

Deformation zones are not widespread. Very easy to get 36 in a powerhouse like this.

Here are my thoughts….i’m going with the RGEM. RGEM all the way. It’s been the most consistent for days and hasn’t budged. Great model. Makes the most sense. I think the NAM is about to go down in an epic flaming dumpster fire. It’s going to have its hugest bust ever. GFS has been downgrading amounts since Friday evening. Ride the RGEM
 
6z RGEM: https://www.pivotalweather.com/model.php?m=rdps&p=sn10_acc-imp&rh=2026022206&fh=48&r=us_ne&dpdt=&mc=&pwplus=1

Someone could drop a million dollars in your lap and you would be concerned about currency devaluation.

Deformation banding will gift some with huge totals and rob others - always the case its not such a uniform distribution as the globals and other models show.  QPF in general will be 1-1.4 aread wide ( 8-14 or so) and under those heaviest bands/banding  up to and exceeding 2-2.5 LE and that's where the >18-24 inches totals in those areas the target has been depicted in the Ocean - Monmouth cty and LI/SNE areas.

coming more into reality-some of the GFS/NAM totals are likely over done

I agree even though I wish it was true
