The Allsnow Blizzard of 2026

Recommended Posts

After a few hours of light rain/snow/mix with temps in the 35-36F range, the temp has dropped to 33F over the last hour or so and the snow intensity picked up then and accumulation just started on grass/cars/colder surfaces; paved surfaces might take another hour or so. If you're thinking of heading out now, you might want to reconsider - even if salted roads are ok for a few more hours, visibility is becoming an issue now.

Also, here's our starting point for snowfall, as we still have 1-2" of snow/sleet on our property, which admittedly is on the shady side, but damn, that's about 35 days straight with <1" on the ground and that's going to go for at least another 7 days now. Sweet!

All just tools for trends not exact qpf or snow totals as the storm is in progeess - go with the actual obs

Just a lot of support from better near term guidance showing the major global models were too east

It was discussed earlier in the interior thread, but up until the very short term models, most models miss or misalign the northern edge which always ends up another jackpot area. There always seems to be a stronger area of lift right at the area where the strongest precip starts to fade. 

There's going to be a big band somewhere just north of you into Sussex County imo

Ratios is a big part of it. People in here always dismiss them. This will have them up north where you are. And further south and southeast there's more QPF in general to get them to their forecast. And then banding is sure to set up somewhere relentlessly allowing select areas make it to the high ends of their forecast.


.

NBM, which uses a combo of Kuchera and the Cobb method has overall ratios of 12-13 for the NJ coast and 15-17 NW of 95, which is part of the reason why the NBM is showing more snow per QPF than the 10:1 snowfall maps.  I can definitely see this, since once we overcome the early melting, the snow crystal growth dynamics in the DGZ should be great for low density/high ratio dendrites, especially after about 7 pm with temps below 32F in the whole column.  Only question then becomes how much crystal breakage do we see upon descent through a very windy column.  Will be interesting to see. 

Also, measuring the snow accurately will be tough once we get past 9-10 pm and winds really pick up.  Might have to use my technique of going to a huge field near me, which limits the "edge effects" one gets in most house properties with fences, trees, roads, etc. This was the only way I could get decent measurements for big storms with high winds like Jan-96, BDB and Jan-2016.

I posted this elsewhere but I will put it here also as I am looking for a little insight ,,,,,,,IF the MESOS earlier started to bum people out why would the NWS now increase amounts and issue blizzard warnings for Orange and Duchess counties which are well N n W of NYC ,,,,,,what are the experts looking at ? The HRRR ? something else ? Bueller ? anyone 

While the latest 12z GFS is now lower with QPF and more in line with
the Canadian and ECMWF, these global models are struggling with
banding. Current forecast QPF and Snow Amounts remained similar
to previous forecast which is more in line with hi res/HREF
guidance. Snow amount was derived using similar snow ratios to
the previous forecast. Much of the guidance including the NBM
appears to be too high. This was mannualy adjusted down to
10:1 or even a bit lower today, then increasing to 12-14:1 by
late tonight into daybreak Monday as colder air wraps around
the system. Using these ratios with generally 1.25 to 1.50
inches of QPF across the interior and 1.75 to 2.00 inches along
the coast resulted in a swath of about 20 to 24 inches of snow
for NYC and Long Island and 16 to 20 inches elsewhere. While
this is the expected amount, a few isolated readings of 30
inches are possible in the heaviest banding, mainly along the
coast.

Good luck have fun. Should be a great spot for this one.
