The dry air issue has been discussed enough, but looking at the bottom of this radar view from KENX (Albany), you'd think LI got clobbered today:

Fun stuff.

 

Too bad we can’t shovel what falls at the 10000 ft or whatever level that radar beam crosses our area. :( 

There was no crazy confluence here today but plenty of dry low and mid level air. Soundings were brutal and made it obvious those GFS snow maps were way overdone.

I ended up with roughly an inch in Point Pleasant Beach.  It was a bad bust by the nws for my area as they had us in 4-6 all day.  The gradient got the sickest between toms river and manahawkin.  

They missed on the gradient by like 30 miles.   It's not a bad bust.   It's just a really hard forecast.

Atlantic City picked up 13.0” of snow while both Newark and New York City received none. That surpassed the old record of February 24, 1989 when Atlantic City was buried by 12.3" of snow while Newark and NYC received none

February 1989 was the exact event I was thinking of-- except I thought they received 19" in that? Philly got about 10"?

Anyway it looks like our models have improved somewhat since then, we had a forecast of 6-8 inches leading right up to the storm.  It was a 6-8" virga snowstorm for us lol.  It was the opposite kind of bust compared to December 1989 when we were predicted to get 6-8" of snow and the secondary formed right overhead and we got thunder, lightning and rain instead!

Are you familiar with both of these events, Don?  They were the two most negative busts during the 1980s.

Also, Correct me if I'm wrong: Atlantic City calendar day snowfall yesterday was their 7th highest in their period of record.

Yeah, we had the Feb 2017 blizzard a day after the record 60°+ warmth.

https://www.weather.gov/okx/Blizzard_Feb92017

  • Blizzard conditions occurred over Long Island, Southern Connecticut, and coastal portions of the Lower Hudson Valley from after sunrise into the late afternoon hours on February 9, 2017.
    • Snowfall totals ranged from 6" across portions of northeast New Jersey to around 10" in New York City to 12-16" across Long Island, southern Connecticut, and the Lower Hudson Valley. 
    • Thundersnow was observed across portions of Long Island and southern Connecticut. 
    • Snowfall rates range from 1 to 3 inches per hour with locally 4 inches per hour at times. 
  • The blizzard brought delays and cancellations to the regions transportations systems as well as numerous accidents on roadways. 
    • Approximately 2,000 flight cancellations and numerous delays occurred at the three major airports, Kennedy, Newark, and LaGuardia.
    • The Long Island Railroad had systemwide delays and cancelled 20 trains.
    • Multiple car accidents occurred on roads as well as several hundred rescues were performed by police/fire on Long Island. 

 

 Other Facts 
  • A cold front associated with low pressure across southeast Canada moved across the region on Wednesday February 8. Behind the cold front, an upper level trough amplfied across the midwest. Energy within this trough acted on the cold front to develop a new low pressure across the Middle Atlantic. This low pressure rapidly intensified as it moved off the Delmarva coast the morning of Thursday February 9 and then to the south and east of Long Island later later that day.
  • The southeast coast of Long Island including the eastern Hamptons and Montauk were warmer at the onset of the storm. Montauk was 41 degrees between 9 and 10 am in rain, before dropping to around 32 by 11 am in heavy snow. 
  • The day before the blizzard (Wednesday February 8), record warmth was observed across the Tri-State area. Record highs ranged from 62 at Central Park, NY to 65 at Newark, NJ.  Temperatures dropped 30-40 degrees in 12-15 hours as readings were in the middle-upper 20s during the height of the blizzard.

One of the best storms I've ever seen, like a half version of Jan 2016, all day zero visibility!

Wasnt that the storm that set the surge record in Boston too?

I know there isn’t much stat support but these Day before near record warmth followed a day later by a snow storm, in my opinion  are not uncommon, and associated with leftover Large PW near the front and an oncoming intensifying short wave.

For me the best warm day to snow is April Fools 1997. It was in the mid 50's here during the day and by about midnight there was 17" of glop on the ground. After a warm March and nearly snowless winter the soil temps were nearly 50* already and the trees were leafing out. It was a disaster...
