NWS responded as follows:

“The 0.15" was an automated measurement determined to be erroneous, likely from snowmelt getting into the gauge. A trace of snow was reported by our Park observers after 1 pm, and the storm total for the event is 19.7.”

Thank you for this update.

The siting of the ASOS in Central Park is poor.   A large chunk of heavy, wet snow could easily fall into the gauge from nearby trees during a wind gust.   In addition, the lack of any augmentation and backup causes periodic erroneous measurements.   The AWPAGs in ASOS are much better with frozen precipitation than the heated tipping buckets, but they are not foolproof.  NYC deserves better.  
 

While the mesoscale models and NBM forecasted more accurately along the coast, the ECMWF and UKMET did the best in western NJ and eastern PA.   Both opposing model solutions were accurate and inaccurate, at the same time.  A Blizzard Warning 20+ miles west of NYC was not needed as the criteria was never met.  
 

In Somerset County, NJ I measured 12”, the NWS forecasted 15-26” and the NBM consistently forecasted about 20”.   The errors were even greater further west.
 

All in all an impressive and well forecast storm.   It’s too bad the climatological record needs to be QCd, corrected and amended post-event.

The ASOS at EWR is in Union County on the southeast corner of the airport property.   Snow is measured approximately 2 miles northeast of the ASOS in Essex County.   It’s still on airport property but the county boundary slices the airport in half.

Snowfall totals map for this historic February 22-23, 2026 Blizzard.

As always thanks for everyone who sent me reports. Data is from here, cocorahs, COOP and official sites. This L Northeast is all i have done so far after about 16 hours it was a massive undertaking. I tried to include all reports but some don't fit and had to be excluded. The site will be updated soon but these maps are not up yet. This will be the 2nd historic storm of the season and ill have everything including a full radar animation up on the site in the coming days. 

There is some incomplete data on the PNS and NWS snowfall maps so beware. BOX is only using 1-day cocorahs totals for some reason and not including both days, so a ton of the reports are very low that say "cocorahs" next to them. OKX did the same thing but instead of only including the 23rd they mostly just used the 22nd. 

On a technical note there is exactly 398 reports on here from well over 1,000 sifted through, probably closer to 2k. This was only the 4th time ever including a 40"+ snowfall contour for all the events i've done. Gotta say this is one the coolest looking snowfall maps ive ever produced. 

I mentioned earlier the forecast for CT was very good to great. For the overall region it was probably a C/C+?  Too low for SE MA/NJ even though i put 24"+ in text, that is not sufficient and it needed a whole new range of 24-36+. Too high for NW MA and Catskills. Our final call was the same as the first but i had a 2nd and final update ready to go where i had SE MA/NJ in a 24-36" range but never posted/released it. I figured the first call was good and didn't want to change the map if i didnt have to but in retrospect im kicking myself a bit for not doing so. Oh well. 

The Tri-State only map is not done yet but will be coming soon. If there is anything missing or needs to be adjusted let me know. With these big storms, this probably wont be the true final....with an error or two or additional/changed reports needed.

Not buying it. Look at the radar from 1-3pm yesterday and Central park was under some very heavy echoes and I believe also reported heavy snow. You don't get a trace from that in a two hour period.

I also could be wrong on this, but I thought the precipitation from 1251 to 351 was .28. The snowfall measurement was at 1 PM for 19.7 inches so the math doesn't work.
 

Again, I'm grateful they got as close as they did, much better than some of the abominations in the past.

Phenomenal job with these. So above and beyond any other maps you can find online for storm totals.

Analyzed lowest pressure was 966MB.  Analyzed track was about 60 miles south of the BM.  

Full warm seclusion.

 

Makes sense on the track.  Winds were solid but not epic.  March 2017 had more consistent/ stronger winds inland despite being 10mb weaker but crossed east LI and into east SNE so low was far closer.
