I'm just curious... When y'all measure your snow.... How do you differentiate between .8" and .75 or just 1.0 for that matter? What are we using to measure snowflakes with such precision? 

I'm usually in 16ths of an inch or millimeters if I'm feeling adventurous; I have more than one ruler in my quiver.  There's a wee bit of rounding in converting to tenths of an inch.  I don't do quarters, so a full .75" would be .8".  An eighth of an inch is .1"  5 millimeters is .2"

Get yourself a westcott ruler

It's not the second coming of the blizzard of '78, but we might squeeze out another 2 or 3 tenths after midnight.

It's hard to find one where the scale starts at the end of the ruler.  There's usually a gap before the 0-line.  Of course you can measure the gap and remember to add it... pretty simple if it's = 0.1", but a bit of a pain for measuring small amounts if the gap is any larger.  It is possible to think way too hard about this and I have allowed myself that luxury.

I picked up 3” just east of KHVN this weekend for a seasonal total so far of 13.0”.

1 inch this evening total for the day here 1.75. Was expecting more this evening.

In general, I think most forecast models, almost at any time frame, were fairly reliable.  If you relied on future radar, not so accurate.  Future radar duped me once again.  It showed a potential for 3-5" from afternoon into the evening...

Surprised you're that low-BDR is closer to 20 inches STD

What are they at for the season now.

[donsutherland1]

The RGEM had the best QPF forecast for the January 18th event while the ECMWF was a close second. The EC-AI had 0.39".

That is such a BS measurement. Almost all the other places in the boroughs measured in between 1.5 to 3 inches today, a combination of both the snow from the morning and from the evening. If they measured properly, they would have had more than 1 inch. Their measurement problems have become so exacerbated since the start of the decade. They’ve consistently been, on average like 1-2” less than nearby areas in every storm, and it adds up. They should either measure somewhere else in the park or maybe they should measure in Riverside park on the west side where it’s more expansive. We’ve seen this time and again now.

Lol they are determined to keep it under 10. 

[wthrmn654]

Something to keep in mind and we do this every single time.... when snow events have borderline temps for nearly the entire event, on top of storms is a glancing blue,   totals should be half of what models depict... on top of wet ground versus dry ground don't accumulate nearly as easy. 

 

But if heavy enough or banding, it can overcome those issues eventually. 

[The 4 Seasons]

If anyone has any snowfall totals for Jan 18th ONLY, let me know, ill be doing maps for yesterdays system. 

These are the snowfall totals for the Jan 17th over performer. This only for the Saturday Jan 17th event  Thanks to everyone who sent me reports, they were useful and i tried to include most of them if they could fit. 

You can always find all these maps along with CT and SNE here

With the Sunday system I had .33" melted which yielded 2.8" snow.  Ratio of 8.5:1.  First part of the day had lower ratios and late afternoon switched to high ratios. 

Two day event total liquid: .61".  Two day event snowfall: 6.2".

Yep I measured around 2 right near the park
