Forgive the off topic question (but since this where folks are...)

Does anyone know where you can get historic hourly data for a station? In this case, Central Park. Honestly would only want the past month or so, but will take more if available.

But for a good part of that quarter inch of freezing rain along the north shore, the NAM forecast soundings shows a 50 - 100mb deep sub freezing layer (decreasing over time) from the surface up*.  I forget the magic numbers, but I'd imagine that some of that fzr would be sleet.  3k NAM does eventually get to an obvious fzr sounding and then a wee bit of plain drizzle before things cool again.

I'll take a stand and go with  4" in my neighborhood.  How much it packs down with the phase shifts is TBD.

 

*Caveat is I'm extrapolating from the skew-Ts on the free TT site.  Hard to be precise on some of that fine stuff.

NAM should have stuck to its guns.  It was showing us not getting above freezing (or barely getting above freezing) in yesterdays runs before it lost the plot overnight.

As for my 4", not looking good.

31.2° here with some occasional light freezing rain. Been stuck between 31.1° and a max of 31.4° for a few hours.  Not the most efficient ice accretions, but its telling that the snow in the trees hasn't budged after several hours of rain.

Very icy out currently. Everything untreated has a thick glaze to it 

[uofmiami]

County plow removing any slush from the county maintained road outside my office.  I'm sure they'll salt afterwards & road should be good.

[jimbo073]

How is the GSP, I 78 and NJTP? They should be fine and ice free since they are treated. Correct?

Thanks. Was hoping not to have to pull day by day, but works to get a week or so.

Central Park's accumulation is 1.6" so far.

[psv88]

Amazing how steady the temperature has been for the past 4-5 hours. Just holding at 31, barely any movement at all.

HREF mean was fairly close in the end.  We simply failed on the upside potential which I felt was good as models tend to underdo WAA snows in weak setups like this...that idea worked in PHL/BWI but not here

Here are the latest Snowfall (storm total) reports for our 6 climate sites.

 

EWR - 2.1

NYC - 1.6

LGA - 1.9

JFK - 2.0

ISP - 2.1

BDR - 2.0

Amazing in these small storms how that extra half inch to an inch always appears over Newark then disappears in the 5 miles to Central Park and reappears again in the 5 miles to LaGuardia.

It must have something to do with the high mountain ranges in between Newark and LaGuardia.

Yup. Dca and bwi both got 4+

[jm1220]

If we’re getting any flip back to snow, this batch in E NJ should clip most of the island and hopefully a wintry ending.

There are many cases of SW-NE moving weak forcing events which overperformed in DCA/BWI and zonked out here...some have even done the reverse....1/19/02 is a good example of one that pulsed over DCA they had 5-10 inches and here we got the generally forecast 2-3...there are many others too but that one stands out for sure.  12/90 is one that did the opposite, it badly disappointed down there and pulsed up here and we saw 5-8.

Almost all models still show a bit more snow later from NYC on NW with around an inch more Westchester on north.

Don't need a model to know that.  I've seen this situation many times where snow ends as rain but the temperatures fail to budge above freezing and I don't recall it ever not ending as a period of snow.  Whether its a coating on the ice or another inch, it's inevitable.

[ForestHillWx]

Freezing mess at the office in Basking Ridge. My brother in Franklin (Sussex) reports moderate snow and approaching 6” as he is currently clearing/plowing.

Midwest Regional Climate Center has hourly data.

And 12/90 was forecast to be 1 to 3 as of that morning before being bumped to 3 to 6 later that afternoon so a definite overperformer

23° and rain for hours SUX! Even with the snow that's still nice and white under the crust it still sux.

snowing again here in Nanuet

Thanks, Don!

1.5" then some sleet, Frz rain.  Pretty huge bust when the forecast was 4-6" here. 

Overperformed with the last storm with the 4.5" I got, so I guess it evened out   

[uofmiami]

Sleeting in Great Neck now

Same here, I’m back to 30F.

How sad is it when LA, MS, AR, AL,TN and everyone else in between got more than us.  We have to beg for a couple inches

24 and still steady light snow. Eyeballing about 3. 

[lee59]

Wind has picked up substantially and the temperature has quickly dropped from 31.7 to 29.9, everything freezing over with light precip falling.
