OBS for NYC CP first measurable minor snowfall? 11A Fri 12/20-11A 12/21, embedded with surrounding area periodic minor accumulative snow

[MANDA]

I was only going with about 1-2” here so I am going to be “busting” low if this continues much longer.  Going to look and feel wintry here for several days that’s for sure.

Not if you were using regular gas. Super Unleaded.

The intensity isn’t there and it’s too warm. It’s still in the mid 30s. Maybe out of New Jersey somewhere, but east of the Hudson is doing nothing.

I don’t live east of the Hudson

Two schools of thought…run it out or keep adding stabilizer. For the snowblower i run it out. For the boat I keep the tank full and add stabilizer after the final fill up.

It's absolutely fine to run the blower out of gas. If it was super. Especially with Sta-Bil in it. Yes correct. I advise against it if it was regular gas.

If the 01Z HRRR (below) and RAP and the 0Z NAM (below) are right, we're going to get another 1-2" in most of CNJ/NNJ/NYC and even down to Philly and parts of SNJ.

 

Rgem too

It's not quite that simple.  In a perfect world, if one could truly run the engine "dry" of all fuel, that would be best, as no fuel means no oxidation of residual fuel by the O2 in air, which is what leads to polymerization of fuel, i.e., "gunk."  The problem with that is it's really hard to ensure the engine and carburetor are truly devoid of fuel by running until the engine stops and if there is any residual fuel in the carburetor, gunk can still form in a more concentrated state.  That's why many engine manufacturers recommend keeping the engine as close to full as possible with fresh fuel (so very little air/O2 are present) and adding a fuel stabilizer to it to reduce oxidation/polymerization forming gunk.  I know the link below is from an additive company which could be self serving, but with 40+ years in the chemical industry and being in charge of hundreds of gas powered engines of all types in managing factories, I do have some specific knowledge here.

27 w/ very light snow falling 

still 1.5” on the board

this is pure fluff falling. Not gonna take much to get an additional inch or so if rates increase a bit

Radar making the slightest of moves east but echos look pathetic. I just want this out of here at this point so we can move on to the next round of wasted 3 day cold. Maybe I’ll wake up to a coating.

Another shift east northeast on the hrrr

That is a correct statement. That is why I say always use super, and stabilizer. Because unless you pull the carb. And douche it out. You will eventually have issues if you just let it run out of gas using regular .

This system is really starting to crank.  We have moderate snow currently with 2.3”.  30F

[brooklynwx99]

the vort moving through over the next 6-12 hours should spark some decent snow over NNJ. likely some coatings up to 1-2”

Yep

At least whatever falls will stick. Temp dropping to freezing now and dew at 30., so we can wetbulb to around 31

Precip is much more impressive than what Radar shows here. Legit moderate snow+ with half mile visibilities at times..

This is a positive bust

back home in rockland snow on the ground, mostly grass, colder surfaces.  Nadda here in yonkers

Ratios are higher 10:1 with this batch.. If this verifies you will see lots of 2-4" amounts overnight

On the fuel thread. I have rebuilt many a gunked carberautor. I agree with everything said so far on the topic, though I must add that ethanol is the true killer of the carb. On all of my 2-stroke engines, I now use True-Fuel or a similar ethanol free additive. Since switching to ethanol free, I have never had to rebuild a single carb nor do I worry about filling the tank completely before winterizing. On my snowblower, I transfer the fuel to my lawnmower in the Spring. I find the 4-stroke much more foregiving with the ethanol fuel though for my really good 4-stroke equipment (non oil-mixed), I also go ethanol free. I have a weed wacker still running from the early 1980s thanks to true fuel. I really hope they finally ban ethanol. It's really bad for engines. And of course, road salt, which eats up cement medians as well as your tie rods, ends, and the rest of the undercarriage on your car.

Exactly. You know what your talking about.

Ok, kids, game on! We got 3/8" in the last hour for an hourly rate of - wait for it - 3/8" per hour, lol. Snowing moderately at 33F and accumulating everywhere except on paved surfaces - nice dendrites, so the snow growth aloft must be nice in the dendritic growth zone. Radar looks good for awhile, so 1-2" is certainly in reach. Let's see how it goes. My wife and I just went for a very nice walk outside - it's just gorgeous out there!

And another 3/8" this past hour giving up 3/4" so far.  Should definitely make my 1.25" prediction and will hopefully get to 2" if the models are correct.  Light to moderate snow continues at 33F, just warm enough to have minimal accumulations on paved surfaces, but it's forecast to drop to 32F by midnight for most of CNJ, with some more snow to come, so secondary/untreated roads and sidewalks/driveways could get slippery (but no major driving impacts expected outside of areas that get 3" or more well NW of 95).

Steady light snow continues. Just measured 2.3"

26.1°

Upton thinks the island gets an inch in the early morning hours. One can only hope

That’s why I said you have a good shot of snow. if you’re east of the Hudson nothing’s happening.

 

Why is that a controversial statement all snow?
