Yes.

It generally means they are predicting a general 6-10" from 7PM tonight till 7PM tomorrow northwest of Boston proper.

I don't think those numbers will materialize for you down there. Thinking more about the 4"-6" left to go for you before it done.

Heavy snow here!

Yea, I was just going to post that. Approaching 2".

I have about an inch of snow since 1:00 P.

I think you may end up being pleasantly surprised a little later.

Your spiking the ball way too early.

Your one of the biggest weenies I've ever met.

New York Weather Office

16"- 24" of snow is expected for NYC, northeast NJ, the Lower Hudson Valley, much of Nassau, and portions of southwest CT. 6"- 12" of snow for eastern Long Island and southeastern CT (lower amounts here due to potential for wintry mix or changeover to rain). Strong winds and low visibility with accumulating snow will make travel very difficult to impossible. Finally, widespread minor to moderate coastal flooding; locally major impacts possible Monday night.

Around 5-6 PM

Yes, right now it is. I'm talking a little later as the storm gets closer.

Watch, sleet will mix there. They are right on the water.

It's all good. It's just a discussion, not an argument. It's all good.

I never said it inflates the snow by large amounts, no. 12 Hour storms, not a big deal at all to have any significance. Usually, I start to see the discrepancies at 24 Hours duration storms and beyond. Which are of course are somewhat rare in itself.

That IAD is a combination of elevation 313 Feet and 6 hour measuring technique. I heard some rumors, not entirely sure if there true, that others measured every 3 hours and wiped off the board but I'm not even going to go there. When that happens, usually but not all the time, the Weather Bureau comes in and corrects the measuring error.

I'm not trying to state that. What you said is totally correct. Try to measure the snow a little before it ends if you can and if the snow ends before your original observation time then give that amount to the Weather Bureau. No problem. You said everything right.

Do you really think I'm the only weather observer that measures every 24 hours? There are many others not to mention COOPS that do this. Airports are in another a World of their own. Other weather spotters do measure every 6 hours like you do. This creates a discrepancy in storm totals. This is why there is ambiguity when it comes to snowfall measuring techniques.

I said only in that particular situation not others, such as a straight start to finish snowstorms. Doesn't matter whether the snow is wet, fluffy, or normal ratio... (Mic Drop)

I would record that data which is fine in that particular situation. But you won't have much left to show for it. This is where problems occurs, someone will actually get 6" that stays while your 6" will be down to about 1" at observation time.

What you just stated is correct in that particular situation. You may have received a total what ever that may have been and you can record that. However, as you alluded to you only have about 3" or so left over. True that's a depth but if you put down the total and only have 3" left over it will look pretty strange on a report where someone actually have the total you reported and has a simliar amount left on the ground verses you blown off or beaten down amount left over. There are examples of this in the COOP Data.

By altering what would have naturally settled given the ding conditions, you are therefore manipulating it. The temperature analogy is not a really good analogy to this particular situation. You can give a high and low temp/day, that's fine.

One problem though, they both are not one in the same, therefore not consistent. One is more natural observation, the other is more manipulative.

This has nothing to do with Road Crews Ray. This has to do with science/Meteorology. It's called Observing mother nature not how much a plow operator is going to get paid or manipulating the snow to see what would have been had it never settled naturally.
