Guest Pamela Posted December 10, 2014 Share Posted December 10, 2014 For the uninitiated: Visibility greater than 1/2 mile: Light snow Visibility between 1/4 mile & 1/2 mile: Moderate snow Visibility under 1/4 mile: Heavy snow Now sometimes the rate at which the snow accumulates can be a gauge of snowfall intensity...the general rules of thumb in this area are as follows: Light snow: Snow accumulates at less than 1 inch per hour Moderate snow: Snow accumulates at about 1 inch per hour Heavy snow: Snow accumulates at greater than 1 inch per hour Very heavy snow: Usually when snow accumulates at greater than 2 inches per hour Link to comment Share on other sites More sharing options...
IrishRob17 Posted December 10, 2014 Share Posted December 10, 2014 Light snow 35. Bordering on what passes for moderate on this forum which means visibility less than 14 miles. Ain't that the truth! Well played. Light snow off and on since this morning, currently off. Link to comment Share on other sites More sharing options...

Guest Pamela Posted December 10, 2014 Share Posted December 10, 2014 So far the highest snow totals with this storm seem to be from LI. That's a little ironic. I didn't see an OKX PNS from Upton...but with 1.0 inches being recorded Monday afternoon at the Mt Sinai co-op...your statement may have verified...but I'm not sure.

Snowshack Posted December 10, 2014 Share Posted December 10, 2014 Have gone through mt Sinai twice monday, I think it's generous to say that 1" must have been extremely localized. Link to comment Share on other sites More sharing options...

tdp146 Posted December 10, 2014 Share Posted December 10, 2014 For the uninitiated: Visibility greater than 1/2 mile: Light snow Visibility between 1/4 mile & 1/2 mile: Moderate snow Visibility under 1/4 mile: Heavy snow I feel like the above can't be repeated enough. If you typically make observations from the same location- find some landmarks that are 1/4 mile and then 1/2 mile away from you. I use specific telephone poles when I am at my house. With that said- I am currently at work at 7 world trade and I can still make out some buildings on the other side of the Hudson- so its light snow.

rcad1 Posted December 10, 2014 Share Posted December 10, 2014 Light to mod snow here in western Nassau temp down to 34. If we could just get the temperature to drop some more the snow might start accumulating. .. Link to comment Share on other sites More sharing options...
Guest Pamela Posted December 10, 2014 Share Posted December 10, 2014 Have gone through mt Sinai twice monday, I think it's generous to say that 1" must have been extremely localized. I absolutely agree. I'm not far away from the station and if I had half that amount it was a lot. I think the observer just rounds things off on his reports...though he usually rounds them off in the other direction. Link to comment Share on other sites More sharing options...
LongBeachSurfFreak Posted December 10, 2014 Share Posted December 10, 2014 Very very light snow in wantagh. Tiny flakes making down to sea level means it's pretty cold aloft. We should see some accums after dark in decent rates Link to comment Share on other sites More sharing options...

REDMK6GLI Posted December 10, 2014 Share Posted December 10, 2014 For the uninitiated: Visibility greater than 1/2 mile: Light snow Visibility between 1/4 mile & 1/2 mile: Moderate snow Visibility under 1/4 mile: Heavy snow This cannot be hammered home enough. Many times during snow events some say "its ripping snow" and in actuality may be moderate at best. Link to comment Share on other sites More sharing options...
Guest Pamela Posted December 10, 2014 Share Posted December 10, 2014 Perhaps this is just some quirk of the radar, but: Overzealous observer: "I'm getting heavy snow now!" <an hour later> "I'm getting incredibly heavy snow now!" <an hour after that> "I'm getting the heaviest snow ever!!! Total blizzard!!!" Dispassionate inquiry at the end of the 3 hours: "How much did you get total?" Overzealous: "Almost 1/4 of an inch!!!!" Link to comment Share on other sites More sharing options...
Nibor Posted December 10, 2014 Share Posted December 10, 2014 It's been "lightly" snowing here for a couple hours and is only now starting to accumulate on the cold surfaces. Link to comment Share on other sites More sharing options...

If you are tracking, season total is a whopping 0.1" I was at work and was unable to get a precise measurement...but there was an accident and a detour on my way home and I was re-routed all the way out to a town called "Middle Island" (surprisingly hilly!) and there did seem to be a pretty fair covering in the rural areas.

chietanen Posted December 10, 2014 Share Posted December 10, 2014 Now sometimes the rate at which the snow accumulates can be a gauge of snowfall intensity...the general rules of thumb in this area are as follows: Light snow: Snow accumulates at less than 1 inch per hour Moderate snow: Snow accumulates at about 1 inch per hour Heavy snow: Snow accumulates at greater than 1 inch per hour Very heavy snow: Usually when snow accumulates at greater than 2 inches per hour You forgot Lake effect snow: accumulates at 3-6" per hour Seriously though, thanks for your contributions to this forum lately. You certainly add a great deal of insight to the discussion and analysis.

IsentropicLift Posted December 10, 2014 Share Posted December 10, 2014 Light flurries continue in Ramsey. All grassy areas are covered. Probably officially around 0.50" total accumulation. Nothing on paved surfaces. Link to comment Share on other sites More sharing options...

Mixed rain & snow continues to fall in the Mt Sinai area of north central Suffolk at the moment...once again symptomatic of the almost dual problematic nature of getting good snows out here...especially prior to about mid January...the fact that the low has lingered rather than quickly pulled away has allowed the moisture to remain, but concurrently *not* allowed cold air to be drawn in on the backside...had the low moved away rapidly, colder air would have been brought down much faster...but the moisture would have been quickly shunted off to the east...as they say, damned if you do; damned if you don't.
