SnowGoose69 Posted December 28, 2017 Share Posted December 28, 2017 Just now, SnoSki14 said: I don't see how the ratios would be greater than 15:1 as anything above that is extremely rare around here. As someone stated, lower temps don't equal higher ratios. This may end up being an inch at best but with how dry the air is and the amount of virga likely, it may only be a dusting (>0.5"). 700mb temps are -20c. So I would not think ratios will be 20 to 1. 15 to 1 is possible though Link to comment Share on other sites More sharing options...

mikem81 Posted December 28, 2017 Share Posted December 28, 2017 18Z NAM much improved from 12Z. About .2 of precip Link to comment Share on other sites More sharing options...
jm1220 Posted December 28, 2017 Share Posted December 28, 2017 This isn’t something I’d write off for maybe a few inches on the coast. It’s a vigorous wave aloft and wouldn’t take much moisture from the Atlantic for a decent period of snow. The best shot is on Long Island for enhancement.

purduewx80 Posted December 28, 2017 Share Posted December 28, 2017 Some hints of an ocean-effect band *just* east of the city (very close to JFK) on Saturday morning (see 3KM NAM, RPM, HRGEM). The low level convergence would need to align just right, but the temp profiles in low levels are killer for some high-ratio fluff, especially on Long Island.

snowman19 Posted December 28, 2017 Share Posted December 28, 2017 Besides Long Island and eastern New England, this is a dusting/snow showers. There may be spots north and west of the city that don’t even see a dusting Link to comment Share on other sites More sharing options...

There is light southerly flow which will help L.I. .2 sneaks in just east of the city with .4 now into Suffolk county. Could see as much as 3 just east of JFK with as much as 5 out on to the East end if the NAM is right. Link to comment Share on other sites More sharing options...

Things haven't really changed, it's still mainly a dusting to an inch for most of the area. The east end of LI might get a bit more, I'm not sure what ratios people think we're going to get but anything above 15:1 is a big stretch. The previous clipper systems were a lot more potent.

I think 1-2 is entirely possible based on a good portion of guidance from EWR to WRN Long Island. Far eastern Long Island has room to see over 3-4 but it’s too early given it’s going come down to how quick the surface low forms and other factors the NAM/RGEM should see better tomorrow Link to comment Share on other sites More sharing options...

That was likely a bad ASOS liquid equivalent. I remember that event and it was about 20-25 to 1 on average I think. I think this one may be up to 20 to 1 in some areas.

I do recall though that it was slow to get going and that panic mode was setting in around 8-10pm because of a dry slot that formed. Oddly enough the miller B a week later had almost the same thing happen. . Once again forecast soundings suggest this event will reach the ground quickly Link to comment Share on other sites More sharing options...

I think it was the one where it snowed most of the night and it was still snowing hard early in the morning as the sun was trying to come out- sunrise snow- it looked pink as it was coming down with the rising sun in the background.
